EEvery summer, thousands of swamp sparrows (沼泽麻雀） sing songs in theNorth America's wetlands. These special brown birds only know a few songs, butthey sing them very well. In fact, their song list hasn't changed much forhundreds of years.Like humans, baby swamp sparrows learn songs from their elders. "Swamp sparrows justmake few mistakes when they learn their songs." says biologist Robert Lachlan. Actually, theycopy the music so well that it stays the same from the elder to the young."Just like children, the sparrows don't remember every song they hear, " Lachlan says. "They just pick up the songs they hear most often. It's an example of what scientists call‘conformist bias'." Until recently, this learning ability was thought to be special only tohumans.Between 2008 and 2009, Lachlan's team recorded the songs of 615 swamp sparrows acrossthe northeastern United States. The study found that only 2% of these sparrows sang a differentsong, while the other sparrows sang songs just from their list. "The song-types that you hear inthe wetland of North America today may have been there 1,000 years ago. " says Lachlan.However, another team found that a few sparrows changed their song list in recent years.Now scientists are exploring the influence of losing habitat (栖息地） on song birds. Man-madebarriers —— such as cities, roads and plantations —— can break up a bird population into a numberof isolated (孤立的） groups. It stops birds from sharing their songs with each other."The findings are really exciting. " says scientist Andrew Farnsworth. He hopes that futureresearch will start from these studies. For example, scientists might learn how other animalskeep their cultural traditions alive. Farnsworth adds, "It's really cool to think this could happento other animals too. "69.
