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.”

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.

Goliath Heron
Ardea goliath
This enormous heron stands 1.5 meters tall and has a robust, dagger-like bill. The immature has rustier upperwings than the adult. Its flight is ponderous and labored. Goliath Heron inhabits large rivers, marshes, estuaries, and mangroves, hunting for large fish and other animals, stabbing them with an open bill. It has a distinct, barking “kowoork” call that can be heard from up to 2 km away. Purple Heron has similar plumage, but Goliath Heron is twice the size, has a much larger bill, and has a rufous (not blackish) top of the head.
Fiery-throated Fruiteater
Pipreola chlorolepidota
Small, scarce fruiteater found in cloud forest in the eastern foothills of the Andes. Both sexes are mostly green. Male has a ruby-red throat and a yellowish belly. Female has a yellow chin and yellow scaling on the belly. Female is similar to female to Scarlet-breasted Fruiteater but smaller and with a black (not orange) bill. Feeds on berries in middle to upper levels in the forest, and often found in pairs.
Moustached Warbler
Acrocephalus melanopogon
Resembles Sedge Warbler, but larger with a thick and well-marked white eyebrow and throat; contrasting dark cap; rufous rump, nape, and sides; short wings; and dark legs (pale in Sedge). Found in dense reed beds, often with bulrush stands. Makes muffled "treck" calls recalling a stonechat. Scratchy, repetitive song is given from the upper half of a plant stalk; does not sing in flight.
