A notable feature of recent days has been the presence of finches. House Finches, which have been in short supply (due largely, I believe, to a crippling eye disease), seem to be making a comeback; at any rate, they have become regulars at the edge of the woods and I have been hearing both their songs and calls. Also, a male Goldfinch has been circling the marsh on what I would have to call a Call Flight and not a Song Flight; as he flies round and round, he calls Per-chick-a-ree, Per-chick-a-ree over and over. The breeding biology of these birds is quite mysterious. They don't seem to be very territorial and they pair up and breed much later than other birds. Their extensive singing in the late winter and spring -- often in choral form -- does not seem directly related to mating activity. Some of the male's songs early in the year are among the longest and most elaborate songs that we hear but their meaning and purpose is obscure. Goldfinches are said to nest later than other species because they time their nesting to coincide with the appearance of thistle seeds (but in our case, they are feeding on Graundsel which has thistle-like seeds). If they are indeed just entering family life right now, perhaps the male's circular sumer Per-chick-a-ree flight, rather than its spring song, is connected with its breeding behavior. Perhaps.
