No loons to be seen over West Danby yesterday morning, because of the persistently falling snow. A brief but particularly heavy squall swept through between 8:00 and 8:30. Right in the thick of it, riding a tail wind out of the north, came a flight of Tundra Swans. I was indoors, but ran outside when I heard them coming. Invisible from the ground, but calling excitedly to keep together, they progressed directly southward until beyond my hearing.
