Terrestrial foraging by cacajao melanocephalus ouakary (primates) in Amazonian Brazil: Is choice of seed patch size and position related to predation risk?

We analyse the behaviour of Cacajao melanocephalus ouakary feeding at patches of germinating seedlings in dried-out flooded forest. Seedlings of Eschweilera tenuifolia (Lecythidaceae) were the most commonly eaten (88.9%). Some seed patches were revisited over several days, while others were consiste...
