The claim that they will remove ticks and other parasites from grazing animals has been disputed; while there is no doubt that anis follow grazing animals to catch disturbed insects and will occasionally eat fallen ticks, there is no proof that they remove ticks from the animals' bodies.

'' to accommodate a single species, the smooth-billed ani (''Crotophaga ani''). The genus name combines the Ancient Greek ''krotōn'' meaning "tick" with ''-phagos'' meaning "-eating". Linnaeus cited the Irish physician Patrick Browne who in 1756 in his ''The Civil and Natural History of Jamaica'' had used the name ''Crotophaga'' and remarked that smooth-billed anis "live chiefly upon ticks and other small vermin; and may be frequently seen jumping about all cows and oxen in the fields". The name "Ani" was used in 1648 by German naturalist Georg Marcgrave in his '' Historia Naturalis Brasiliae''. Marcgrave did not explain the origin of the word, but it is probably derived from the Tupi language.
