Hawaii Elepaio
Chasiempis sandwichensis
A small flycatcher of forested habitats on Hawaii Island. Adults have white wingbars, rump, and tail tips. More common and widespread in native forest at higher elevations, but occurs at lower elevations in some areas where forest remains. Bold and curious; not afraid of people and may follow hikers. Often holds tail cocked up at an angle. Male song is a shrill “El-eh-pie-oh” for which the species is named. Both sexes give a variety of calls and scolding notes. May respond to pishing and squeaking.
识别特征
The Hawaiʻi ʻelepaio (Chasiempis sandwichensis), also Hawaiian ʻelepaio, is a monarch flycatcher found on the Big Island of Hawaii. Until 2010, all three ʻelepaio species, the Kauaʻi ʻelepaio (Chasiempis sclateri), the Oʻahu ʻelepaio (Chasiempis ibidis) and this species were considered conspecific.
分类信息
The Hawaiʻi ʻelepaio was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa sandwichensis. Gmelin based his description on the "sandwich flycatcher" that had been described in 1783 by the English ornithologist John Latham in his book A General Synopsis of Birds. Latham had examined a specimen from the Sandwich Islands (now the Hawaiian Islands) in the collection of the naturalist Joseph Banks. The specimen would have been collected between 17 January and 22 February 1779 near Kealakekua Bay on the island of Hawaii during James Cook's third voyage to the Pacific Ocean. The Hawaiʻi ʻelepaio is now placed in the genus Chasiempis that was introduced in 1847 by the German ornithologist Jean Cabanis. The species was formerly considered to be conspecific with the Kauaʻi ʻelepaio (Chasiempis sclateri) and the Oʻahu ʻelepaio (Chasiempis ibidis). The genus name is derived from Ancient Greek khaskō meaning "to gape" and empis meaning "mosquito" or "gnat".<p>Three subspecies are recognised which differ in their ecological requirements and head coloration (see also Gloger's Rule):

Rufous-tailed Robin
Larvivora sibilans
Combination of strongly scaled breast, rufous tail, and round-headed appearance distinguish this species from others in its range. Small and skulky, sticking to dense shrubbery and shorter trees in its forest breeding grounds, where it favors dense, moist growth in lowland broadleaf forests. Often bolder on migration, emerging into forest edges and gardens. Song is distinctive, a long, wet-sounding descending trill.
White Stork
Ciconia ciconia
Large, mostly white stork with black flight-feathers and conical red bill. Breeds in open farmland and wetlands, with bulky stick nests conspicuous in trees and often on buildings. In nonbreeding season forages in open areas such as grasslands and agricultural areas. Flies with neck and legs outstretched, and strong, deep wingbeats interspersed with glides. Also soars on thermals; flocks migrate during daytime, often high overhead.
Lesser Antillean Swift
Chaetura martinica
An aerial feeder that is typically found over highland forests in flocks of up to forty birds; sometimes feeds at lower altitudes, particularly during inclement weather. Its stubby dark-gray body and rapid, shallow wingbeats eliminates all swallows. Short-tailed Swift is similar, but has a gray vent and gray rump, which contrasts more markedly against its dark body than Lesser Antillean Swift. Very rarely found when not flying. Call is a high, sharp twitter.
