Dark-rumped Rosefinch

A tiny, all-dark swift. Flight is fast, fluttery, and batlike. Usually observed flying continuously along ridges or over the forest canopy. Native to the Mariana Islands; introduced to Hawaii from Guam in the 1960s. In Hawaii, occurs only in the mountains of Central Oahu, seen primarily in Halawa Valley and the adjacent Aiea Loop Trail.

Colorful migratory parrot with long red pointed tail. Breeds in Tasmania and migrates to southeastern Australia in autumn and winter. Found in a wide variety of forests, where its presence is largely dictated by flowering eucalypts on which it feeds. Adult bright green with red and yellow on face and a subtle blue-purple crown patch. In flight, shows bright red underwings and long red tail. Compare Scaly-breasted Lorikeet, which has shorter green-yellow tail. Calls include a sharp rattling as well as short, piercing squeaks.

Plump, rock-loving shorebird with slightly droopy bill. Most often seen in nonbreeding plumage, which is fairly dark gray with spotted underparts. Namesake purple sheen (mostly on back, scapulars, and tertials) only visible at close distance in good light. Legs and base of bill usually bright orange. Messy-looking breeding plumage is darker and more heavily marked, with limited rusty tones on upperparts. Largely inaccessible breeding range on high Arctic tundra; most often seen in northern Europe, Spitsbergen, and Iceland. Winters at slightly lower latitudes, regularly south to the mid-Atlantic region in North America and the Iberian Peninsula in Europe; found in flocks on rocky coastlines and jetties pounded by heavy surf.
