Still flowering

I have carefully avoided mowing these yellow flowers all summer, but I'm not sure what they are.

I'm still cutting back shrubbery with a newly bought saw attachment for the strimmer (petrol driven variety). Not many birds about, but I did catch a glimpse of a harrier flitting round the forest which might explain it. Dragon flies were busy but didn't oblige.

I caught up with our difficult to obtain electrician today. Maybe he'll come tomorrow?
