We all know that the animals found in minecraft are not amazing from a behaviour and graphic point of view, but also the fact there is barely any different types of non hostile mobs, we have cows pigs sheep and chickens sure but there not exactly mind blowing, I believe that the developers of mine craft are doing other projects such as new biomes and new bosses as well as dealing with bugs so I doubt they have time to add something like mobs but I believe the many enthusiastic modders do, and because of that belief I am sharing this idea with you. Because we already have a few land based mobs and because 1.8 added a few sea mobs as well as structures I believe there is only one place left that requires mobs, the sky. Let's face it guys we have one kind of bird in mc that doesn't even fly all it does is fall slowly. I believe that we should have a mod that give us multiple diffrent kinds of birds spanning over every biome. Each biome should have a bird that is similar to the birds that live in those areas in real life. For E.G vultures and ostriches living in desert biomes and fish Eagles living over rivers lakes and oceans. We could also have neat touches like when macaws die you obtain clay because macaws eat natural clay as a anti toxin.
Thanks for reading and please post your views below.
p.s sorry for bad grammar havent skept for a week
edit: also all birds like ostriches could be able to kick a player if agitated. They will have a high melee attack because an ostriches kick is pretty brutal.
