Just looking at the rafters of the roof outside and I see there is a nest built there for those flea ridden shite producing birds called the Swallow. So what I want to know is "Where did they nest before mankind started throwing up houses for them to defecate all over?" I mean the were / are only so many cliff faces out there. Surely these ungrateful feathered vermin must have had a population surge over the last few hundred years. Yet the RSPB says they have taken a hammering. How the hell do the RSPB know what the population was back in 1200? And donât get me started on the bloody Magpies.
