Swallow-tailed Hummingbird (Campylopterus macroura) Science Article 1
An August or winter nestling of Eupetomena macroura was fed only every 40-50 min for at least 24days in the nest, with fewer feedings at midday. As in other hummingbirds, it was brooded only thefirst week or two, and left alone even on cool nights after 12 days, probably due to the small nestsize. The female attacked birds of many non-nectarivore species near the nest, in part probably toavoid predation. Botfly parasitism was extremely high, as in some other forest-edge birds.
