The reference photo I found at the Morguefile archive, identified this as a Green Heron. I'm not sure if is because there wasn't a spec of green on the bird. I think this may have been the hardest bird yet because the proportions are so strange!
Done using Mijello Mission Gold Pure Pigment Watercolor Set, Daniel Smith's Iridescent Blue Sapphire and Silver Black Velvet Brushes Round size 6 and size 16.
This bird was done in the Global Art Materials Field Watercolor Artist Journal Hand Book, 7 by 10-Inch that I'm using for the '52 Weeks of Watercolour Birds'.
