A total of 733 bird nests, representing 55 species from 23 habitats, was examined. Forty-nine percent of the nests of 39 bird species were infested with 16 species of Protocalliphora.

Infestation of bird nests by Protocalliphora is believed to be related to a number of factors, which are discussed. Loosely constructed nests, nests heavily saturated with feces, and nests occupied early in the season had low rates of infestation. Nests of colonial birds were more frequently infested than those of solitary birds. Nests of some birds were rarely or never infested.

Sixteen species of Protocalliphora are differentiated and their …
