Screechers

Screechers would be a passive, bird like nether mob that drops feathers when killed. They are mortal enemies with hoglins and will kill them on sight. They also can be breed using warped and crimson roots or pork. You can also feed them string and when you do, they have a 10% chance of hacking a diamond from there mouths! They would be a little bigger than chickens and  would not fly. They would be blue and green with a head crest.
