Abstract
During the unusually extended breeding season of 1984/85 in Tsavo-East National Park, Kenya, Quelea quelea were sampled and moult patterns recorded. Particular attention was paid to individuals with an interrupted moult pattern. These were further classified as either having their moult arrested or suspended. Apparently, post-nuptial moult begins earlier in males than in females. Although the majority of quelea bred and moulted sequentially, these activities overlapped in many individuals and moulting suspended after the replacement of a few feathers. The initiation of post-nuptial moult before the cessation of breeding, followed by moult interruption, is evidence for the physio-ecological drive in quelea to complete their moult as soon as possible to prepare for the next breeding opportunity.
