Hawk at Midsize Pond

After cleaning the midsized pond and refilling it, one of the first visitors to come by was the Hawk several days in a row. I'm not sure if he was actually hunting since the only residents of the pond were tiny tadpoles. There may have been a couple of small frogs but these little critters were a bit out of character for the large Hawk. He seems to go for large Goldfish and frogs.
