The family's taxonomy is unsettled; the Clements taxonomy lists 235 species [2] and BirdLife International's Handbook of the Birds of the World lists 254 [3]. This list is presented according to the IOC taxonomic sequence and can also be sorted alphabetically by common name and binomial.
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In December 2019, the International Union for Conservation of Nature (IUCN) listed 460 endangered avian species. [1] Of all evaluated avian species, 4% are listed as endangered. No subpopulations of birds have been evaluated by the IUCN.
As of December 2019, the International Union for Conservation of Nature (IUCN) listed 223 critically endangered avian species, including 19 which are tagged as possibly extinct or possibly extinct in the wild. [1] [2] 2% of all evaluated avian species are listed as critically endangered. No subpopulations of birds have been evaluated by the IUCN.
In 2021, the agency seemed ready to declare the so-called Lord God Bird extinct: The US Fish and Wildlife Service announced plans to remove 23 species, including the ivory-billed woodpecker, from ...
The red-cockaded woodpecker is small- to mid-sized species, being intermediate in size between North America's two most widespread woodpeckers (the downy and hairy woodpeckers). This species measures 18–23 cm (7.1–9.1 in) in length, spans 34–41 cm (13–16 in) across the wings and weighs 40–56 g (1.4–2.0 oz).
The ivory-billed woodpecker is classified as critically endangered by the IUCN, [65] and some authorities believe it may already be extinct. In a global survey of the risk of extinction faced by the various bird families, woodpeckers were the only bird family to have significantly fewer species at risk than would be expected. [66]
Red-cockaded woodpeckers were one of the first species designated as “endangered” in the United States in 1970, and the birds received full protections with passage of the Endangered Species Act of 1973. Since then, habitat restoration and protection on both public and private lands have helped the species to partially recover.
The species — several birds, mussels, two species of fish and the Little Mariana fruit bat last seen in Guam in 1968 — have been listed as endangered for decades, according to the U.S. Fish ...
