Rufous-sided Crake
Laterallus melanophaius
Often common, but usually hard to see. Best detected by voice, a very long explosive trill. The plumage is olive-brown above with rufous face and sides, and striking black-and-white bars on the flank and vent. Similar to Red-and-white Crake, which lacks the dark cap. Found in damp grasslands, extensive wetlands, and sometimes rank pastures.
Identification
The rufous-sided crake is 14 to 18 cm (5.5 to 7.1 in) long and weighs about 50 to 60 g (1.8 to 2.1 oz). The sexes are alike. Both subspecies' bills have a gray maxilla with a pea green cutting edge and a pale pea green mandible with a white tip. Their legs and feet are light gray brown to olive brown. The nominate subspecies has dark olive brown upperparts with a gray tinge around the eye. The face and sides of the breast are rufous to cinnamon rufous. The throat and center of the breast are white, the flanks and belly barred white and blackish brown, and the undertail coverts are dark cinnamon rufous. Subspecies L. m. oenops is similar to the nominate, but has paler upperparts and is rufous on the forecrown and around the eye.
Taxonomy
The rufous-sided crake has two subspecies, the nominate L. m. melanophaius and L. m. oenops. What is now the white-throated crake (L. albigularis) was for a time treated as a third subspecies.

Range and habitat
The nominate subspecies of rufous-sided crake has much the larger range of the two. It is found from coastal Venezuela east through the Guianas and separately from central and eastern Brazil south through eastern Bolivia, Paraguay, and Uruguay into northern Argentina. Subspecies L. m. oenops is found from southern Colombia south through eastern Ecuador into eastern Peru and east into western Brazil. The species primarily inhabits freshwater marshes and similar landscapes such as flooded pastures and the edges of ponds and oxbow lakes .

White-breasted Fruit-Dove
Ptilinopus rivoli
Male unmistakable, mostly green with a conspicuous white or yellowish chest band, a maroon belly patch, and a red forehead. Female uniform bright green with a yellow line between bill and eye. Bill pale yellow in both sexes. Juvenile greener, with yellow edges to feathers on wings and underparts. Found singly or in pairs in forested lowlands and hills. Yellow bill and facial line in female distinguishes female from female Superb, Black-naped, and other fruit-doves. The species gives a deep “hooO” call note, singly or in a quickly accelerating series that falls off at the end.
Pied Falconet
Microhierax melanoleucos
Ridiculously adorable panda-faced raptor, usually found in extended family groups ranging in size from 4 to 20. Perches on exposed snags, sallying forth to catch prey; capable of taking passerines only slightly smaller than it is. Black above and white below, with a white face and a thick black stripe extending down behind the eye. Flight is fluttery but fast; black barring on the wings and tail is only visible in flight, as is a thick black streak on the armpit, reminiscent of Black-bellied Plover.
North Moluccan Cicadabird
Edolisoma grayi
Small cuckooshrike with a restricted range in the North Moluccan islands. Males are mainly gray with black on the face, wing, and tail. Distinctive female has brown upperparts, with a gray cap and buff fringing on the wing, and buff underparts with fine barring. Found in forest and forest edge habitats at low and middle elevations. Forages singly, in pairs, or in small groups, mainly in the canopy. Vocalizations include a long, cicada-like buzzing note.
