Thisrollicking song belongs to a Black-headed Grosbeak. Like most birds, the malegrosbeak begins singing in earnest a few days after reaching his traditionalnesting grounds in spring. And,like most birds, he sings frequently when trying to attract a mate. He’ll singa bit less while he and his mate incubate eggs, but pick up the pace againafter the young hatch. By late summer, his singing will cease. Everwonder how much a bird sings in one day? Some patient observers have shown thata typical songbird belts out its song between 1,000 and 2,500 times per day.Even though most bird songs last only a few seconds, that’s a lot of warbling! Onnights with a full moon, male Sage Thrashers have been known to proclaim theirlong-winded songs all night. But the North American record-holder may well bethe Red-eyed Vireo. One such vireo delivered its short song over 22,000 timesin ten hours!
