Taxonomy
Formerly placed in the genus Accipiter, it is the
It was formerly thought that the Accipiter collaris formed a superspecies with "A." superciliosus, but it was recently shown that A. superciliosus might not belong in the Accipiter genus. This called into question the traits of defining features of the Accipiter genus, putting Accipiter collaris and other species previously thought to be in the Accipiter genus in an unknown position.[4]
Its current genus name, “Accipiter”, is Latin for “hawk”,[5] its species name, “collaris”, is Latin for “collar”, or “neckband”[5]
Description
This is a small, rare hawk that lives in forests in mid elevations. It has black upperparts and a white band on the back of its neck. Its underparts are white, and it can have blotches on its sides. Young semi-collared hawks are more brownish. It usually stays in the forest and preys on smaller birds, occasionally soaring.
When calling to others, semicollared hawks create a high-pitched, almost whistle-like, sound. In addition, some semicollared hawks have been heard singing songs that consist of the repetition of a mid-pitch vvt-vvt sound. These songs also contain a series of four quick high-pitched calls that successively get higher.[6]
Distribution and habitat
This species is known to be non-migratory.[4]
Colombia
The semicollared hawk is seen (although rarely) in the 600-1800m range in wet and humid forests, but seen more often in the Pacific slope in
Ecuador
They are highly unlikely to live within the subtropical areas on the slopes of the Andes. Recorded from around 1,500-2,200 m, the semicollared hawk is only situated in western Napo and Zamora-Chinchipe on the eastern slope and Pichincha on the western slope. One has been spotted in Otanga, in northwestern Ecuador, at 1,900 m. This is neighboring the Mindo-Tandayapa area, where most other records of semi collared hawks have occurred.[4]
Venezuela
Between 1,300-1,800 m in the humid montane forests in the Andes of Táchira, northwest Barinas, and Mérida, there have only been two claims of spotting this species. The semicollared hawk is extremely scarce in this region.[4]
Behavior
Diet
There is very little information on the feeding behavior of the semi-collared hawk, but In northern Colombia, a male was found with
Breeding
The generation length (average age before parenthood) of this species is 5.1 years.[1]
Predation and threats
Primarily due to agricultural expansion, forestry has declined. While this does not seem to currently affect the population, it may present a threat in the future.[1]
