Worked in Paisley today, so kept an ear open for the urban Raven, but no luck. Strikes me that this must be a non-breeding bird as breeders will have fledged young by now. However there were occasional reports over the winter of two together, so I suppose there is a slight possibility that he may be one of a pair with a nest somewhere (although surely someone would have reported stick-carrying etc). Urban breeding wouldn't be that unusual - I remember when pairs started to nest on Chester Cathedral and Cardiff Guild Hall in the 1980s. They were unusual then, but probably not anymore. There is a pair almost certainly breeding in central Edinburgh and a pair nested on the floodlights at Blackburn Rovers in 2009. Other urban sightings have come from Maryhill in Glasgow, the centre of Ayr and the pair I saw over Greenock a few months back.
