Craff, cuddy, grey spadger, roo-doo, sparr and sprug, spuggie and spurdie…. These are all regional names for the sparrow, both the House sparrow (Passer domesticus) and the Tree sparrow (Passer montanus). My ex, a Lanarkshire Scotsman, called it a speug, so that name is one I still sometimes use. And I’m sure many of you will have your own names for this little bird, one of our most common urban garden companions.
