Twelve years of research in SA's largest private game reserve has solved the mystery of why cooperation between birds is a notable feature of the world's most unpredictable environments.
“In this case, things are more complicated,” said lead researcher Pablo Capilla-Lasheras. “In this species co-operation is probably not explained by classical evolutionary theory because the presence of helpers does not increase the overall reproductive success of relatives.
“Bet-hedging strategies like this are all about reducing the risk of total failure when you can’t predict what is going to happen. The study found that female helpers were more co-operative - feeding chicks more - than male helpers.
