L. A. Dawson being more common in our area. In his excellent field guide: Venomous Snakes of Texas: A Field Guide (University of Texas Press), Andy Price stat- ed, “Hybridization between the two species does occur in the Big Bend, and the hybrid individuals may exhibit one or more characteristics that are intermediate between the two.” Andy was an academi- cian and employee of Texas Parks and Wildlife, a good biologist and a good person. We will miss him. In a past discussion I read years ago questioning why these two species did not hybridize more commonly (they are found in the same places all through their extensive range, from here to the Mojave desert in southern California and down into central Mexico), the authors conclud- ed they did not hybridize because in spite of seeming to be “sympatric” – occurring next to one another – they are actually “allopatric” – sepa- rated in time and space – and reproductively isolated from one another by a subtle differ- ence in the preferred “micro- fiche” between the two. Thus, while a general look at their distribution may have made them look sympatric, a much closer and more careful look showed they were allopatric based on fine-scale habitat preference such as soil type and plant type. This is not at all rare in nature. Small and seemingly inconsequen- tial differences in nature can have grave consequences in wild populations. While I cannot discount what the authors reported in their study concerning the reason hybridization between west- ern diamondback and Mojave rattlesnakes is so rare or even nonexistent in the populations they studied, I have found ongoing (i.e. across years) hybridization in the two rat- tlesnake species here in the Big Bend. There is a special location here in Presidio County where I like to go look for snakes. I enjoy the beauty of the area and the presence of the snake species sought by so many visitors who come to our area to find them. Whether you are hiking, cut- ting across a field or in your own garden, if you see a rat- tlesnake slide and glide across the path, step back and enjoy a special moment. It will, in all likelihood, go it’s own way. *For more information, google Karl Peterson’s article at: w w w. c h i c a g o h e r p. o r g / bulletin/46(3).pdf Monday - Saturday 7:30 am to 6 pm 701 O’Reilly Street • Presidio • 432-229-3256 St. James’ Episcopal Church, Ave. A and N. 6th St., Alpine Holy Eucharist 1st, 2nd, 3rd Sundays 11 a.m. Morning Prayer 4th and 5th Sundays 11 a.m. Godly Play for ages 3-9, every Sunday, Sept thru May, 10:00 am The Big Bend Episcopal Mission Welcomes You Santa Inez Church, Terlingua Ghostown Holy Eucharist first Saturday 5 p.m. Sept.~ May and 3rd Sunday at 6:30 p.m. The Chapel of St. Mary & St. Joseph, Lajitas Holy Eucharist on 3rd Sunday, 4 pm The Rev.
