Dates of reproduction throughout Brazil are between October and December; however, the populations endemic to Sao Paulo and Rio de Janeiro both breed in November (Isler and Isler 1987). Brazilian Tanagers build an open cup nest made out of woven vines, grasses, and other fibers (Isler and Isler 1987). Nests are usually situated within bushes, low trees, or hidden within dense areas of marsh grass (Isler and Isler 1987). Eggs are usually laid in groups of 2-3 and are greenish blue with small black/gray markings (Isler and Isler 1987). There is no natural information of incubation, but in captivity the female incubated for thirteen days before the eggs hatched. After hatching the young were fed by both parents (Nørgaard-Olesen 1973). Shiny Cowbirds (Molothrus bonariensis) frequently brood parasitize Brazilian Tanagers (Sick 1993).
