Last Swift fledged from one of our nestboxes on the house yesterday, 31st August (I think). No sign of any today. That makes 3 successful nests this year, up from 1 nest last year. I think the first fledgling from the first nest left on 21st July, so quite a prolonged fledging period - I didn't even realise the 3rd nestbox was occupied until a week or so into August. No cameras unfortunately, so hard to know what's going on inside the boxes.
