- Buteo nitidus
aka Grey Hawk. Includes Buteo plagiatus/Asturina plagiata (see Taxonomy).
Identification
Adults are generally easily recognized by the grey-and-white barred underparts and broadly white-barred black tail.
Distribution
See Taxonomy
Habitat
Woodland and forest, but sometimes in more open habitats with scattered trees. Mainly in lowlands, but locally up to 1800 m (5900 ft). Generally fairly common, but rarer in its limited US range.
Behavior
Feeds on a wide range of small to medium-sized animals, mostly reptiles, but also birds, rodents and insects.
Taxonomy
Work by Riesing et al. (2003) suggest Buteo is the correct genus, but it is still commonly placed in the genus Asturina, in which case the species name is modified to nitida.
It is sometimes split into two species:
- Grey Hawk (Buteo plagiatus aka Asturina plagiata). Monotypic. Found from far S. USA to NW Costa Rica. Larger and darker than the following.
- Grey-lined Hawk (Buteo nitidus aka Asturina nitida). In addition to the nominate race, it also includes races costaricensis and pallida. It is found from SW Costa Rica, through central America, and most of lowland N. and C. South America, as far south as SW Ecuador on the Pacific coast and N. Argentina east of the Andes.
When the two are considered conspecific, the combined species is variably referred to as the Grey Hawk or the Grey-lined Hawk.
