Seasonal food habits and prey selection of Amur tigers and Amur leopards in Northeast China

Abstract We analyzed the scats of Amur tigers and Amur leopards, and examined their annual and seasonal food habits in Northeast China to comprehend their coexistence. Wild boar had the highest annual and seasonal consumption frequencies by the tigers, while both roe deer and sika deer were mostly p...
