Przevalski's Pinktail

Slender gull-like seabird; the smallest of the three jaegers. Breeds on Arctic tundra; spends the rest of the year at sea. Difficult to separate from other jaegers, especially Parasitic. Breeding adults have an exceptionally long, pointed tail. Also note uniform brownish back contrasting with dark flight feathers, limited clean black cap, and pale yellow on the side of the neck. Immature birds have an attractive scaly pattern on wings and vary from dark brown to a pale grayish white. At all ages, note buoyant, tern-like flight. Typically shows white shafts only on two outermost wing feathers (fewer than other jaegers). Bill is shorter and proportionally thicker than other jaegers. Jaegers chase other birds and steal their food.

A small bird with a long blue tail that is held cocked. Breeding males are usually brilliant sapphire blue with bright white wing patches. Females and nonbreeding males are very plain pale gray, and the patch between the eye and bill (lores) is also pale (compared to Purple-backed Fairywren which has very dark reddish lores). This species is typically found in very open and arid country with sparse bushes, where it often perches on the very top of bushes. Its call is a very fast trill.

Very small tanager, widespread and common in lowlands and foothills of northern South America. Male is indigo-blue with narrow black mask, black throat, and black wings. Note long decurved bill and yellow legs to separate from other honeycreepers in most of range. Female much different: she is mostly green with pale streaking on underparts, a grizzled buffy-brown face, and a blue mustache stripe. Extremely similar to Shining Honeycreeper, but very little range overlap. Male Shining has larger black throat patch and slightly shorter bill; female has duller, grayer crown and less buffy face. Usually in small groups, often accompanying a mixed-species flock in the canopy. Found in forests, edges, and gardens.
