As very late back last night a very busy day mainly in garden and puppy minding. I had a bit more time to check the cameras. This morning 6 swifts screaming low around the house. They acted like bangers. One or two year olds investigating possible nest sites for upcoming years. I am now sure that there are 3 chicks in the chimney nest but one is much smaller than the other two. It may be okay if there is plenty of food but the weather forecast isn’t too promising. A clip of each nest.
