Glancing out of an office window, I did a double-take: a lump of snow in an old robin's nest had taken on the appearance of an icy bird in the light of late-day. Feathers hanging off the right-hand rim of the nest aid the visual trick. I shot the picture through the glass to preserve the angle of view necessary for the illusion. I expect "Frosty the Snowbird" to disappear entirely sometime tomorrow — we expect above-freezing temperatures.

Wonderful photo!! Nests are amazingly cool, I love the weaving on that one. Very special.
A lot of work goes into making a nest… love the illusion. Isn't it funny how excited we get about a day marginally above freezing?
Birds' nests are amazing. The robin who built the nest shown did such a nice job of weaving all those reeds, twigs, and other bits into a smooth basket. Funny how the "snowbird" mimics the appearance of the robin when she sat on her eggs last spring. — JG
I was so surprised at the appearance of that blob of snow and the feathers and was glad I had time to snap a photo. I have mixed feelings about our upcoming winter thaw: It'll be getting messy here when the snow begins to melt and if the ground is uncovered… well, the mess we see then will be unpleasant. — JG
So cool! (literally)
I've seen a few good bird nest field guides and have been tempted to buy them just for the photos.
