Hagerman National Wildlife Refuge Professional Review and Guide
"The 11,320-acre refuge was established to provide food and protected nesting habitat for waterfowl during the winter and migration seasons. The shallow marshes and ponds are usually full most of the year because of elevated lake levels. Only during very dry summers are the ponds and marshes partially empty. The Red River serves as the border between Texas and Oklahoma. Lake Texoma, an 89,000-acre impoundment, is managed by the U.S. Army Corps of Engineers. The 457-acre Eisenhower State Park is located in the southeastern corner. The dam site is near Denison.
Key birds: Wood Duck, Wild Turkey, Greater Roadrunner, and Redheaded Woodpecker are present year-round. Neotropic Cormorant, Least Bittern, Roseate Spoonbill, Mississippi Kite, Swainson’s Hawk, Chuck-will’s-widow, Scissor-tailed Flycatcher, Prothonotary and Kentucky Warblers, Indigo and Painted Buntings, and Dickcissel occur in summer. Ross’s Goose; Bald Eagle; Short-eared Owl; LeConte’s, Fox, and Harris’s Sparrows; McCown’s, Lapland, Smith’s, and Chestnut-collared Longspurs; and Purple Finch can usually be found in winter."
