I have been watching hummingbirds in an attempt to get pictures of the female Black-chinned and the female Calliope. It has been unsuccessful so far. However, I did spot an unusual feature on a Black-chinned male: evidence of a battle.
I had long been aware that the Rufous Hummingbird was combative during the breeding season when it would challenge other rufous males. But, nothing was ever said about the black-chinned. Well, here is evidence, a black-chinned with a few other hummingbird’s feathers in its claws.
This Black-chinned Hummingbird has some feathers of another hummingbird in its claws.
