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.
For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered birds are listed ...
The largest surviving species is the great slaty woodpecker, which weighs 430 g (15 oz) on average and up to 563 g (19.9 oz), and measures 45 to 55 cm (18 to 22 in), but the extinct imperial woodpecker, at 55 to 61 cm (22 to 24 in), and ivory-billed woodpecker, around 48 to 53 cm (19 to 21 in) and 516 g (18.2 oz), were probably both larger.
According to the International Union for Conservation of Nature (IUCN), 77 bird species in the United States are threatened with extinction. [1] The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR (v. 2013.2, the data is current as of March 5, 2014 [1]).
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.
No subpopulations of birds have been evaluated by the IUCN. This is a complete list of near threatened avian species evaluated by the IUCN. Where possible common names for taxa are given while links point to the scientific name used 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 flight is strong and direct, and the calls are typically loud wild laughs. The drumming of these large birds can be heard from a great distance. Dryocopus woodpeckers chip out large holes with their strong bills while searching out insects, especially beetle larvae in trees. They will also take fruits, berries, and nuts.
