Gundlach's hawk

Description

The hawk is a medium-sized forest raptor. It stands between 43–51 cm in height and has a stocky body shape. The adult hawk has a dark bluish-gray upper body and wings, with a black head. The under body of the bird is a lighter color. It also has a striped tail that is rounded in flight. Immature hawks are mostly brown on the top and paler on the bottom, but with dark streaking down the body. Compared to other raptors such as the bicoloured hawk, Gundlach's hawks are shorter and faster.

Breeding

Typically, Gundlach's hawk nests high up in trees in the forest, such as pines, at about an altitude of 19–25 meters. Nesting high allows for hawks to prey on other birds that nest at much lower altitudes. Also, the altitude helps protect against predators. This is not uncommon to the accipiter genera. Nests are commonly made of smaller twigs from the trees that are found in the habitat.

Feeding

Gundlach's hawk feeds almost exclusively on birds. Because of the hawks large feet, it can feed on the Cuban Parrot, the Cuban Parakeet, and the Cuban Macaw (before it became extinct). Other birds in its diet include doves, pigeons,quail and chicken.

Voice

Gundlach's hawks has two main calls the kek and the "squeal" which is usually associated with species of its type, Accipiter. The vocalizations for these calls are different for the sexes with variations in pitch, tempo and length. The male call is softer,clearer, and shallower with a higher peak compared to the female who makes most of the calls and whose call is at a softer pitch.

Distribution and habitat

Gundlach's hawk is found only in Cuba. At one point it was common to find them throughout the country, however, now they can only be found in five isolated areas. The bulk of the population exists primarily on the eastern half of the island, in the two larger population centers, with the other three smaller populations on the west side of the island. They are able to live in a variety of habitats up 800 metres (2,600 ft). These include humid, dry, and pine forests. It does not have highly specialized habitat preferences needing only forests to conceal its hunting approaches Its natural habitats are dry forests and lowland moist forests. The species was never a common sight, but its population was dispersed throughout Cuba.

Status and conservation

Gundlach's hawk has been classified as endangered since 1994, due to its small and fragmented population. The past five years however, has shown a stabilization in the hawk's population trends. Population totals in Cuba were estimated to be about 400, including 270 mature hawks. This may warrant Gundlach's hawks to be reclassified as vulnerable. Perhaps the stabilization of the population can be attributed to conservation efforts that increase awareness of the hawk and its struggles. These conservation efforts include the public campaigning of Gundlach's hawk, the education of humans on the hawk and its environmental needs. Additional surveys of Cuba to assess current population and trends of Gundlach's hawk are required to determine the condition of the hawk in regards to extinction.

Threats

Gundlach's hawk faces a loss of habitat due to deforestation and logging in Cuba. It not only relies on trees for nesting but also for concealment as they prey on other birds. In addition to the loss of habitat the hawk also faces persecution from farmers because of its liking for poultry.
