If it don't go elsewhere, it goes here.
Some of them are transient, they just know there's food to be had and no one bothering them. That's true of the ducks and geese, who are native to that region. The eagle stays because it cannot fly. A lot of wild birds get injured, and then are crippled until they starve. Wild bird rescues try to save them. But birds have very fragile bones, and their bones often don't mend well, even if they are treated properly. So some of these bird sanctuaries are for these birds who have been saved, but cannot be rehabilitated to the point where they can fly again. Or at least can't fly well, or without a lot of pain. Mercedes Lackey wrote some things about being a wildlife and wild bird rehabilitator. Which is where I first learned of it. Birds play a large part in her writing.

We do need fewer threads about birds.
Best bird encounter I had recently was a close-up encounter (like, it was a handspan away from me) with one of these:
The goldcrest is I believe the smallest bird in Europe. It is about the size of a chicken nugget. I managed to avoid hunting the one I saw but I definitely could have got it, it was acting pretty stupidly for such a small bird.
Incidentally we also have this bird, the firecrest, which is much more punk rock. I've never seen one of these though, I'm probably too mainstream for it.
Try to be the reason some guy receives a free fidget spinner.
