Does staying cooped up inside with your kids sometimes drive you up the wall? Take comfort in the bird that does it year after year — the hornbill. Each breeding season, a female hornbill plasters herself into her nest cavity, leaving only a thin slot for ventilation and food. She stays…

Most baby birds are adorable little floofs — but not all of them. The tongue and palate of estrildid finch chicks are strangely spotted and ringed. They display these markings while they beg for food. Most species’ chicks have mouth markings in colors ranging from black or white to bright…

Aunque suene extraño, la tierra ayuda a las aves a mantenerse limpias. Aves de todos los tamaños suelen rascar una depresión en el suelo y echarse polvo encima, para luego agitarse con energía y desprenderlo. Experimentos han demostrado que usan el polvo para evitar la acumulación de…

It might sound strange, but dirt helps birds scrub themselves clean. Birds of all sizes, like the Eurasian Skylark pictured here, often scrape a depression in the ground and flick dirt onto their bodies, shimmying to shake it off. Experiments showed that birds use dust to prevent oils from…

A pair of Bald Eagles will reuse their nest each year and repair it with new tree branches. But recently in British Columbia, scientists came across an eagle nest made largely out of dried kelp. Back in the ‘90s, that very nest had been made out of tree branches. What changed? Sea Otters…

In the depths of winter, when open water is frozen over, it can be challenging for birds to stay hydrated. Some birds eat the frozen water all around them. Cedar Waxwings catch snowflakes in mid-air. Black-capped Chickadees drink from dripping icicles. Plenty of other birds scoop up fresh…

There are five million bird eggs stowed away in museums across the world — and the study of eggs, called oology, can give us great insight into birds. The link between DDT and the decline of Peregrine Falcon populations was identified in part using museum and personal egg collections, and…

The Eurasian Hoopoe isn’t picky about where it nests. But whether it builds a home in a tree cavity, termite mound, or nest box, it’ll be stinky. Mother birds coat their eggs in an antimicrobial secretion that smells like rotten eggs. Then, when the chicks are hatched, they paint the nest…

Acorn Woodpeckers live in family groups of up to 15 individuals. Over time, if enough birds die off, an opportunity arises for unrelated birds to join the group and obtain a mate. Then, battles known as “power struggles” begin. Birds from other family groups form coalitions, with up to 30…

In the late 19 th and early 20 th centuries, the human fascination with bird feathers went a little too far. Women’s hats and dresses featured extravagant feathers from birds both near and far. The trade in feathers drove several species, from the Little Egret to the Great Crested Grebe…
