Southern Fulmar

45–50 cm, wingspan 115–120 cm. Pale grey above, white below with dark wingtips; pink bill with blue tube-nose. Breeds Antarctic cliffs; ranges across Southern Ocean to about 35°S after breeding. Feeds on fish, squid, and krill by surface-seizing. Highly colonial; migratory.

Balearic Shearwater

30–38 cm. Brown above; variably dirty-white to brown below; often shows brown smudging on flanks. Breeds only Balearic Islands, Spain. Critically Endangered with fewer than 3,000 pairs; faces extinction. Migrates to NE Atlantic; threatened by predators, fishing bycatch, and tourist development.
