I have since dabbled in it several times a year. A feather is a fascinating and frustrating canvas; care must be used not to split the rachis of the feather (and if you do, once there is paint on it it will never mend again). Correcting mistakes is often hard to impossible if you get paint in an area where you don't want it (one cannot lift the paint back off, nor scrub it, and over-painting ruins the appearance of the feather). Further, the size is tiny, the texture is great, and the surface is flexible. They are quite a challenge for me!
Barn Owl Profile, acrylic on 8" x 2" cockatoo tail feather, and Blue and Gold Macaw, acrylic on 7.5" x 1.5" Blue and Gold Macaw secondary wing feather, respectively.
These feathers were naturally molted (or shed) by healthy parrots in a bird rescue in Florida. The first is intended as a gift, while the macaw will be auctioned off with 100% of the proceeds going to Two Feathers Wildlife Center Inc., which is where the parrots these feathers came from reside. I will be posting more information on the auction once I have more details.
