Smith Oaks Bird Sanctuary is 177 acres of fields, woods, wetlands and ponds. Sixty-four acres were purchased by Houston Audubon with the help of Houston Audubon members, friends, and the National Fish and Wildlife Foundation. The remaining 110 acres were donated to Houston Audubon by Amoco Production Company. The Rookery in the middle of Claybottom Pond has become a favored roosting and nesting place for thousands of waterbirds. The sanctuary is open to the public sunrise to sunset year round. The High Island sanctuaries are fee sites. The fee helps defray the costs of maintenance, utilities and improvements for the entire Houston Audubon sanctuary system. A day pass costs $8, or for $30 a patch may be purchased which gives you an unlimited number of admissions to all High Island sanctuaries for one year.
