Résumé :	Capsule Variation in prey availability appears to influence Chough fledging success and juvenile survival. Aims To determine seasonal and annual variations in Chough prey and how these influence fledging success and juvenile survival. Methods Chough faeces (n = 437, 3905 invertebrates) were collected year-round and analysed to determine diet composition. Seasonal and annual variation in prey abundance in Chough foraging habitat was assessed using pitfall trapping (n = 747, 27 124 invertebrates) between 1996 and 2003. Fledging success was estimated for a population of 12 breeding pairs; juvenile survival was estimated by year-round resighting (n
