Evidence is presented supporting a seasonal segregation by sex and age of the Red-billed Quelea (Quelea quelea) in and associated with the Awash River Basin of Ethiopia. Sexual segregation is most pronounced in the late dry season/early rains period (March-June), which precedes breeding (July-September). At this time the males appear to be more concentrated in the middle Awash Valley, in the general area where breeding will occur, while the females remain more dispersed. A balanced sex ratio is found from July to September. Following breeding there is a general dispersal with many queleas moving out to the cereal growing areas that border the Awash Valley. This process of dispersal results in a separation of adults from juveniles and, to a lesser degree, males from females.
