And it  looks like city birds also sing differently than their country cousins.  In the July 17 <em>Nature,<\/em> Hans Slabbekoorn and Margriet Peet  of Leiden  University in the Netherlands report that urban great tits generally  sing higher notes than rural great tits. (For any snickering  12-year-old, a great tit is a bird common in Europe that looks a little  like a black-capped chickadee.) The birds do so, say the researchers, to  make sure that their mating songs are heard above the low-frequency  noise pollution of planes, automobiles, and other urban racket. Great  tits in quieter locales, in contrast, sing more low-frequency notes. The  researchers write: &#8220;Our findings show, to our knowledge for the first  time, that human-altered environments might change the communication  signals of a wild bird species.&#8221; They also worry that bird species that  can&#8217;t adjust their songs to human noise may suffer breeding declines. <\/span><\/p>\n<h6><em>This news brief appeared in the Random Data column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 7\/22\/2003.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>It&#8217;s a cliche that people who live in large cities generally talk faster and louder than their rural counterparts.
