http://digital-desert.com/wildlife/red-racer.html Incorrect Latin name^^^ The snake listed on the page above is actually a red color phase of the western coachwhip. Sometimes called "red racer". However, it is a coachwhip, (Masticophis flagellum) not truly a racer. You have listed the Latin name incorrectly as "coluber constrictor" which is a different, unrelated snake and is a true racer.
Apparently I had a picture of a coachwhip snake on the red racer page. This has been corrected by replacing the photo.
I remember some confusion when I put the page up initially. Hopefully this clears that up, plus it makes a nicer-looking page with the larger photo.
