Chestnut-tailed Starling
Sturnia malabarica
Pale-headed starling with dark-tipped wings and an orangish belly and rump. Bill is distinctively colorful: blue with a yellow tip. Inhabits open forests and forest edge, as well as agricultural areas and village outskirts. Like other starlings, social and raucous, often flocking together while noisily churring and whistling. Frequently perches up on exposed perches such as snags and utility lines, but also forages extensively on the ground. Native to southern Asia; introduced to Taiwan.
Identification
The adults have a total length of approximately 20 cm (7.9 in). They have grey upperparts and blackish remiges, but the colour of the remaining plumage depends on the subspecies. In the nominate subspecies and blythii, the underparts (incl. undertail) are rufous, but in nemoricola the underparts are whitish tinged rufous, especially on the flanks and crissum (the undertail coverts surrounding the cloaca). The nominate and nemoricola have a light grey head with whitish streaking (especially on crown and collar region). Both subspecies have white irises and a yellow bill with a pale blue base. The sexes are similar, but juveniles have whitish underparts and just chestnut tips to the tail feathers.
Taxonomy
The chestnut-tailed starling 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 thrushes in the genus Turdus and coined the binomial name Turdus malabaricus. Gmelin based his account on the "Le Martin Vieillard de la côte de Malabar" that had been described in 1782 by the French naturalist Pierre Sonnerat in his book Voyage aux Indes orientales et à la Chine.<p>The chestnut-tailed starling was formerly placed in the genus Sturnus. A molecular phylogenetic study published in 2008 found that the genus was polyphyletic. In the reoganization to create monotypic genera, the chestnut-tailed starling was one of five starlings moved to the resurrected genus Sturnia that had been introduced in 1837 by René Lesson.<p>Two subspecies are recognised:<p>Both the nominate subspecies and nemoricola are known to perform some poorly understood movements (e.g., S. m. malabarica has been recorded from Pakistan and in central and southern India).<p>The taxon blythii is now usually (e.g. Rasmussen & Anderton, 2005) considered a valid species, the Malabar starling or white-headed myna (Sturnia blythii), instead of a subspecies of Sturnia malabarica. As S. m. malabarica only visits the range of blythii during the non-breeding period (winter), the two are not known to interbreed. However, a molecular study found the genetic divergence between S. blythii not significantly greater (between 0.2% and 0.8%) than between the sisters S. m. malabarica of northern India and S. m. nemoricola of Burma and Vietnam.

Other Birds
Eye-ringed Parrotbill
Suthora ricketti
Gregarious long-tailed little bird. Restricted to southwestern China and adjacent northern Myanmar, where it inhabits grassy and scrubby areas, as well as bamboo stands and secondary growth, in mountains and foothills. Note the warm reddish-brown head, pale eye, darker brown wings and tail, and streaked white throat. Similar to Brown-winged Parrotbill (with which it was formerly considered one species), but note paler eyes and more contrastingly streaked breast. Moves about noisily through dense vegetation, twittering and chattering constantly.
Malagasy Sacred Ibis
Threskiornis bernieri
Large white ibis with fluffy black feathers across the rump and a black head. A good view reveals a pale eye in adults. Immatures can have a dark eye and white on the throat. In flight, the wings are completely white. Rare and local resident of western Madagascar and Aldabra, in the Seychelles. Found on coastal mudflats and sandy shores, in mangroves, and on the banks of brackish rivers, ponds, and lakes. Rarely uses freshwater habitats. Very similar to African Sacred Ibis, but separated at all ages by the lack of black wingtips in flight. Adults further separated by their pale eye.
Crowned Chat-Tyrant
Silvicultrix frontalis
Small flycatcher found in the Andes from northern Colombia to Bolivia. Brown above and gray below. Very obvious eyebrow is mostly white; changes to yellow in front of the eye. In eastern Andes of Colombia entire eyebrow is white. Northern populations have plain brownish wings; birds from central Peru to Bolivia, sometimes split as Kalinowski’s Chat-Tyrant, show prominent cinnamon wingbars. Singles or pairs are found in understory and mid-levels of upper subtropical and temperate forest and scrub from around 2,600 to 3,800 m, usually separate from mixed-species flocks.
