We’re fortunate to be able to react to 2 instances here of Swifts’ nest sites threatened.
A visiting Swift lover noted that the roof opposite their annual holiday accommodation had had anti-bird combing installed since their last visit and Swifts couldn’t access. With ‘permissions’ 8 sections of black combing were trimmed, best looking access where tiles were raised or the gutter low. House Sparrows went straight in, a Swift was seen to enter the following morning.
We’ve also had a location where Swifts nest within a roof on top of the truss rafters, but Grey Squirrels have got into the loft causing mayhem. To owner seemed unwilling to trap the squirrels so we donated 4 nest boxes for the elevation where Swifts access, image below.
We’ve already had 3 new locations reporting their first nest boxes being used for the first time, all have more than 1 Swift box.
I think there are many more breeding Swifts still to arrive.
Best of luck all
