How many can you see?

Opening the blind in my bedroom this morning, I saw lots of ripples on the surface of the pond at then end of the garden. On closer inspection, still from the window, I could see frogs jumping into the pond left, right and centre!
I grabbed the camera and went outside. Silence. Nothing. All signs of life had disappeared. So back upstairs I went, opened the window and, sure enough, they appeared again. Even from a distance of about 20m, they seemed to be watching me. I didn't have a chance to get any closer, so this is what I got. Still, there are quite a few eyes to be seen in this shot, so I'm quite pleased really.
The extras show the great mounds of frogspawn they have deposited!
