Savanna Habitat Drives Birds, and Perhaps Others, to Cooperative Breeding
August 16, 2007
Birds of a feather flock together, but for African starlings, this is true primarily in savannas, where cooperation improves survival in the unpredictable habitat, according to UC-Berkeley and Cornell researchers. Cooperative breeding, where helpers forego breeding to gather food for the offspring of other group members, seems to be a successful survival strategy with the highly variable rainfall of the savanna. Savanna habitats may have led to cooperative social behavior in other species also.
