Apparently a lot of the ones in Reading don’t live in the town. They fly in from the southern Chilterns. The university had a project going where they were observing them with scopes from the roof of the Oracle shopping centre multi-storey (in fact I’ve seen it myself, towards dusk on an autumn evening… they were flying back from Tilehurst, over Waitrose and the railway line, towards the woods on the other side of the river).
I guess they fly in for pickings from gardens, takeaway shop bins, etc. Classy 🙂 But at least it explains how they might be sustaining near places like Wycombe. Dawdle around in the air doing big circles for a while, then when they get a bit peckish, off to McDonalds to nick discarded chips.
The thing that really interests me now is that there’s been such a steady growth for about a decade. Today really brought it home… they were everywhere.
