I am not seeing so many swifts flying about in the evenings as usual. The screaming evening parties seem to have stopped for the time being. There is one swift on the nest all the time now and am hoping , if all goes well the first egg should hatch during the next week. I mentioned that this nest is in an old sparrows nest. A short clip where you can see a male house sparrow looking in at the nest. The swift inside takes no notice at all. In old buildings swifts and sparrows nest in the same areas. I believe that if there is conflict the swifts win out every time. Here is the clip.
