The Little Thrush Did Recover

 If I had been outside away from the house when this little thrush (Hermit I think - re they are the most likely winter candidate in this area and the colorations fit) flew into the window pane I am fairly certain he would have died in the cold icy snow for he was in disarray and not moving when I picked him up.  No chest movement at all and completely limp.  I cupped him in my hands and went inside before the wood stove and after about 10 minutes or so his chest started to move even though his eyes were still dull and distant. Gradually he became more living though not making any efforts to wiggle or escape being cupped within my hands.  I loosely wrapped him in an old worn bit of cloth table napkin and took him outside and after a small amount of time maybe 10 minutes or so he wanted free.  The above picture is where I put him on the porch chair just before the one I already posted with my hand across its shoulder - when I had moved my hand off, it flew off like new.
