Birds, owls, ostriches and vultures - Part 2

2.Owls: owls are special. They can apparently live in warm and cold region in the world, so what we could do, is to make them spawn mostly in cold forests and rarely in temperate forests. Just like birds, they would have some different textures, but just enough to make them collectable like wolves and cats (So biome variant owls). They would drop feathers when they die, the same percentage as chickens, maybe higher. They would be tamable with raw and cooked chicken and raw and cooked rabbit, but would still be able to eat raw and cooked salmon, raw and cooked cod, tropical fish and rabbit's foot (rabbit's foot will do something special).

When tamed, owls are basically flying wolves, right click on them to make them sit down, being able to attack mobs on demand and attack who is attacking the player. They would however not be able to wear armor, because flying mob, pretty straightforward. Something cool they could do is, when fed a a rabbit's foot, they will start flying in the sky and scanning the zone in a radius. This would make the closest 16 hostile mobs glow, counting endermans.
