Dead skua? Killed by cats? If the cats made friends, they probably would have given it sunglasses and a patch. If you don't understand this comment, go here.
After about ten more minutes of sitting, waiting, and wondering if the first baby skua was alive and the second rumored baby was underneath the adult skua, we started to head out. As we did, someone saw the baby skua moving and there was much rejoicing.
The baby skua is the small white ball in the top right quarter of the photo.
Baby skua giving us the stare down!
