San Bernard National Wildlife Refuge Professional Review and Guide
"Grassland, marsh, and woodland combine to offer good year-round birding at this coastal refuge just southwest of Freeport, managed by the same U.S.Fish and Wildlife Service team that oversees Brazoria NWR, a dozen miles northeast. The 27,414-acre refuge (much of it not accessible to the public) offers several opportunities for exploration.
You’ll see a lot simply driving the auto-tour route. Waders of more than a dozen species (including Roseate Spoonbill) are always present, and Wood Storks arrive in numbers in summer and early fall. In winter, tens of thousands of Snow Geese make their home here, with lesser numbers of Greater White-fronted, Ross’s, and Canada geese. Sandhill Cranes are also common winter visitors."
