Birds

Some birds make beautiful chirps and tweets. But the white bellbird blasts an obnoxious “song” so loud that it sounds almost digital. Now, researchers have measured just how ear-splitting it is – and crowned it the loudest bird call ever recorded.

Researchers from UT Southwestern implanted “memories” into the brains of zebra finches, teaching them to sing a song they’ve never actually heard.

A new study suggests that the total number of North American birds has declined by 29 percent since 1970.

Palaeontologists in New Zealand have now uncovered the remains of Heracles inexpectatus, an extinct giant parrot that would have stood hip-high to most people and packed a beak powerful enough to crack open pretty much whatever it wanted to.

Many animals adjust to changes in climate by shifting behaviors such as hibernation, reproduction and migration in order to optimize the continuation of the species. Unfortunately, a recent meta analysis of over 10,000 studies suggests these adaptations simply aren't happening quickly enough.

2019 marks the 10th year of the Audubon Photography Awards, and the introduction of two new prizes – the Plants for Birds Prize and the Fisher Prize. From over 8,000 entries from all over North America, the judges were tasked with choosing just six winners and four honorable mentions.

We know baby birds communicate, often loudly, and mostly about food, but a new study suggests they can also communicate with each other while still in the egg. This method of communication influences the behavioral and physiological traits of newly-hatched chicks from the same clutch of eggs.

An expedition to the “Lost City of the Monkey God” in Honduras has revealed a trove of natural treasures. The pristine forests house an incredibly rich ecosystem, including species new to science, some unknown in the area, some that haven’t been seen in decades and others that were believed extinct.

Generally speaking, the animals alive today are mere shadows of their former selves, and birds were no exception. In a Crimean cave, palaeontologists have uncovered the bones of some of the most gigantic birds to have ever walked the Earth, that would have lived alongside early European humans.

Birds flying together in formation can save substantial amounts of energy. But what’s good for the goose isn’t necessarily good for the gander, with scientists finding that for pairs of homing pigeons this approach actually costs them energy instead.

The hummingbird's ability to hover and make sharp turns could teach drones a thing or two. Now researchers at Purdue University have managed to do just that, building a hummingbird-inspired drone and teaching it to fly using algorithms trained on the birds’ natural flight patterns.

Evolution helps life adapt to new environments – and now scientists have uncovered a rare occasion where it got a second chance. About 136,000 years ago, a flightless bird on an island in the Indian Ocean was wiped out, only to re-evolve itself back into existence tens of thousands of years later.
