100 More Species #49: Ruby-throated hummingbird

Ruby-throated hummingbird Archilochus colubris

Hummingbirds are only found in the New World, and in the northeast the only hummingbird that one is likely to encounter is the ruby-throat. A couple other species are infrequent visitors, but the ruby-throat spends the whole summer in our area, nesting and raising tiny chicks. The group is much more diverse in the west, and especially in the Neotropics.

Hummingbirds are truly unique among birds, with a wing-beat frequency of over 50 per second, allowing them to hover in place, fly backwards or straight up, and perform aerial acrobatics no other vertebrate can manage. They feed mainly on flower nectar, supplemented with small insects and spiders. Commercially available hummingbird feeders are available, but ours has attracted only ants. Our cheap butterfly bushes--nearly dead when Alexis rescued them from the close-out shelf--seem to be what drew this female to the yard. The species is named for the metallic red feathers on the male's throat.

A nest spun of spiderwebs and dog hair (provided by the bird curator's dog).

do they make new nests or reuse them?

I doubt they reuse nests. This was the second nest that this bird built this year. They migrate long distances and it's hard to picture them finding last year's nest.
