The simple answer to this is south. While that may seem like I’m being a bit corny, it isn’t that far from being the truth. Ruby-throated Hummingbirds have a rather large known wintering range. Banding data shows that individuals may winter in the far southern tips of the U.S. all the way to far southern Central America. According to the Cornell Lab of Ornithology, just over half of the world’s population winters in Mexico.
