For those of you who are fuzzy on the meanings of the English words, gophers and moles live underground. Moles are blind, gophers are not. The little animal in the Caddyshack movie is a gopher. Squirrels generally live in trees, though here in Southern California there are a tremendous number of ground squirrels that live underground, and they are somewhat different from tree squirrels. They are not the same as gophers.
My workers use topo for both gophers and moles. Ardilla means squirrel to them, regardless of whether the squirrel lives in a tree or underground. The online dictionaries say that a topo is a mole, and that a gopher is an ardilla de tierra, which to me means ground squirrel.
Anyone have any different regional words for these pests?
