Movements and Behavior
Of the 15 species of crane, the Blue Crane has the most restricted distribution of all. Even species with lower population numbers now (such as Siberian or Whooping Cranes) are found over a considerable range in their migratory movements. The Blue Crane is migratory, primarily altitudinal, but details are little known.
The Blue Crane is partially social, less so during the breeding season. There is a strict hierarchy in groups, with the larger adult males being dominant. They overlap in range with 3 other crane species but interactions with these species and other "large wader" type birds are not known. They are relentlessly aggressive to various other animals during the nesting season, attacking non-predatory species such as cattle, tortoises, plovers and even sparrows. Humans are also attacked if they approach a nest too closely, with the aggressive male having torn clothes and drawn blood in such cases.

Famous quotes containing the words movements and/or behavior:
“In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary living—in this system of fine and finer, where then is the substance of a thought?”
—Doris Lessing (b. 1919)
“In abnormal times like our own, when institutions are changing rapidly in several directions at once and the traditional framework of society has broken down, it becomes more and more difficult to measure any type of behavior against any other.”
—John Dos Passos (1896–1970)
