42. Riviera Pothole Region, Riviera, Texas

Find waterfowl, rails, cranes, spoonbills, caracaras and many more birds in this mosaic of ponds and wetlands 60 miles south of Corpus Christi.

Don’t miss the prairie potholes of Riviera, Texas. Thousands of birders, many from around the world, come to the area to follow the Great Texas Coastal Birding Trail, but few are aware of the excellent birding at the diverse freshwater wetland habitats nearby.

The species-rich potholes dot a region of sandy hills and swales from Riviera to Baffin Bay in the highly saline upper Laguna Madre. The area reminds me of the prairie potholes of the northern U.S. and central Canada but involves perhaps only 50 to 60 square miles.

Birding is enticing because seasonal water dynamics create ever-changing habitats. During a four-year observation period, water levels ranged from dry or damp mudflats to deeply flooded potholes, pastures, and even roads. Moderate temperatures allow extended breeding and flexible stopover periods, so stop over, even if briefly, and enjoy! — Milton Weller

When to go

Year-round for waterfowl, shorebirds, and herons. Spring and fall are best for raptors and non-breeding shorebirds.


Restrooms at Baffin Bay Riviera Pier and Kaufert-Hubert County Park. Gas stations and several cafes in nearby Riviera.


Private farm and ranch lands accessed by public state and county roads. Roadside birding from vehicles creates the least disturbance.


Fields and potholes are usually fenced. Ask permission before walking in or around them. Traffic and disturbances are modest along smaller county roads; farmers and ranchers are understanding, and even the mailman waves!
