摘要：This study was conducted on Holla Bend National Wildlife Refuge in west-central Arkansas to investigate the food habits of the common barn owl (Tyto alba). Three hundred thirty-eight pellets were collected from four barn owl nest boxes yielding the remains of 1003 individual prey items. Hispid cotton rats (Sigmodon hispidus) were eaten most frequently, comprising 46.8% of the diet by frequency. Results of this study are compared with those from other Arkansas ecoregions to assess regional variation in the diet of this endangered species.
