Fly like a bird

I hadn't done origami for a long time but it was a pleasant surprise that the challenge Random Challenge of the Day #33 was selected nothing more and nothing less than this art by @khackett so let's get down to work

Ideally, do it with a square of paper of about 15 cm, but I only got one about 23 cm so I'll just make a big ass bird

That's a big ass bird

In the end I got a smaller square so I made a little bird that would accompany the big one

I hope you all like it and make your own birds
