Breeding

Breeding of Black-capped Pygmy-Tyrant is reported from March-May in Costa Rica (Stiles and Skutch 1989). Nests have been found in Panama in March and April (Wetmore 1972, Willis and Eisenmann 1979). Specimens in breeding condition are reported from western Colombia from February to May, and a fledgling, still being feed by adults, was observed in that region in March (Hilty and Brown 1986).

Nests are long and pendant, with a round side entrance (Wetmore 1972, Willis and Eisenmann 1979, Stiles and Skutch 1989, Robinson et al. 2000). Nests are supported by twigs or leaf petioles and are constructed 1.3-7.3 meters above the forest floor (Wetmore 1972, Willis and Eisenmann 1979, Stiles and Skutch 1989). The nest is composed of mosses and liverworts, while the chamber is lined with fine fibers (Wetmore 1972, Stiles and Skutch 1989). The dimensions of one nest were ca 150 mm long and 90 mm wide (Wetmore 1972).

The clutch is two; the eggs are whie, marked with cinnamon or pale brown (Wetmore 1972m Stiles and Skutch 1989, Pereira et al. 2004).

Robinson et al. (2000) reported one fledged chick during a nesting success study in central Panama.
