Spotting

Looks like the pacific tree frog. This species I have here at the house . The croak of the pacific tree frog is said to be used in movies and tv for they are so loud . Some folks feel they can be rather a "pest", once they establish themselves somewhere, however I LOVE them and they are allowed everywhere at my house/property.
They do change colors , they tend to change to their surroundings and feed on insects of course. I feel they are carnivorous for I watched a bigger one stalk a smaller one, however this is just my own observation.
Hope this helped!?

Nice frog.
