Thanks Zach and Jane- appreciate your thoughts. I noticed the thin legs/feet especially, but felt the head was a bit large. Perhaps because of the extended neck photo. I wasn't aware of the "bug-eyed" feature for Sharpies, so that's helpful. I think I will report it as a sharpie and see if I get corrected by the ebird "police". ;).
