When fruit resources in tropical forests are scarce, frugivorous birds might track fruiting by expanding their home-ranges or by moving. We tested whether the abundance of the Yellow-legged Thrush (Turdus flavipes) and White-necked Thrush (T. albicollis) is correlated with the fruiting of the domina...
