Argentavis

So I've read about an ancient giant extinct bird called Argentavis. It size was about as big as an adult man and its wing span can reach about 10 meters, and I think it would be great if we can bring this magnificent aves back from the death to the land of Minecraft.

Argentavis will spawn high on mountain biome or extreme mountain biome. It will have dark purplish coat and bone colored face and feet. Just like other predatorial birds, Argentavis will occasionally swoop down to the land and hunt goats (feature of cave and cliff update). It will also hunt phantoms and zombies at night so it can be a great air defense.

There will be two mechanics of Argentavis attack:

1. It will carry its prey from the ground and drop it from various height

2. It will snap its prey with its beak (mobs that immune to fall damage will always get this attack)

If we kill an Argentavis, it will drop feathers and bones (or any other else, I am not quite sure for the drops). This creature may behave neutral, but it can trust players by feeding them meat or fish which will be 1/25 attempt. Argentavis will not hurt player who they trusted even if it got hit. Also, I think flying mobs in Minecraft are less in number rather to land or aquatic mobs, so I think this would be a cool idea.
