Black-cheeked Ant-Tanager
Driophlox atrimaxillaris
Large tanager usually found close to the ground. Male is sooty gray with black face and bright red throat that bleeds onto chest. Red crown not usually visible. Females have paler buffy-orange throat. Usually seen in small flocks as they forage through the forest understory. Listen for harsh scolding notes that might cue you into a flock.
识别特征
Based on a small number of specimens, the black-cheeked ant tanager is 18 to 19 cm (7.1 to 7.5 in) long and weighs 36.2 to 48.9 g (1.28 to 1.72 oz). The male's upper parts are dark gray with a red tinge, and it has a (usually invisible) orange-red crest. The face has a diffuse black "mask". The throat is bright salmon orange that transitions through darker salmon to dark gray with a pink tinge on the belly. The female is similar but duller and its crest is smaller.
分类信息
The original description of the black-cheeked ant tanager assigned it the binomial Phoenicothraupis atrimaxillaris and placed it in family Thraupidae, the "true" tanagers. Genus Habia was later shown to have priority so the species was renamed to its current binomial. In the early 2000s, DNA analysis revealed that all the members of Habia were more closely related to the cardinals, so they were moved to family Cardinalidae.

分布与栖息地
The black-cheeked ant tanager is found only on Costa Rica's Osa Peninsula and the adjoining eastern shore of Golfo Dulce. (One wandering individual was captured more than 70 km (43 mi) inland.) It inhabits well-developed understorey in lowland forest, riparian woodlands, and older secondary forest. It stays in the forest interior and shuns edges and open habitat. In elevation it ranges up to approximately 300 m (980 ft).

行为
The black-cheeked ant tanager is primarily insectivorous, though it also eats fruits and small vertebrates.<p>The black-cheeked ant tanager has been documented nesting between January and March. It builds an open cup nest fairly low in understorey vegetation. All known clutches were of two eggs. The species appears to nest cooperatively, as three adults have been documented attending nestlings.<p>The black-cheeked ant tanager's dawn song has been variously described as "whistled phrases...chonk TWEEah, chonk TWEEah" and a "clear, mellow, whistled tu-see, tu-see or tu-seeur tu-swee tu-seeur" [1]. It has a variety of calls such as [2] and [3].

White-naped Pigeon
Columba albinucha
A dark maroon-gray pigeon with a hind-crown and nape that are white in the male and gray in the female. At close quarters the bill can be seen to have a black base with a red-yellow tip, and the legs are reddish-purple. In flight the tail has pale-tipped corners. A scarce and localized resident found in pairs in the canopy of lowland and sub-montane forest in isolated populations in the Albertine Rift and Cameroon. Vocalizations are poorly documented, but reputed to be similar to those of Rameron Pigeon, which is larger than White-naped with a yellow eye-ring, bill, and feet, white speckling on the wings, and no white on the head.
Kerguelen Shag
Leucocarbo verrucosus
An attractive Southern Ocean crested and pied cormorant with pinkish feet, orange-buff warty caruncles on forehead, and a blue eye-ring, but without white wingbars. Juvenile is duller, lacking facial ornaments. Restricted to a single subantarctic island, Kerguelen, where it is the only cormorant and is commonly seen foraging in inshore waters. Although they do not overlap in range, most other Southern Ocean “blue-eyed” shags are larger, with whiter sides to the head, and many have white wingbars. Call is a grunting wheeze.
Temminck's Sunbird
Aethopyga temminckii
Medium-sized sunbird of foothill and montane forests; most often seen hanging around flowering trees and bushes, especially mistletoe. Male is blinding crimson with a white belly, a long crimson tail, and a dark moustache stripe. Male Crimson Sunbird is similar but lacks the red tail and white belly of the male Temminck’s. Female Temminck’s is very plain and difficult to distinguish from other sunbirds; watch for a distinct gray wash on the head, a white belly, and a faint russet tinge to the wings and tail. Sings a thin, soft “tsi-tsi-tsi’.
