Breeding of Yellow-browed Tody-Flycatcher is reported in June in Colombia (Hilty and Brown 1986), in April and in July in eastern Ecuador (Hilty and Brown 1986, Greeney et al. 2004), and in November in eastern Brazil (Pinto 1953).
The nest is a pendant globular structure, and is sited from 4-35 m above the ground (Hilty and Brown 1986, Greeney et al. 2004). Both sexes contribute to nest construction (Greeney et al. 2004). Two nests in Ecuador were located in the same tree, and both within a meter of a paper wasp nest (Vespidae) (Greeney et al. 2004).
The clutch apparently is two. Egg dimensions are 15-16 mm x 11-12 mm (Pinto 1953). Nothing in nothing about the length of incubation or of development of the nestlings.
