Results showed that birds were the major prey both in frequency and in biomass. Besra Sparrowhawk preyed more on species active in canopy, mid-layer, and shrubs than on the ground. There were seasonal shifts in prey composition and diet diversity indices. We suggest that Besra Sparrowhawk captured prey opportunistically, capitalizing on seasonally emerging prey species that are abundant and energetically rewarding to catch. %M doi:10.6165/tai.2004.49(3).149
