What a tit

Got quite a few decent pictures of... I think it's a blue tit? My book that helps me identify birds has gone walkabout, I'll have to find that at some point. Also discovered that the bird sanctuary at Duddingston Loch is a nesting site for herons, but even with a 300 mm lens and a 2x extension tube thingy I was barely getting anything recognisable.

Anyway, I think the fact that there was a tonne of brambles between me and the tit made it feel a bit more safe and secure in my presence, as it didn't take off in all the time I was there.
