The study shows that bird mothers can adjust egg size depending on their social conditions. This counters the idea that, with more help, mothers lay smaller eggs.
It’s hard work saving birds from extinction, but we have the evidence of successful interventions to show we can avoid further losses.
Birds have one unchanging scientific name, but often many common names that are subject to change. Choosing a new name for a bird isn’t necessarily a simple decision.
Climate change could reduce suitable nesting sites for the wandering albatross on Marion Island.
The Agulhas long-billed lark builds nests on the ground in endangered fynbos vegetation. Here’s how it is surviving.
Researchers have made a fascinating observation: a polar bear used a diving hunting technique, never before reported, to capture large moulting snow geese.
These tiny songbirds have extraordinary memories for the tens of thousands of spots where they hide food. But that doesn’t help when heavy snow blocks their access.
North American ornithologists are seeking to replace all bird species named after people - but what should they be called instead?
A deadly strain of bird flu is circulating in animals. So far the virus has been detected in seabirds on islands near Antarctica. What does this mean for wildlife, tourism and research?
H.B. Tristram was a Victorian clergyman and ornithologist who categorised a list of birds he’d found in Palestine.
Migrating birds need stopover locations en route where they can rest and feed. A new study shows that artificial light draws them away from sites they would normally use and into risky zones.
Research shows providing food for birds not only stops them going hungry, it may help them fight off infection too.
What’s in a name? A lot, if you’re an Audubon’s Oriole or a Townsend’s Solitaire.
Researchers used ‘citizen science’ birdwatching data to rank Australian species. Among the most elusive birds were ‘hide and seek’ champions and a few possibly headed for extinction.
From dark dragonflies becoming paler to plants flowering earlier, some species are slowly evolving with the climate. Evolutionary biologists explain why few will evolve fast enough.
Our birds are tough. They went through some mean climatic conditions to make Australia home.
Birds’ nest-building skills are informed by their environment and experiences, and nests can reflect the individual styles of their builders.
Only after a species is identified and listed by taxonomists can it be protected. Yet we still don’t have one globally agreed-upon list of every species. A new 74-nation survey points to the solution.
246 scientists looked at the same data sets and drew very different conclusions.
New research looks at how different species have managed to cross geographic barriers throughout history and whether their individual traits played a crucial role in these journeys.
