Description
The nomenclature is that of the Fourth Edition of the American Ornithologists’ Union Check-list and its supplements, except where a revision has been made that is seemingly valid but which has not yet been acted upon by the A. O. U. Committee. For each species or subspecies the objective is to give at least one reference to occurrence, as to date and place, as accurately as possible. Reference is made to southern, central, and northern Idaho.
