Rachel's Malimbe

A very large, grayish-brown owl with yellow eyes and distinctive ears. Note the fine barring and dark streaks on the pale underparts, and white patches on the shoulders. In flight, wings and tail are strongly barred below. Perches in tall trees, usually near a water body, where it waits for birds and mammals to pounce upon. The call is a distinctive series of low, guttural notes that increase in volume and speed before trailing off towards the end.

A tiny swift with glossy upperparts (many forms showing a greenish-blue tinge), a white belly, and a bat-like, fluttering flight action. Some forms show a white rump. Occurs over most habitats throughout range, often within flocks that regularly mix with other swiftlet species. Away from nesting colonies, always seen in flight. Smaller and shorter-winged than Uniform, Papuan, Bare-legged, Mayr’s, Mountain, and White-rumped Swiftlets. Further distinguished from those species and from Edible-nest, Sulawesi, Seram, and Halmahera Swiftlets by white belly and flight action.

Huge albatross of the Southern Ocean; breeds mainly on Chatham Islands in New Zealand, but ranges widely. Especially numerous in Humboldt Current off western South America. Easily separated at a distance from smaller albatrosses by white back. From the Wandering Albatross complex (including Snowy, Tristan, Antipodean, and Amsterdam Albatrosses) by uniformly dark upperwings at all ages with otherwise clean white appearance (including mostly white tail, occasionally with small black markings). This combination of features is never shown by Wandering-types, and Northern Royal never has dirty brownish markings on head and body or a mostly black tail. At close range, note the diagnostic narrow black “lips” on cutting edge of bill, lacking on Wandering-types. Also note slightly longer, thinner bill and shallower forehead, which give Northern Royal a “snoutier” look than Wandering-types. Very similar to Southern Royal Albatross; best separated by uniformly dark upperwings, especially on the leading edge. Youngest Southern Royals can also have dark upperwings with very narrow white leading edge; can require close scrutiny or good photographs to identify with confidence. Range averages further north than Southern Royal, but some overlap.
