The Barbary falcon is a subspecies of the peregrine falcon that inhabits parts of North Africa, from the Canary Islands to the Arabian Peninsula. There was discussion concerning the taxonomic status of the bird, with some considering it a subspecies of the peregrine falcon and others considering it a full species with two subspecies.
The largest falcon is the gyrfalcon at up to 65 cm (26 in) in length. The smallest falcon species is the pygmy falcon, which measures just 20 cm (7.9 in). As with hawks and owls, falcons exhibit sexual dimorphism, with the females typically larger than the males, thus allowing a wider range of prey species. [10]
The black morph is similar but has a strongly black-spotted underside, rather than finely barred as in the peregrine and the brown-morph gyrfalcon.

The species shows no sex-based colour differences; juveniles are ...
The animated image of the Moon's surface shows the effects of atmospheric turbulence on the view. Turbulence in Earth's atmosphere scatters the light from stars, making them appear brighter and fainter on a time-scale of milliseconds. The slowest components of these fluctuations are visible as twinkling (also called scintillation).
Eleonora's falcon (Falco eleonorae) is a medium-sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis . The sooty falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species .

Environments in which subsurface life has been found [1]. The deep biosphere is the part of the biosphere that resides below the first few meters of the ocean's surface. It extends 10 kilometers below the continental surface and 21 kilometers below the sea surface, at temperatures that may reach beyond 120 °C (248 °F) [2] which is comparable to the maximum temperature where a metabolically ...
