Tropical songbirds have a lower adult mortality rate than temperate birds because they are raised in smaller families. This directly affects their wing growth and ability to escape from predators.
A lab at University of California, San Francisco has made new learnings regarding the brain-path reasons why songbirds sometimes mix it up musically and other times sing by rote.
Anyone who has lived in New York can tell you that city life doesn't exactly make you friendly. In fact, you can grow to be downright suspicious of strangers if you live in the wrong neighborhood. Now, a new study has found that the same is true for birds, with urban sparrows proving far more aggressive and unruly, compared to their rural relatives.
For nightingales, nothing is hotter than good fathering skills. That's at least what bird experts now think after extensively studying the songs of male nightingales. Traditionally, it was thought that these songs simply told listening females about a male's health and other desirable traits. Now, they think the 'lyrics' are actually about how good a dad he'd be.
We all know that it's hard to keep up appearances when you're constantly on the go. That's why the fashion police will probably give some female warblers a free pass, even after researchers found that they boast drabber feather when their migration routes are particularly long.
As things stand, the United Kingdom does not have a national bird. That's what ornithologist David Lindo, who calls himself the "Urban Birder," wants to change. Ten birds have made a final short-list, and the Birder is asking the general public to vote which they think should represent their country.
Researchers have recently discovered that the same genes that help drive the development of human speech also play an important role in the brains of many songbirds - namely those with complex and beautiful songs.
Birdsong has long been compared to human music due to how pleasing it is to the ear. However, compared to the complex rules and theory behind human melody, birds are just children banging on pianos in the right way. Now, for the first time, one species of bird has been found to be following the complex rules of human music theory to a T.
A remarkably rare and threatened North American songbird appears to have found a new home in an unlikely place: the sprawling "biological deserts" of commercial pine farms. Conservationists had been concerned that the Swainson's warbler would ever boast a stable and unthreatened population. Now, with this new discovery, things are looking positive for the first time in decades.
More than 360 different songbird species are unique to the Eastern Himalayas, most of which cannot be found anywhere else on Earth. A new study details how exactly this came to be, and why the region's impressive avian diversity makes it an exceptionally important habitat for study.
Millions of tiny songbirds - weighing in at less than an ounce - migrate thousands of miles from the US to Central and South America each year on the coattails of nature's wind patterns, according to a new paper published in Journal of Biogeography.
