Abstract
A total of 4781 nests of 110 species of birds was examined for the pre sence of Protocalliphora in several localities in Ontario, Canada, and the intermountain region of northern Utah. Twenty species belonging t o this genus were found in 1621 (33.8%) nests of 73 avian species. Som e species, such as P. chrysorrhoea and P. halli, showed strong host pr eferences, whereas others, such as P. metallica and P. interrupta, pre ferred specific nest environments. The nests of birds that live in col onies and (or) return to the same site annually were more frequently a nd heavily infested than those of other birds. In Utah, where 17 speci es of Protocalliphora occurred, most species showed a degree of host p reference, whereas in Ontario, where there were only 9 species, most s pecies preferred specific nest sites. Of the 20 species of Protocallip hora collected during this study, 3 were found exclusively in Ontario and 11 in Utah, with 6 species common to both study areas.
