A Creeping Menace

Several weeks ago I saw a Crow with a Doughnut in Bristol. The object was clenched between its beak as it flew in and landed on a roundabout before proceeding to attack it. I should clraify that this wasn’t a ring doughnut either, it was great (if somewhat unaerodynamic) work from the crow. Today, walking to the station I saw a crow fly down, land on the road and snaffle a pitta bread that was lying there before flying off, it’s prize clenched between its beak. What do crows want with our baked goods? It is part of A Plan? Concerned citizens want to know.
