Family Proctophyllodidae—proctophyllodid feather mites*

Proctophyllodid mites are often very numerous on the flight feathers of passeriform birds and hummingbirds. Host specificity is variable. Like most wing­inhabiting feather mites, they feed on preening oil, fungi, and other debris on the feathers. There are many undescribed species in North America. Gaud & Atyeo (1996) stated that, unlike the situation in most other groups of feather mites, proctophyllodid genera often occur on a particular bird species (or a group of species) as single species (i.e., multi­species associations on a single host species are rare). All of the following entries for proctophyllodids represent new records for the Park.
