Hawks are medium sized birds, mostly found in areas where there are a lot of trees. The perfect biome for this bird in mine craft would be a roofed forest biome, where players can have them partnered with wolves and survive many days within mine craft. The hawk will come in three different textures and types which are:
1. The Ornate hawk-eagle (Black body with a orange head and black feathers on top of it's head. Also has a black and white belly.)
2. The Broad-Winged hawk (Dark yellow all around but has a white and brown belly)
3. The Harris hawk (Brown and white body with a faded yellow under the feathers)
Spawning: These bird will be found in roofed forest biomes among the other tropical birds. It is relatively common in the real world, but due to the role it will be playing, it will have the same rarity as the wolf mob with 16.6% of all spawns being a baby. The height of the bird will be 0.7 blocks and the width 0.5 as an adult, and as a baby the height will be 0.5 blocks and the width 0.25 blocks.
Combat: When it is wild it will have 12 hp posing as a strong mob, and when tamed it will have 24 hp making it even stronger. It will also be a neutral mob, dodging arrows with ease by spinning and circling around in the air. The greater the difficulty the harder it is to hit it with a bow or a trident. They attack by swooping down in order to take away 3 hp from the player. Oh did I mention it can fight mobs? The mobs it can fight are skeletons, zombies, zombie pig men, chicken, pigs, tropical fish and tropical birds. It's sharp talons deal 4 hp damage to each one of these mobs. Now what I am about to say does not apply in real life, but in mine craft wolves are the hawk's natural Allie. If a wolf is fighting within the sight radius of a hawk, the hawk will assist in taking down that enemy and vice versa, imagine having these two mobs tamed. On death, an untamed Ornate hawk-eagle will drop 1-5 exp, while tamed it will decrease to 0-1.
Taming: Hawk's cannot be tamed like a wolf or an ocelot, but instead it will follow you as long as you have food in hand. It likes to eat cod, raw chicken and eggs so it would be nice to have these on hand. But what really separate them from feeding other mobs is that you can reset the location of where they consider home. By simply crafting a bird fence which will be one fence and one leather, the hawk will always land on it. If you ever have more than one hawk, it would be nice to have each one go to a specified post. You can do this by giving the bird fence a name through anvil, and giving the hawk the same name through name tags, which can be crafted by one paper in the bottom left corner, ink sac in the middle box and one string in the top right corner of the crafting table.
More Background: Now you might be wondering, is all the work required to ultimately tame a hawk worth it? Well here is why it is: During the night they will fly up high and survey the area in order to warn you of any hostile mobs near, and one out of the ten times they will bring back a weapon or piece of armor from a hostile mob near by. They also serve as a distraction for skeleton, since just like players they are their natural enemy, but the rivalry between the hawks and the skeletons makes the hawks have a one out of four chance to gain priority over the skeleton's focus meaning you can get in a couple of hits making fighting a skeleton less annoying. Also, there is a one out of seven chance the hawk can land on your head or shoulder showing a high amount of friendship towards you. This will only last for 3 seconds because soon the hawk will have to fly off in order to find food for itself, which it does every 15 seconds, unless hostile mobs are nearby. Hawks are also very smart, being able to see glass and when it is low on health it will know the best option for it is the fly away. They also have a chance when swooping down to attack a creeper to decapitate it giving you a creeper head but this is only a one out of thirty chance of it happening. This will lead to the creeper dying without an explosion. Also, do not try to back stab the hawk, since it is not 100% tamed, any signs of life threatening abuse will cause it to fly away and disappear. Oh, and no it will not return to where it originally spawned. Speaking of spawn, if you ever die in the over world the hawk will be able to find you and return 1-5 items over a time span of 10 minutes. It will avoid the useless items such as dirt, but also cannot carry heavy stuff such as diamonds (except for tools). Oh, and blocks cannot be carried, so any iron ore will be left.
