Could be ice (that would definately explain the thin beard). Could also be from rocks and or hills (if that applies to your part of the world). Other possibility is just from mixing it up with other birds. A bird with 1 1/4" spurs is (generally) an advanced three, typical four year old. Its all generalization.

You wouldn't happen to have the spurs and a camera handy would you? Always easier to see than be told you know...
