Little fluff ball Bluetit.....share all your pics of fuzzy fluffed up feathers here

So another cold day and mostly rain but little feather friends were out in abundance but it was a little bluetit that caught my eye sitting on top of a posted net (was previously used to prevent my son from kicking the ball through the trees and disturbing the wildlife thats in them, now its used by the birds to queue up for the feeders or grooming themselves as this is what this little guy was using it for today....

Yes I got carried away and it turned into a day of watching and comparing all the blue tits.

Is there a reason why this one is so fluffy?

Feel free to add your pics.
