Birds

For captive animals, engaging in natural behavior is a pillar of the animal welfare framework. But when it comes to sex, one important behavior has been largely ignored, and sometimes even punished: masturbation.

Exactly how birds follow invisible maps around the globe has long eluded scientists – but in a first, scientists have discovered some surprising biological processes taking place inside pigeons that could change how we look at animal navigation.

Texas-based company says its artificial egg supports the full development of bird embryos outside a biological eggshell, without requiring supplemental oxygen. The work is part of its plan to “de-extinct” birds, including the giant moa and dodo.

One of the world’s most dangerous birds may carry signals invisible to the human eye. Scientists have found that the helmet-like casque atop a cassowary’s head fluoresces under UV light, revealing striking patterns that differ between species.

Parrot feathers found at a thousand-year-old burial tomb in Peru provide new evidence for an expansive live bird trade network across the Andes Mountains that pre-dates the Inca Empire, a new study suggests.

When COVID-19 lockdowns emptied city streets, urban environments changed almost overnight. New research suggests that Los Angeles city birds responded just as quickly, with measurable shifts in beak shape in offspring born during the lockdown period.

It's that time of year – and my personal favorite corner of science to look back on – when we recap the many fascinating discoveries in the plant and animal kingdom in 2025. Orcas have again made news, but no luxury yachts were hurt in the process.

The extent of an incredible dinosaur highway has been revealed in Bolivia. More than 16,000 footprints, along with tail impressions, have been fully documented – and the scale of theropod activity alone is unlike anything that's been seen before.

Avian influenza viruses have a gene that makes them incredibly resistant to heat, rendering our body's natural defense system – fever – powerless in fighting infection. In fact, higher temperatures actually help those bird-derived bugs replicate.

You won't find us endorsing aggression towards animals very often, however, scientists have discovered that raising your voice to seagulls – especially if you're male – will make them think twice about stealing your food. It's simply science.

Don't be fooled by that soft-looking down and pretty faces – woodpeckers are tough, tree-pounding beasts who simultaneous harden their whole bodies like a hammer and grunt as they drill away with force of up to 30 times their weight.

Right now, groups of Icelanders are taking to the streets late at night, armed with cardboard boxes and torches, in search of the white bellies of baby puffins. This annual tradition has become one of the most fascinating rescue missions on the planet.
