We (me and the neighbours) see a variety of birds with a treecreeper being the latest spot however the site is dominated by wood pigeons which not only eat all the bird seed they also crap everywhere which is a real nuisance when you're weeding under the trees and they decide to poop over you.
I've put up a lot of bird houses and despite a blue tit inspecting one of them there doesn't seem to be any long term habitation. Fingers crossed for next year.
When we lived at Rothersthorpe the only time we saw a heron was when it was emptying the pond of frogs. I hope your heron wasn't visiting a pond near you. Time to go out and fill the bird feeders...
