Santa Ana Loop

More Information:

Santa Ana National Wildlife Refuge
LTC 059

This site is open for day use only.

Go west on US 281 from its intersection with FM 88 to the entrance to the Santa Ana NWR. Trails are open from sunrise to sunset. Beginning the day after Thanksgiving through April, a wildlife tram operates seven days a week. Summer tram tours are offered on a greatly reduced schedule. For a schedule and additional information contact the refuge.

At the Visitors Center, check the sightings kiosk and ask for a map of the trail system and information on guided tours and special events. Check the butterfly gardens planted in front of the center. In late September or October as many as 75 species of butterflies have been seen during a single visit to these gardens. Then check the water drip and feeders along the entrance to the all-weather trails. During the morning, the replenished feeders are magnets for White-tipped Dove, Plain Chachalaca, Olive Sparrow, and Green Jay. Look for Green Kingfisher from the bridge on the irrigation canal. Walk the trail to Willow Lake to look for waterfowl and Least Grebe, Red-shouldered Hawks perched in the trees in winter, and a variety of shorebirds in the shallows. Tropical Parulas very rarely nest or winter in the refuge where they weave their nests in the strands of Spanish moss. Watch for the long pendulous nests of the Altamira Oriole. Clay-colored Thrush are a common nesting species in the refuge. Unless the refuge is extremely dry, during winter and migration you should see all three kingfishers on this walk. This Spanish moss-lined trail often attracts tropical butterflies such as Julia, Zebra, and Mexican Bluewing. The large iridescent green dragonfly that seems to follow your every step is the Great Pondhawk.

Check the old headquarters site for Buff-bellied, Ruby-throated, Black-chinned, and (wintering) Rufous hummingbirds. The ancient Texas Ebony here attracts numbers of migrant landbirds; be sure to listen for the Northern Beardless-Tyrannulet's bee, bee, bee. The Tree Tower just south of this area offers a great vista over the thorn forest and a chance to scan for unusual Valley hawks including Hook-billed Kite and Gray Hawk. The Pintail Lake trail leads to the largest lake in the refuge, and (depending on season and water levels) is an excellent spot to find a variety of waterfowl, large wading birds and shorebirds.

You may also return to the Visitors Center via a trail that borders the eastern edge of Willow Lake. Look for Texas Indigo Snake, Texas Spiny Lizard, and Rose-bellied Lizard along this trail; check the cattails for Common Yellowthroat and Marsh Wren. Sora is often seen sneaking through the cattails, so take your time and walk quietly as you traverse this area. There are a number of trails that allow access to the Rio Grande including the Jaguarundi Trail where the only Crane Hawk found in the U.S. spent one winter. Other recent rarities have included Masked Duck, Blue Bunting, and Rufous-backed Robin.

During migration, stand on the levee that borders the north edge of the refuge and watch the skies for flights of raptors, or join the hawk watch in spring. Hundreds of thousands of hawks (including but not limited to Broad-winged Hawk, Swainson's Hawk, Mississippi Kite, and accipiters) pass over this area as they venture to and from the tropics. A massing of thousands of Broad-winged Hawks settling into Santa Ana NWR to roost for the evening is a sight no one should miss. The Alamo Inn offers birder-friendly accommodations in nearby downtown Alamo (956) 782-9912 (, and Casa Santa Ana offers overnight accommodations just east of Santa Ana NWR (956) 783-5540 (
