Adult males have a bright red feather patch on its throat. Females and juveniles have white throats with possibly a tiny red feather or two. In this photo I show what I believe to be a juvenile female.
In a woodland situation you will most likely hear the hum of this tiny bird's rapid wing beat before you will see it. Their fussy vocalization might be compared to a tiny squeak toy.
An adult ruby-throated hummingbird has a wing span of between 3 and 4 inches and tiny short legs. Its beak is long compared to its body. It has a long tongue, which helps it reach the nectar deep inside flowers with long throats such as trumpet vine blossoms. Close observation of these tiny birds will reveal that they also eat insects like mosquitoes and small spiders.
Hummers can fly faster than most birds and are the only birds capable of flying backward.
