Breeding

Few nests of Fawn-breasted Tanager have been reported. A nest studied in Veneuzela was discovered in May (Alquezar et al. 2010). Birds in breeding condition were reported from Colombia in March and July (Hilty and Brown 1986), with a breeding condition male (testis 7 mm) singing from the top of a tree in a bushy pasture (Miller 1963. Nest construction in southwestern Ecuador was noted in the period from late January to early March (Best et al. 1996). Additionally, fledglings have been observed in July in Mérida, with juveniles observed in July and August in Junín, Peru (Fjeldå and Krabbe 1990). Nests in southern Brazil are reported from September and October (Belton 1985). The mossy nests are typically high and concealed in moss and epiphytes along horizontal branches (Belon 1985, Isler and Isler 1987, Alquezar et al. 2010). The only nest described in detail was cup shaped with a diameter of about 7-9 cm (Alquezar et al. 2010). The clutch size is 2, with incubation lasting 12-14 days, and the young remaining in the nest and cared for by both parents for 18-22 days before fledging (Alquezar et al. 2010).
