Free downloading pics of sandhill cranes gallery






The sandhill crane (Grus canadensis) is a species of large crane of North America and extreme northeastern Siberia.This is the most important stopover area for the nominotypical subspecies, the lesser sandhill crane (Grus canadensis canadensis), with up to 450,000 of these birds migrating through annually.The average weight of the larger males is 4.57 kg (10.1 lb), while the average weight of females is 4.02 kg (8.9 lb), with a range of 2.7 to 6.7 kg (6.0 to 14.8 lb) across the subspecies.Sandhill cranes have red foreheads, white cheeks and long dark pointed bills. In flighing, their long dark legs trail behind, and their long necks keep straight. Immature birds have reddish brown upperparts and gray underparts.The both male and female look alike sizes vary among the different subspecies, the average height of these birds is around 80 to 122 cm (2 ft 7 in to 4 ft 0 in).Their wing chords are typically 41.8–60 cm (16.5–23.6 in), tails are 10–26.4 cm (3.9–10.4 in), the exposed culmens are 6.9–16 cm (2.7–6.3 in) long and the tarsi measure 15.5–26.6 cm (6.1–10.5 in).These cranes frequently give a loud trumpeting call that suggests a French-style "r" rolled in the throat, and they can be heard from a long distance.The cranes stand close together, calling in a synchronized and complex duet. The female makes two calls for every one from the male.

sandhill cranes are large wingspans, typically 1.65 to 2.29 m (5 ft 5 in to 7 ft 6 in), make them very skilled soaring birds, similar in style to hawks and eagles. Utilizing thermals to obtain lift, they can stay aloft for many hours, requiring only occasional flapping of their wings and consequently expending little energy.Sandhill cranes are mainly herbivorous, but eat various types of food, depending on availability. They often feed with their bills down to the ground as they root around for seeds and other foods, in shallow wetlands with vegetation or various upland habitats. Cranes readily eat cultivated foods such as corn, wheat and sorghum. Waste corn is useful to cranes preparing for migration, providing them with nutrients for the long journey. Among northern races of sandhill cranes, the diet is most varied, especially among breeding birds. They variously feed on berries, small mammals, insects, snails, reptiles and amphibians.This crane nest sites are usually marshes, bogs or swales, though occasionally on dry land. Females lay one to three (usually two) oval, dull brown eggs with reddish markings. Both parents incubate the eggs for about 30 days. The chicks are precocial; they hatch covered in down, with their eyes open and able to leave the nest within a day. The parents brood the chicks for up to three weeks after hatching, feeding them intensively for the first few weeks, then gradually less frequently until they reach independence at nine or ten months old.for different pics....
