Azure-naped Jay
Cyanocorax heilprini
Large blue-gray jay with a black face and piercing yellow eyes. Note the white-tipped tail. Found at forest edges, in wooded savanna, in second growth, and in white sand forests, avoiding the interior of humid forests. The “Campina Jay” subspecies of southern Amazonia, considered a species by some authorities, has a pale azure rather than dark purplish-blue breast, a paler uppertail, and two bare blue skin patches around the eye. The call is a loud, harsh “jeer,” similar to the call of Violaceous Jay.
识别特征
The back is dark brown, as are the upper sides of the wings and tail. The rear crown and nape are bright lavender blue. The front and sides of the head are black, with the feathers of the forecrown and forehead curled up and forwards in a short bushy crest. From the chin to the centre of the breast the bird is dark violaceous-grey. The lower breast and belly are violaceous, fading to white on the lower belly and vent. The eyes are pale to yellowish-white and the bill, feet and legs are black.
分类信息
The Azure-naped jay was first described by Alan F. Gentry based on a single specimen, marked as a male, from the T. B. Wilson Collection of the Academy of Natural Sciences of Philadelphia.<p>The genus Cyanocorax comes from the Ancient Greek kuanos (dark blue) and korax (raven). The species epithet heilprini honours Gentry's friend, Professor Angelo Heilprin.There are two identified subspecies:

Squat ground-dwelling dove with shimmering green wings. Note chocolate-brown body. Found in forest and forest edge, where it forages on the ground; often flushed at close quarters with a loud wing-clatter. Usually solitary, occasionally in flocks or small groups.

Mindoro Island-Thrush
Turdus mindorensis
Little-known thrush endemic to the Philippine island of Mindoro, where it is restricted to montane forest generally above 1200 meters. Handsomely patterned, with a gray head, black back and tail, and dark rufous sides. Also note bright orange bill, eyering, legs, and feet. Behavior poorly known, but likely forages at all levels of forest, much like other Island-Thrushes. Vocalizations obscure; other Island-Thrushes in the Philippines give beautiful songs consisting of warbles and trills, as well as explosive rattles and chup notes.
