Endangered Birds

Home / Endangered Birds

An “endangered species” is any species of fish, animal, or plant that is in danger of extinction throughout all or a significant portion of its range. Subspecies and distinct populations of vertebrate species may also be listed. There are approximately 1500 endangered species, 900 in the United States. A “threatened species” is any species of fish, animal, or plant that is likely to become an endangered species within the foreseeable future. There are 270 threatened species, 230 in the United States. A candidate species is one whose status warrants listing but whose listing is precluded by lack of administrative resources and/or funding. See the IUCN Red Lists for a list of worldwide threatened species and an informative explanation of what being in danger of extinction really means.

Today, 2009, it is estimated that one of every eight bird species in the world is at risk of extinction and in the U.S. and England it is closer to one in four. See also Extinct Birds.

PEREGRINsmPeregrine Falcon

The population dropped dramatically worldwide after the 1940’s due to DDT, illegll hunting, and illegal taking of young falcons by would-be falconers. But the protection afforded by the Endangered Species Act has allowed the Peregrine to recover and the bird was removed from the endangered list in 1999. More information from the Peregrine Fund.

“The crested shelduck is classified as a member of the order Anseriformes (Screamers and ducks) and is a member of the family Anatidae. It is classified as a critically endangered species due to an estimated population of less than 50 mature crested shelducks. The species may already be extinct – it is kept in the critically endangered category because of recent unconfirmed reports of sightings. If the species still exists, it can be found in eastern Asia.”
