A visitor in the wood burning heater

I happened to glance in through the glass-fronted door of our fireplace this morning and was rather surprised to see staring back at me an agitated fairy martin which must have somehow flown down the chimney and landed in the fireplace. I don't usually make a habit of looking into the fireplace very often so this is one lucky, unlucky bird. It was quickly caught, duly photographed and liberated outside.
