Oasis in the Desert: Bosque del Apache National Wildlife Refuge

The barren lands to either side of I-25 south of Albuquerque seem hardly fit for rattlesnakes, much less one of the Southwest's greatest concentrations of wildlife. The plants that do find purchase in the parched washes and small canyons along the road -- forbiddingly named hardies such as creosote bush, tarbush, and white thorn -- serve notice that you are indeed within the northernmost finger of the great Chihuahuan Desert, which covers southern New Mexico and southwestern Texas, and runs deep into Mexico.

However, to the east of the interstate is the green-margined Rio Grande. In the midst of such a blasted landscape, the river stands out as an inviting beacon to wildlife, and nowhere does it shine more brightly than at Bosque del Apache's 7,000 acres of carefully managed riparian habitat, which includes marshlands, meadows, agricultural fields, arrow-weed thickets on the riverbanks, and big old-growth cottonwoods lining what were once the oxbows of the river. The refuge supports a riot of wildlife, including all the characteristic mammals and reptiles of the Southwest (mule deer, jackrabbits, and coyotes are common) and about 377 species of birds.

A visit here during the peak winter season -- from November to March -- is one of the most consistently thrilling wildlife spectacles you can see anywhere in the lower 48 states, especially if you're an avid bird-watcher. Bosque del Apache is, you might say, the LAX of the Central Flyway, one of four paths that migratory birds follow every year between their summer breeding grounds in the tundral north and wintering grounds in the southern United States, Mexico, even as far away as South America -- and many of these birds either stop over here to recharge their batteries or settle down for the winter.

It's not enough to say that hundreds of species of birds are on hand. The wonder is in the sheer numbers of them. In early December the refuge may harbor as many as 45,000 snow geese, 57,000 ducks of many different species, and 18,000 sandhill cranes -- huge, ungainly birds that nonetheless have a special majesty in flight, pinkish in the sun at dawn or dusk. Plenty of raptors are also about -- numerous red-tailed hawks and northern harriers (sometimes called marsh hawks), Cooper's hawks and kestrels, and even bald and golden eagles -- as well as Bosque del Apache's many year-round avian residents: pheasants and quail, wild turkeys, and much mythologized roadrunners (El Paisano, in Mexican folklore). Everyone will be mesmerized by the huge societies of sandhills, ducks, and geese, going about their daily business of feeding, gabbling, quarreling, honking, and otherwise making an immense racket.

The refuge has a 12-mile auto tour loop, which you should drive very slowly; the south half of the loop travels past numerous water impoundments, where the majority of the ducks and geese hang out, and the north half has the meadows and farmland, where you'll see the roadrunners and other land birds, and where the cranes and geese feed from midmorning through the afternoon.

A few special experiences bear further explanation. Dawn is definitely the best time to be here -- songbirds are far more active in the first hours of the day, and the cranes and geese take flight en masse. This last is not to be missed. Dusk, when the birds return to the water, is also a good time. At either dawn or dusk, find your way to one of the observation decks and wait for what birders call the "fly out" (off the water to the fields) or "fly in" (from the fields to the water).

Don't despair if you can't be at the Bosque del Apache during the prime winter months, for it's a special place any time of year. By April, the geese and ducks have flown north, and the refuge drains the water impoundments to allow the marsh plants to regenerate; the resulting mud flats are an ideal feeding ground for the migrating shorebirds that arrive in April and May.

If you'd like to stretch your legs a bit, check out the Chupadera Peak Trail, which follows a 2.5-mile loop or a 10-mile loop to a high point overlooking the refuge. Ask for directions at the visitor center.

Just the Facts -- The Bosque del Apache National Wildlife Refuge is about a 1 1/2-hour drive from Albuquerque. Follow I-25 for 9 miles south of Socorro, and then take the San Antonio exit. At the main intersection of San Antonio, turn south onto NM 1. In 3 miles, you'll be on refuge lands, and another 4 miles will bring you to the excellent visitor center, which has a small museum with interpretive displays and a large shelf of field guides, natural histories, and other books of interest for visitors to New Mexico. The visitor center is open from 7:30am to 4pm weekdays, and from 8am to 4:30pm weekends. The refuge itself is open daily year-round from 1 hour before sunrise to 1 hour after sunset. Admission is $3 per vehicle. For more information, contact Bosque del Apache National Wildlife Refuge, P.O. Box 1246, Socorro, NM 87801 (tel. 575/835-1828; www.fws.gov/southwest/refuges/newmex/bosque).
