Red tailed hawk птица

Red-tailed Hawk Identification

Large with a red tail. Mostly pale below, with a darker belly band, wing tips, and edges of the flight feathers. Head brown with a white throat.

Adult (borealis)

Large with a red tail. Mostly brownish above with variable white in the wing coverts and lower back forming a pale ‘V’ on the upperwings. Eastern subspecies (borealis) tends to have plain red tail with neat black band near the tip.

Adult

When they detect prey on the ground, they glide or flap-and-glide downward, pushing their legs forward when nearing the prey and impaling it with their talons.

Adult light morph (calurus/alascensis)

Western subspecies (calurus) differs in being more richly colored below on average, and more heavily-marked. The body plumage is polymorphic in the western subspecies, occurring in light (as here), intermediate, and dark morphs.

Adult light morph (calurus/alascensis)

The red tail is more obvious when viewed from above. Otherwise all dark brown with light barring in the flight feathers.

Adult

Soars with wings held in a shallow V and «fingers» spread. Stoops to the ground by tucking its wings into its body.

Adult dark morph (calurus/alascensis)

Some dark morphs are strongly reddish-brown below, especially on the chest.

Adult dark morph (calurus/alascensis)

Dark chocolatey-brown body and wing linings, with paler flight feathers lightly barred and contrasting with dark wing tips and edges to the flight feathers.

Adult

Often perches motionless in trees along roadsides or slowly scans for prey from its perch.

Adult light morph (abieticola)

Large with a red tail. Mostly pale below, with a heavy darker belly band. Dark wing tips and edges to flight feathers contrast with paler wings.

Adult dark morph (Harlan’s)

Chocolatey-brown below, with lightly barred whitish flight feathers, dark wing tips and edges to the flight feathers, and a mostly whitish tail with a dark tip.

Adult

When hunting, often hangs in the air scanning for prey below; a behavior known as kiting.

Adult light morph (Harlan’s)

Mostly pale below with a heavy dark belly band, dark wing tips and edges to the flight feathers, and dark tips to a white tail.

Adult dark morph (Harlan’s)

Adult Harlan’s tail pattern highly variable above, characterized by white, gray, and black mottling and longitudinal streaking. Some lack red altogether.

Adult (Krider’s)

Subspecies characterized by extremely lightly-marked underparts with faint patagial mark (often rufous toned) and faint to absent belly band.

Adult (Krider’s)

Subspecies typically has rufous-toned upperparts with extensive white spangling, and whitish-based tail with red to pinkish tip.

Adult (costaricensis)

Birds in Costa Rica and Panama have rufous bellies and wing linings, pale flight feathers contrasting with dark wingtips and flight feather edges, and chocolatey-brown head and shoulders.

Juvenile light morph (calurus/alascensis)

Heavily streaked below, with bold barring on the wings, dark wingtips, and a lightly barred pale tail.

Juvenile dark morph (calurus/alascensis)

Very heavily streaked below, with darkly checkered wing linings, boldly barred wings with dark wingtips, and a finely barred brown and white tail.

Juvenile dark morph (Harlan’s)

Very heavily streaked below, with darkly checkered wing linings, boldly barred wings with barred wingtips, and a finely barred brown and white tail.

Juvenile (Krider’s)

Very pale, almost white head. Brown above mixed with white feathering, and finely barred wings and tail.

Adult (borealis)

Pale below with light reddish-brown streaking on the chest and a bold brown belly band. Head brown with some darker markings. Red tail often not visible on perched birds.

Juvenile (borealis)

Pale below with a broad and bold brown belly band. Head brown mixed with white feathering. Tail barred brown and whitish.

Juvenile (Krider’s)

Adult dark morph (calurus/alascensis)

Eats a wide variety of prey, including snakes, and occurs in many different habitats.

Adult (borealis)

Often mobbed by smaller birds, especially during the nesting season.

The Four Keys to ID

Red-tailed Hawks are large hawks with typical Buteo proportions: very broad, rounded wings and a short, wide tail. Large females seen from a distance might fool you into thinking you’re seeing an eagle. (Until an actual eagle comes along.)

Relative Size

The Red-tailed is the second-largest Buteo hawk in North America, after Ferruginous Hawk. between crow and goose

  Most Red-tailed Hawks are rich brown above and pale below, with a streaked belly and, on the wing underside, a dark bar between shoulder and wrist. The tail is usually pale below and cinnamon-red above, though in young birds it’s brown and banded. “Dark-morph” birds are all chocolate-brown with a warm red tail. “Rufous-morph” birds are reddish-brown on the chest with a dark belly. © Brian Sullivan | Macaulay Library

  You’ll most likely see Red-tailed Hawks soaring in wide circles high over a field. When flapping, their wingbeats are heavy. In high winds they may face into the wind and hover without flapping, eyes fixed on the ground. They attack in a slow, controlled dive with legs outstretched – much different from a falcon’s stoop.

  Regional Differences

  Red-tailed Hawks have extremely variable plumage, and some of this variation is regional. A Great Plains race called «Krider’s» hawk is pale, with a whitish head and washed-out pink in the tail. Light-morph western birds tend to be more streaky on the underparts than eastern Red-tails; south Texas forms are darker above, without the dark belly band most other Red-tails have. Dark-morph birds can occur anywhere but are more common in western North America — particularly in Alaska and northwest Canada, where the all-dark «Harlan’s» race is common.

