This may be a birds' version of a milk moustache. Although there isn't any snow visible on the railing, there were several cm's of fresh stuff accumulating. Cool details if you have a moment to enlarge ...
After looking at all your bird pictures, I have put some bird seed out on my covered porch hoping to capture some up close shots from right inside the door. Your photos are beautiful.
Beautiful capture of his colour and details. I like his mustache. I was watching house finches today and one had its beak covered in snow...in fact it seemed to be eating the snow.
