Aggression

This ruby-crowned kinglet literally jumped on the Tennessee warbler in the pond.


It may have been territorial or perhaps a misguided attempt to breed.
Either way the Tennessee wasn't amused.
I've not seen behaviour like this before.
The more you watch the more you see.

There is a yellow rumped warbler in the foreground.
