Otro punto a favor de pensar en esta especie para mantener en cautividad, creo que es la gran variedad de hábitats en la que se la encuentra en la naturaleza (las distintas subespecies de A. contortix) -desde climas cálidos (como en Méjico y el sur de EE.UU.) hasta lugares con clima templado (que deben de asemejarse bastante a amplias zonas de nuestra geografía) correspondientes a una amplia franja de EE.UU., o incluso más fríos y secos.
A mí también me gusta bastante esta especies y subespecies.
"Within its range it occupies a variety of different habitats. In most of North America it favors deciduous forest and mixed woodlands. It is often associated with rock outcroppings and ledges, but is also found in low-lying swampy regions. In the states around the Gulf of Mexico, however, this species is also found in coniferous forest. In the Chihuahuan Desert of west Texas and northern Mexico, it occurs in riparian habitats, usually near permanent or semipermanent water and sometimes in dry arroyos (brooks).[3]
Found in the United States in the states of Texas, Oklahoma, Kansas, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Georgia, Florida, South Carolina, North Carolina, Tennessee, Kentucky, Virginia, West Virginia, Illinois, Indiana, Ohio, Iowa, Pennsylvania, Maryland, New Jersey, Delaware, New York, Connecticut and Massachusetts. In Mexico it occurs in Chihuahua and Coahuila. The type locality is "Carolina." Schmidt (1953) proposed that the type locality be restricted to "Charleston, South Carolina."
