Two nighthawks were infested with the rabbit tick, Haemaphysalis leporispalustris (Packard), and 64 (62.1%) with the chewing louse, Mulcticola macrocephalus (Kellogg), at a mean intensity of 13.5. Louse infestation fits a negative binomial distribution (k=0.299; mean/variance ratio=18.5); females outnumbered males in the total sample, males:females=0.66. Prevalence of infestation was lower in adult birds examined during May and June (37.5%; n=16) than in mixed&ndash;age birds examined from 31 July to December (64.7%; n=85), though mean intensity was similar (17.7 versus 13.6, respectively). Two of seven Whip&ndash;poor&ndash;wills were infested with an undescribed Mulcticola sp.</p>
