I've had several pine siskins at my window feeder n Mountlake Terrace. They have been very assertive --sometimes aggressive. They flap their wings at other birds, including somewhat larger species. And the other birds of different sizes (including juncos, chickadees, red breasted nuthatches, a Townsend's warbler, & house finches), leave right away. The siskins rule the roost.
