Fairy Prion vs Antarctic Prion: common questions
Which one is the smallest prion?
The fairy prion is the smallest of all prion species, noticeably smaller than the Antarctic prion, which grows somewhat larger.
Which one feeds in the largest flocks?
The Antarctic prion feeds in the largest flocks, sometimes gathering in the thousands to exploit concentrated patches of plankton, a scale of flocking not specifically documented for the fairy prion.
Do both prions visit their colonies only at night?
Yes, both species visit their breeding burrows only under cover of darkness, a shared strategy that helps each avoid predatory skuas and gulls patrolling their colonies during the day.
