Mate and nestling desertion in colonial little egrets
Little Egret (Egretta garzetta) Science Article 1 abstract I observed 25 Little Egret (Egretta garzetta) nests during the nestling period. Eleven (44%) were deserted by the female parent, one (4%) by the male, and three (12%) by both parents. Deserters of both sexes left nests soon after single parent care became feasible ([x bar] = […]

Evidence of prenuptial moult in the Little Bittern Ixobrychus minutus
Little Bittern (Ixobrychus minutus) Science Article 1 abstract Evidence for a partial prenuptial moult in the Little Bittern Ixobrychus minutus is reported for the first time, and is based on both live and museum specimens. The prenuptial moult, which is probably undertaken in the African winter quarters shortly before the spring migration, involves body feathers […]
