Bitter Lake National Wildlife Refuge

Bitter Lake exists because of water rising from underground. Springs fed by a deep aquifer bubble up along the Pecos River, some of it fresh and some of it heavy with dissolved gypsum and salt, creating a mosaic of lakes, marshes, playas, and salt flats. This mix of fresh and salty water in a dry land makes the refuge a rare and precious habitat.

The gypsum-rich water has also carved sinkholes into the ground, deep, clear pools that add to the strange character of the place. The result is a landscape found almost nowhere else, a lush, bird-filled wetland surrounded on all sides by desert, an oasis that has drawn wildlife and people for thousands of years.

Bitter Lake sits squarely on the Central Flyway, the great migratory highway that carries birds between their northern breeding grounds and southern wintering areas. Each fall the refuge fills with waterfowl, and by winter its waters hold tens of thousands of sandhill cranes and snow geese, along with countless ducks, that lift off in clouds at sunrise and pour back in at dusk.

The show changes with the seasons. Spring and fall bring shorebirds and songbirds passing through, summer holds nesting birds and herons, and winter is the grand spectacle of cranes and geese. More than three hundred and fifty bird species have been recorded here over the years, making the refuge one of the premier birding destinations in the Southwest.

Come the warm months, the refuge becomes a paradise for a smaller kind of flying wildlife. Its wetlands support one of the richest concentrations of dragonflies and damselflies in North America, with a great many species darting over the water, and it draws enthusiasts who come specifically to see them. It is a reminder that a healthy wetland teems with far more than birds.

Beyond the birds and dragonflies, the refuge is home to mule deer, coyotes, jackrabbits, and a variety of reptiles and amphibians, along with rare fish and snails found in the spring-fed waters. The salt flats and sinkholes even shelter species adapted to the mineral-heavy water, small survivors that make the refuge important to scientists as well as birdwatchers.

The best way to experience Bitter Lake is the wildlife auto tour loop, a drive that winds past the lakes and marshes with pullouts for viewing, letting you watch birds from the quiet of your car. Short walking trails and overlooks add closer views, and a visitor contact station offers maps and current wildlife news. Binoculars or a spotting scope make an enormous difference.

Winter is the marquee season, cool and clear, with the cranes and geese at their peak. Spring and fall are pleasant and full of migrants, while summer is hot and best enjoyed in the cool of early morning, when both the birds and the dragonflies are most active. Whatever the season, dawn and dusk are the magic hours at the refuge.
