More bird data

So just now - 8 pm - full sun gone from the terrace. It's still daylight but shaded out there. One of those gray birds just flew into the glass door. He then flew away and two of his brethren perched on the railing for a long while.

Bird intel must be that Biggie has gone to bed early, as he is wont to do, under the bed in the bedroom.

But, flying into the glass door is not your Mensa move.

The glass reflects to the birds' eyes whatever you're seeing (or can see) when you look out the window/glass door, so to them it appears to be navigable space and they fly right into it. I used to read that if you had curtains or draperies at the window---closed curtains or draperies, I mean---it would appear to the birds that the glass was a solid object and they'd avoid it, but my mother never opened the sheers covering the living room window (and never closed the actual draperies, dunno why) and birds regularly stunned themselves by flying smack into the glass.

That was out in the boonies, where what was reflected to the birds was a lot of very open space, seemingly distant oaks and maples and beeches. Plenty of flyin' room!
One time, Mother went out on the front porch to remove what seemed to her to be a dead bird. Just as she was about to pick it up (with a rag, some newspaper, something) the bird came to and flew away. That was her last attempt to rescue or remove.
