Yes, I have one of those, too. A Myrtle. Persistent aggressive behavior for the past 6 weeks at least, although the Bushtits are able to overwhelm it with superior forces.

About 5 days ago he started vigorously defending the suet feeder from other birds, particularly the Juncos and chickadees. We have had Yellow-Rumped warblers during the winter for several winters but this is the first time I have seen this behavior. Have others observed this behavior? Prior to this winter we were in another house with a very bird-friendly yard. I am wondering if part of the reason for this behavior is the relatively scarcity of food sources in this neighborhood.
