Does a heron eat pond snail?

Yes, herons do eat pond snails. In fact, pond snails are a common food source for many species of herons, including the great blue heron, the green heron, and the black-crowned night heron. Herons typically hunt for snails in shallow water, using their long beaks to probe the mud or vegetation for their prey. Once a snail is found, the heron will use its sharp beak to break open the snail's shell and extract the meat inside. Pond snails are a good source of protein and calcium for herons, and they are also relatively easy to catch, making them a valuable food source for these birds.
