Springwatch?

It’s not easy to figure out what’s going on here. This chimney is constantly visited by a pair of Jackdaws - earlier in the year with nesting material, but I’ve never seen any food going in. I suspect Jackdaws are regurgitators. We thought we saw a youngster appear earlier today, but then it quickly popped back in. 
It’s been a dull but dry day, so a chance to do a bit bird box and flower pot cleaning.
