Researchers Show Invasive Sparrows Immune Cells Sharpen As They Spread
2013-11-20 13:39:25

University of South Florida Scientists unlock mysteries of invasive species by studying English sparrows which have spread to Kenya. When invasive species move into new areas, they often lose their natural enemies, including the microbes that make them sick. But new research from evolutionary biologists at the University of South Florida has found that adjustments in the immune system may help house sparrows, one of the world’s most common bird species, thrive in new areas. In...

Aggressive Sparrows Escalate Their Territorial Threats
2013-02-13 10:39:27

Alan McStravick for redOrbit.com - Your Universe Online A new study out of the University of Washington (UW) seems to build on a previous study reported on here at redOrbit only last month. The previous study, out of Duke University, relied upon a robotic ℠Frankensparrow´ to monitor sparrow behavior leading up to and during territorial brawls. The UW team wanted to learn about the threat signals given off by the defensive sparrow to a potential invader. As it turns out, song...

Robotic Swamp Sparrow Helps Understand Bird Aggression
2013-01-29 18:51:58

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...

House Sparrows Threatened By Urban Noise
2012-07-13 10:56:05

Lawrence LeBlond for redOrbit.com - Your Universe Online Man-made noise is something that will likely never go away, yet, long-term exposure to the commotions of everyday hubbub is increasing the likelihood of many health issues for us humans. But humans aside, the ever-droning din of our everyday cultures are also taking a toll on birds, particularly house sparrows. In the United Kingdom, the house sparrow population has been in decline since the 1970s, and noise pollution could be...

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...

Younger Birds Get No Respect
2012-02-09 04:01:34

When mature male white-crowned sparrows duel to win a mate or a nesting territory, a young bird just doesn't get much respect. Researchers found that older male white-crowned sparrows don't put much of a fight when they hear a young male singing in their territory — probably because the older bird doesn't consider the young rival much of a threat. But a male sparrow will act much more aggressively if it hears a bird of the same age singing in a territory it claims as its own....

While singing the same songs as your neighbors may sound harmonious, research conducted at Queen's University Biological Station (QUBS) suggests that song-sharing amongst song sparrow populations is actually an aggressive behavior, akin to flinging insults back and forth. "It's been hypothesized that repertoire size and song complexity is about the singer's ability to advertise their quality as a mate," says lead author Janet Lapierre, a visiting biologist from the University of Western...

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...

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...
