Leaf-slicing behavior in the Blue-headed Parrot (Pionus menstruus) in central Amazonia is likely linked to highly selective caterpillar predation
Although they eat seeds, pulp, petals, pollen, and nectar, parrots are rarely recorded as eating leaves, with only one species being fully folivorous. In terra firme forest in south-central Brazilian Amazonia, we recorded apparent folivory over a several sequential days by the Blue-headed Parrot (Pi...
