Lee Rannals for redOrbit.com — Your Universe Online A new study has found male sparrows actually perform a little trash talk before engaging in a brawl to the death. Researchers wrote in the journal Behavioral Ecology and Sociobiology male swamp sparrows use wing waves as an aggressive signal to defend their territories and warn away intruding males. "For birds, wing waves are like flipping the bird or saying 'put up your dukes. I'm ready to fight,'" Duke University biologist...

iPod owners aren't the only ones who frequently shuffle their favorite tunes. Baby songbirds do it, too, a new study shows. A baby songbird prefers to learn the clearest versions of songs he hears and uses them to build his personal playlist for life. As a result, noise, from nature and humans, influences which songs a bird learns to sing and can create lasting changes to his species' top tunes, the study's results suggest. "There's been an enormous amount of interest in how...

It may take a village to raise a child, and apparently it takes at least two adult birds to teach a young song sparrow how and what to sing. In the first study conducted in the field to examine how juvenile song birds learn their repertoire, University of Washington researchers have learned that eavesdropping on the singing conversations between two adult sparrows appears to be a key event in song learning. The results are being published Oct. 21 in the online edition of the Proceedings of...

Songbirds such as swamp sparrows appear to sing sophisticated, hard-to-produce songs in hostile situations, a U.S. university researcher said. When challenged, male swamp sparrows escalate their vocal performance by increasing the frequency range and speed of their songs, a study by University of Miami biology graduate student Adrienne DuBois said. The findings add to researchers' understanding of how birds use signals to communicate, DuBois and her colleagues said. Vocal performance was...

Birdsongs are used extensively as models for animal signaling and human speech, offering a glimpse of how our own communicating abilities developed. A new study by Adrienne DuBois, a graduate student at the University of Miami (UM) College of Arts and Sciences Department of Biology, shows that the Swamp Sparrow has the ability to emit songs that are physically difficult to produce during hostile situations, implying that songbirds use sophisticated vocal performances as signals in aggressive...
