Breeding

Four nests are described in the literature, one in Rondonia, Brazil, and three in central French Guiana. All nests were observed to be active in the wet season. Of these, only two nests in French Guiana were observed at close range, and in neither case was there a nest structure constructed by the birds; rather the offspring were placed directly on large epiphytic bromeliads (Aechmea spp.). The bromeliads were 45 and 40 m in height in 2008 and 2009 respectively. In 2008, the observed nest contained one partially feathered offspring of unknown sex, and in 2009 the nest contained a single egg. This egg hatched on 28 March 2009, and the offspring was recorded with a video camera until 18 April 2009 (McCann et al. 2010).

McCann  The offspring were provisioned by multiple adults, and in 2009 at least six adult plumage birds provided food to the chick. The majority of items brought to the chicks were wasp nests or fragments thereof, followed by large Spirostreptid millipedes, fruits, small unidentified items, and one snail. Of four marked individuals in the 2009 group of six or seven, two were female and two were male. The females provided 7 and 9 items respectively, and the two males 57 and 22 items (McCann et. al 2010).

Overnight egg incubation and brooding of the chick in 2009 was performed exclusively by a single female (McCann et al. 2010).
