Ruby-throated Hummingbird

My Saturday Bird this week is the Ruby-throated Hummingbird (Archilochus colubris). The only Hummingbird species that breeds in eastern North America.

This is a male photographed in mid summer. After courtship and mating the male leaves the female to raise the young. Males start heading south as soon as early August.

I selected this photo to show the worn plumage. The bird will moult its plumage when on its wintering grounds. They spend the winter in Central America, Mexico or Florida. Some birds make a 900 mile flight across the Gulf of Mexico.

Saturday Bird: Ruby-throated Hummingbird

Thanks Becky. They’re a pretty aggressive species. This male was defending our hummingbird feeder from all comers. It seems strange that it will chase away birds that could have been its mate and potentially its offspring.

I wonder if the aggression is due to the demands of needing to feed so frequently and the need to build up fat reserves prior to migration.
