The nest itself is rather interesting, and I thought you’d like to see this:
Apart from feathers a lot of it seems to be made up of grass or reeds. We’ve not seen this before. No sparrows have entered the box either, as the swifts are there quite a lot of the time. So there must be quite a bit of grass floating about in the air!
So sadly this year we are down to just one pair of swifts, from what were three pairs a couple of years ago. We just hope that with the second and third waves we might get some prospectors for next year.. Here they are in their grassy nest!
