The topography of Colombia is dominated by the Andes. While manifested as a single mountain range from Ecuador southwards, the mountains split into three ranges (or cordilleras) near the Colombia/Ecuador border, and these three ranges span the length of Colombia from this southern border towards Venezuela in the northeast. Despite the vast amount of territory contained by these cordilleras (and their associated river valleys), around half of Colombia consists of flat lowlands, especially east of the mountains. Burrowing Owls In general, this eastern half of Colombia consists of the humid Amazon rainforest to the south and drier plains to the north. These plains (los llanos in Spanish) are productive areas for raising cattle and other livestock, similar to the plains found in parts of Argentina, Paraguay, Uruguay, and Brazil in the south of the continent. Forests are more limited and the land is a mosaic of seasonal wetlands, open savannahs, palm swamps and gallery forest along the productive rivers. After the conclusion of the main tour, four travellers joined local guide Cris and I for a visit to these eastern plains. We would be staying at Juan Solito Ecolodge, located within a massive ranch called Hato La Aurora. Cattle roam across the landscape, coexisting with the abundant wildlife that thrives in this region. The ecological health of this ranch is relatively high since the cattle are at a low density and all of the original forest cover has been preserved. Jaguars in particular can be found in good numbers while Green Anacondas are frequently observed in the numerous wetlands dotting the property. Orinoco Geese Sharp-tailed Ibis Our visit would be coinciding with the dry season. While at certain times of the year the wetlands stretch across the landscape, at this time of year they are much reduced in size. This concentrates the many mammals, reptiles and birds that rely on these life-giving wetlands. Capybaras (Hydrochoerus hydrochaeris) Scarlet Ibises The temperatures are very high here in the lowlands and so we prioritized being out early and late in the day when species are the most active. Dawn in this region is spectacular with nearly every bird being vocal and we typically crossed the 100 species threshold each day by 8 or 9 AM. Burnished-buff Tanager Black-crested Antshrike Masked Cardinal Double-striped Thick-knee Nacunda Nighthawk Several birds found here are endemic to the plains of northeastern Colombia and western Venezuela, including Pale-headed Jacamar, Venezuelan Troupial, Sharp-tailed Ibis, Crestless Curassow and White-bearded Flycatcher. We succeeded with all of them, with the jacamar, flycatcher and ibis easily found around the lodge! Pale-headed Jacamar White-bearded Flycatcher Venezuelan Troupial Much of our exploration was done from a safari-style pick-up truck that had two rows of padded seats in the bed and a roof sheltering us from the sun. Our truck We followed dirt tracks throughout the vast expanses of the ranch, visiting various wetlands and forest habitats. The wetland birds were especially numerous - seven species of ibis, hundreds of White-faced and Black-bellied Whistling-Ducks, herds of Capybaras, innumerable herons, egrets and jacanas, and much more. In our four-night stay we found around 180 bird species. Scarlet Macaw Large-billed Tern Capybara (Hydrochoerus hydrochaeris) Roseate Spoonbill We kept an eye out for reptiles and encountered quite a few species, including a couple of big targets, figuratively and literally! We found an adult Orinoco Crocodile (along with dozens of Spectacled Caimans). The Orinoco Crocodile is a critically endangered species endemic to this ecoregion, and only a few hundred remain in the wild. Orinoco Crocodile (Crocodylus intermedius) Orinoco Crocodile (Crocodylus intermedius) The other "big" target was Green Anaconda, and we succeeded with finding three individuals! Most impressive was a huge female, likely over 5 meters in length, that was mating with a much smaller male in a shallow wetland. This was, by far, the biggest snake I had ever seen. Green Anaconda (Eunectes murinus) Green Anaconda Other reptile highlights included Cryptic Golden Tegu and Savannah Side-necked Turtle. Savannah Side-necked Turtle (Podocnemis vogli) Though our main target was undoubtedly the Jaguar, I still placed the odds of finding this secretive species fairly low. We had struck out on the previous trip in 2022 and I did not want to get my hopes up. And during our first few days, we had no luck despite spending some time in some of the better areas where they are occasionally seen. Then, one afternoon as we were bumping along a dirt track, our local guide Jovani suddenly shout-whispered "Jaguar! Jaguar!". There, only 50 meters from us, was this absolutely magnificent Jaguar slinking through the grasses. The encounter lasted only around 15 seconds or so but it was unforgettable. Jaguar (Panthera onca) Jaguar (Panthera onca) The Jaguar was an exciting way to close out an amazing tour extension to the Juan Solito Ecolodge. I hope to return one day!
