Silvery-throated Jay
Cyanolyca argentigula
A small, striking jay with a very limited range in the highlands of Costa Rica and Panama. Unmistakable: mostly dark midnight-blue, brighter on the wings, with pale silvery throat and thin eyebrow. Sexes similar. Uncommon to rare in oak forests from around 2,000–3,200 m. Found in pairs or small flocks. Listen for harsh calls, typical of a jay.
Identification
The silvery-throated jay is a distinctive small jay, unlikely to be confused with any other bird found within its range. The sexes are similar, with the adult being about 26 cm (10 in) in length including the long tail. The head is black with a narrow but obvious white supercilium, and it bears an inconspicuous crest of short stiff feathers on the forehead. The throat and breast are silvery-white, sometimes with a violet sheen. The mantle, neck and sides of breast are black which gradually blends into the dark purplish-blue of the rest of the plumage. The upper surfaces of the wings and tail are a brighter, paler shade of blue and the undersides are blackish. The irises are deep red and the bill and legs are black. The plumage of the juvenile is duller and lacks the white on the head.

Himalayan Cuckoo
Cuculus saturatus
Visually indistinguishable from Oriental Cuckoo. Adult male is gray above with a black-and-white-barred belly and a dark gray tail; females usually look similar, but some (known as hepatic morph birds) have cinnamon-brown upperparts with black barring throughout. Intermediate in size between Common and Lesser Cuckoos; distinguished from both species by buffy (not white) under-tail feathers and from Lesser Cuckoos by yellow iris. Song is a series of five notes, with the leading note being sharper and more distinct than the four that follow; compare with Oriental Cuckoo’s series of mellow paired notes. Breeds in a wide range of different lowland and hill forests; also more open habitats outside of breeding season.

Himalayan Rubythroat
Calliope pectoralis
Shy inhabitant of thickets and dense grassy areas from subalpine scrub to above treeline. Male is gunmetal gray with a white brow, bright orange throat, and a black patch extending from the face down to the breast. Very similar to the closely related Chinese Rubythroat, which has a white moustachial stripe. Chinese Rubythroat female averages browner than female Himalayan, but is best identified by range; Chinese breeds in central and south-central China, while Himalayan breeds along the Himalayas, in Xinjiang, and in Central Asia. Female Himalayan has a weaker eyebrow than female Siberian Rubythroat, and is darker overall.

European Starling
Sturnus vulgaris
Stocky and dark overall with short tail and triangular wings. A close look reveals beautiful plumage: in breeding season, look for purple and green iridescence and a yellow bill. In winter, shows extensive white and buffy spots over the entire body. Juveniles are plain grayish-brown; note bill shape. Native to Eurasia; introduced extensively across the globe. Often abundant, gathering in large flocks in open agricultural areas and towns and cities. Makes a variety of squeaky vocalizations, and often mimics other species. Visits feeders, where it is often aggressive towards other birds.
