Mom was out doing her weekly garden clean up yesterday when thankfully she noticed this guy sunning himself by the fence. It is hard to see in the photos she took but he was two shades of grey with beautiful turquoise colored patterns down his sides. Thankfully he slithered off under the fence into our neighbors yard. After much researching online Mom finally found out it is a blue striped garter snake - non poisonous - they can grow to about 4 feet (this one was about 2 and half feet) and they eat earth worms, frogs, toads, small fish etc. They are commonly found in ditches, drainage areas and around ponds and of coarse we have a pond behind our house. Mom says he is quite welcome to feed on the frogs and toads in our pond as last spring/summer they drove us crazy with their noise although she would prefer he stayed OUTSIDE our fence :) When Mom looked at them online she noticed they vary hugely in the shades of grey and blue and even their patterns - one thing they all have in common is a blue underside - which this one also had. This is the second garter snake we have seen in our yard since we moved here and funnily enough - it was in exactly the same spot as the first one although the first one we saw was a brown and yellow garter snake.
