This is an easy stroll on a combination of paved path and dirt road through a variety of habitats supporting up to 20 species, including local birds and, especially in spring and summer, a number of seasonal visitors. From Mammoth Creek Park West, follow the Town Loop east through the tunnel and continue downstream along Mammoth Creek. In the pines, look for Steller's jays, mountain chickadees, nuthatches, and dark-eyed juncos. In the snags near the bridge that crosses to the Hayden Cabin, look for Cassin's finches, pine siskins, and northern flickers. Scan for nesting holes used by tree swallows and mountain bluebirds. Check the willows along the creek for migratory warblers. When you come to the dirt road, leave the path and follow the road, staying along the creek. The open Great Basin sagebrush country on your left is excellent habitat for Brewer's sparrows and green-tailed towhees. When the road comes again to the Town Loop Path, loop back toward the Hayden Cabin. Cross the bridge and explore the open meadows around the old structures, watching for flycatchers and maybe a western wood peewee. On your way back to Mammoth Creek Park West scan the sky to the south, toward the Sherwin Range, for red-tailed hawks riding the thermals.