  Description [ ]

  The Red-tailed Hawk is about 19 to 21 inches long with a 54 to 58 inch wingspan. Its underbelly is typically dark tan with its small dark brown feathers. The underside of its wings are of a similar tone. The primaries and secondaries are both barred with brown stripes. It has a rust toned tail with faint clay brown stripes in which its name derives. On the top side of its wings, it is typically a light brown or a dark sooty brown. It has either dark red or brown eyes. It has a distinctively handsome face with slight whisker marks, similar to that of a falcon. Its legs are yellow with large talons. they are about 3 quarters of an inch long. It can weigh up to 4 pounds. Its wings are long broad and has heavily fingered tips. That signifies a good soaring platform. It has a long, broad tail. That shows that it is agile and able to show a quick turn of speed.

  Voice [ ]

  The Red-tailed Hawk has a distinctive call, a harsh, loud, descending screech.

  Behaviour [ ]

  This bird has a basic hawk attitude. It is shy around people in rural areas but in urban areas, It has been known to dive out of the sky on a passer-by but only when they aren’t looking. It is mainly due to nesting. It is commonly attacked by smaller birds. Depending on the size, it wont fight back. If it is another hawk species, it will invert and bear its talons. If it were a passerine type birds such as crows, ravens, magpies, thrushes and swallows it will simply take the punishment or make a high speed getaway.

  Hunting [ ]

  A very versatile hunter, it will drop out the sky at break neck at speed, swing its talons at the last minute and skewer its prey, usually killing it on impact. It eats any thing from carrion to deer fawns. Its primary prey is rodents but it will not hesitate to take on bird prey. However, smaller birds can often evade the Red-tail Hawk when being chased. Other prey include snakes, lizards, and insects.

  Breeding [ ]

  The nest, built by both the male and the female, is a platform of sticks lined with finer material such as evergreen needles. The eggs, usually 2 or 3, white and occasionally with brown markings, are incubated by both parents for 30-35 days. The young fledge in 45-46 days.

  Distribution and habitat [ ]

  Found in the majority of North and Central America, the Red-tailed Hawk is a year-round resident or partial migrator throughout most of its range. A very common raptor, it occurs in a wide variety of habitats, including open woodlands, plains, prairie groves, deserts, and even urban areas. It is often seen circling above open fields and roadsides.

  Red-tailed Hawk (Buteo jamaicensis)

  

  Что? Не очень похож на того, кого видели вы ?
  Но это не значит, что это разные виды птиц.
  Краснохвостый канюк — очень общее название. Существует много подвидов этой птицы, которые иногда совершенно не похожи друг на друга. Некоторые темнее, некоторые светлее, а бывают даже почти белые.
  2

  

  Но почти у всех у них есть одно отличие, по которому их объединяют в один вид. Красный хвост.
  Лучше всего красный хвост виден в полёте.
  3

  Но даже если вы ясно видите, что у птицы не красный хвост, то это опять не значит, что это не канюк. У молодых особей хвост тёмный и полосатый.

  Краснохвостого канюка можно определить и по рисунку на нижней стороне крыльев.
  6

  

  У молодых особей он менее чёткий.
  7

  

  А у светлых меньше рыжего цвета.
  8

  Охотятся канюки часто со столбов вдоль дорог: сидят, высматривают добычу. Потом резкий бросок вниз, и с добычей обратно на столб.

  Один раз я стояла на холме, а прямо напротив меня на столбе сидел канюк и с аппетитом ел мышку. И, конечно же, у меня в тот момент не было фотоаппарата! Ладно, буду надеяться, это был не последний раз.
  Обратите внимание, как сильно различаются все эти птицы, но у всех у них на груди оперение напоминает манишку.
  11

  

  На деревья краснохвостые канюки, конечно, тоже садятся.
  12

  

  Очень часто у птиц бывают любимые деревья. Так что если вы один раз заметили канюка на каком-то дереве, то существует большая вероятность, что и в следующий раз вы его застанете там же.
  13

  

  Ранним утром я часто вижу канюков сидящих прямо на земле, уже насытившихся.
  14

  

  Никак не могу застать их за завтраком, но предлагаю посмотреть канюка за едой у ololaiki вот здесь, а я пока успеваю только к следующему процессу их пищеварения.
  15

  Так вот, возвращаясь к различным подвидам, немного обособленно существует чёрный краснохвостый канюк, его даже хотели выделить в отдельный вид.
  На фотографии непонятен размер птицы, но она такая большая, что издалека я приняла её за молодого орлана. Но оказался всё же канюк.

  У этих птиц и рисунок на крыльях отличается, больше чёрного цвета.
  18

  

  Я постаралась показать канюков с самым различным оперением, которых встречала сама. Но в природе вариаций намного больше, например, белого Krider’s Hawk я и сама ни разу не видела.
  В этих птицах есть что-то такое притягательное, что сколько бы раз ты их не фотографировал, невозможно пройти мимо очередного канюка подумав: «Ну, их у меня и так уже много.»
  Каждый раз кажется, что вот именно такого у тебя ещё нет.

  Теперь выкладываем посты в ЖЖ не тогда, когда хочется, а тогда, когда можется, я так понимаю. Ладно, попробуем так.
