This State Wildlife Area follows the Rio Grande for several miles through willows teeming with Yellow Warblers. At the north end of the property, you will find the best riparian habitat, with mature cottonwoods and more willows; look here for House Wren, Cordilleran Flycatcher, Green-tailed Towhee, Warbling Vireo, Song Sparrow and the like. American Dippers nest under the bridge. In the open fields you may see coyotes hunting ground squirrels, especially early and late in the day.

Habitat: Mixed Conifer Forest, Stream, Streamside Willow, Lowland Riparian
