Pine Siskin

Although not daily, a small flock of Pine Siskins has become regular at our feeders. Years ago in South Dakota, siskins were among my most banded birds. Even then, individual banded birds visited my feeders only irregularly. This cycle led me to hypothesize that groups of siskins roamed about town, perhaps trying to keep one step ahead of various predators such as hawks or shrikes.