I have recently returned from an excellent tour to Colombia that I led for Quest Nature Tours. This was my third time guiding in Colombia, following excellent trips in 2020 and 2022. Those previous tours covered a lot of ground, in the eastern Andes near Bogotá, the Central Andes between Pereira and Medellín, and the Santa Marta Mountains and Guajira Desert located in the far north. This 2025 tour was different as we only focused on the Central Andes portion over ten days. This eliminated all of the internal flights, it cut down on driving time, and it allowed us to have more time to thoroughly explore each site. Following the main tour, I traveled to the Juan Solito Ecolodge in the northeast of the country with four of the travellers and our local guide Cris, where we had four nights in the llanos to search for a huge array of birds as well as other specialties of the region including Jaguar and Green Anaconda. Crescent-faced Antpitta Andean Cock-of-the-Rock Bar-crested Antshrike Twelve enthusiastic travellers joined Cris and I in the town of La Florida, situated a short drive from the beautiful montane forests of Otún Quimbaya. As dawn broke, a Rufous-bellied Nighthawk flew over the clearing at El Cedral, and we experienced a delicious Colombian breakfast while listening to the dawn chorus. For the rest of the morning we marvelled at mixed bird flocks and enjoyed the high diversity of this region. The Cauca Guan is an endangered species found in a small region of the central Andes of Colombia, and we succeeded with amazing views of them. We also studied White-capped Tanagers, Red-ruffed Fruitcrows, Andean Motmots and Pale-eyed Thrushes, while mixed flocks contained the endemic Multicoloured Tanager and scarce flycatchers like the Variegated Bristle-Tyrant and Bronze-olive Pygmy-Tyrant. Meanwhile, Torrent Ducks were easily found along the Río Otún which was flowing quickly after the recent rains. A feast for the senses! Cauca Guans Vettius sp. Black Phoebe Andean Motmot Red-ruffed Fruitcrow Torrent Duck We moved on to a site just west of Manizales called Hotel Tinamú Birding Nature Reserve. This is a relatively new property that I had never visited before. It consists of regenerating dry forest in an area that formerly contained coffee plantations, and the species composition is much different than the humid montane forest we had just left at Otún Quimbaya. Our comfortable rooms were located in a clearing in the forest, and active tanager and hummingbird feeders could be enjoyed from our front porches. Blue-gray Tanager Monarch (Danaus plexippus) Some of the bird specialties at Hotel Tinamú include a couple of localized species that have been trained to come into feeding stations - the Gray-headed Dove and Blue-lored Antbird (we succeeded with both). We found leks of Golden-collared Manakin and Green Hermit, while birding the road in scrubbier areas produced Colombian Speckle-breasted Wren, Bar-crested Antshrike, Ultramarine Grosbeak and, best of all, a quartet of Greyish Piculets (an endemic species to this valley) which provided incredible, "walk-away" views. Blue-lored Antbird Streaked Flycatcher Grayish Piculets One evening, I set up my moth trap in the garden which produced a nice variety of moths, rove beetles, stone flies, leafhoppers, scarabs and much more! Unidentified leafhopper (family Cicadellidae) Eois camptographata Unidentified stonefly (family Perlidae) Unidentified leafhopper (family Cicadellidae) Pelidnota prasina Oxyptera laeta We moved eastwards towards the imposing Los Nevados National Park, where several volcanoes reach high above 4000 m in elevation. Before reaching these heights, we spent two days in montane forest at different elevations: Owl's Watch at around 2600 m, and Hacienda El Bosque at 3100 m. This gave our bodies time to acclimate to the elevation differences, while it also afforded us the chance to find a high diversity of birds that we wouldn't see elsewhere on the tour. Hooded Mountain-Tanager Blue-capped Tanager At Owl's Watch we had amazing encounters with Black-billed Mountain-Toucans and an endemic Brown-banded Antpitta, both of which came into feeding stations. Though we dealt with persistent rain and fog this day, the birding was still very active with many species including White-throated Daggerbill, Rufous-crowned Tody-Flycatcher, a dozen hummingbird species and a recently-fledged White-capped Dipper. Black-billed Mountain-Toucan Long-tailed Sylph Rufous-crowned Tody-Flycatcher Hacienda El Bosque is a must-visit site for any birder in