The males somehow know who among them is dominant and the distribution of the various singers is simply a reflection of,this.
Unmated males are the most vociferous of all the singers, but even mated males sing throughout the breeding season in defense of their territories and in hopes of attracting additional mates.
Up to 5 percent of male chipping sparrows have what it takes to be what all males want to be—polygynous.
But females, who do most of the parenting later on, are careful and choosy, mating with previously mated males only when the territory is large and resources are plentiful.
It’s interesting that males seldom have neighbors with the same song, especially since they originally learned songs from their neighbors. Kroodsma suggests this is simply a consequence of a huge turnover in the sparrow population, perhaps as much as 50 percent every year.
All the more reason to be the best you can be this breeding season.
