Scissor-Tailed Hummingbird (image) University of Utah Caption Venezuela's scissor-tailed hummingbird has an existing habitat of less than 100 square miles of humid mountain forest. It is currently considered threatened with extinction, and computer models of expected extinctions due to climate change indicate that this species will be among the most likely to go extinct by the end of the century if global warming continues.
