Black-necked Garter Snake
Thamnophis cyrtopsis
The Black-necked Garter Snake (Thamnophis cyrtopsis) occurs from parts of central Texas westward into New Mexico, Colorado, Utah and Arizona. It is often found along streams where it searches from frogs and tadpoles and sometimes minnows. The first image shown here was taken in Sabino Canyon, Pima Co., Arizona, in May, 2008, with a Canon EOS 1D Mark III and EF 300mm F/4 L IS lens and 2X extender. This snake was quickly swimming across a stream but stopped briefly allowing me a couple of head shots, then it took off again.
The Black-necked Garter Snake on the right was in Presidio Co., Texas, in August, 2013.
