These three birds are Tufted Puffins. Unlike the Horned Puffin of the west or the Atlantic Puffin found in the Northeast, these birds prefer to nest on cliffs with a bit of grass or other foliage. So in the same area you may see Horned Puffins nesting on bare rock and Tufted on tiny outcrops of grasses almost next to each other. Your Tufted is also easily noted for the black belly while the other two are bright white. All of them are neat with colorful outsized bills.
