Surprise find

We were a bit worried about the roots of a cotoneaster growing against the garage wall. They were starting to lift the slab path and could have been heading for the foundations! As there are other cotoneasters already growing there, we decided to chop this one down - and in doing so discovered this bird nest (fortunately empty at this time of year). I thought we'd had blackbirds nesting there but hadn't been sure as when spotted on his way back to the nest with grass or twigs, the blackbird would fly off in a different direction.
Now the leaves have fallen we've discovered more nests in the silver birch and rowan which we weren't aware of. Obviously the birds are clever at putting me off the scent!
