Bare-cheeked Trogon
Apaloderma aequatoriale
A trogon of lowland rainforests, almost always found in the forest interior, away from forest edges. Males and females have distinctive bare yellow facial skin below their eyes and between their eyes and bill. Both sexes have green backs and uppertails, red chests and vents, and finely barred wings. The species often calls motionless in the subcanopy, giving a series of 6-10 sad, descending coo notes, repeating these series 2-3 times per minute. Similar to the larger Narina Trogon, but Bare-cheeked Trogon is told apart by its song, its closed-canopy forest habitat, and the purely green tones on its head, back, and uppertail.
Identification
The bare-cheeked trogon physically resembles the narina trogon, but it has bright yellow facial skin while narina trogons have green facial skin. They also differ from narina trogons in smaller size and shorter tail. Bare-cheeked trogons are sexually dismorphic. The male's back, head and upper breast is green blueish; and its lower breast is pinkish red. Its wings are pale grey and finely barred; and it has a yellow bare facial patch. The female shares the same wing coloration and also has that distinct yellow facial patch, however her whole breast is pinkish red and only her back and the back of her head are green blueish. Both sexes have a white undertail and a yellow bill and measure 28-31 cm.<p>They have heterodactyl feet which is a distinctive feature only Trogons share.
Taxonomy
Bare-cheeked trogons are part of the order Trogoniformes which only includes one family: Trogonidae. This family includes a variety of species who live in tropical and subtropical forests throughout the Americas, Africa, Asia and Pacific islands . The Bare-cheeked trogon is one of three African species belonging to the Apaloderma genus. The other two species are bar-tailed trogon and narina trogon. Based on molecular data, narina trogons and bare-cheeked trogons are sister-taxa. The bare-cheeked trogon does not have any subspecies as they are monotypic.

Range and habitat
Bare-cheeked trogons are found year-round across central west Africa and do not typically migrate. It is found in Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon, and Nigeria.<p>The bare-cheeked trogon lives in interior regions of lowland rainforests. They can be found in closed-canopy swamp-forest, low-lying liana-rich flood forest and logged forest with intact canopy. They spend most of their time in the subcanopy and rely on tree cavities to nest.

Behavior
Bare-cheeked trogons can be easily differentiated from narina trogon by their songs. They have a distinct song described as a series of 6-8 “chuu”s repeated every 15–20 seconds. When adults arrive at the nest with food, they emit low grunting calls. It has been reported that bare-cheeped trogons engage in singing aggregations. This calling assemblage involves a group of 3 to 10 adult males, with occasional instances of up to 20, continuously vocalizing as they pursue each other from one perching spot to another. Male narina trogons may also join this aggregation. These calling assemblages happen during brood period so they may be related to reproduction but it still remains uncertain as they do not lead to copulation. This behavior is common to several trogon species.<p>Just like their sister-taxa, narina trogons, bare-cheeked trogons are insectivores and feed on large green caterpillars, beetles, moths, mantises and bush-crickets. They also feed on grass and moss. They hunt similarly to drongos and can sometimes chase their prey to the ground. Indeed, their sister-taxa narina are sallying insectivores and hunt by launching from a stationary position onto stationary or moving prey, which might be a shared behavior, however little is known about their hunting practices.<p>There is no fixed breeding season, it varies from region to region. They are monogamous and territorial. The male will fight for the possession of the nest which are formed in cavities 2–8 m up in rotting trees. Two eggs will be laid and will take 16 days to hatch. Once hatched, the young will be fed by both parents for another 16 days, hence both sexes participate in parental care.

Black-faced Ibis
Theristicus melanopis
Large, boldly patterned, and often noisy ibis. Common and conspicuous in cooler and wetter regions of southern Chile and Argentina; uncommon and more local in northern areas. No similar species in range. Favors open country, especially wet grasslands, but also ranges to open forest and beaches. Nests colonially in trees and on cliffs, including in towns and even cities. Soars easily on broad wings, sometimes high with kettles of vultures. Loud trumpeting cries carry long distances.
Munchique Wood-Wren
Henicorhina negreti
A small, stub-tailed wren endemic to Colombia’s western Andes. It has a long, white eyebrow and a streaky face. Very similar to Gray-breasted Wood-Wren, but has very faint barring on the belly. This is very hard to see in the field, and usually voice is the best way to separate them. Munchique Wood-Wren’s song is slightly lower in pitch and the notes are flatter and less squeaky. Inhabits cloud forest understory, usually at higher elevations than Gray-breasted, but with some overlap.
Black-fronted Bulbul
Pycnonotus nigricans
A typical open-country African bulbul with a dark head and a conspicuous and diagnostic fleshy orange-red eye-ring. Pairs and small groups forage in riverine thickets in the Karoo and in arid thorny woodland and scrub, eating a variety of fruit and invertebrates. The species has a typical bubbly musical bulbul song, slower than that of the similar-sounding Common Bulbul. The juvenile Black-fronted Bulbul may be confused with the similar looking Common Bulbul, but it is often accompanied by adults with their diagnostic eye-rings.
