It's that cormorant again

The juvenile cormorant that I spotted early in December seems to have taken up residence on the stretch of the River Aire between Hirst Weir and the aqueduct. One day when I passed, it was perched on a tree stump grounded on the weir. Perhaps fish are easier to catch as they tumble over the weir? From a distance I thought it was the heron, which often frequents this spot, but as I got closer I could see it wasn't. Handsome birds, aren't they?
