Smith Oaks Bird Sanctuary is 177 acres of fields, woods, wetlands and ponds. 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, including Smith Oaks, are fee sites–$8 for a day pass and $30 for a season pass. Income supports the habitat restoration efforts conducted by Houston Audubon.
