(PhysOrg.com) -- The Great Tit is an aggressive songbird found in Britain, continental Europe, parts of Northern Africa, and much of Asia. It is believed to survive mostly on seeds, nuts, fruit, insects, beetles, and spiders, but scientists studying a cave in Hungary have now discovered a population of Great Tits that kill and eat hibernating bats. http://www.physorg.com/news171788817.html Biology Thu, 10 Sep 2009 10:10:02 EST news171788817 (PhysOrg.com) -- A gene previously associated with physical traits is also dictating behaviour in a tiny fish widely regarded as a living model of Darwin's natural selection theory, according to a University of British Columbia study. http://www.physorg.com/news168674581.html Biology Wed, 05 Aug 2009 07:03:47 EST news168674581 Many whale species have sonar systems that send out two pings at once, allowing them to detect underwater objects with greater accuracy than even the most sophisticated human technologies, according to a study released Wednesday. http://www.physorg.com/news155385384.html Biology Wed, 04 Mar 2009 10:37:02 EST news155385384 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 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 communication. The findings contribute to the current understanding of how animals use signals to communicate. http://www.physorg.com/news150726143.html Biology Fri, 09 Jan 2009 12:22:23 EST news150726143
