Society Kingfisher
Todiramphus veneratus
A medium-sized kingfisher. Male of the Tahiti form is dark green above and white below with a paler aquamarine eyebrow. Male of the Moorea form is light tawny-brown above and whitish below with a pale collar. Female has a dark brownish chest band and is overall browner than male. Found in forested habitats up to 300 meters of elevation on Moorea and 1700 meters of elevation on Tahiti. Overlaps with Chattering Kingfisher, but lacks the white eyebrow of that species and is overall less pale and darker green. Typical rattling “ki-ki-ki-ki-ki” is commonly heard.

分类信息
The Society kingfisher was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other kingfishers in the genus Alcedo and coined the binomial name Alcedo venerata. Gmelin based his description on the "venerated kingsfisher" that had been described in 1782 by the English ornithologist John Latham in his multi-volume A General Synopsis of Birds. Latham had access to a specimen in the Leverian Museum which he erroneously believed had come from the "Friendly Islands", now Tonga in western Polynesia. Latham noted that the Polynesians revered and protected kingfishers. The specimen would have been collected during either James Cook's second or third voyages to the Pacific Ocean. Three water-colour drawings survive from Cook's voyages that are believed to depict the Society kingfisher: one by the naturalist Georg Forster painted on Cook's second voyage, one by William Wade Ellis painted on Cook's third voyage and one by the artist John Webber that was also painted on the third voyage.<p>The Society kingfisher is now one of 30 species placed in the genus Todiramphus that was introduced in 1827 by René Lesson. The word Todiramphus combines the genus name Todus with the Ancient Greek rhamphos meaning "bill". The specific epithet veneratus is Latin meaning "venerated".<p>Two subspecies are recognised:

White-backed Mousebird
Colius colius
A mostly grayish, buff-bellied mousebird with a long tail, black-tipped silvery bill, and back with diagnostic white patch flanked by two dark stripes. Small groups inhabit coastal shrublands, farms, and semi-desert; prefers drier areas. A cooperative breeder; chicks from the prior year will remain with parents and help feed and protect the new brood. Sings a melancholic “cheee-wee-wee-wiit”; also produces a distinctive series of buzzes and clicks.
Blackthroat
Calliope obscura
A somberly-colored robin which breeds in dense bamboo thickets. Male is slate-gray above (only a hint of blue may be detected in good lighting) with a white belly and black bib. Female is brown with a paler belly and a rusty-brown tail. Forages on the ground and in low bushes like most other small robins. Shy, usually keeping close to cover. Song is a series of distinct, separated phrases consisting of bright fluid warbling, high buzzy trills, and buzzy warbling.
Sapphire-rumped Parrotlet
Touit purpuratus
Small parrot of lowland rainforest and savanna regions; more common in areas with sandy soils, but rarely seen well. Usually in small flocks that fly rapidly through or above canopy, settling into trees where they essentially disappear. When perched, best identified by small size and combination of blue rump and red outer tail feathers. In flight, gives drawn-out, complaining call note, very unlike calls of other parrots in range. Feeds on fruit.
