Eos (genus) - Behaviour and Ecology

Behaviour and Ecology

The Eos lories feed on the nectar and pollen of various trees and plants. Very little is known about the diet of most species, but birds have been observed feeding on the flowers of coconuts, Eugenia, coral trees (Erythrina), Canarium, and sago palm (Metroxylon). In addition, they have been observed feeding on unripe fruits of fig trees (Ficus), and insects have been found in the stomachs of at least one species (the Red Lory). Some species are reported to be nomadic, moving between islands within their range in order to find food. These movements can apparently be daily as well, with the Violet-necked Lory making daily trips from its main islands to smaller offshore islands.

The Eos lories are apparently seasonal breeders, with birds prospecting for nesting sites varying by species, having been observed in June and July in the Black-winged Lory but August and September in the Red Lory. Like most parrots, they are cavity nesters, generally nesting high in older large trees either in forests or in modified habitats. Most of what is known about their nesting behaviour is derived from captive birds. They generally have a clutch size of two eggs which are incubated for 26–27 days. Chicks take around 75–87 days to fledge.
