Mating ball of garter snakes caught on campus

Males employ an anoxic kiss to reduce feminine struggle while increasing compliance

The dam that types Varsity Lake from the University of Colorado campus is solid, however riddled with crevices offering safe havens for western garter that is terrestrial, Thamnophis elegans. Desperate to witness the many fulminations of spring, we examined the walls on hot times in April to look at very first plants for the snakes basking under the sun. On April 15, five snakes had been basking near the top of the wall surface, but more snakes were below the dam, in the forests. We resolved to go back the day that is next a digital digital camera.

The morning that is next a set had been mating next to the wall towards the top of the dam, however they had been partially concealed by dandelion foliage and plants. But, the genuine action had been taking place underneath the dam into the forests, where a roiling, seething, slithering mass of snakes had created a mating ball.
