There are thousands of sandhill cranes who winter at the Bosque del Apache Wildlife Refuge in southern New Mexico. They spend their nights sleeping on the big ponds of the flooded fields and during the day, they feed in the fields that have been cultivated to provide food. They're relatively shy birds and keep their distance from all the park visitors, but their daily routines are fairly predictable. So photographers can stake out along the edges of the ponds and the fields during the "golden hour" of light in the morning and evenings and capture them in all their grace and beauty as they travel past.
