Neo-tropical Migrants of the Spring-fed Arroyo:
These species breed here in the summer or pass through during migration to breeding grounds further north. They spend the winter south of the Tropic of Cancer. (For this work, I have included some species that vacate our area, but go only as far south as southern US and/or northern Mexico.)
(All of these species are protected under the Neotropical Migratory Bird Conservation Act - NMBCA. See Complete NMBCA list.
