Barn owl Tyto alba pellets were collected regularly at a roost in a maize loft on the farm Sandfontein, 8 km east of Warmbaths, Transvaal. The farm embraces a mosaic of Acacia and Combretum woodland. The roosting site was not used for nesting during the time that pellets were collected, though it has been used for breeding in the past (P. Rissik: pers. comm.). The loft is situated near the homestead bordering open cattle paddocks with some big trees, mostly Sclerocarya birrea and Acacia tortilis.
