I was doing a moon flight a couple of seasons ago on the Tay, it was a very cold night, about -6. At about one in the morning i was walking off the marsh when i saw a pigeon fly along a hedgerow in front of me and land into a corner of a winter rape field. As i got closer my dog put six pigeon out of the same corner. I would be interested to see if anyone else has seen this before, it could have been down to the long cold spell, we came close to a cold weather ban that year. Could be a new line of sport, Pigeon by moonlight!!
