The relative frequency of Common Pigeons Columba livia in the diet of Peregrine Falcons differed across three areas of south-central Wales in line with racing pigeon availability. Peregrines exhibited a functional response to spatial and temporal availability of racing pigeons. During the pigeon-racing season (April–September), pigeons comprised 63% of kills in South Wales where pigeons were most available, 43% in the Brecon Beacons with intermediate availability and 30% in Central Wales, where availability was lowest. The corresponding values outside the pigeon-racing season were 18%, 6% and 5% respectively. We estimate that 92% of pigeons killed by Peregrines were racing pigeons, 7% were feral pigeons and the remainder were other domestic pigeon varieties.
