Biomes need more animals

I think Minecraft needs more animals that simply make the world feel more alive. Right now, many biomes feel empty because there aren't enough mobs living in them, which makes exploration less exciting. Atmosphere is an important part of gameplay too, and not every feature has to be measured by the items or resources it gives the player. Many people enjoy building zoos, nature reserves, villages, and other creative builds, so having more wildlife would make the Overworld feel much more immersive. Not every animal needs a unique mechanic or useful drop on release, if there's no gameplay purpose yet, new interactions can always be added in future updates. I would love to see more birds, mammals, reptiles, and other wildlife that fit naturally into different biomes and make exploring Minecraft more enjoyable.
