KREMMLING In the gray light of dawn, hundreds of swallows darted over a pool of standing water in an irrigated field along the Colorado River. The birds were attracted to the early-morning mosquitoes swarming the saturated landscape. Bill Vetter, a wildlife biologist with Wyoming-based Precision Wildlife Resources, methodically counted the birds. For six minutes, he marked down every bird he saw or heard at eight locations across the ranch, 250 meters apart.
