Cranes are large, long-legged and long-necked birds. Cranes like many other aquatic species are indicators of the state of the environment. When we stop seeing cranes , it means there are no more wet lands , an ecosystem crucial to the survival of the birds. In Kenya Lake Ol Bolossat, a pretty lake on the foothills of the Aberdare ranges in central Kenya is home to about 900 Grey Crowned Cranes. During the breeding season between July and February, hundreds of cranes flock here and put on a spectacular view of courtship dances.
