Labors of Love has a series of clip-on bird canvases that come with feathers. You can see them on their website. The birds are a double-sided canvas that comes with the clip and feathers for the tails.
Tony Minieri is writing stitch guides for at least some of these canvases. You can almost certainly get them from In Stitches in Atlanta. There is a photo of some finished birds perched in an artificial tree on their home page currently.
