I think that's the attitude people have that keeps them on old media like twitter, reddit, and others. Blocking lemmy.ml did me some good, personally.
I'm not saying everyone should block lemmy.ml, just that the argument "but it's big" doesn't float.
Hmm... I probably missed it, but why are there so many colorful birds in the tropics? It just says that they probably came from outside the tropics, but not why there are so many.
Now that, is something I'd like to know too. My guess: to hide from predators.
Prey adapted to blending in to hide from predators. The majority of colors in the tropics are green (leaves), brown (earth, trees), yellow (sunlight?), and blue (sky).
For prey on the ground, the color of the ground, shrubs, etc. is probably green and brown. For prey higher up, if the predator is on the ground, probably blue, green, and brown are good colors to hide. Maybe predators of birds also have adapted to see other colors than the iridescent colors birds have.
Again, a guess, but maybe we'll know someday.
