There is a lot to envy about birds, but I'm not sure I would want to be one during a cold winter.
Lovely, lovely shot!
Not so sure about the interpretation however - to me that flash of beautiful light and colour represented by the bird in an otherwise almost monotone (but very beautiful) winter scene is a thing of wonder, of life triumphant!
Think about it - this bird and its ancestors have been perennial inhabitants of this environment for millennia. All the migratory species buggered off months ago for warmer climes. To this bird though - this is home!
(Not suggesting for a second though that there might not be casualties through a winter, never mind a particularly cold one.)
Beautiful shot - and real food for thought!
