Hen Harrier

The Hen Harrier (Circus cyaneus) or Northern Harrier (in North America) is a bird of prey. It breeds throughout the northern parts of the northern hemisphere in Canada and the northernmost USA, and in northern Eurasia. This species is polytypic, with two subspecies. Marsh Hawk is a disused name for the American form.[2]

It migrates to more southerly areas in winter. Eurasian birds move to southern Europe and southern temperate Asia, and American breeders to the southernmost USA, Mexico and Central America. In the mildest regions such as France, Great Britain and the southern US, Hen Harriers may be present all year, but the higher ground is largely deserted in winter.

Aguilucho palido

Circus cyaneus es una especie zoológica de aguilucho.

Caza buscando en el suelo con un vuelo de planeo rápido y bajo. Suele mantener las alas en forma de V obtusa, con lo que puede sorprender a aves pequeñas o incapacitadas, pequeños roedores e incluso insectos grandes. Habita en parajes abiertos como páramos, pantanos, praderas esteparias o dunas de arena.

Pone hasta 9 huevos, de color blanco-azulado, en un nido realizado en el suelo; se les puede ver descansando en grupos de hasta 10 ejemplares. Las hembras alcanzan los 5 dm de longitud, mientras que los machos apenas superan los 4, llegando a alcanzar los 700 y 400 g de peso respectivamente; la envergadura de sus alas es de unos 125 cm.

También se le conoce como aguililla rastrera, aguilucho de ciénaga, o gavilán campestre pálido o de ciénaga.

En inglés se le conoce como Hen Harrier.

Sharp-shinned

The Sharp-shinned Hawk (Accipiter striatus) is a small hawk. In fact “Sharpies” (as they are abbreviated by North American birdwatchers), are the smallest to reside in USA and Canada, though some Neotropical species are smaller (notably the aptly named Tiny Hawk). The taxonomy is far from resolved, with some authorities considering the southern taxa three separate species: White-breasted Hawk (A. chionogaster), Plain-breasted Hawk (A. ventralis) and Rufous-thighed Hawk (A. erythronemius). See taxonomy for further on this.

Esparvero chico

Esta pequeña rapaz, cazadora de aves, tiene las alas anchas con unas plumas primarias puntiagudas que se extienden hacia fuera como dedos cuando se esta remontando. Su cola es larga y ancha. Caza volando a baja altura entre árboles y arbustos pájaros cantores tras una breve y veloz persecución. En vuelos más abiertos y altos, o cuando emigra, parece faltarle potencia. A su paso, grupos de aves pequeñas y de vuelo rápido como estorninos o golondrinas lo “agreden” en bandadas y ejecutan simulacros de ataque.

Cooper’s Hawk

Their breeding range extends from southern Canada to northern Mexico. They are generally distributed more to the South than the other North American Accipiters, the Sharp-shinned Hawk and the Northern Goshawk. Birds from most of the Canadian and northern-U.S.-range migrate in winter, and some Cooper’s Hawks winter as far south as Panama).

The Zone-tailed Hawk, (Buteo albonotatus), is a medium-sized hawk of warm, dry parts of the Americas. It feeds on small vertebrates of all kinds (other than fish), including birds up to the size of quail.

Grown birds are 47-55 cm (18.5-21.5 inches) in length with a wingspan of about 1.2 m (4 feet); their average weight is 810 g (1.8 lbs). Adult plumage is mostly blackish except that the flight feathers are barred with lighter gray (appearing solid gray from a distance) and the tail has three or four bands or “zones”, white from below and light gray from above, of which the one second from the tip is particularly broad and conspicuous. The cere and legs are yellow. Immatures are similar except for small white spots on the breast and tails with narrow gray and black bands and a broad dark tip.

The Red-tailed Hawk (Buteo jamaicensis) is a medium-sized bird of prey, one of three species colloquially known in the United States as the “chickenhawk.” It breeds almost throughout North America from western Alaska and northern Canada to as far south as Panama and the West Indies, and is one of the most common buteos in North America. There are fourteen recognized subspecies, which vary in appearance and range. It is one of the largest members of the genus Buteo in North America, weighing from 690 to 2000 grams (1.5 to 4.4 pounds) and measuring 45–65 cm (18 to 26 in) in length, with a wingspan from 110 to 145 cm (43 to 57 in). The Red-tailed Hawk displays sexual dimorphism in size, as females are 25% larger than males. Red-tailed Hawk plumage can be variable, depending on the subspecies. These color variations are called morphs, and a Red-tailed Hawk may be light, dark, or rufous.
