Alcedoffula alcyonae Carriker (Phthiraptera: Ischnocera: Philopteridae) infesting belted kingfisher, Megaceryle alcyon (Linnaeus) (Aves: Coraciiformes, Alcedinidae), in Manitoba, Canada

Abstract

Forty-one belted kingfishers, Megaceryle alcyon (Linnaeus) (Aves: Coraciiformes: Alcedinidae), from Manitoba, Canada were examined for ectoparasites in 1995–2020. One species of chewing louse, Alcedoffula alcyonae Carriker (Phthiraptera: Ischnocera: Philopteridae), infested 48.8% of hosts. The mean intensity of infestation was 17.1, and mean abundance was 8.5 lice per bird. Distribution of infestation was highly aggregated. Although female lice outnumbered males, the sex ratio was not significantly different from 1.0. The ratio of nymphs to females was 2.6. An unidentified species of feather mite of the genus Proterothrix Gaud (Acari: Astigmatina: Proctophyllodidae) infested three of 35 hosts (8.6%). No mites were found in the quills of primary feathers from 19 birds, and no nasal mites were collected from 32.
