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.
Persian Shearwater
30–32 cm. Dark brown above; white below with dark smudging on flanks and vent. Breeds islands in the Arabian Sea and Persian Gulf region. Ranges in NW Indian Ocean; poorly studied. Closely related to Audubon's Shearwater complex; feeds on fish and squid.
