Buru Mountain-Pigeon
Gymnophaps mada
A large pigeon confined to Buru. Shows a pale gray crown and nape, slate-gray upperparts, and a cream throat and breast becoming salmon-pink on the belly. Also note the red eye-ring and the red base to the pale bill. Juveniles are browner above, duskier below. Singles or pairs inhabit mainly foothill and montane forest, but occasionally lowlands. Extensive pale areas on both throat and breast, plus the pale gray crown and nape, separate it from Metallic Pigeon. Calls not yet confirmed, but a deep “wuooo” has been reported.
Identification
The Buru mountain pigeon is a medium-sized pigeon with a slender build, and long wings and tail, measuring 33–38.5 cm (13.0–15.2 in) long. Adult males have blue-grey crowns, napes, and hindnecks, with darker mantles. The rest of the upperparts are slightly glossy dark slate-grey. The flight feathers on the wings and tail are greenish-black, while the primaries and the ends of the flight feathers on the tail have narrow pale fringes. The face, throat, and upper breast are white to pale buff-pink, while the belly is buff-pink. The feathers on the upper leg are pale buff. The iris is grey, pale brown or yellow, with a red or orange outer ring. The beak is ashy-yellow with a red base, and the legs are purplish to brownish-red. The species shows slight sexual dimorphism, with females being smaller on average and having more wine on the breast, along with dark blackish-red bills and ceres. Juveniles have browner upperparts, dusky mottling on the throat and breast, and more ochre on the belly. They also have a white-tipped grey bill, a dull red cere, and dull red legs.<p>The Buru mountain pigeon's vocalisations are unknown, but it is likely silent most of the time like other Gymnophaps pigeons.
Taxonomy
The Buru mountain pigeon was described as Columba mada by the German ornithologist Ernst Hartert in 1899 on the basis of specimens from Mount Mada on Buru, Indonesia. In 1900, he stated that if the genus Gymnophaps (which then only contained the Papuan mountain pigeon) was to be maintained, it would have to include the Buru mountain pigeon as well, although he preferred keeping both the Papuan and Buru mountain pigeons in Columba. Later, James L. Peters, in his 1937 Check-list of the Birds of the World, placed both of these species in Gymnophaps.<p>The name of the genus, Gymnophaps, is derived from the Ancient Greek words γυμνος (gumnos), meaning bare, and φαψ (phaps), meaning pigeon. The specific epithet mada is from Mount Mada, the species' type locality (place where the first specimen of the species was found). Buru mountain pigeon is the official common name designated by the International Ornithologists' Union. Other common names for the species include Mada mountain pigeon and long-tailed mountain-pigeon.<p>The Buru mountain pigeon is one of four species in the mountain pigeon genus Gymnophaps, which is found in Melanesia and the Maluku Islands. It forms a superspecies with the other species in the genus. Within its family, the genus Gymnophaps is sister to Lopholaimus, and these two together form a clade sister to Hemiphaga. The Seram mountain pigeon was previously considered to be a subspecies of the Buru mountain pigeon, but was split on the basis of differences in appearance in 2007 by Frank Rheindt and Robert Hutchinson. The Buru mountain pigeon is now treated as having no subspecies.

Range and habitat
The Buru mountain pigeon is endemic to Buru in the Maluku Islands. It mainly inhabits hill and montane forests, and occasionally visits lowland disturbed forests to feed. It has been recorded at elevations of 0–2,060 m (0–6,759 ft), but mainly occurs at 650–1,760 m (2,130–5,770 ft).

Behavior
Buru mountain pigeon usually occurs alone or in pairs, and in small flocks with up to 11 birds from October to December. During other parts of the year, it may also form larger groups. It roosts high in the mountains, and flies to the lowlands in the morning to feed, returning to the roosts in the evening. The species is frugivorous and most likely feeds on fruit in the canopy. It has been observed visiting coastal fruiting trees. The breeding season may be from October to December.

Other Birds
White-throated Barbtail
Premnoplex tatei
Active, small white-spotted dark-brown bird with white throat and spiky tail. Sexes similar. Locally fairly common in Paria region, uncommon in Caripe area. Usually foraging alone or in pairs, family groups, or mixed species flocks in mossy understory of cloud forest, often rich in palms. Easiest to find by song, a series of bubbling notes, especially in the morning when vocally active. No similar species in range. Endemic to the Turimiquire and Paria regions of northeastern Venezuela.
Whitehead's Trogon
Harpactes whiteheadi
Breathtaking, thickset trogon found only in Borneo’s north-central mountains. Male is predominantly bright red, whereas the female is mostly tan-orange; both sexes have a broad silverish “apron”, orangish-brown back, dark face, and blue bill and skin around the eyes. Favors damp, well-shaded sections of montane forest, where individuals and pairs sit quietly at mid-levels. Gives a well-spaced series of squeaky hoots.
Nicaraguan Grackle
Quiscalus nicaraguensis
Long-tailed blackbird, very similar to Great-tailed Grackle but smaller. Male is darker black with less obvious glossiness (but still some, usually greenish); female is very similar to female Great-tailed but paler below. Extremely limited range in the vicinity of Lake Nicaragua and Lake Managua, where small flocks can be found in open grasslands and wetlands.