the Manizales area. This property was amazing during my first visit in 2020 and it has only been improved. The star of the show, a Crescent-faced Antpitta, is still attending a feeding station, as are Gray-breasted Mountain-Toucans, Equatorial Antpittas, Andean and Sickle-winged Guans, White-browed Spinetails, Barred Fruiteaters, Hooded Mountain-Tanagers and Grass Wrens, among other species! And to top it off, a new restaurant has been built at the upper elevations where we enjoyed one of the best lunches of the trip. Crescent-faced Antpitta Gray-breasted Mountain-Toucan Gray-breasted Mountain-Toucan Sickle-winged Guan Grass Wren Yellow-bellied Chat-Tyrant Barred Fruiteater Hummingbird diversity was high and we observed the species with the longest bill (Sword-billed Hummingbird) and the shortest bill (Purple-backed Thornbill). A distant Andean Pygmy-Owl called from up the hillside and we found a nice mixed flock as well. We all came away with many highlights and photos from Hacienda El Bosque! Sword-billed Hummingbird Rufous-breasted Chat-Tyrant Our base for the next two nights was the picturesque Termales del Ruiz hotel, situated in the upper reaches of the cloud forest at 3500 m. Not only is this hotel conveniently located to explore Los Nevados National Park, but the hummingbird feeders are very active while the birding along the roadside can be excellent. And of course, going for a dip in the lovely waters of the hot springs feels fantastic after a day of birding. Tawny Antpitta We lucked out with clear weather during our morning near the gates for the national park. Overlooking Los Nevados National Park This was the highest elevation that we would see on this trip at 4138 m, and it is at this site where a unique hummingbird can be found. The Buffy Helmetcrest is a specialist of the páramo habitat and Los Nevados National Park is the only place in the world where it can be sought out. The temperatures are only a few degrees above freezing every single night of the year, and this solidly-built hummingbird can withstand these tough environmental conditions and even thrive in them. We experienced amazing views of a male Buffy Helmetcrest, along other high-elevation specialists like Andean Tit-Spinetail, Tawny Antpitta and Viridian Metaltail. Buffy Helmetcrest We explored some other habitats slightly lower down on this mountain. An alpine lake held several Andean Teals and Andean Ducks, while we successfully called in a Páramo Tapaculo to the roadside, allowing great views for everyone. Mixed flocks in the higher montane forest held species like Blue-backed Conebill, Great Sapphirewing, Scarlet-bellied Mountain-Tanager and Crowned Chat-Tyrant, while we also heard Ocellated Tapaculos and Equatorial Antpittas. Unfortunately, the scarce Rufous-fronted Parakeets mostly eluded us, as we had a quick flyover in the fog and nothing more. The plant life in the páramo is surprisingly diverse and we encountered many interesting and showy species. Páramo Tapaculo Senecio formosus Barberry (Berberis sp.) Eccremocarpus viridis We left the cool temperatures of the high Andes behind and ventured northward along the Cauca Valley to the town of Jardín, our base for the next three nights. Situated on the eastern flank of the western Andes, the verdant, epiphyte-laden forest is one of the few strongholds of the endangered Yellow-eared Parrot. This species is an example of a conservation success story in Colombia. Mainly because of habitat restoration (including the regeneration of wax palms, its nesting tree) and an extensive education campaign, the numbers of this beautiful parrot have rebounded from just 81 known individuals in 1999 to around 2,600 individuals today. We were treated to great flyover views of at least 25 individuals; a welcome sight especially considering the previous low numbers of this species. We also succeeded with the endemic Chamí Antpitta as well as a Chestnut-naped Antpitta, while the meals that we were served by a local family at El Roble were some of the best of the trip! Chestnut-naped Antpitta Chamí Antpitta Yellow-eared Parrots Buff-tailed Coronet The town of Jardín is also home to two avian spectacles that have to be seen to be believed. For several decades, a lekking ground for the Andean Cock-of-the-Rock has persisted on the outskirts of town. Males strut their stuff, showcasing their slick dance moves and outrageous plumage for the more subdued females. She watches quietly from her perch, her discerning eye picking the male that is most fit to be the father of her future offspring. Watching this exhibition at arms-length was cited as a trip highlight for everyone. Andean Cock-of-the-Rock Moustached Puffbird The other spectacle that we were lucky to witness was a nesting area for the Oilbird. The Oilbird is one of the strangest