Honeycreepers of the Americas, although they look a little like the Sunbirds of Africa/Asia, are related to Tanagers rather than Sunbirds/Hummingbirds/Honeyeaters.
The Red-legged Honeycreeper comes from southern Mexico, Central America, the Caribbean and northern South America.
The female, like Sunbirds, is a mottled grey. The male, however, only has his beautiful mauve and turquoise suit in the breeding season and then moults to resemble the grey female.
As the shape of the bill indicates, Honeycreepers are nectar feeders, but they also take fruit, seeds and insects. The male's under-wing is pale yellow.
