The two subspecies show different breeding cycles due to their differing geographical distribution and seasonal climate variability. The breeding cycle is annual for R.f. flammigerus: it breeds only once in February, during the dry season (Isler and Isler 1987). R. f. icteronotus breeds at different times, depending on location: February to mid-May in Panama; nesting December to mid-April and eleven breeding-condition birds February to May in Colombia; fledged young with adult in early March in Ecuador. Four birds in breeding condition were also found in July in upper Cauca Valley (Hilty 2011).
The nest is a compact open cup of leaves and plant fibers, often with leaves and lichens on outside and 2-5 m up in a bush or low tree. A clutch is usually 2 eggs, occasionally 3 (Hilty and Brown 1986). Nestling period is 12-14 days (Nørgaard-Olesen 1973).
A cup nest of R. f. flammiferus was found in low weeds in Valle (Colombia) (Hilty and Brown 1986). Eggs are pale blue with dark spots or short lines, sometimes coalescing in a wreath about the large end (Isler and Isler 1987). Another open nest was found in Panama, cup-shaped and made of coiled roots mixed with pieces of dead leaves on the outside and finer, softer rootlets on the inner lining. The foundation under the nest was made of long slender roots of epiphytes up to 7 m long with mixed fragments of dried, dead leaves. It contained two eggs that measured 24.9x16.9 and 24.1x17.2 mm (Wetmore et al. 1984).
