The breeding season extends from January to August (Raffaele 1989, Pérez-Rivera 1993), but mating has been observed during November at Maricao State Forest (A. Morales personal observations). The nest is cup-shaped (Gundlach 1982, Pérez-Rivera 1993) with substantial walls. Both sexes participate in carrying nesting material, although the female does most of the construction (Pérez-Rivera 1993). Nest construction materials are vines, roots of epiphytes, fibers of sierra palm (Prestoea montana) leaves, fungal hyphae of Marasimus sp., which are used to sew the nest, and the stems and leaves of Micrograma and Gramnintis ferns. The nest is lined with sierra palm leaves and sometimes downy tanager feathers. The nest is located in the distal end of a branch and usually covered with vines. Height of the nest varies from 2-10 ms above ground (Pérez-Rivera 1993). Average nest dimensions: outside height 6.5 cm, depth of cup 4.6 cm, outside diameter 9.2 cm, and diameter of cup 7.4 cm. The clutch is 2-3 whitish sub-elliptical eggs, boldly scribbled or scrawled, with reddish to dark brown blotches and spots. Egg size averages 23.6 x 17.3 mm (n = 3) from one clutch (Pérez-Rivera 1993).
