Swifts and Hummingbirds: Apodiformes - Conservation Status

birds species princeton endangered

Some species of swifts and hummingbirds face threats to their survival, according to the World Conservation Union (IUCN). Nine hummingbird species are Critically Endangered, facing an extremely high risk of extinction, as their habitat is lost due to development, farming, and logging. Six hummingbird and swift species are Endangered, facing a very high risk of extinction. Brown tree snakes accidentally brought to Guam by ships ate many of these birds on the island. Other swiftlets died when pesticides were sprayed to kill insects.
