The SPRNCA provides habitat for over 100 species of breeding birds. The San Pedro River is also a critical migration corridor that provides water, food, and shelter for another 250 migratory and wintering birds. Novice and experienced bird watchers attend our bird walks to view the diverse avian community of the area. We usually observe 30-60 species on these popular walks, which last approximately three hours. Bring water, hat and binoculars. These walks can be moderately difficult on uneven terrain. The San Pedro House is located 7 miles east of Sierra Vista on Highway 90, on the south side of the highway. It is searchable in Google Maps.
