Abstract
We monitored 25 Besra Sparrowhawk (Accipiter virgatus) nests from 1993 to 2002 in
Yangmingshan, northern Taiwan, to document the prey composition of this species during the
breeding season. 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.