bird species found in the Neotropics. Though superficially resembling a nightjar, they are in fact the only living member of the family Steatornithidae as well as the order Steaornithiformes. Oilbirds are unique in that they are a nocturnal frugivore, while they also use a primitive form of echolocation! Oilbirds roost somewhere secluded during the day, often deep in a cave or within an inaccessible gorge next to a flowing river, and at night they get to work. Oilbirds fly around in search of lipid-rich oil palms or tropical laurel fruits. They are well-adapted to this as they possess extremely large, sensitive eyes, while they also produce audible clicking sounds which act as a sort of echolocation. Their behaviour is more like a fruit bat than any bird. Oilbirds Oilbirds Crossing the river near Jardín, Antioquia, Colombia To see these Oilbirds, we embarked on a long walk deep into the gorge of a montane river, then crossed the river via a swinging bridge (while using a safety harness) to get to the site opposite the Oilbird nests. In case you were wondering, the nests are made entirely out of bird droppings. It was a privilege to spend some time near these unique birds! At this site we also enjoyed a very productive feeder setup that hosted several other endemic Colombian birds - the Red-bellied Grackle and Colombian Chachalaca. Red-bellied Grackle Green Jay Colombian Chachalaca On our final day of the tour we began with a morning of exploration in the dry forests next to the Cauca River near the town of Bolombolo. The species composition here was different, yet again. We had two main bird targets here, both being endemic species to this valley, including the Apical Flycatcher and Antioquia Wren. We succeeded with both while we also found Scarlet-fronted Parakeet, Moustached Puffbird, Black-striped Sparrow and Greyish Piculet, along with dozens of butterflies. Apical Flycatcher Cydno Longwing (Heliconius cydno) Before arriving at our hotel in Medellín for our farewell dinner, we had one final stop in store. La Romera National Reserve is one of the best places in the world to see the Colombian near-endemic Yellow-headed Manakin. It took a while but eventually we were all awarded with excellent views of this difficult species. Yellow-headed Manakin And in the final few minutes, as we were getting ready to leave, I finally found a snake for the group, an Equatorial Mussarana which was even a new species for yours truly. An excellent way to wrap up a hugely successful tour! Equatorial Mussurana (Clelia equatoriana) Equatorial Mussurana (Clelia equatoriana) My next post will document our tour extension to the Juan Solito Ecolodge in the northeast of the country.
February 27, 2024 The rains fell sometime after we went to bed and continued through the night, infiltrating our dreams. Light rain was still dripping from the trees as we awoke, and the dawn chorus was proportionally muted. We had a quick breakfast and by 6:30 were on the small trail system behind the lodge. The mosquitoes were ferocious, and repellent only temporarily thinned them out, providing just a brief reprieve for a few minutes. Birding was slow given the gloomy conditions but we tried our best to turn up a Blue-cheeked Jacamar or Rufous-necked Puffbird without success. Moises's only strategy was to loudly blast tapes of both species on repeat, so we weren't really surprised with the lack of a response. These types of tactics usually result in the target species being "taped out" in short order, and this is the main place at Muyuna Lodge where most birders try to find these respective species. However, we finally connected with a Varzea Thrush. The views were brief as it was skittish in the understory, but we heard it singing and calling and I managed a few recordings. We were also pleased to find a pair of Black-throated Antbirds. This species prefers dense understory growth, often near streams in the forest, and it is never easy to see well or photograph. I managed a few record shots of both the male and the female, representing the first meagre photos I have obtained of this species. If only my autofocus was working then I would have come away with much better results. Black-throated Antbird (male) - Muyuna Lodge, Loreto, Peru Black-throated Antbird (female) - Muyuna Lodge, Loreto, Peru Later, we tracked down a pair of Coppery Titi Monkeys (Plecturocebus cupreus) that were duetting at the edge of the forest. In Amazonia there are numerous species of titi monkeys, each separated by range. This species was a new one for us - they are only found in the western Amazon basin in Peru and western Brazil. Coppery Titi (Plecturocebus cupreus) - Muyuna Lodge, Loreto, Peru While the persistent rain may have made birding a little tough, there are certain other types of animals