I have posted a photo of bird radius I am having trouble identifying to the BoneCommons website http://www.alexandriaarchive.org/icaz/icazForum/viewtopic.php?p=982#982 username: ZOOARCH password: bones. This is a bird radius from a Middle Woodland site in Illinois, I suspect that it is a trumpeter swan but I do not have the comparative material or measurements on hand. This measures 29.55 cm in length and 0.99 cm in diameter at midshaft; that would put it outside of the published range of whistling swan (23.1 to 24.9 cm) in Gilbert et. al.'s Avian Osteology. Unfortunately there are no measurements for trumpeter swan which this probably is, or of mute swan which this probably is not -- if anyone has measurements for these species it would be greatly appreciated! Thanks, Rex
