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:
“The movements of the eyes express the perpetual and unconscious courtesy of the parties.”
—Henry David Thoreau (1817–1862)
“This whole business of Trade gives me to pause and think, as it constitutes false relations between men; inasmuch as I am prone to count myself relieved of any responsibility to behave well and nobly to that person who I pay with money, whereas if I had not that commodity, I should be put on my good behavior in all companies, and man would be a benefactor to man, as being himself his only certificate that he had a right to those aids and services which each asked of the other.”
—Ralph Waldo Emerson (1803–1882)
