The White-crowned Sparrow loves to sound off in the springtime. Several YouTube videos of their breeding season concerts are on this blog. Who knew that they also whistle a tune in the winter? A passing mention in the Cornell bird lab website suggests that females may do some singing in the winter to claim their feeding territories. Males and females look so much alike that I can’t verify whether that applies here. In any case, this adult bird perched high up in a Torrey Pine in the DAWN area of the park in the afternoon of an early November day and held forth with this whistle. I could not be sure but I thought that at one point I heard a similar song in response at some distance.
