Very close friends!

I certainly didn't expect to see any frogs in an ornamental, straight sided pond where there is no vegetation ..... but in the pond in Greenbank Gardens there were quite a few frogs and peering closely into the murky water I could see some collections of frog spawn.

Judging by this female's swollen abdomen I suspect that there are many more eggs to come.

Some marginal water plants would have made the photo just a bit more interesting.
