Also known as frost beard or ice wool, hair ice appears only on dead deciduous wood when the temperatures are hovering just below zero degrees and when the air is humid. It is a mass of fine icy filaments. These are incredibly slender, about .02 mm in diameter. Densely packed, they form a pearly cloud of ice. The slightest touch of a warm finger or even a breath will dissolve this fragile sculpture like cotton candy on the tongue.
Nice catch, Tony!
Very interesting info -- I've not heard of it before.
I'm learning new stuff today! This morning I saw a 'Leucistic' Downy Woodpecker on my backyard feeder -- never saw one before, and didn't know they existed until I researched it.
Of course, it scrammed before I could grab a shot of it.
