I find it amazing that, when they depart on autumn migration, juvenile waders can be faced with a journey of hundreds or thousands of kilometres. In the latest phase of their Oystercatcher studies in Iceland, Verónica Méndez and colleagues have been tagging young birds, just at the point that they can fly, to try to … Continue reading A young Oystercatcher’s first adventure
There is something pleasing about four wader eggs in a nest. They seem to fit so neatly, with their pointed ends in the middle, as illiustrated in the Ringed Plover nest alongside. There has been an assumption that this is an optimum arrangement for incubation, with strong selection to lay a maximum of four eggs. … Continue reading Four eggs or five?
A 2026 paper in Animal Behaviour examines how quickly juvenile Black-tailed Godwits(right, with juvenile Redshanks) acquire the feeding skills they will need to get them through their first winter. Josh Nightingale followed the same migration route taken by young birds, as they travelled south from Iceland, and measured their intake rates. How long did it … Continue reading Learning from their elders
The lowlands of Iceland are changing. Low-intensity farming is becoming economically challenging and marginal grazing land is increasingly being used for forestry, to provide summer cottages for city-dwelling Icelanders, for electricity generation and to expand tourist infrastructure. All of these developments require increased access to semi-natural areas with internationally important populations of ground-nesting birds. How … Continue reading Roads too! Another problem for Iceland’s waders
Autumn moult is an important part of the annual cycle of migratory shorebirds, typically squeezed in between chick-rearing and the onset of winter. The process of changing an individual’s feathers lasts as long as the whole of the breeding season but is far well less well studied. If a bird starts moulting too late or … Continue reading Moult, captured on camera

Researchers created a dataset of photos of thousands of paper-thin slices of a male and female cadaver to create one of the most detailed datasets about the human body.
In a remote corner of the driest state in the country, Anne Heggli's team has been keeping watch over some of Earth’s oldest beings. Since 02012, Heggli’s NevCAN network has recorded conditions at the Nevada Bristlecone Preserve every eight minutes. The result is more than 120 million data points and a high-resolution portrait of how a bristlecone pine thrives. Paleoclimatologist Adam Csank showed how bristlecone microcores reveal the droughts and floods these trees survived long before us, a history that fine-tunes models of what's ahead. Artist and philosopher Jonathon Keats went further. “The most accurate clock,” he said, “is a tree.” His monumental artwork Centuries of the Bristlecone keeps bristlecone time, a clock calibrated to the trees' own growth over millennia. Together, Heggli, Keats and Csank made the case for long science: patient, continuous observation that will help us answer future urgent questions. “Data at this resolution,” Csank said, “is like a Rosetta Stone” for understanding nature’s resilience. At fourteen years young, the bristlecone record is just beginning, Heggli said, but it already holds the key to questions like these: How will bristlecones adapt? What happens when the droughts and floods they've weathered for millennia arrive faster and more frequently? “We can't answer the questions if we're not watching,” said Csank. “We are the stewards of this data,” Heggli concluded. “This is why we need long science.”
