Saffron-crowned Tanager
Tangara xanthocephala
Small tanager found in Andean subtropical zone from Venezuela to Bolivia. Mostly bluish-green with darker wings and streaked back. Head is mostly bright yellow or orange with small black mask, throat, and nape. Buffy undertail coverts and vent only visible at some angles. Sexes alike. A fairly common member of mixed flocks from around 1,200–2,400 m, in cloud forest and edges.
Identification
The saffron-crowned tanager is an average-sized species of tanager, with a length of 12.5–13.5 cm (4.9–5.3 in) and a mass of 15–23.6 g (0.53–0.83 oz). Both sexes look similar. Adults have a blue-green body with blackish streaking on the back. The forecrown, lores, orbital area (region around the eyes), and chin are black, while the rest of the head is yellow, with an orange tinge to the crown. The wings and tail feathers are black, edged blue-green. The center of the belly and the undertail coverts are buff. The iris is dark brown, the bill is black, and the feet are gray. Juveniles are similar to adults but duller and more greenish. They also have yellowish-green instead of yellow on the head and buff-edged underparts.<p>The saffron-crowned tanager may be confused with the golden-eared and flame-faced tanagers. It can be distinguished by the former's black mid-crown and nape, and by the latter's solid black back and opalescent patch on wing coverts.<p>The saffron-crowned tanager's calls include a thin, high-pitched tsit and a high-pitched descending tsew. Its songs may be a series of squeaky, high-pitched notes.
Taxonomy
The saffron-crowned tanager was first described as Callospiza xanthocephala by Johann Tschudi in 1844 based on a specimen from Peru. The generic name Tangara is from the Tupí word tangara, meaning "dancer". The specific name xanthocephala is from the Ancient Greek ξανθος (xanthos), meaning yellow, and κεφαλος (kephalos), meaning -headed. Saffron-crowned tanager is the official common name designated by the International Ornithologists' Union. Other names for the species include saffron crowned tanager.<p>It is one of 27 species in the genus Tangara. Within the genus, it was placed in a species group with the blue-whiskered tanager, green-and-gold tanager, emerald tanager, golden tanager, silver-throated tanager, golden-eared tanager, and flame-faced tanager by Isler and Isler in 1987. This placement is supported by a 2004 study of mitochondrial DNA by Kevin Burns and Kazuya Naoki. Within the species group, the saffron-crowned tanager is sister to a clade formed by blue-whiskered tanager, green-and-gold tanager, emerald tanager, golden tanager, silver-throated tanager, and flame-faced tanager. The following cladogram shows phylogenetic relationships within the species group based on the above study:<p>There are three recognized subspecies of the saffron-crowned tanager, which differ in the color of their crown.

Range and habitat
The saffron-crowned tanager is found in the Andes of Bolivia, Colombia, Ecuador, Peru, and Venezuela, where it inhabits cloud forests, forest edges, and secondary forest. It is also found in shaded plantations and large trees next to clearings and pastures. The species shows a preference for areas with mossy trees and inhabits elevations between 1,000–2,700 m (3,300–8,900 ft).

Behavior
The saffron-crowned tanager is generally found in pairs or small groups of 3–10 individuals, mainly in mixed-species flocks with other species of tanagers and other canopy birds. In Venezuela, it is most often seen with the beryl-spangled tanager, golden tanager, and black-capped tanager.<p>The saffron-crowned tanager is the most frugivorous species in its genus. Fruits consumed include Cecropia, Morus, Miconia, and others in the family Melostomataceae. It also feeds on insects. The species is very active while foraging, with individuals constantly moving around or hopping while foraging. Foraging occurs primarily in the canopy, although fruit is foraged at all heights. Fruit is mainly gleaned while upright, but insects are foraged mainly from mossy branches by inspecting both sides of the branch, and then reaching into clumps of moss or sticking its whole head into moss.<p>The saffron-crowned tanager forms breeding pairs and is thought to be socially monogamous. Individuals in breeding plumage have been reported from March–July. Juveniles have been reported in April in Venezuela, in March, April, and September in Colombia, in February, April, and August in Peru, and in November and December in Bolivia. The only known nest was found in November and was placed at a height of 12 m (39 ft) in moss on the underside of the lowest branch of a tree, containing a clutch of two eggs.

Other Birds
Bougainville White-eye
Zosterops hamlini
Small social songbird, often encountered foraging in upper levels of forest. Mostly olive-green above with a yellow undertail. Belly, chest, and throat gray. Note the smudgy black patch in front of the eye and bright white eye-ring. Found in forest and forest edge from around 900 to 1950 meters of elevation. Similar to Yellow-throated White-eye, but upperparts less yellow and throat gray. Common calls include a loud mellow “peeeu” and high-pitched “peep-peep” foraging calls.
Brown-backed Needletail
Hirundapus giganteus
A very large swift with broad wings pinched at the base, a protruding front, and a bulky rear. Short tail has well-defined spines that can be seen even in fast flight. It has blackish-brown upperparts with a pale-brown saddle, often difficult to make out; the underparts from the throat to the lower breast are dark brown, ending in a well-demarcated deep “V” that contrasts strongly with the white belly, vent, and undertail. When seen well, it shows white lores, a feature absent in other large needletails. It has an extremely fast and powerful flight and hence can suddenly appear from nowhere and disappear quickly.
Floreana Mockingbird
Mimus trifasciatus
A fairly large gray-and-white songbird with a long tail, curved bill, and black blotches on sides of breast. Endemic to Galápagos. Now found only on two tiny islets (Gardner and Campeón) off the coast of Floreana Island, it is the only species of mockingbird in its range. Tourists are not allowed to land on these islets, so the birds are usually seen from a boat while they are perched up on cacti or small trees.
