Greater biodiversity

I like how in recent versions nature became more diverse in Minecraft, so I suggest adding a few more animals: — Reindeers in tundra, peaceful mods that drop leather and 1-2 antlers when killed. — Seals in polar seas, peaceful mods that crawl slowly, but swim quicker, drop leather and blubber (the latter can be used as fuel for furnace). — Eagles in mountains, neutral mobs that attack if you come too close or hurt them, but can also be tamed with raw chicken. — Seagulls in the seas, basically have the same function as bats in caves. — New bear species depending on the biome, such as brown bear in temperate forests and sun bear in jungles. — Strix in forests, hostile mobs looking like large black owls that attack at night, but sleep during the day. — Forest cats in temperate forests and fishing cats in swamps, basically the same as ocelots in jungles.
