Adaptable Frogs

For the last 4 nights I have had a tree frog on the glass of my kitchen window. He/she comes when it gets dark  to hunt bugs as the light over the sink has been on  while I have been canning.  I wanted to get a better picture of the frog so I took the screen off the window , but realized it hadn't been washed since.........? Anyway as I was washing it the frog became shy and moved away from the middle of the window. I guess the frog  didn't like my attempt to clean the window...it disrupted it's feeding strategy.
