My favourite month has to be November, It's usually the time that the centre goes a little quieter. All the Hedgehogs are thinking seriously about hibernation. Baby bird season is well and truly over (except the pigeons who seem to produce all year round!) The only pitfall is we seem to get more juvenile cygnets in..they haven't quite learn't the art of flying and seem to crash land on wet roads(thinking they are rivers!).
So yes for me it's November, then again December and January are quiet too
