I would recommend The Bird Watching mod, Sophisticated Wolves, Axolotls Version 4, Camels Mod, PrimalMobs, More Mobs, and Multimobs. Also TekTopia if you want better humans.
I also see you have Koopa's Critters, which is a really good mod. It is the only mod that adds a spoonbill, my favorite animal. I would reccomend using the spoonbill for Swamp/Beaches or walk-in aviaries.
