I had a visitor the other week, who stood with head cocked listening, then said, "I don't recognise that bird call." They didn't believe me when I said it was a frog until they tracked it down to the pond, then had to wait for it to settle down and 'tock' again.
It's not the 'ribett' or 'croak' that I usually associate with frogs. This makes a noise not unlike when you stick your finger in your mouth and pop it against your cheek (you know, if you're silly and do that - I won't say I had to do it to check and then to work out how to write it!). All I could think was a 'tock', like half a tick-tock of a clock. That deeper tock one.
Anyway, I don;t know if this is my noisy frog, but this little guy was in a bucket near the pond the other week, so I'm guessing it is the responsible one. Oh, good grief, I found him...well, what sort of frog it is anyway. I thought that was going to be way too hard.
Striped Marsh Frog. You can find info here and even hear the sound I'm hearing! The males do the calling, so I can keep calling him a him. Oh, I'm stoked now :) Some weeks i love doing this post!
