The bodies of the barn swallows, which are attached at the hip by skin and possibly muscle tissue, are being sent to the Smithsonian Institution for examination and confirmation, Arkansas wildlife officials said Friday.
The birds, found by a landowner in White County, fell out of a nest as a healthy sibling flew off to learn how to hunt with its parents, Rowe said. The birds first appeared to have only three legs, but further examination found a fourth leg tucked up underneath the skin connecting the pair.
