When do garter snakes reproduce

The common garter snake has a dark, distinguishable head and a long slithery body. Its red and black, forked tongue is used as a detection device. This snake pops its tongue out of its mouth to collect chemicals in the air. The snake uses this process to detect scents like pheromones from other snakes and their next meal. The common garter snake hibernates from late October until about early April in natural borrows or holes and under rocks.

Once it emerges from hibernation, it begins the mating process. The common garter snake uses its tongue to seek out pheromones from potential mates. Once successfully mated, females give birth a few months later and each litter can vary from just a few to 80 snakes.

When they are born they are about Common garter snakes can be found in just about any environment except water. Marshes, fields and forests are just a few of the habitats these snakes can occupy.

During the winter months, common garter snakes hibernate in natural burrows, either in log piles or old rodent burrows, but sometimes come out to warm up their bodies by basking in the sun. Since the common garter snake can live in just about any environment, they are the most widespread snake in the North America.

In the North, individual females reproduce only every second year, or less often, because of the short summers. Litter size is usually small but the young are relatively large. The young are independent right from birth. Ball of red sided garter snakes. In summer, garter snakes are found in marshy areas where their main food sources, wood and chorus frogs, are abundant. Hibernation sites are often widely separated from summer habitats.

This forces the snakes to move long distances each spring and fall. Garter snakes are frequently killed while crossing highways and road mortality may be a serious problem, particularly in the Northwest Territories NWT where populations are small and productivity is low. Brood sizes in garter snakes vary from three to around 80, and geneticists have analyzed genotypes of six western garter snake mothers and their broods.

Three broods had a single father, two broods had two fathers and one brood had three fathers. For broods with multiple fathers, interpretation is complicated by the fact that garter snakes can store sperm. So a brood with two fathers may have been produced in a single mating ball, or a mixture of stored sperm and sperm received in a mating ball in the present year.

Although this mating ball contained only seven snakes, the constant squirming of entwined snakes was mesmerizing. Nevertheless, the visual impact of a truly large mating ball would be much greater.
