Notes on the diet of the endemic red-eared parakeet pyrrhura hoematotis and other venezuelan montane parrots

Abstract:

Summary. Information on the diet of some species of tropical parrots is still scarce. We present data on the feeding ecology of the red-eared parakeet Pyrrhura hoematotis, an endemic and poorly known species of Venezuelan montane forests. Additionally, we describe other observations on the diet of the Venezuelan parakeet Pyrrhura emma, scarlet-fronted parakeet Psittacara wagleri and lilac-tailed parrotlet Touit batavicus. Red-eared parakeets used thirteen species of plants and their diet consisted principally of arillate seeds, but also included fleshy fruits and flowers. Tree species of Euphorbiaceae were main items in the diet of red-eared and scarlet-fronted parakeets. Leaves and resin of Clusia alata trees are reported for the first time in the diet of the lilac-tailed parrotlet. Our results add basic natural history data that can be useful for the conservation of these restricted distribution parrot species that are threatened by the habitat loss.
