The scarlet tanager is a bright bird, which would be perfect in a texture pack to inhabit your jungles and forests. Please manually spawn them in wherever habitat you want them to go to in creative mode, and then they would most likely stay in that habitat. I recommend replacing the red parrot (Scarlet macaw) with this bird, but it's a skin texture that could go on any parrot in Minecraft. These birds are rare and secretive, so spawn them in groups of 2 or one in spruce or oak forests.
