Between 30 April and 26 June 2004, I found Yellow-billed Stork breeding at three waterbird colonies ineasternUganda. Onecolonywaslocatedby therailway quarters in Mbale town (01°N, 34°E), one in the hospital grounds at Busolwe (00°N, 33°E) and one near the trading centre at Nampologoma (00°N, 34°E). A The number ofbreeding pairs ofYellow-billed Stork varied at each colony. maximumof129pairswererecordedatBusolwe,26pairsattheMbalecolony and 4 pairs at Nampologoma. Five other bird species, African Spoonbill Platalea alba, Black-headed Heron Ardea melanocephala, Cattle Egret Bubulcus ibis, Pink-backed Pelican Pelecanus rufescens and Sacred Ibis Threskiornis aethiopicus were also found breeding at these colonies (Table 1).
