The one hanging upside down is a juvenile, from the appearance of its spotted breast, which adults do not have.. At that age they can fly but are pretty clumsy. I’m guessing it managed to collide with the sheet or attempted to land on it and is now hanging on for dear life. Falling on its head just off the ground is unlikely to hurt it, but it won’t be pleasant regardless.
The one approaching it is an adult female, more than likely its mother, from the grey pattern on the back of her neck. That same area in males is solid white. She’s probably a little concerned.
Truth Coming Out of Her Well to Shame Mankind, 1896 by Jean-Léon Gérôme
I’ve been thinking a lot about it and this is literally the best title of anything
so I guess it was some ancient Greek who said “truth lives at the bottom of a well” and I don’t know what he meant or why it stuck, but I’ve seen a lot of 19th-century references to it (because people always love showing off how much they know about stuff)
but I like this because imagine how fucking pissed off you would be if you lived at the bottom of a well in the first place, but then you had to climb all the way out of it somehow because humans were such unbelievable assholes that you were forced to yell at them in person