that thrive in these conditions. One particular group are the coral snakes. Laura and I have been fortunate over the years to have encountered numerous coral snakes - we are now up to seven species - but each encounter is never predictable and is to be cherished. Sometimes, heavy rains slightly increase the odds of encountering one. These snakes are typically fossorial, meaning that they spend much of their time living and hunting underground. Heavy rains may temporarily flood them out and bring them to the surface. All three of us noticed the snake around the same time. "Coral snake!" Evidently the night's rains had stimulated this one to leave its subterranean retreat. This was a subadult Western Ribbon Coralsnake (Micrurus helleri). It was quite feisty and tried to make a quick escape, though we cornered it on the trail so that we could study it for a few minutes. I managed a few poor phone photos in the dim understory, but its erratic movements and the low light levels meant that I was unable to take any good photos with my telephoto. Unfortunately, my macro lens was resting safely back in our room. Western Ribbon Coralsnake (Micrurus helleri) - Muyuna Lodge, Loreto, Peru Still, even without amazing photos we were ecstatic to have found a new species of coral snake for us! It made us forget about the hungry mosquitoes for a few minutes. Western Ribbon Coralsnake (Micrurus helleri) - Muyuna Lodge, Loreto, Peru Next up were these photogenic Cream-colored Woodpeckers near their nesting cavity. The diversity of colours found in Neotropical woodpeckers is high, and the Cream-colored is a flashy one. Cream-colored Woodpeckers - Muyuna Lodge, Loreto, Peru We also turned up this interesting little lizard. This is Cercosaurus argulus, the Elegent Eyed Lizard. This is a rarely seen semi-arboreal species, but we were fortunate in that this individual was foraging in the leaf litter. This is a shade-loving lizard that is rarely found in open sunny conditions. Elegant Eyed Lizard (Cercosaurus argulus) - Muyuna Lodge, Loreto, Peru Laura spotted this Blue-lipped Tree Lizard (Plica umbra) perched on top of a tree buttress. This species seems to be relatively common and easy to encounter; they are usually perched 1-2 meters off the ground and are somewhat conspicuous. Blue-lipped Tree Lizard (Plica umbra) - Muyuna Lodge, Loreto, Peru By mid-morning we returned to the lodge. The sun was now trying to burn through the thick clouds and bird activity was increasing. It was time to head out onto the water for a couple of hours before lunch time. We were still on the lookout for a few species - namely, the Purple-throated Cotinga - but secondary targets included Wing-barred Seedeater and Gray-chested Greenlet. We slowly cruised along the quiet waterways, scanning the tops of the lush vegetation for perched cotingas. Alas, we were unsuccessful with the primary target. However, luck was on our side with the other two species. We heard a singing Wing-barred Seedeater and while trying to to track it down, a Gray-chested Greenlet vocalized from the other side of the wetland! Quickly, both species were "in the bag". Wing-barred Seedeater - Muyuna Lodge, Loreto, Peru Wing-barred Seedeater - Muyuna Lodge, Loreto, Peru The Gray-chested Greenlet is a widespread species of Amazonia, usually living in flooded forest. It is more localized in the western part of its range which may explain why Laura and I had never seen one before. Gray-chested Greenlet - Muyuna Lodge, Loreto, Peru We headed back to the lodge, our spirits lifted after a productive boat trip. Laura and I were eager to continue exploring, especially since the morning's birding had been relatively slow with all the rain. Bird activity was still high even at midday as the clouds hadn't disappeared, but Moises was not at all eager to head back out. It took some convincing to have him relent and agree to a 2 PM departure time, instead of the usual 3 PM. The joys of having to be stuck with a guide, especially one who was just going through the motions. Riverside habitat - Muyuna Lodge, Loreto, Peru Our strategy this afternoon was similar to the pre-lunch boat trip. We would cruise slowly along vegetation-choked waterways, scanning the treetops for the cotinga. We had a brief moment of excitement when a female cotinga was found feeding in a fruiting tree. Alas, my terrible record photos confirmed that it was "just" a Plum-throated Cotinga. A great bird, but not the one we were hoping for! Plum-throated Cotinga (female) - Muyuna Lodge, Loreto, Peru Even without a Purple-throated Cotinga we really enjoyed our time on the water. Birding was relaxed and productive, with hardly a dull moment. We tallied nearly double-digit species of parrot-types, several Muscovy Ducks, many ant-things and woodcreepers by voice, and