What type of food does a green honeycreeper eat?

Fruit, insects and nectar are what a honeycreeper consumes.

Specifically, the bird in question (Chlorophanes spp) drinks nectar from wild flowers. The bird is one of four species that altogether range southward from Mexico all the way into Brazil and southeastward onto the Caribbean island of Trinidad. Honeycreepers also relish the fruit and the insects that are available within the forest canopy.
