The goal of this study was to identify feather mites on Cerrado birds. This study was conducted at Fazenda Água Limpa (FAL), Distrito Federal, Brazil, between January and August 2002. Birds were captured with mist nets and banded. Were sampled 696 birds, belonging to 83 species and 25 bird families of Passeriformes and non-Passeriformes. Feather mites were found on five families: Analgidae, Trouessartiidae, Proctophyllodidae, Avenzoariidae and Psoroptoididae. The present work reports new occurrences of feather mites on captured hosts. The family Proctophyllodidae and the genus Pterodectes were the most prevalent group of feather mites collected. Tyrannidae, Pipridae, Emberizidae and Thraupidae were the bird families with most host numbers, with parasites from three taxa: Trouessartiidae, Proctophyllodidae and Analgidae. Considering the birds captured the prevalence was 44.98%. Trochilidae, Conopophagidae, Furnariidae, Tityridae, Turdidae, Mimidae, Cardinalidae, and Parulidae were the families with major feather mites prevalence (>50%).
