Azure Tit
Cyanistes cyanus
Frosty, pale bundle of joy. Nominate northern population is white with a shadowy black outlining of the cheek, bright blue-and-white striped wings, and a clean white breast. Central Asian and Central Chinese birds have a bright yellow patch on the breast. Prefers open wooded or shrubby areas, often in proximity to willow, birch, and various conifers. More common in open habitats in northern range. Forages actively, often within dense foliage, and can be surprisingly difficult to see well. Gives various high-pitched calls, including chips, trills, and rattles. Song is variable, and includes high whistles followed by a rattling stutter, as well as a series of cheery, repetitive two-note calls.
分类信息
For many years the azure tit was known as Parus cyanus. In 2005, analysis of the mtDNA cytochrome b sequences of the Paridae indicated that Cyanistes was an early offshoot from the lineage of other tits, and more accurately regarded as a genus rather than a subgenus of Parus.<p>The azure tit not infrequently hybridizes with the blue tit in western Russia; the resulting birds are called Pleske's tit (Cyanistes × pleskei) and were once considered a distinct species.<p>The population in central Asia, yellow-breasted tit (C. c. flavipectus or Parus flavipectus), is sometimes included as a subspecies of the azure tit.

Violet Crow
Corvus violaceus
An entirely blackish short-tailed crow. Has a subtle purplish sheen that is visible in only certain lighting conditions. Juveniles lack purple gloss. Inhabits forest, edge, and plantations in the lowlands and foothills. Singles, pairs, or small groups can be found in the canopy. Recently described from Seram, and perhaps also occurs on Ambon and Buru. Unmistakable, being the only crow on these islands. Gives an odd call for a crow: a nasal, trumpeting “errr.” Gives more crow-like sounds too, but higher-pitched than many sounds of the family, including a high-pitched, guttural “kreh-kreh…”.
Bahia Antwren
Herpsilochmus pileatus
Small, long-tailed antwren. Males resemble many other antwrens, mostly gray with a black cap, a long white eyebrow, and a black eye-stripe. Females have a streaked crown and a buffy forehead and underparts. Inhabits the middle levels and canopy of coastal forest (restinga), where it forages singly or accompanying mixed-species flocks. Sings a series of 4-7 notes that accelerate gradually and then decelerate slightly at the end.
Masked Apalis
Apalis binotata
A small, slender warbler with greenish upperparts and reddish eyes; gray crown and cheeks are separated from the black throat by a striking white moustache. Juvenile has a green crown and a yellow throat. Locally common at scattered locations in lowland forest below 1500 meters of elevation, preferring the lower strata of primary and secondary forest and scrub in clearings. Pairs give a continuous buzzy “dree-lip, dreep-lip, dree-lip” and a dry “strik-strik-strik.” Masked Apalis looks similar to some montane forest apalises, but Black-throated Apalis has a striking yellow-orange belly, and Black-faced Apalis, an Albertine Rift endemic, has a black crown and the moustachial streak reduced to a neck spot.