quite a few terns, kingfishers and other birds typical of these wetland habitats. There were several Brown-throated Three-toed Sloths (Bradypus variegatus), and we discovered a Horned Screamer nest, home to a couple of baby "screamlets". Brown-throated Three-toed Sloth (Bradypus variegatus) - Muyuna Lodge, Loreto, Peru Horned Screamers - Muyuna Lodge, Loreto, Peru As the sun set we tried listening for and playing tapes of Zigzag Heron to no avail. We cruised back to the lodge at dusk. Despite the slow morning, we had still managed to tally around 130 bird species. The diversity in the Amazon is amazing! Laura and I convinced Moises to head back out for a short boat cruise after dark. This time, we did not venture too far from the lodge, focusing on the frogs that were calling from thick vegetation along the edges of the channels. Pygmy Hatchet-faced Frog (Sphaenorhynchus carneus) - Muyuna Lodge, Loreto, Peru Pygmy Hatchet-faced Frogs were one of the dominant voices. This was a new species for us, presumably because they prefer these semi-aquatic, marshy habitats that are not easy to reach (while staying dry) except by boat. Pygmy Hatchet-faced Frog (Sphaenorhynchus carneus) - Muyuna Lodge, Loreto, Peru We also noted several Dendropsophus tree frogs in the riverside vegetation as well. Some were left unidentified, though some were likely Dendropsophus triangulum, the Variable Clown Treefrog. Dendropsophus sp. - Muyuna Lodge, Loreto, Peru Variable Clown Treefrog (Dendropsophus triangulum) - Muyuna Lodge, Loreto, Peru This particular individual appears to be Dendropsophus reticulatus, the Reticulated Treefrog. Reticulated Treefrog (Dendropsophus reticulatus) - Muyuna Lodge, Loreto, Peru Of course there was a lot of other things of interest to point our flashlights at, including various insects and spiders. Below are some of the others. It was a lot of fun to take photos with my macro lens as it had working autofocus - a nice change after struggling to manual-focus with my telephoto lens during the day. Ancylometes sp. - Muyuna Lodge, Loreto, Peru Stagmatoptera binotata - Muyuna Lodge, Loreto, Peru Polka-dot Treefrog (Boana punctata) - Muyuna Lodge, Loreto, Peru Unidentified planthopper - Muyuna Lodge, Loreto, Peru Alpaida sp. - Muyuna Lodge, Loreto, Peru Cuernavaca longula - Muyuna Lodge, Loreto, Peru Tetrataenia surinama - Muyuna Lodge, Loreto, Peru We returned to the lodge not quite feeling ready for bed just yet. It was only 9 PM and, as it was our last night in the Amazon, we wanted to make the most of things. Laura and I set off on a quick night-hike on the trail system. First up was a Southern Opossum (Didelphis marsupialis) that was lurking around some of the cabins. Southern Opossum (Didelphis marsupialis) - Muyuna Lodge, Loreto, Peru Next, we braved the mosquitoes on the trail system in search of herps. We couldn't turn up any snakes, but quite a few frogs cooperated. Most were this species, the Red-snouted Treefrog (Scinax ruber), a widespread species found throughout most of South America and locally in the Caribbean and Central America. Red-snouted Treefrog (Scinax ruber) - Muyuna Lodge, Loreto, Peru Red-snouted Treefrog (Scinax ruber) - Muyuna Lodge, Loreto, Peru Red-snouted Treefrog (Scinax ruber) - Muyuna Lodge, Loreto, Peru We also noted various Cane Toads (Rhinella marina) and Neotropical Grass Frogs (Leptodactylus sp.), as well as a few Sheep Frogs (Hamptophryne boliviana) that were calling from a flooded section. Cane Toad (Rhinella marina) - Muyuna Lodge, Loreto, Peru Leptodactylus sp. - Muyuna Lodge, Loreto, Peru Sheep Frog (Hamptophryne boliviana) - Muyuna Lodge, Loreto, Peru We spotted this Bridled Forest Gecko (Gonatodes humeralis) sleeping on some trailside vegetation, while a little further along was a gorgeous Yellow-banded Pinktoe Tarantula (Avicularia juruensis). Bridled Forest Gecko (Gonatodes humeralis) - Muyuna Lodge, Loreto, Peru Yellow-banded Pinktoe Tarantula (Avicularia juruensis) - Muyuna Lodge, Loreto, Peru Yellow-banded Pinktoe Tarantula (Avicularia juruensis) - Muyuna Lodge, Loreto, Peru As we were heading back to the lodge, my flashlight caught the eyeshine of a spiny rat in the genus Proechimys. These are some of the most abundant mammals in Amazonia (not including several bat species), but, because they are nocturnal, we haven't seen them too many times before. Proechimys sp. - Muyuna Lodge, Loreto, Peru February 28, 2024 Our final day at Muyuna Lodge. We were up early this morning and under clear skies we motored northward to the Amazon River. Our goal this morning was to attempt to find the last river island specialty we needed in this part of the Amazon, the River Tyrannulet. This species isn't as localized as some of the other species we had already seen along river islands, yet it was still a