Bluetit in Montrose Basin Nature Reserve

Visited the Nature Reserve this afternoon  -  the Geese have started to arrive, but I couldn't get a good shot.  This dainty Bluetit was flitting about in the Hawthorn and I managed a nice shot of it.  There was also a Heron out a bit with his head his under his wing.  I waited for ages for him to show his face, but he wasn't obliging.  Then I whistled!  His head shot up in alert and I clicked the button - bingo!  -  see extra!
