This bullfrog came to check me out at the edge of his pond in the Don Valley, and did so from many different angles to be sure I wasn't causing trouble.
Yes, I am a broken record but - like so much stuff - frogs and toads are plentiful anywhere in Toronto. Just check around any pond or marsh-like area and if you can't see them just listen: if there's a weird noise that's not a bird and seems to come from nowhere in particular, you can be almost sure it's some type of frog. You can also spot them by looking for a sunny area in a pond. They like to catch their rays in the morning.
