The breeding season in the Arima valley of Trinidad peaks between January and May, which is highly coincident with the flowering peaks of Heliconia and Pachystachys. Green Hermit breeds February-September in Costa Rica (Stiles and Skutch 1989). Nests also have been reported in Colombia in August (Snow and Snow 1980).
Nesting sites are in Heliconia, ferns, or palms, 0.6-4.6 m above the ground, and often overhanging or near or overhanging streams (Snow 1974, ffrench 1991). Nests are cone-shaped and affixed to the underside of the tip of a free-hanging leaf by cobwebs. The nest itself is composed of soft plant fibers and vegetative down, and lined with seed-plumes. The clutch size is two eggs, with an incubation period of 17-18 days. Males do not share incubation or feeding duties (Snow 1974).
