Not a tall story - just a long tail

I struggle to get to Farmoor very often these days, but a visit on other matters gave me an opportunity to take in the very striking Long Tailed Duck that was traveling back and forth the length of the causeway on Farmoor 1. It was diving and reappearing every thirty to fifty yards and often staying under for quite a long time.
