Help!

This poor little greenfinch fledgling had somehow managed to fly onto our roof but didn't know how to take off and fly away. For at least 10 minutes it struggled a metre or so up the roof each time and then would slide down again. It was absolutely exhausted but eventually when it reached the ridging it managed to fly over. There was no sign of it at the front so I hope it was safe then.

I had to zoom in and crop the picture so it's not very clear.
