No lice were found infesting barn owl (Tyto alba (Scopoli); Aves: Tytonidae) or eastern screech owl (Megascops asio (Linnaeus); Aves: Strigidae). We collected a total of 113 810 lice of 12 species: Kurodaia Uchida (Phthiraptera: Menoponidae) &amp;ndash; three species; and Strigiphilus Mj&amp;ouml;berg (Phthiraptera: Philopteridae) &amp;ndash; nine species. Overall prevalence of infestation ranged from 10.0% to 88.9%. Mean intensity for total lice ranged from 22.4 to 506.5. Infestation parameters for each louse&amp;ndash;host combination are provided; prevalence and mean intensity were not related for louse&amp;ndash;host species combinations. Distribution of louse infestations was highly aggregated. In all louse&amp;ndash;host combinations but one, either females were more prevalent than males or there was no significant deviation from 50:50. Male Strigiphilus ceblebrachys Denny significantly outnumbered females in snowy owls. There was a tendency for louse species to co-occur on the same host specimen. Where sample sizes for owls were large enough, no seasonal patterns in abundance of lice were detected.&lt;/p&gt;
