Sandhill crane (Grus canadensis)
During the summer sandhill cranes are far to the north of us, in Wyoming, Montana, Alaska, Canada and even as far as northeastern Siberia. There they build nests in shallow water and raise their young. The nest is usually a mound of wet vegetation in a marshy area. The parents take turns incubating the (1 or 2) egg(s) over a period of about a month.
A pair will generally raise one or two chicks each year. The chicks are downy and able to move about on their own within a couple of hours after they hatch.
The chicks are carefully raised by their parents for up to four months. The young cranes spend their first winter and spring with their parents, both in migration and at their wintering grounds. The sandhill cranes begin to arrive in Arizona, Texas, New Mexico and northern Mexico in October and remain until February, when they return to the northern nesting areas. While in these wintering areas, they prefer shallow water roosting sites near harvested grain fields. That makes the Sulphur Springs Valley ideal for them. They spend the nights in the wetland areas and go forth each morning to the harvested grain fields of the valley to feed. Corn is a favorite but they also eat sorghum, wheat, alfalfa and grasses. Sandhill cranes are gray in color with black feet, legs and bill. The Arizona Game and Fish Department estimates the average number of cranes in the local Sulphur Springs Valley to be between 8,000 to 12,000 birds each winter. However, the 1996 sandhill count showed the highest total ever with over 24,000 birds. This might have been due to drier than average conditions in other favored roosting areas in New Mexico and Mexico. Taking a larger area, which included the Willcox Playa, Crane Lake, Whitewater Draw, Safford Valley/Duncan and Bonita, biologists came up with a toal of 30,570 birds in 2005-2006. This number comes close to the record number of 31.442 spotted in 2004.
Birds can be seen in the evening in the wetland areas around Willcox, the Whitewater Draw area and the AEPCO (Arizona Electric Power Cooperative) viewing station (see directions below).
If you wish to see the birds in the feeding areas, highway 191 from the town of Cochise to Dragoon Road and Kansas Settlement Road from highway 186 to Baker Road are good spots to try. Early morning is the best time.
AEPCO Crane Viewing Station Each January the town of Willcox pays homage to these impressive winter visitors at the "Wings over Willcox" birding festival. January 13-17, 2010 The cranes usually arrive in October, and they generally remain in the area until at least the end of February and sometimes into March.
