I suppose those big bulgy eyes always seem to be watching, even if they are not really seeing. Twenty minutes later I approached again and barely got close before he leaped forty cm along the table and then leaped again, coming to rest on the seat below the table. That froggy spring had returned. I backed off to let him make a more leisurely retreat to safety. Just a few minutes later he was nowhere to be seen, probably back in his usual safe haven under the kitchen window.
Frogs are common around the house.
There are a few regular visitors to our kitchen window each night. They probably hide among the pavers stacked below the window, well out of the sun. We watched one over the summer and were convinced it was the same frog, getting bigger each week on a diet of small moths. The frogs on the window are quite amazing as they defy gravity. Their ability to crawl around on the vertical surface of the window is impressive enough but you can see their toes in action, sticking to the surface.
