About These Birds
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
Bryan's Shearwater
27 cm. Small shearwater; dark brown above, white below with dark smudging on flanks. Known from only a few specimens collected at Midway Atoll; Critically Endangered or possibly extinct. No confirmed breeding in decades; one of the least-known shearwaters.
