Birds adapt their sounds based on habitat, latitude, and size, with smaller birds using wide frequency ranges to ensure survival.

Now the next step: evolution. The Grants found that the offspring of the birds that survived the 1977 drought tended to be larger, with bigger beaks. So the adaptation to a changed environment led ...

Researchers at the University of Wisconsin–Madison have conducted the first-ever global study of the factors that influence bird sounds, using more than 100,000 audio recordings from around the world.

The toothless beak, large eye sockets ... led the researchers to compare it to a “Rosetta Stone” of bird evolution. “Just ...

Our two pieces of recent research identified that, in response to warming, more than 100 species of Australian birds have developed smaller bodies and bigger beaks over time. When we talk about ...

Over time, natural selection favored finches with sharper, longer beaks. These birds were better equipped to quickly and easily pierce the skin of their booby bird neighbors. Vampire finches still ...

“What we found was there was the slow, steady kind of gradual evolution,” says Steve. Many of the features that we think of when we think of birds – feathers, wings, wishbones, and beaks ...

Irrespective of directionality, beak saturation also related to beta diversity, indicating that birds with more similar beak coloration profiles had more similar microbiome community structures.

Prior work on these birds had established that birds' beaks ... then song changes related to beak evolution could perhaps catalyze ecological speciation." But, at the time, Podos had no smoking ...
