  • a Species with at least one infested individual are shown (3,844 individuals of 85 species screened). Bird species were categorized according to foraging height during migration (ground, understory, and canopy/subcanopy) and whether their winter range was south of the Gulf of Mexico or included the study region (intercontinental migrant or local, respectively). We further categorized migrants on the extent of their wintering range (Central America and the Caribbean, Central and South America and the Caribbean, or South America). We captured one infested vagrant species from Central America that does not normally occur in Texas.

  • c Stationary nonbreeding range described as local (L) or migrant (M). C, Central America and the Caribbean; C/S, Central and South America and the Caribbean; S, South America; V, vagrant from Central America.

  • d An additional 698 individuals of 49 species were sampled for ticks and were not infested.
