Animal Spawns
Where the animals live, and which vanilla animals make room for them.
Most animal spawns are controlled by biome tags such as wildernature:spawns_deer, so datapacks can add or remove biomes.
By default, pigs and chickens no longer spawn in forests, farm animals are removed from savannas, swamps and jungles, and frogs are added to jungles. All of this can be turned off in the config.
