Breeding

Breeding is thought to take place from July or August to January in Costa Rica (Stiles and Skutch 1989, Sánchez et al. 2000), and May to September in Colombia (Stiles 1999, and references therein).

A nest found in Costa Rica was bulky and cup-shaped, constructed on a branch with fibers and scales from tree ferns, with an outer lining of liverworts, mosses and lichens (Sánchez et al. 2000). The main structure comprised an outer layer of scales from the tree ferns Cyathea onusta and Sphaeropteris brunei and a thicker inner layer composed of fibers from C. onusta. The outside lining, comprised of liverworts identified as Taxilojeuna sp. and Frullania sp., the moss Meteorium illecebrum and lichen, was glued on with spider webs. Two tails of hanging liverworts draped beneath the nest on each side of the supporting branch. The outer cup measured 55.4-65.8 mm in height, with the depth of the inner cup measuring 28-33 mm. The outer cup diameter was 57 mm, with an inner cup diameter of 31 mm. Two whitish, elliptically-shaped eggs were laid in that nest. Other examples of the species' nests have been very similar (Sánchez et al. 2000). The nests documented by Sánchez et al. (2000) were located c.2-6 m from the ground in primary forest and secondary growth.
