DISTANCES OF MIGRATION VARY
Definite evidence shows that both the length and the duration of the migratory journey vary greatly. The bobwhite and the western quails, the cardinal (Richmondena cardinalis), the Carolina wren (Thryothorus ludovicianus), and probably some of the titmice and woodpeckers, which are apparently nonmigratory, may round out their full period of existence without at any time going more than 10 miles from the nest where they were hatched.
