About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
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.
