Destination: Colorado : ENJOY THE FLIGHT : During their spring migration, beautiful sandhill cranes drop by the San Luis Valley for rest, a bite to eat--and some photo opportunities

ALAMOSA, Colo. — The air was filled with the calligraphy of birds, linear waves of cranes like Japanese writing against the sky. They seemed to flush out over the snowy San Juan Mountains, emerging in pulses that inched toward the area's barley fields and to the Alamosa-Monte Vista National Wildlife Refuge Complex where the sandhill cranes sink down each February and March to gorge themselves on abundant grain.

Like magnets, these southern Colorado feeding grounds--both in the refuge and in adjacent farms rich with grain left over from the fall harvest--are scheduled stops for the estimated 20,000 birds during their annual spring migration from winters in New Mexico to spring breeding grounds at Grays Lake National Wildlife Refuge in Idaho.

This San Luis Valley wildlife refuge--actually two separate areas that total more than 25,000 acres, divided into plots on either side of Alamosa, Colo.--is part of a federally funded chain of more than 500 around the country. As part of the U.S. Fish and Wildlife service, they provide food, water and shelter to a wide variety of wildlife in an effort to help preserve various species and encourage breeding. Visiting this Colorado complex is an excellent way to witness these birds in their natural habitat.

Another way to mark their spring arrival (the birds are generally gone from the area by the first week in April) is to visit the town of Monte Vista for its annual Festival of the Cranes. This year it will take place March 23-26.

The festival is a charming small-town celebration featuring pancake breakfasts, barbecue dinners, wildlife workshops in bird identification, a photography seminar by nature photographers, bus tours of the refuges and surrounding areas, nature lectures and trips to the stunning Great Sand Dunes National Monument nearby. Prices for various events range from free to $30. Last year was the fourth time I had returned to the area to see the sandhill cranes. They are so dynamic, graceful and haunting that they linger in my consciousness, and seeing them again and again has become kind of a ritual--my way of welcoming the cycle of spring.

Also part of my rite of spring has become a visit to the Great Sand Dunes National Monument, about an hour's drive northeast of the town of Monte Vista. While it is not bird-filled, it has striking beauty and fits perfectly into a nature lover's pilgrimage to the area.

But a year ago it was the wetlands where I headed first, because I knew the birds would be there. Scattered throughout the San Luis Valley, the wetlands are an additional draw for the cranes, as well as for numerous types of waterfowl that like the security of the habitat, including snowy egrets, black-crowned night herons, avocets and up to 30,000 ducks during the height of their March migration.

The wetlands were formed by natural and artificial dikes, irrigation ditches and ponds, and from underground aquifers filled with melting snows from the San Juan and Sangre de Cristo mountains that surround the valley. They combine to provide farming irrigation--necessary because the valley is actually a high, arid plateau that receives only about seven inches of precipitation each year.

I was among the lucky few who last year spotted two rare white whooping cranes (who take their name from the sound of their call) within a group of comparatively grayer sandhill cranes. The whooping cranes show up because of a breeding program that was started in 1975 in order to increase their population. (In 1941, only 21 whooping cranes, a species unique to North America, remained in the wild. Now, with their numbers expanded by breeding programs, there are an estimated 150 in the United States.) Scientists were allowed to take one of every two eggs from breeding-ground nests in Canada--where whooping cranes are also nearly extinct--and to move those eggs to the Idaho nests of sandhill cranes.

Since whooping cranes learn migration patterns from their parents, there are only a handful that fly with the sandhill flock to rest and feed at the Alamosa-Monte Vista refuges, which are among the main stops along the path they take from Bosque del Apache National Wildlife Refuge in New Mexico to Idaho--a journey of more than 800 miles.

Some of the best points from which to view the four-foot-tall sandhill cranes and other birds are found along the Auto Tour Route, a trail that wends through the Monte Vista refuge. It starts from a small parking lot at the Visitor Contact Station on the refuge and meanders through the wetlands and near fields of barley and rows of craggy cottonwood trees. I drove the route and was rewarded with rich views of breeding and migrating shorebirds, including the humble little brown-and-white killdeer.
