aggressive sparrow action
- I live in town in Fort Bragg and I am watching birds more closely
than before since this is the first year I've been involved in
Project Feeder Watch. I'm wondering if what I have now seen 3 times
is unusual or common. I have seen both White Crowned and Golden
Crowned Sparrows feeding at a platform feeder with Pine Siskins. Both
species have grabbed a Siskin by a wing tip, twirl it around almost
360 degrees and let it go.
I'm curious if this is something I've just missed before; how common is this?
