The semicollared hawk (Microspizias collaris) is a rare bird of prey species in the family Accipitridae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is potentially being affected by habitat loss.
Formerly placed in the genus Accipiter, it is the sister species of the tiny hawk (M. superciliosus). The latter was thought to be the only species in Accipiter yet studied which has a large procoracoid foramen. The collaris-superciliosus superspecies also differs from the typical sparrowhawks in other respects of its anatomy and as regards DNA sequence. Consequently, the old genus Hieraspiza may be more appropriate for them. In 2021, a phylogenetic study found it and the semicollared hawk to form a distinct group from the rest of Accipiter, that is sister to Kaupifalco . For this reason, both were reclassified into the new genus Microspizias . [2] [3]
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]
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]
This species is known to be non-migratory. [4]
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 Antioquia, Valle, and Cauca, in the central Andes in Tolima and Cauca, in the eastern Andes in Norte de Santander, Santa Marta Mountains, and on the eastern slope of the eastern Andes in western Meta. [4]
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]
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]
There is very little information on the feeding behavior of the semi-collared hawk, but In northern Colombia, a male was found with passerine feathers in its stomach. Another semicollared hawk was found chasing Dusky Bush Tanagers at Otanga in the western slopes of the Andes in northwestern Ecuador. These suggest that this species mainly, or only, feeds on birds. [4]
The generation length (average age before parenthood) of this species is 5.1 years. [1]
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]
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 255 species which are divided into 70 genera.
Accipiter is a genus of birds of prey in the family Accipitridae. With 49 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although with the exception of the American goshawk almost all New World species are simply known as "hawks". They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.
The Accipitrinae are the subfamily of the Accipitridae often known as the "true" hawks, including all members of Accipiter and the closely related genera Erythrotriorchis, and Megatriorchis. The large and widespread genus Accipiter includes goshawks, sparrowhawks, the sharp-shinned hawk and others. They are primarily woodland birds that hunt by sudden dashes from a concealed perch, with long tails, broad wings and high visual acuity facilitating this lifestyle. In light of recent genetic research, the kites of the traditional subfamily Milvinae may also belong to this group.
The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk. The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance to other sparrowhawk species including the Chinese goshawk and Eurasian sparrowhawk. They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage.
The lizard buzzard, or lizard hawk, is a bird of prey in the family Accipitridae. It is native to Sub-Saharan Africa. Despite its name, it may be more closely related to the Accipiter hawks than the Buteo buzzards.
The Levant sparrowhawk is a small bird of prey. It measures 32–38 cm (13–15 in) in length with a wingspan of 65–75 cm (26–30 in). The female is larger than the male, but the difference is not as marked as with Eurasian sparrowhawk. The adult male is blue-grey above, with dark wingtips, and barred reddish below.
The brown goshawk is a medium-sized bird of prey in the family Accipitridae found in Australia and surrounding islands.
The grey goshawk is a strongly built, medium-sized bird of prey in the family Accipitridae that is found in eastern and northern Australia. The white morph of this species is known as the white goshawk.
The tiny hawk is a small diurnal bird of prey found in or near forests, primarily humid, throughout much of the Neotropics. It is primarily a bird-eater, and is known to prey on hummingbirds.
The bicolored hawk is a species of bird of prey in the family Accipitridae. It is found in forest, woodland, second growth, plantations, and wooded savanna in southeastern Mexico, Central America, and northern and central South America. Though generally uncommon, it is the most common species of Accipiter in most of its range, but it does not occur at altitudes above 2,700 metres (8,900 ft) such as the highest parts of the Andes.
Gundlach's hawk is a species of bird of prey in the family Accipitridae. It is one of 21 endemic bird species of Cuba. The common name and Latin binomial commemorate the German-Cuban ornithologist Juan Cristobal Gundlach (1810–1896). It is threatened by habitat loss and human persecution.
Henst's goshawk is a species of bird of prey in the family Accipitridae. It is a large, diurnal bird endemic to the island of Madagascar. It is an obligate forest species that occurs at very low densities on the island and is rarely seen. It can only occupy the primary and secondary forests found within the island. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and plantations.
The grey-bellied hawk or grey-bellied goshawk is a fairly large and rare species of forest-dwelling South American bird of prey in the family Accipitridae.
The rufous-breasted sparrowhawk, also known as the rufous-chested sparrowhawk and as the red-breasted sparrowhawk, is a species of bird of prey in the family Accipitridae. It is found in Angola, Democratic Republic of the Congo, Eritrea, Eswatini, Ethiopia, Kenya, Lesotho, Malawi, Mozambique, Rwanda, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.
The African goshawk is an African species of bird of prey in the genus Accipiter which is the type genus of the family Accipitridae.
The white-rumped hawk is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru, and Venezuela.
The semicollared puffbird is a species of near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is one of seven species of the genus Malacoptila. It is found in Bolivia, Brazil, and Peru.
The Eurasian goshawk is a species of medium-large bird of prey in the family Accipitridae, a family which also includes other extant diurnal raptors, such as eagles, buzzards and harriers. As a species in the genus Accipiter, the goshawk is often considered a "true hawk". The scientific name is Latin; Accipiter is "hawk", from accipere, "to grasp", and gentilis is "noble" or "gentle" because in the Middle Ages only the nobility were permitted to fly goshawks for falconry.
Aviraptor is an extinct genus of small accipitrid bird of prey known from the Oligocene of Poland. It contains one species, Aviraptor longicrus. It was named in 2020 by Gerald Mayr and Jørn Hurum based on a single nearly complete specimen. The genus name is derived from the Latin words avis meaning “bird” and raptor meaning “thief” and the species name is derived from the Latin words longus meaning “long” and crus meaning “leg”.
Microspizias is a genus of bird of prey in the family Accipitridae. It contains the following species:
