Examination of 1693 birds mist netted in the central Maryland Piedmont during the nesting season revealed 14% (n = 232) infested with immature Ixodes scapularis Say. Ticks were removed from 40% of bird species examined (19 of 47 species). Regular collection of ticks established a temporal record of immature tick stages over 2 nesting seasons. Among birds with at least some immature ticks, hatch-year birds had more (62% of the ticks) than adult birds (38%), and a higher proportion of hatch-year than adult birds were infested. There were no differences between male and female birds of any species. One new bird species host record for immature I. scapularis was recorded. There were 13 records of recaptured birds from which ticks had been removed, which were subsequently reinfested. Ten recaptured birds from which ticks had been removed were not reinfested. Small numbers of immature Haemaphysalis leporispalustris (Packard) and two I. muris Bishop and Smith were collected.
