The Ruby-throated Hummingbird is a species of hummingbird that is small, with slender downcurved bill and generally spends the winter in Central America, Mexico, and Florida, and migrates to Canada and other parts of Eastern North America for the summer to breed.
The Rufous Hummingbird is known as one of North America's feistiest types of a hummingbird. They will relentlessly attack and aggressively drive away other hummingbirds, even the larger species of the southwest.
