Pine Siskin

Erika and I are finding huge flocks of Pine Siskins. This year is a “finch year,” with siskins and other northern birds spreading across the United States. These irruptions are presumably tied to food cycles—during low food years birds move south. We have seen flocks of well over 100 birds swirling over our path. In this case, siskins were dripping from the limbs of an alder. Curiously, just in the last week have siskins discovered our home bird-feeders. So far only about a half dozen have appeared but the may be harbingers of bad news for our seed budget. It may be noteworthy that the siskins we’ve banded were emaciated. These birds are clearly hungry.
