"Petrels are aloft, sooty terns afloat and Mother Carey's Chickens roost on the rigging."

All forms of sea bird. Mother Carey's Chickens are storm petrels, and Mother Carey an ancient nautical reference to the old crone who controlled inclement weather. The name petrel comes from the Latin name for Saint Peter, owing to the fact that hovering petrels appear to be walking on water. The 'purplish moths' were probably Othreis fullonia, which populate the South Pacific Islands and feed on fruit.
