Dear Anthony, The two species of whip-poor-wills are quite distinctive visually if the bird in question was seen in good light. Eastern Whips are predominantly and obviously gray, again in good observing conditions, while Mexican Whips are brown. They are not rufescent like a Chuck-will's-widow. If the bird happened to be a male, the tail pattern of these two taxa are also very different with Eastern Whips showing more than twice as much white as a Mexican Whip. With females, differentiation in poor light of a flying bird would be problematic in my opinion. My feeling is that the Whips in the Lubbock area are going to be Easterns, but we have a lot to learn about the dispersal potential of Mexican Whips. Mark Mark Lockwood 402 E.
