Behaviour and ecology

Breeding

In Costa Rica red-legged honeycreepers generally breed between April and June. The nest is built entirely by the female and is placed in a shrub or tree several meters above the ground. The cup-shaped nest has thin side walls and is formed of stiff fibres. It is attached to the supporting twigs with cobwebs. The clutch consists of two eggs that are laid in early morning on consecutive days. They are in size and have a white background with brown speckles forming a ring around the larger end. The female incubates the eggs for 12 or 13 days. When they first hatch the nestlings have their eyes closed and are covered with tuffs of grey down. They are brooded by the female but fed by both parents. They fledge after around 14 days. A specimen studied in the Parque Nacional de La Macarena of
