Ruby-throated Hummingbird
A juvenile male Ruby-throated Hummingbird (Archilochus colubris) hovering. The species, the smallest bird that breeds in the Eastern United States and Eastern Canada, is named after a distinctive red throat patch exhibited by adult males. Females and juveniles, however, do not have such a patch.Photo: Pslawinski
