The Ruby-throated hummingbird is the only hummingbird to breed East of the Mississippi River. However, the Rufous hummingbird is a migrant (meaning that it occasionally) ventures out of its territory. So the Rufous has been spotted in Pennsylvania rarely.

The Ruby-throated hummingbird is easy to identify. The iridescent feathers on the neck(gorget) of the male Ruby-throated are ruby colored in sunlight.

There are two species of hummingbirds that are native to New England. They are the ruby-throated hummingbird and the rufous hummingbird.

A Rufous Hummingbird has a wingspan of 3 - 4 cm and can flap/beat thier wings about 200 times a second

There are over 338 species of Hummingbirds, 16 species are found in North America and 3 are native to Florida. They are Black-chinned Hummingbird, Ruby-throated Hummingbird, and Rufous Hummingbird.

It seems the hummingbird picks the best location for her nest every year. Although there are a couple of species, (Rufous for one), that build their new nest on top of the old one.
