Breeding

Brood parasitic. Details of breeding biology little known except for a short list of known host species that build hanging globular nests (based on Sick 1953a, 1993, Makatsch 1971, Sanchez-Martinez et al. 2017, see also Payne 2005): Sepia-capped Flycatcher Leptopogon amaurocephalus, Slaty-capped Flycatcher Leptopogon superciliaris, Ochre-bellied Flycatcher Mionectes oleagineus, Drab-breasted Pygmy-Tyrant (Hemitriccus diops), Ochre-faced Tody-Flycatcher Poecilotriccus plumbeiceps), Eared Pygmy-Tyrant (Myiornis auricularis), and Plain Antvireo (Dysithamnus mentalis). As is true for all brood parasitic species, parental care of eggs and young provided by host species. Egg rose white with purple spots; 21 x 15 mm (Giai 1949, Neunteufel 1951, Sick 1953a, 1953b, Payne 2005). Length of incubation period and details of nestling appearance, growth and behavior little known. Nestling cuckoos apparently eject host eggs and kill host young; nestling period 24 days (n = 1; Sanchez-Martinez et al. 2017).
