Yes, tree frogs I think.... and they were the easy ones to find... there are several others that I could hear but could not get to.... I am surprised some one has not complained yet but glad they have not .. I guess I could relocated some if they did . I love watching the cat get excited when they find a frog.. the smart ones play dead then the cats lose interest. Then there are the frogs that try to make a run for it to the pond. The cats get so excited about the frog some times they jump into the pond while chasing the frog without realizing what they are doing. Needless to say the cat is very unhappy when that happens.
