This small rest stop along Canyon Grande Creek provides good riparian habitat for Green, Belted and Ringed Kingfishers, and southerly specialties such as Couch's Kingbird, Vermilion Flycatcher and Black Phoebe. Farther south, in the community of Normandy, there is a small population of wintering Sandhill Crane as well as an occasional Burrowing Owl. Roads throughout the farming valley provide excellent diversity for a variety of South Texas species.
