rekordy: Eurasian goshawk

Evidence: 100 • authority: 72

The Eurasian goshawk (; Astur gentilis) 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. It was formerly placed in the genus Accipiter. It is a widespread species that inhabits many of the temperate parts of Eurasia. Except in a small portion of southern Asia, it is the only species of "goshawk" in its range and it is thus often referred to, both officially and unofficially, as simply goshawk. It is mainly resident, but birds from colder regions migrate south for the winter. As of 2023, goshawks found in North America are no longer considered to be conspecific, but are now…

American Goshawk (Astur atricapillus)

Colonisation of the Eurasian Goshawk Astur gentilis into an urban environment in Finland. There are several hypotheses for the significance of urban colonisation of animals but an exhaustive explanation is still missing. The question arises: is the colonisation a successful process or a detrimental misstep? Here, I describe the first case of urban colonisation of the Eurasian Goshawk in Finland, where the species is traditionally known as a shy, resident bird of remote wilderness and rural areas. I predict, that if the urban habitats are more favourable for goshawks than the habitats in Finland in general, 1) population trends should be more positive, 2) breeding output should be higher, an…

As of November 2024, the List of Wildlife Species at Risk has more than 600 entries for Canadian wildlife species considered at varying risks of extinction, including 301 classified as endangered species, 147 threatened species, 200 special concern, and 23 extirpated (no longer existing in the wild in Canada, but exists elsewhere). About 65 percent of Canada's resident species are considered "Secure". More than 30 wildlife species have become extinct in the wild since the arrival of European settlers. The Government of Canada maintains a list of all plant and animal species, or designatable units (DUs) thereof, federally recognized as special concern, threatened, endangered, extirpated, and…

In the United States, chickenhawk or chicken hawk is an unofficial designation for three species of North American hawks in the family Accipitridae: Cooper's hawk (also called a quail hawk), the sharp-shinned hawk, and the Buteo species red-tailed hawk. The term "chicken hawk", however, is inaccurate. Although Cooper's and sharp-shinned hawks do primarily hunt other birds, chickens do not make up a significant part of their diets; red-tailed hawks may opportunistically hunt free-range poultry, but are chiefly predators of mammals such as rodents and rabbits. Historically, misinterpretation of the name "chicken hawk" has labelled these birds as pests, hence justifying their slaughter. Offici…

The American goshawk (Astur atricapillus) is a species of raptor in the family Accipitridae. It was first described by Alexander Wilson in 1812. The American goshawk was previously considered conspecific with the Eurasian goshawk but was assigned to a separate species in 2023 based on differences in morphology, vocalizations, and genetic divergence. It was formerly placed in the genus Accipiter. It is mainly resident, but birds from colder regions migrate south for the winter. In North America, migratory goshawks are often seen migrating south along mountain ridge tops at nearly any time of the fall depending on latitude.

Two new species of Grylloblatta Walker, 1914 (Grylloblattodea: Grylloblattidae) from western North America, and a neotype designation for G. rothi Gurney 1953. Grylloblatta rothi Gurney, 1953 is redescribed and a neotype is designated from Cultus Mountain in the Oregon Cascades, U.S.A. Two new species of Grylloblatta are described, bringing the total number of Grylloblatta species to 15. Grylloblatta chintimini new species is described from Marys Peak in the Coast Range of Western Oregon, where it occurs on snowpack near the 1250 m summit. Grylloblatta newberryensis new species is described from Newberry Volcano in Central Oregon, where it is associated with snowfields overlying geologicall…
