Ill-tempered warbler day

[Milton Trimitsis]

This morning I was watching a female common yellowthroat perched near a song sparrow when the warbler started to peck at the sparrow, driving it off the perch.  And then this afternoon, I saw 2 black-and-white warblers seeming to harass 2 cedar waxwings.  The BAWWs kept driving the waxwings off their perches and dive-bombing them in the air.  The first interaction happened in a cherry tree along my driveway, and the second in the power line right-of-way nearby.  All of this was new behavior to me — was there some announcement I missed?

Cheers,
