Chattering Kingfisher
Todiramphus tutus
A pale kingfisher with clean white underparts, neck, and forehead and a light greenish-blue cap, cheek, and upperparts. A thin dark line extends from behind the cheek around the neck. Prefers primary forest, especially around highland streams, but adaptable, occurring in a variety of habitats. Overlaps with Society Kingfisher, but differs in its white eyebrow and brighter, paler plumage. Voice is a repeated “kee-kee-kee-kee” running into a raucous chatter.
识别特征
It resembles the collared kingfisher but is smaller and lacks any rust colour in the plumage. The breast and throat is white, and the back, wings and crown are blue-green (although the crown of the Atiu subspecies is almost entirely white). It can be told from the Tahiti kingfisher by the complete white collar.
分类信息
The chattering 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 other kingfishers in the genus Alcedo and coined the binomial name Alcedo tuta. Gmelin based his description on the "respected kingfisher" that had been described in 1782 by the English ornithologist John Latham in his multi-volume A General Synopsis of Birds. Latham gave the locality as Otaheite (Tahiti) but did not specify how he had access to a specimen. Latham noted that the Polynesians revered and protected kingfishers. The specimen (or specimens) would have been collected during either James Cook's second or third voyages to the Pacific Ocean. The society kingfisher (T. veneratus) is present on Tahiti but it is doubtful whether the chattering kingfisher ever occurred on the island in historical times. The chattering 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 tutus is Latin meaning "revered".<p>A molecular phylogenetic study published in 2015 found that the chattering kingfisher was closely related to two other species that are endemic to islands in eastern Polynesia: the Niau kingfisher (T. gertrudae) and the society kingfisher (T. veneratus).<p>Three subspecies are recognised:

分布与栖息地
Its natural habitats are tropical moist lowland forests and tropical moist montane forest. The species prefers primary forest in montane valleys, but will move into secondary growth and old plantations. The species has an uneven distribution. Nevertheless, it is not considered threatened with extinction by the IUCN.

Micronesian Myzomela
Myzomela rubratra
A tiny bright red myzomela with dark blackish wings and tail, a blackish patch in front of the eye, and a decurved bill. Found widely in most habitats, mostly along forest edge and in scrub. The only myzomela in Micronesia. Voice is a mix of wheezing upslurred whistles and complex chattering and squeaking.
White-throated Flycatcher
Empidonax albigularis
Rather drab, small flycatcher of marshes and semiopen areas with bushes and hedges; winters mainly in lowland marshes. Flicks tail upward when perched. Looks similar to several other species in the genus Empidonax. Best identified by its distinctive call: a burry, slightly sneezy “rreeah,” quite different from Willow Flycatcher, which often occurs alongside White-throated in winter. Also note the whitish throat, buffy wingbars and flanks, and the lack of a distinct pale eyering.
Red-breasted Chat
Granatellus venustus
Easily overlooked, warblerlike bird of tropical forest in lowlands and foothills of west Mexico and extreme western Guatemala. Hops around, mainly at low levels in tangled understory, often fanning and waving around its rather long, white-edged tail. Male is striking, with red breast and bold black-and-white head pattern. Female-plumaged birds are seen more often and can be puzzling, but note buffy face and breast with a dark beady eye, mostly grayish upperparts, and white-edged tail.
