Editing Blue crane (section)

==Movements and behaviour==
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 crane|Siberian]] or [[whooping crane]]s) 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 three other crane species but interactions with these species and other [[Wader (American)|"large wader" type birds]] are not known. They are aggressively protective of their nesting sites during the nesting season, even attacking innocent, non-predatory animals such as antelope, cattle, [[tortoise]]s, [[plover]]s and the smallest of birds, such as [[Old World sparrow|sparrow]]s. Humans are also attacked if they approach a nest too closely, with the aggressive male having torn clothes and drawn blood in such cases. Threats to their eggs and chicks include large [[savannah monitor|savannah]] and [[white-throated monitor]] lizards, [[Egg-eating snake (disambiguation)|egg-eating snake]]s, [[fox]]es, [[jackal]]s, birds-of-prey, [[meerkat]]s, and [[mongoose]].
