Social Flycatcher Myiozetetes similis



Del Hoyo et al. found that the breeding season of Social Flycatchers is February through June in Costa Rica and May through July in Venezuela (2004). Nesting-building has been observed in January, March and April in Colombia (del Hoyo et al. 2004). Egg laying generally takes place between March and April in Panama, however, a study conducted by Dyrcz found that egg laying can begin as early as the beginning of February (del Hoyo et al. 2004, 2002). In Peru, nests have been found in August through January, suggesting possible display behavior (del Hoyo et al. 2004).

Nest building as described by del Hoyo et al (2004):
Social Flycatcher nest building is done by the female. Large, bulky, domed nests are constructed using dried grass, straw, weed stems, twigs, cotton, paper, and pieces of plastic. Nests are built in very obvious places, often over water or in man-made structures. Social Flycatchers will also often utilize nests of other birds as a foundation for their nests. Clutch sizes range from 2-4 eggs that have a creamy or pinkish coloration (Stiles and Skutch 1989). Incubation is done by the female for 15-16 days and fledging occurs at 17-21 days. In Panama, it was found that 68% of nests are lost to predation. Annually, a pair of Social Flycatchers will raise one brood; however, they may lay up to five nests in a season due to predation.
