Very interesting! Thanks for your explanations, Jazzerkins & TPC.
And now I know exactly what to do, if a songbird ever hits our living room window.
I actually did not know to put it in a box for an hour, to relieve it's stress.
I thought it was to be left alone, wherever it landed, till it recovered.
Thanks for the advice, TPC!
BTW, very fancy, schmancy hoods, indeed!
