Burnished-buff Tanager
Stilpnia cayana
A common tanager of savannas, forest borders, woodlands, and gardens. Often seen in pairs or with other species at fruiting trees, but usually not with mixed-species flocks. Males have a black face, throat, breast, and belly that is flanked by buffy sides. The crown and back are also buff and the wings and tail are dark-green. Females are buffy below with greenish back and wings, a pale throat, and a faint mask. The northern subspecies has a black mask (lacking the black throat and belly) with a violet gray throat and buffy belly.
识别特征
There are several subspecies of the burnished-buff tanager, them falling into two main groups: The northern and western cayana group, and the southern and eastern flava group (the subspecies huberi from Marajó Island is intermediate between the two main groups). Males of the cayana group have an orange-rufous crown, black mask, and cream underparts distinctly tinged blue on the throat and chest. Males of the flava group have an orange-buff crown, and buff underparts with a black patch extending from the mask, over the throat and central chest, to the mid-belly. Males of both groups have turquoise wings and tail. Females are duller than the males, and have black restricted to a poorly demarcated "shadow" of a mask.
分类信息
The burnished-buff tanager was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the 12th edition of his Systema Naturae under the binomial name Tanagra cayana. The specific epithet is the Latin form of the type locality, Cayenne in French Guiana. The burnished-buff tanager was formerly placed in the genus Tangara. It was moved to the genus Stilpnia that was introduced in 2016.<p>Seven subspecies are recognised:

分布与栖息地
It is found in the northern Guianas, most of Venezuela and east-central Colombia; also near the Amazon River outlet in Brazil, as well as most of the east of that country, Paraguay and northeast Argentina. It also occurs very locally in Bolivia and Peru. It can be seen in virtually any semi-open habitat with trees, including human-altered habitats such as gardens, plantations and parks.

Russet-winged Schiffornis
Schiffornis stenorhyncha
A chunky, dark brown bird of the forest understory. Occurs in the lowlands from Panama to Venezuela and Colombia. Uniform color, but slightly warmer rufous on wings and crown. Fairly large hooked bill is reminiscent of a vireo. Skulky and difficult to see; most often detected by voice. Listen for three-parted whistled song with one long note followed by two shorter notes.
Saddle-billed Stork
Ephippiorhynchus senegalensis
A tall, lanky, black-and-white stork with a unique red, yellow, and black bill. The male has dark-brown eyes, and the female has yellow eyes. In flight, the bird’s massive size, and the dark bands in the center of the white wings are diagnostic. Scarce but conspicuous; mostly resident but can be partially nomadic in parts of the range. Found singly or in pairs at rivers and large undisturbed wetlands, foraging for favorites like catfish, but it will also take frogs, birds, and insects.
Pied Honeyeater
Certhionyx variegatus
Medium-sized honeyeater with long decurved bill, nomadic across arid and semi-arid inland Australia. Male black with white belly, wing patches, and tail panels; distinctive patch of blue skin beneath eye. Female and juvenile plain brown, with subtly patterned wings and faint speckles on chest. This species wanders in search of flowering shrubs and can be absent one year, common in large flocks the next. Much larger than Black Honeyeater (which has completely black upperparts). Calls include a slowly whistled phrase of several notes.
