Opal-rumped Tanager
Tangara velia
Common tanager, found in a variety of forest habitats. Usually seen from below, in which case it is best identified by uniform dark underparts with rufous lower belly and undertail coverts, and active behavior. The shining white rump can be seen from most angles on perched birds, even when high overhead. Found in tall rainforest, shorter-stature forests on sandy soils, and in disturbed areas. Groups move rapidly through treetops, usually with other species of small tanagers, feeding on fruit. Calls are indistinct chips, often given in rapid series in flight.

In 1743 the English naturalist George Edwards included an illustration and a description of the opal-rumped tanager in his A Natural History of Uncommon Birds. He used the English name "Red-belly'd Blue-bird" ". Edwards based his hand-coloured etching on a specimen owned by the Duke of Richmond that had been collected in Suriname. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the opal-rumped tanager with the wagtails in the genus Motacilla. Linnaeus included a brief description, coined the binomial name Motacilla velia and cited Edwards' work. Linnaeus provided no explanation for the specific epithet; it is perhaps a misprint for the Ancient Greek elea, a small bird mentioned by Aristotle. The bay-headed tanager is now placed in the genus Tangara that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The type locality is Suriname.<p>Four subspecies are recognised:

Palila
Loxioides bailleui
A rare Hawaiian honeycreeper of high elevation dry forests on the western slope of Mauna Kea volcano on Hawaii Island. Occurs only above 6,500 feet. Males and females are similarly patterned but males are more brightly colored. Quiet and generally shy, but males may sing from an exposed perch. Sometimes found in pairs or small groups. Feeds primarily on green seed pods of the mamane tree. Call is a soft “pah-lee-lah.”
African Pipit
Anthus cinnamomeus
The default pipit across much of Africa. Brown above and pale below, with a streaked back, well-marked face, and white outer tail feathers. There is considerable geographic variation, from pale and sandy to rich brown and rufous. Found in a variety of open and usually grassy habitats, both near water and in dry areas. Call is a sneezing “tzsht”. Song comprises consecutive series of rattles, given in flight. Very similar to other pipits; some of the key features to look for include the yellow base of the bill, streaked back, and white outer tail feathers.
Charlotte's Bulbul
Iole charlottae
Dull brown bulbul with a long bill and pale eyes. Endemic to Borneo, where it inhabits lowland forests and forest edges. Fairly adaptable, often occurring in degraded and regenerating wooded habitats. May be easily confused with other plain bulbuls; note this species’ pale eyes, unmarked yellowish-suffused underparts, and clean white throat. Not as social as some other bulbuls, typically moving through the middle and upper levels of forest individually or in pairs. Gives a somewhat hoarse “jeet!” and a nasal “jee-wit!”, and a repetitive series: “wee-jy-jy-jy!”