big hole on our lists that I was eager to fill. Luckily, it did not take us too long to find a pair of them. They came right in to playback, allowing us to have excellent views of them in the riverside vegetation. My photos leave much to be desired; they were moving too quickly for me to have much success at all with manual-focusing. River Tyrannulet - Muyuna Lodge, Loreto, Peru Moises also took us to his guaranteed site for Sand-colored Nighthawk, as our only view had been of one flying over the river at dusk back at the ExplorNapo Lodge. We quickly found a roosting nightjar and Moises happily proclaimed that we had found a Sand-colored Nighthawk. The only problem, of course, was that it was a Band-tailed Nightjar, which is a common riverside species that we have seen on numerous occasions over the years. Moises wasn't too happy with me challenging his identification, but that is indeed what the bird was. Alas, we were unable to find any real Sand-colored Nighthawks. Ladder-tailed Nightjar - Muyuna Lodge, Loreto, Peru Many birds were active along the main Amazon River. There were signs of the impending spring conditions in the northern hemisphere as well, as many dozens of Fork-tailed Flycatchers and Eastern Kingbirds were flocking together and heading upriver, alongside hundreds of migrant Barn and Bank Swallows. Eastern Kingbird - Muyuna Lodge, Loreto, Peru We returned to the lodge by 9:30 for a late breakfast. Laura and I still had a couple of hours remaining until our departure time and so we went for a final walk on the trails behind the lodge. Perhaps the sunny conditions would make it easier to find our remaining targets, the Blue-cheeked Jacamar and Rufous-necked Puffbird. Rutela lineola - Muyuna Lodge, Loreto, Peru Unidentified brush-footed butterfly (family Nymphalidae) - Muyuna Lodge, Loreto, Peru Bird activity was the best we had seen it on these trails and we even found a few mixed flocks to pick through. Butterflies and lizards were also active. Metamorpha elissa - Muyuna Lodge, Loreto, Peru Bridled Forest Gecko (Gonatodes humeralis) - Muyuna Lodge, Loreto, Peru Unidentified clearwing butterfly (tribe Ithomiini) - Muyuna Lodge, Loreto, Peru Agyrtidia uranophila - Muyuna Lodge, Loreto, Peru We returned to the lodge having had a very nice walk behind the trail system, even if the main target birds refused to cooperate. By the time we packed up and left Muyuna, our eBird checklist had reached 100 species for the morning. Despite the difficulties that we had working with Moises, we still had a really nice visit at Muyuna Lodge. Finding our main target (the Wattled Curassow) on the first morning was a mega highlight. Herps were plentiful and we finished with five species of snakes, including a lifer coral snake. We also found some really interesting lizards including several Northern Caiman Lizards, a species I have wanted to see ever since I was a herp-obsessed teenager. And birding by boat along mega-diverse waterways, with a light breeze cooling us down, was a nice change of pace from slogging it along muddy trails with high temperatures and humidity. Muyuna Lodge is very comfortable and the staff are friendly and accommodating, while the food was excellent. This is a beautiful corner of the world and I hope to return one day.
February 26, 2024 As dawn broke, Laura, Moises and I slowly cruised along a quiet watercourse. The dawn chorus was active and included species like Ferruginous Pygmy-Owl, Zimmer's Woodcreeper and Black-tailed Antbird, but I stayed focused on the treeline, hoping that a curassow-shaped bird would appear. The dawn chorus quieted as the sun rose above the horizon. Early morning is the best time to find the curassow, and we were running out of time. Domain of the Wattled Curassow - Muyuna Lodge, Loreto, Peru And there it was! It was the bright red bill that first caught my attention and 0.05 seconds later, my brain registered that I was staring at a female Wattled Curassow. Wattled Curassow - Muyuna Lodge, Loreto, Peru But it was better than I had imagined - the female was accompanied by a tiny chick! For a few magical minutes we watched the duo in their element. Wattled Curassow chick - Muyuna Lodge, Loreto, Peru Wattled Curassow chick - Muyuna Lodge, Loreto, Peru Wattled Curassows are closely associated with these rivers in the western Amazon basin and that has led to their downfall. The rivers are the highways, and curassows have a lot of meat. But in a few areas like here, hunting of the curassows does not occur and encounters with this secretive species are possible. The curassows like feeding on the fruits of mahogany trees that line the watercourses, and that is likely what this female was on the hunt for. Wattled Currasow - Muyuna Lodge, Loreto, Peru We were on cloud nine after such an epic start to