The Cuban kite (Chondrohierax wilsonii) is a bird of prey in the family Accipitridae which also includes many other diurnal raptors such as kites, eagles and harriers. It is endemic to Cuba.

Contents

This species is classified as critically endangered by BirdLife International and the IUCN. The current population is estimated 50 to 249 mature birds. In the last 40 years the species has only been observed a handful of times with the latest published sighting in 2010 in Alejandro de Humboldt National Park. [1]

The Clements Checklist considered it as subspecies of the hook-billed kite until its 2022 revision. [2] A molecular phylogenetics analysis using mitochondrial DNA suggests that it warrants species status having diverged from the mainland lineage approximately 400,000 to 1.5 million years ago. [3]

Forest destruction and degradation is the leading cause of population decline, as well as the reduction in prey snail numbers and persecution by local farmers. Its apparently tame nature makes it an easy target for shooters. [4]

Description

The Cuban kite is a little smaller than the hook-billed kite. Males have gray upperparts, black bars on the tail, and the underparts evenly barred grayish and white. Females resemble the Grenada form of hook-billed kite, but the brown barring on the underparts is less rufescent. The bill of Cuban kite is yellowish, in contrast to hook-billed kite's mostly dark bill. [5]

Behavior

Cuban kites feed on colored tree snails and slugs, which they find in the forest undergrowth, for which the deeply hooked bill is thought to be adapted for. [4] [3]

The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents and a number of oceanic island groups. Some species are migratory. The family contains 256 species which are divided into 12 subfamilies and 75 genera.

<span class="mw-page-title-main">Kite (bird)</span> Bird of prey

Kite is the common name for certain birds of prey in the family Accipitridae, particularly in subfamilies Milvinae, Elaninae, and Perninae. The term is derived from Old English cȳta, possibly from the onomatopoeic Proto-Indo-European root *gū- , "screech."

The black kite is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae, although some populations have experienced dramatic declines or fluctuations. Current global population estimates run up to 6.7 million individuals.

<span class="mw-page-title-main">Black-shouldered kite</span> Small raptor found in Australia

The black-shouldered kite, also known as the Australian black-shouldered kite, is a small raptor found in open habitats throughout Australia. It resembles similar species found in Africa, Eurasia and North America, including the black-winged kite, a species that has in the past also been called "black-shouldered kite". Measuring around 35 cm (14 in) in length, with a wingspan of 80–100 cm (31–39 in), the adult black-shouldered kite has predominantly grey-white plumage and prominent black markings above its red eyes. It gains its name from the black patches on its wings. The primary call is a clear whistle, uttered in flight and while hovering. It can be confused with the related letter-winged kite in Australia, which is distinguished by the striking black markings under its wings.

The sharp-shinned hawk or northern sharp-shinned hawk, commonly known as a sharpie, is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species: white-breasted hawk, plain-breasted hawk, and rufous-thighed hawk. The American Ornithological Society and some other checklists keeps all four variations conspecific.

The Peregrine Fund is a non-profit organization founded in 1970 that conserves threatened and endangered birds of prey worldwide. The successful recovery of the peregrine falcon in the United States, which was removed from the U.S. Endangered Species List in 1999, enabled the organization to expand its mission to include other endangered raptors around the world. The Peregrine Fund is headquartered at its World Center for Birds of Prey in Boise, Idaho, on a 580-acre (2.3 km2) campus with breeding and research facilities, an administrative office, interpretive center, research library, and archives.
