Some wings for you all, as well as “just bones advanced challenge”:
Bird A has a wing chord of about 21cm, and was found by John and Wendy Stanton in North Carolina last month. Bird B, “Bonesey” to you, is what it is. Jerry Golub, whose New Jersey beach was obliterated by Hurricane Sandy is now wintering in Florida and found this partial skeleton there. He reports that the long bone was about a foot long. Believe it or not, it is possible to make a species identification from this, so give it a go, my dear readers!
