no we dont rob although i suspect theres a reasonable number of escaped birds knocking about
the snakes are grass snakes (harmless constrictor grows up to 1.75m long)
we also have a poisonous one called the adder /common viper up to about 2ft long the bite can be serious if not treated in good time but is rarely fatal
the smooth snake similar in appearance to the grass snake and without seeing the head it could easily be either of the ones in the pictures as it particularly popular around where redtail lives
and there is also the slow worm which is often refferd to as a snake but is actually a legless lizard
