Florida Sandhill Crane

Grus canadensis pratensis

Description:

Florida Sandhill Crane (Grus canadensis pratensis) - subspecies of Sandhill Crane (Grus canadensis) - near Viera Wetlands, Florida. << Florida Sandhill Crane, Grus canadensis pratensis – ESA: Endangered --- The Florida Sandhill Crane is far less common, with some 5,000 individuals remaining. They are most threatened by habitat destruction and probably depend on human management in the long run. In Florida, it is protected, and if killed, carries a very high monetary penalty. This subspecies is under protection of state and federal law at this time. Since the loss of habitat is a somewhat controllable cause of a declining population, habitat preservation is a valuable management measure. The current outlook for the Florida sandhill crane, if it can be maintained on the protected habitats, is good. Transplanting wild birds, as well as introducing captive-reared birds into suitable areas where crane numbers are low, appears to be a viable technique in the management of this threatened species. It is hoped that these management strategies, plus continued ecological research, will prevent the Florida sandhill crane from reaching a more critical status. >> (credit: http://en.wikipedia.org/wiki/Sandhill_Cr...)

Habitat:

The Sandhill Crane (Grus canadensis) is a large crane of North America and extreme northeastern Siberia. The common name of this bird references habitat like that at the Platte River, on the edge of Nebraska's Sandhills in the American Midwest. This is the most important stopover area for the Lesser Sandhill Crane (Grus canadensis canadensis), with up to 450,000 of these birds migrating through annually. Adults are gray overall; during breeding, the plumage is usually much worn and stained, particularly in the migratory populations, and looks nearly ochre. The average weight of the larger male 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 15 lb) across the subspecies. The Sandhill Crane has a red forehead, white cheeks and a long dark pointed bill. Its long dark legs trail behind in flight, and the long neck is kept straight in flight. Immature birds have reddish brown upperparts and gray underparts. The sexes look alike. Size varies among the different subspecies. This crane frequently gives a loud trumpeting call that suggests a French-style "r" rolled in the throat, and they can be heard from a long distance. Mated pairs of cranes engage in "unison calling." The cranes stand close together, calling in a synchronized and complex duet. The female makes two calls for every single call of the male. The sandhill crane's large wingspan, typically 1.65 to 2.1 m (5.4 to 6.9 ft), makes this a very skilled soaring bird 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. With migratory flocks containing hundreds of birds, they can create clear outlines of the normally invisible rising columns of air (thermals) that they ride. The Sandhill Crane flies south for the winter. In their wintering areas they form flocks of over 10,000 birds. One place to observe this is at Bosque del Apache National Wildlife Refuge, 100 miles south of Albuquerque, New Mexico. There is an annual Sandhill Crane Festival in November. Three subspecies are resident; pulla of the Gulf Coast of the U.S., pratensis of Florida and Georgia and nesiotes of Cuba.[10] The northern populations exist as fragmented remains in the contiguous U.S. and a large and contiguous population from Canada to Beringia. These migrate to the southwestern United States and Mexico. This crane is a rare vagrant to China, South Korea and Japan and a very rare vagrant to western Europe. Six subspecies have been recognized in recent times: Lesser Sandhill Crane, Grus canadensis canadensis Cuban Sandhill Crane, Grus canadensis nesiotes – ESA: Endangered Florida Sandhill Crane, Grus canadensis pratensis – ESA: Endangered Mississippi Sandhill Crane, Grus canadensis pulla – ESA: Endangered Canadian Sandhill Crane, Grus canadensis rowani Greater Sandhill Crane, Grus canadensis tabida Though the Sandhill Crane is not considered threatened as a species, the three southernmost subspecies are quite rare. While the migratory birds could at least choose secure breeding habitat, the resident populations could not, and many subpopulations were destroyed by hunting or habitat change. However, initially the Greater Sandhill crane proper suffered most from persecution; by 1940 probably fewer than 1,000 birds remained. They have since increased greatly again, though with nearly 100,000 individuals they are still less plentiful than the Lesser Sandhill Crane, which numbers over 400,000 individuals, making the species the most plentiful crane alive today. The Florida Sandhill Crane is far less common, with some 5,000 individuals remaining. They are most threatened by habitat destruction and probably depend on human management in the long run. In Florida, it is protected, and if killed, carries a very high monetary penalty. This subspecies is under protection of state and federal law at this time. Since the loss of habitat is a somewhat controllable cause of a declining population, habitat preservation is a valuable management measure. The current outlook for the Florida sandhill crane, if it can be maintained on the protected habitats, is good. Transplanting wild birds, as well as introducing captive-reared birds into suitable areas where crane numbers are low, appears to be a viable technique in the management of this threatened species. It is hoped that these management strategies, plus continued ecological research, will prevent the Florida sandhill crane from reaching a more critical status.
