Colombian Crake
Mustelirallus colombianus
A shy and poorly known bird of marshes and wet, grassy areas. Gray with a brown back, buffy lower underparts, a yellow bill with an orange base, and red legs. Very similar to Paint-billed Crake, but lacks barring on the lower underparts; this feature is usually very hard to see in the dense vegetation the bird typically inhabits. Almost never encountered in the field, in part due to the fact that next to nothing is known about its voice.
识别特征
The Colombian crake is 18 to 20 cm (7.1 to 7.9 in) long. The sexes are alike. The nominate subspecies has a brown crown, nape, and upperparts including the tail. Its throat is white and its face, throat, and breast are gray. Its flanks, belly, and vent are cinnamon. M. c. ripleyi is similar but significantly darker.
分类信息
The Colombian crake's taxonomy has not been settled. The North American Classification Committee of AOS (NACC), the International Ornithological Committee (IOC), and BirdLife International's Handbook of the Birds of the World (HBW) place it in genus Neocrex. However, in 2015 the South American Classification Committee of the American Ornithological Society (AOS) and the Clements taxonomy moved it and the paint-billed crake (M. erythrops) to genus Mustelirallus.<p>This article uses the IOC/NACC/HBW genus. The IOC, HBW, and Clements agree that the paint-billed crake has two subspecies, the nominate M. c. colombianus and M. c. ripleyi.

分布与栖息地
The nominate subspecies of Colombian crake is found from northern Colombia south into northwestern Ecuador. M. c. ripleyi is found from central Panama into northwestern Colombia's Chocó Department. There are few records of the species and the exact boundaries of the two subspecies' ranges are not known. The species inhabits wet to moist landscapes such as marshes, swamps, savanna, and the brushy edges of forest; not all of these have water bodies. In elevation it ranges from sea level to 2,100 m (6,900 ft).

行为
The Colombian crake is considered to be sedentary.<p>Nothing is known about the Colombian crake's feeding habits or diet. They are assumed to be similar to those of its closest relative, the paint-billed crake. That species forages in soil, leaf litter, and standing water, and at dawn and dusk has been noted feeding in open areas next to dense vegetation. It is known to eat invertebrates including Diplopoda and Coleoptera and also seeds.<p>The Colombian crake's breeding season is not fully defined but appears to include at least December to February. Nothing else is known about its breeding biology.<p>As of late 2022 xeno-canto had only one recording of a Colombian crake vocalization and the Cornell Lab of Ornithology's Macaulay Library had none. That recording is of an immature bird being held by a researcher and is judged to be a distress call.

Sirkeer Malkoha
Taccocua leschenaultii
Gray-brown cuckoo with a uniquely hooked red bill. Teardrop-shaped dark patch around each eye gives it a distinctly fashionable, elegant appearance. Forages on or close to the ground in the dense undergrowth of dry forests and scrubby areas. Scurries or flaps laboriously away when disturbed.
Olivaceous Flycatcher
Fraseria olivascens
A canopy flycatcher, often found high above the ground in areas with continuous forest, away from the forest edge. True to its name, this flycatcher is mostly olive-brown with a pale throat, a pale vent, and dark grayish legs. Distinguished from other African flycatchers by its preference for the canopy, its voice, and its overall indistinct coloration and patterning. Call is a high-pitched rising “tseee!” and the song is a complex jumble of clear whistles and buzzy notes.
Rufous-capped Motmot
Baryphthengus ruficapillus
Large odd-looking bird with a long tail often swung from side to side or even held cocked when agitated. Usually sits quietly in the midstory and is easy to miss. The body is blue and green, with a black mask, and an orange cap and belly. Normally vocalizes at dawn and dusk an owl-like “hoo-oo-oo-oo-oo.” Nests in burrows.
