In the thread titled 'Last of the 2013s' I had a photo of some emerging (cherry-head) red-foots. Well, as they came out of their eggs I discovered that one possessed a nuchal scute--something red-footed tortoises are not supposed to have.
This is the fourth individual hatchling from this year with a nuchal and the first to come out of this particular female. Clearly, it is one of the males that carries the gene for this retro trait.
