I have had to work hard with the flycatchers nesting in my garden wall. They have lost broods in previous years to predators, notably jays. I installed wire netting to prevent this happening this year. Imagine my surprise when our local kestrel turned up! This is the moment he realized that he was not going to get the chicks and gave up (the nest is in the moss behind his right claw). I am delighted to report that the young all fledged successfully at the weekend.
