Merging and baked Sample images into one image texture

So im Making this bird on blender , and ive got a bunch of different images of birds from google, so i made different materials and assign them to parts of the birds mesh , cause i wanted samples from different bird images , and combined it to this one bird , So then i wanted to Bake all those into one image , but when i add a new material , and a image texture to it ,i have it selected with the blank image and start baking , it wont bake to the blank image i made , it baked and replaced those sample images instead of baking all of it into this Blank image
