Thirsty horse

It was sunny and much warmer this afternoon, so we walked up past the farm.  The horses looked a lot more lively than they have been on wintry days, but they still all have their coats on.  This one was having a good drink when we got near, though it stopped to have a good look at us.  It kept flicking its tongue in and out of its mouth - I suppose that's what it must do when it's drinking.
