Frozen Feather

Wondering what to blip today so raided the blipbox and retrieved this feather which was picked up on a beach during the summer. Someone out there will doubtless know what species of bird it came from. I don't know, but my guess is that it is most likely to be a Curlew.
Anyway. into a Tupperware box full of water it went and into the freezer. When nicely frozen, took it out into the sunshine and "blip". Here you have it..."Frozen Feather".