the day! I was pleased that I even managed some mostly in-focus photos with my broken lens. For the next few hours we cruised around by boat, checking out different waterways in search of some of our target birds. We were successful with Black-tailed Antbird and Short-tailed Parrot. Black-tailed Antbird - Muyuna Lodge, Loreto, Peru Short-tailed Parrot - Muyuna Lodge, Loreto, Peru It was a very birdy morning and we cleared the hundred species mark before returning to the lodge for breakfast. Bluish-fronted Jacamar - Muyuna Lodge, Loreto, Peru Black-tailed Tityra - Muyuna Lodge, Loreto, Peru Proboscis Bat (Rhynchonycteris nasa) - Muyuna Lodge, Loreto, Peru After breakfast, we searched by boat for some of the few remaining target birds I had in mind such as Purple-throated Cotinga, Gray-eyed Greenlet and Wing-barred Seedeater, but were unsuccessful. Unidentified katydid - Muyuna Lodge, Loreto, Peru We were also on the lookout for Dusky-billed Parrotlets, a potential lifer for Laura and a new photographed bird for me. Moises claimed sightings on a few occasions, but each time my photos revealed that they were the more expected Riparian Parrotlets. Band-tailed Antbird - Muyuna Lodge, Loreto, Peru At one point during the afternoon we entered an area of higher ground where there was a small walking trail. After spending most of the day in a boat it felt great to feel the earth beneath our boots, even though this meant that we were accompanied by a swarm of mosquitoes. Amazonian Trogon - Muyuna Lodge, Loreto, Peru Methona confusa - Muyuna Lodge, Loreto, Peru We found several groups of Eastern Pygmy Marmosets, one of the smallest species of monkey! Eastern Pygmy Marmoset (Cebuella niveiventris) - Muyuna Lodge, Loreto, Peru Eastern Pygmy Marmoset (Cebuella niveiventris) - Muyuna Lodge, Loreto, Peru Our guide, Moises had a stake-out for Nancy Ma's Night-Monkey (Aotus nancymai) that was visible from the main watercourse. Nancy Ma's Night-Monkey (Aotus nancymai) - Muyuna Lodge, Loreto, Peru During the mid-afternoon, Moises took us down a channel choked with vegetation to look for some herps. We kept a close eye on the vegetation until Laura spotted the first snake, as she is known to do! Giant Parrot Snake (Leptophis ahaetulla nigromarginatus) - Muyuna Lodge, Loreto, Peru While we have seen this widespread species before, this was a new subspecies for us. The extensive black markings between the scales are quite distinctive. Giant Parrot Snake (Leptophis ahaetulla nigromarginatus) - Muyuna Lodge, Loreto, Peru Even better than the parrot snake was this next species: a Northern Caiman Lizard (Dracaena guianensis)! I have wanted to see this huge species of lizard for many years but had never gotten lucky. As the name suggests, particularly large individuals somewhat resemble caimans, and they share similar aquatic habitats. Caiman lizards feed on snails, fish, amphibians and other creatures that they find underwater. Northern Caiman Lizard (Dracaena guianensis) - Muyuna Lodge, Loreto, Peru Northern Caiman Lizard (Dracaena guianensis) - Muyuna Lodge, Loreto, Peru As the sun set, we found ourselves slowly paddling in a different wetland after another unsuccessful Purple-throated Cotinga search. We enjoyed watching a pair of Yellow-chinned Spinetails. This species is widespread in South America but is fairly localized in Peru. Yellow-chinned Spinetail - Muyuna Lodge, Loreto, Peru You would be hard-pressed to find an activity that Laura likes more than a night-hike in the tropics, and tonight's walk was a good one. We only stayed out for a short while but came away with some nice sightings, including several snakes! Smoky Jungle Frog (Leptodactylus pentadactylus) - Muyuna Lodge, Loreto, Peru Ancylometes sp. - Muyuna Lodge, Loreto, Peru Unidentified net-casting spider (family Deinopidae) - Muyuna Lodge, Loreto, Peru Crowned False Boa (Pseudoboa coronata) - Muyuna Lodge, Loreto, Peru Pierella hortona - Muyuna Lodge, Loreto, Peru Leptodactylus sp. - Muyuna Lodge, Loreto, Peru Sais rosalia - Muyuna Lodge, Loreto, Peru Garden Tree Boa (Corallus hortulana) - Muyuna Lodge, Loreto, Peru I think my favourite sighting of the walk was this Slender Opossum (Marmosops sp.). It was extremely confiding and didn't mind my close approach for photos. Slender Opossum (Marmoseps sp.) - Muyuna Lodge, Loreto, Peru Though they may resemble a rodent to some (Moises confidently identified it as an "Amazonian Mouse", whatever that is), these are actually a tiny genus of neotropical opossums, meaning that they are a marsupial. Slender opossums typically live in the viny, dense understory where they search for insects, arachnids, flowers and fruit. Slender Opossum (Marmoseps sp.) - Muyuna Lodge, Loreto, Peru My final post from Peru will include our last couple of days at Muyuna Lodge.
