The bird genus Balearica (also called the crowned cranes or Balearic cranes) contains two extant species in the crane family Gruidae: the black crowned crane (B. pavonina) and the grey crowned crane (B. regulorum). [2] The species today occur only in Africa, south of the Sahara Desert, and are the only cranes that can nest in trees.
Cranes are very large birds, often considered the world's tallest flying birds. They range in size from the demoiselle crane, which measures 90 cm (35 in) in length, to the sarus crane, which can be up to 176 cm (69 in), although the heaviest is the red-crowned crane, which can weigh 12 kg (26 lb) prior to migrating.
Grey crowned crane (Balearica regulorum) Some authorities use the term "crowned crane" to refer generally to the genus Balearica. [1] Likewise, the International Ornithological Committee, who standardize common species names, have also used the group name "crowned crane" in the common names of the extant species of the genus Balearica.
