Tube with russet-red tail

The tube with russet-red tail ( Buteo jamaicensis ) is a Oiseau of prey, or Rapace of North America.

Identification

The tube with adult tail russet-red with the tail of russet-red color (what gave him its name) finished or not by a black bar. It has long and broad wings. The Adulte has the back and the dark top of the wings brown. Its plumage is variable, energy of brown russet-red clearly with brown dark. The lower parts are clearer than the higher. The bottom of the Abdomen is paler than the remainder of the body, crossed by a dark band. The tail is uniformly russet-red and broad. The nozzle is short and hooked, the wax is yellow, the end is black. The eyes are brown dark. The legs and the fingers are yellow. The female is 25% larger than the male, but their plumages are identical. The immature one resembles to the adults, but it has the clearer eyes. It is more striated, its tail brown, is barred several dark bands. One finds two phases, the clear one and the bed, and at least 14 subspecies, with great differences on the level of the plumage and habitat.

Song

The tube with russet-red tail pad. The cry of the tube with russet-red tail is a kind of hennissement raspy “keeeear”. This cry varies with the age and the place. He is often heard when he planes. The young people emit soft and low pépiement, becoming deeper with the age. When the parents leave the Nid, the young people emit a piercing wail “the Klee-U.K.” repeated, to beg food.

Behaviors

The tube with russet-red tail drives out several manners, and captures any kind of preys. Generally, it remains on a pylon or a high perch, and melts on its prey as soon as it is located. But it can also drive out while flying, looking on the ground with attention, thanks to its piercing sight enabling him to detect the least movement at long distance. It can detect a mouse with 100 meters height.
Elle uses its powerful greenhouses as a weapon. It can also fly on the spot against the winds, seeking a prey on the ground. The tube with russet-red tail is active during the day. The small preys are related to the perch to be devoured there, while largest are consumed on the ground. During the bridal parade, the couple planes in broad circles while launching acute cries, with great height. The male plunges in to abrupt peak, then goes up, repeating these operations several times, and at the end, it approaches the female by in top, and extends its legs to briefly clutch the greenhouses of the female. They spiral then towards the ground, being released at the last time. The male can also catch a prey and to pass it to the female during the vol. the two partners couple themselves after this parade, upright on a perch, toilettant themselves reciprocally, and there, the female makes it possible the male to couple itself. The tube with russet-red tail, like the majority of the others birds, has body postures which express a language. Aggressive posture, with the drawn up head and body and the roughcast feathers; posture of tender, with the low head and the smooth feathers; air parades for the bridal period; undulating flight and piqués, used also in the defense of the territory. The tube with russet-red tail is coupled for the life. They are territorial birds, aggressively defending their zone, the female rather close to the nest, and the male through all the territory.

Habitat

The tube with russet-red tail lives in the grassy zones, the Marais bushy, but also in the deserted or the forests, since the sea level until variable altitudes, but close to a river, a Lac or a field.

Distribution

The tube with russet-red tail reproduces since the Alaska until the Labrador, and towards the south, until the Mexico, the Bahamas and the Caribbean, and Central America. It winters since the south of the Canada until worms the south. The birds of north migrate to the south in winter, but the majority of the other birds are resident at the year.

Flight

The tube with russet-red tail has a nimble and powerful flight, accomplishing lifting flights during the bridal parade. It is a raptor which flies high. It planes without effort with the wings tended in a V not very deep. It is a very active bird in flight, beating many the wings.

Nesting

The Nid of the tube with russet-red tail is a large bulky bowl. It is made brushwood, barks, and sheets, high in a tree or on the edge of a cliff. It can be re-used year after year. The nest is built by the two adults. Fresh materials, (coniferous needles of and green vegetable materials) are deposited in the nest throughout the period of Reproduction, in order to keep it clean. The female deposits 1 to 5 white eggs or bluish white, variablement mottled the brown one clearly. The Incubation lasts approximately 28 to 35 days, ensured by the two parents, more by the female which is nourished with the nest by the male. The young people are born nidicoles. They are covered with white sleeping bag and grow slowly. For this period, the female broods them, and the male nourishes chicks and the female while bringing food to the nest. The female nourishes the small ones with small pieces taken on the preys brought. The chicks can give up the nest with approximately 42 to 46 days, but this period can last up to ten weeks, time to learn how to fly and drive out. The young people reach to them sexual Maturité at the end of 3 years, and this species produces only one brooded per season.

Food mode

The tube with russet-red tail nourishes mainly small Mammifères (mouse, rats, squirrels, muskrats, weasels), birds (ducks, pigeons, rails, turtle-doves, peaks, pheasants, crows and seldom of the poultry), Reptiles and Amphibiens, Poisson and Invertébrés.

Protection/Threats

The tube with russet-red tail has few predatory, such as the Large-duke of America and the Corvidés, the russet-red foxes and the raccoons, which devour chicks and eggs. The tube with russet-red tail is threatened by the shootings, the various collisions, the loss of the habitat and the disturbances human on the sites of reproduction. The Empoisonnement by the Plomb kills also many birds each year.
