Up on the roof

That's a good song title from the past? Well my past,at least.
    The Wagtail today was spending a lot of time on the house roof.
The roof on the back of the house has a lot of moss.And I noticed it had been pecking around in it.
   I wonder if there are still insect amongst it?


As you can see I have added a Watermark to my pictures.Some liked them so much that they wanted them for themselves?? Sad really!
