The whooping crane (Grus americana) is an endangered crane species, native to North America, [3] [1] named for its "whooping" calls. Along with the sandhill crane ( Antigone canadensis ), it is one of only two crane species native to North America, and it is also the tallest North American bird species. [ 3 ]
The species with the smallest estimated population is the whooping crane, which is conservatively thought to number 50–249 mature individuals, [5] and the one with the largest is the sandhill crane, which has an estimated population of 450,000–550,000 mature individuals.
Of the four crane genera, Balearica (two species) is restricted to Africa, and Leucogeranus (one species) is restricted to Asia; the other two genera, Grus (including Anthropoides and Bugeranus) and Antigone, are both widespread. [5] [1] Many species of cranes are dependent on wetlands and grasslands, and most species nest in shallow wetlands.
However, North America's other crane species, the whooping crane, is endangered. Only about 80-to-85 whooping cranes currently live in Wisconsin, Lacy said. Only about 80-to-85 whooping cranes ...
Gruiform means "crane-like". Traditionally, a number of wading and terrestrial bird families that did not seem to belong to any other order were classified together as Gruiformes. These include 15 species of large cranes , about 145 species of smaller crakes and rails , as well as a variety of families comprising one to three species , such as ...
The greater sandhill crane proper initially suffered most; by 1940, probably fewer than 1,000 birds remained. Populations have since increased greatly again. At nearly 100,000, they are still fewer than the lesser sandhill crane, which, at about 400,000 individuals continent-wide, is the most plentiful extant crane. [26] [40]
