The Ruby-throated Hummingbird (Archilochus colubris) is a species of hummingbird. This small animal is the only species of hummingbird that regularly nests east of the Mississippi River in North America.
Looking for hummingbird nests? They're small and often hidden, but this image by Bill Hilton Jr.via Operation Ruby Throat will give you an idea of what to look for. Do not remove any nests you find because hummers and other birds reuse their nests.
