i shot you an email ira. ok ray. i hope this hasn't shunned you away from getting some collared lizards. they are amazing animals and i just have a lot of respect for them. i just don't like to see them being taken out of the wild. they are in trouble as it is and people don't see that. but i'd love to hae another person in the hobbie working with them.

That's true! It's sad that they aren't bred more in captivity. It seems like common sense, not taking them from the wild (on an industry basis), less parasites, healthier animals. Ages known.

Are any of you guys breeding them in decent numbers or at all??

FWIW, their cage is 4 ft wide, 8 ft long, and 4.5 ft tall. I did faux rock work in the tank, placed some juniper branches in it, and have it illuminated by 2 shops lights (1 reptisun 10.0 and 1 5100K sun bulb [home depot] per fixture) and then basking area is heated with a 100w Active UV spot and a 100w GE Reveal bulb. Air temp at basking spot is around 92-96°F and cool end at 82°F. Surface temps are measured with a raytech IR temp gun, with basking at 128-135°F at hottest point of day and cool end reading 81-84°F. Habitat contains 1.1 twin-spot desert spiny lizards, 1.0 marbled whiptail, and had 1.1 collareds but my female dug under a "secure" rock and managed to crush herself. Rock has since been pulled from tank.

depending on who you talk to some say none of those even exsist and to others they should be a different species. but they look like beautiful baby eastern collared lizards. (Crotaphytus collaris)

Based on Western Reptiles and Amphibians by Robert C. Stebbins. 1985. 2nd Edition and Amphibians & Reptiles of New Mexico by William G. Degenhardt, Charles W. Painter, and Andrew H. Price. 1996. New Mexico has Crotaphytus collaris collaris, C. c. baileyi, C. c. fuscus, & C. c. auriceps. Where I live, southern NM, we would traditionally have C. c. fuscus or the Chihuahuan Collared Lizard. The Western Collared Lizard (C. c. baileyi) traditionally occurs not too far east or west of where I'm located (intergrade zones on either side), the Eastern Collared Lizard occupies the NE corner of New Mexico, and the Yellow-Headed Collared Lizard (C. c. auriceps) occurs in the NW corner of NM where it potentially intergrades with both C. c. baileyi and C. insularis bicinctores (which according to CNAH there is no more C. insularis and bicinctores is elevated to full species).

If I were fortunate enough to drive 6-8 hours west of my little home in southern NM I might be lucky to see C. c. nebrius (Sonoran Collared Lizard), but given I live in the Chihuahuan Desert I think the only thing sonoran I'll see are sonoran gopher snakes or sonoran mud turtles.

I'll go into work to snag my copy of the 2003 edition of Stebbin's guide to see what he accepted as taxonomic name changes to Crotaphytus and where he placed the subsequent ranges.

To further this even more, the Sonoran collared lizard was described as a subspecies, Crotaphytus collaris nebrius, in 1977 by Axtell & Montanucci and accepted in 2000 Crother as a full species, C. nebrius.

More taxonomic background on C. collaris http://www.tigr.org/reptiles/species.php?genus=Crotaphytus&species=collaris And if you want even more confusion you can look at The Center for North American Herpetology's take on the taxonomic structuring of the genus Crotaphytus within North America http://www.cnah.org/nameslist.asp?id=4
