I’ve made a few. My kids really like them.
I made the pattern by marking up a folded bird, unfolding it, scanning it, then assembling pieces of various photographs. The wings are my least favorite part. I am pleased that the bottoms of the wings match up as well as they do, though.
Maybe eventually I’ll put together folding instructions, as an exercise in photographic documentation. In the meantime, you can use the wikihow instructions, although they don’t include the little beak fold. I’m also considering refining the pattern further.
