Zone-tailed Hawk

Your range map of the Zone-tailed Hawk needs to be a bit farther east for its range on the Edwards Plateau region of Texas. Further, it also is found in Jeff Davis County, Texas in the Davis Mts. Also, it is regularly found in the Big Bend, including Big Bend Ranch State Park (2 successful nests in l997), along the river in BBNP and in the Chisos Mts., and up river to the east along Black Gap Wildlife Mgmt Area.
