Mass migration

I know I now live in one of the major migration flyways. I know I'm not too far from where the whooping cranes come through on their way to Florida (I have got to see that, one of these years.) But knowing and getting distracted on the way to work by thousands of small birds rising in a cloud like candle smoke in a breeze, like sparks when a fresh log is thrown on the bonfire... wow. There's something quite comical about watching a thousand birds all try to land on the same stretch of telephone wire... I'm really surprised there weren't a lot of mid-air collisions and fallout of feathers. Nobody got into a tailspin, or crashed. Born flyers, that lot!
