I have been experimenting with different ways of getting the largest wing span % of the width of the starting square. This Cape Vulture, with feathered wings, talons and "closed" front and back, has a wing span of 72%.

When male ostriches compete fro territory and females with an aggressive display, they run and "flap" their wings. That is what I wanted to capture in this design.

When I first saw a photo of this beautiful bird, I just had to design one. The colour-changes were a challenge, as the birds have a white tail, legs and shoulders, as well as a large beak that I wanted to depict in a colour-change. From an uncut square, with a 50% wing span relative to the starting width of the square.

From an uncut square and a base similar to the Steller Sea Eagle. I changed the proportions many times to achieve this result, where the white neck feathers fan out onto the shoulders. The wing span is 50% of the length of the square.
