If you’ve ever been woken up before sunrise by the trilling and chirping of birds outside your window, you may have wondered: why do birds sing so loud, so early in the morning?<\/p>\n

\n <\/section>\n

Researchers at Duke University say there may be a good reason why birds are most vocal at first light. By singing early and often, a new study suggests, birds perform better during the day.<\/p>\n

The morning cacophony is mostly males, whose songs are meant to impress potential mates and rivals.
\n“It’s like they’re warming up backstage, before the sun comes up and the curtain rises,” said co-author Stephen Nowicki, a biology professor at Duke.
\nScientists have proposed various hypotheses for why birds do their most vigorous singing in the early morning hours. One idea is that it’s the best time to broadcast, since there’s little wind to distort their sound. Others have suggested that the dim light makes it difficult to do much else, like hunt for insects.
\nBut a study in the journal Animal Behaviour<\/i> points to another benefit: the early morning vocal warm-up works wonders for their singing.
\nTo test the “warm-up hypothesis,” Nowicki and Duke biologist Susan Peters recorded 11 male swamp sparrows between 2 a.m. and noon for two to three mornings each.
\nThe song of the swamp sparrow is a simple trill of up to five notes, repeated around 5 to 10 times a second. “It sounds a bit like a melodious police whistle,” Nowicki said.<\/p>\n
