Scarlet-breasted Fruit-Dove

Ptilinopus bernsteinii

A large, long-tailed green fruit-dove with a yellow-orange lower belly, a pale gray head, and a conspicuous red breast patch in males that is lacking in females. Usually encountered singly or in pairs within the canopy and understory of forest and wooded areas in both lowlands and hills, typically being more abundant in the foothills. Longer-tailed than other local fruit-doves; scarlet breast patch easily identifies males, and both sexes can be identified by their vibrant yellow-orange belly. Call is a staccato two-noted “koo-wooh.”

Resident species

行为

It is presumably a frugivorous species. It is normally quiet, and has been described to emit deep, soft oohoo calls. It also emits odd growling calls. It usually quietly forages alone or in pairs, in forest canopies.

保护状况

Since 1988, the scarlet-breasted fruit dove has been rated as a species of least concern on the IUCN Red List of Endangered Species. This is because although it has a restricted range, the range size is more than 20,000 km2 (7,700 mi2) with a stable population trend. In addition, although its population numbers have not been determined, it is thought to be above 10,000, which does not meet the criterion to warrant a vulnerable rating. The species is described as "uncommon to moderately common", and there is no evidence of major threat to their population.

Rufous-backed Treehunter

Rufous-backed Treehunter

Thripadectes scrutator

Rare and very shy bird of high-elevation cloud forest along the east slope of the Andes. Boldly streaked with black and buff. Plumage is very similar to that of the more common Striped Treehunter, but it is larger and the markings are much more contrasting. Due to the furtive nature of these birds, voice is usually the easiest way to separate them. Rufous-backed Treehunter gives a harsh, rattling trill as well as abrupt “chak” notes. Inhabits dense tangles of bamboo and usually very hard to see.

Knobbed Hornbill

Knobbed Hornbill

Rhyticeros cassidix

A huge black hornbill with a prominent knob on the bill, conspicuous red “gills” on the sides of the beak, a turquoise-blue throat pouch, and a white tail. Males have a red casque and rufous neck, females a yellow knob and black neck. Juveniles resemble male, but with an entirely yellow casqueless bill. Found in pairs or groups in canopy of forested and wooded areas of lowlands and hills. Larger and more colorful than Sulawesi Hornbill. Gives powerful, short “krok” notes and a more drawn-out “oooo-aa-ooo-aaa.”

Swainson's Sparrow

Swainson's Sparrow

Passer swainsonii

A drab sparrow of northeastern Africa. The head and underparts are gray, the wing and back are brown, and the rump is rufous. Generally common within its range in all habitats except closed-canopy forest. Fond of human habitation. Very similar to Northern Gray-headed Sparrow, but there is little overlap in range, and Swainson’s has darker underparts. Also very similar to Parrot-billed Sparrow, but slightly smaller and slimmer-billed, with paler underparts. The call is a ringing “churp.”
