Lineated Woodpecker
Dryocopus lineatus
Large ‘woody woodpecker’ of tropical forest in lowlands and foothills. Also ranges into semi-open areas with tall trees, mangroves, and other lightly wooded habitats. The tufted red crest and black face distinguish it from adult Pale-billed Woodpecker, which often occurs in the same areas. Also note that the white ‘braces’ on the back of Lineated are widely spaced, unlike Pale-billed. Laughing call suggests a flicker, and very unlike calls of Pale-billed.
Identification
The lineated woodpecker is 31.5 to 36 cm (12.4 to 14.2 in) long. It resembles the closely related pileated woodpecker (Dryocopus pileatus) of the United States and Canada.<p>Adults are mainly black above, with a red crest and whitish lines from the base of the bill, down the neck and shoulders (though individuals from the south-eastern part of its range commonly lack the line on the shoulders). The underparts are whitish, heavily barred with black. They show white on the wings in flight. Adult males have a red line from the bill to the throat (malar) and a red forehead. In adult females, these plumage features are black. The bill is typically black in both sexes, though pale-billed individuals regularly are seen.<p>The call of this widespread but wary bird is a loud, ringing wic-wic-wic. Both sexes drum.<p>In most of its range, it is most likely confused with the crimson-crested woodpecker (Campephilus melanoleucos), which is similar in plumage and size. In the female of that species, the light face line is far broader, and the white shoulder lines meet on the back lower back (forming a "V"). The male crimson-crested woodpecker is quite different with its almost entirely red head.
Taxonomy
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the lineated woodpecker in his Ornithologie based on a specimen collected in Cayenne, French Guiana. He used the French name Le pic noir hupé de Cayenne and the Latin name Picus niger cayanensis cristatus. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the 12th edition, he added 240 species that had been previously described by Brisson. One of these was the lineated woodpecker. Linnaeus included a terse description, coined the binomial name Picus lineatus, and cited Brisson's work. The specific name lineatus is Latin and means "lined" or "marked with lines". The lineated woodpecker is now one of six species that the International Ornithological Committee (IOC) and the Clements taxonomy place in the genus Dryocopus. The North American Classification Committee of the American Ornithological Society concurs for the lineated and pileated woodpeckers, the only two of the six that occur in Central and North America. However, BirdLife International's Handbook of the Birds of the World (HBW) places the pileated and several others in the genus Hylatomus. Genus Dryocopus was introduced by the German naturalist Friedrich Boie in 1826.<p>The IOC and Clements recognize these five subspecies:<p>However, HBW separates D. l. fuscipennis as the "dusky-winged woodpecker".

Behavior
The habitat of this species is forest borders and other open woodland. It is not generally a mountain bird, though it has occasionally been recorded in the uplands (e.g., in the Serranía de las Quinchas of Colombia) Three white eggs are laid in a nest hole on a dead tree and incubated by both sexes. The young are fed by regurgitation.<p>Lineated woodpeckers chip out holes, often quite large, while searching out insects in trees. They mainly eat insects, especially ants and their larvae, beetles and their larvae, termites, orthopterans, caterpillars with some seeds, such as from Heliconia and Clusia rosea, and fruits, berries, and nuts.<p>Lineated woodpeckers breed March–April in Panama, April–May in Belize, and February–April in Trinidad and Suriname. Nest cavities are excavated in dead trees at variable heights, from 2 to 27 m (6.6–88.6 ft) above the ground. Both sexes excavate the nests, which are about 45 cm (18 in) deep, 13 cm × 18 cm (5.1 in × 7.1 in) wide, and have an entrance about 9 cm (3.5 in) in diameter. Clutch size ranges from 2–4 eggs (2–3 in Trinidad). Males and females take 2- to 3-hour shifts incubating during the day, but only males incubate at night. Chicks are fed about once an hour by both parents through regurgitation; the female does most of the feeding while the male guards the nest. Incubation and fledging periods not documented.

Maroon-backed Whistler
Coracornis raveni
A sparrow-sized, thick-billed songbird from the mountains of Sulawesi. Male is distinctive, almost entirely dark sooty gray except for the maroon back. Female and juvenile are nondescript, entirely dark rusty-brown above and dull olive underneath, but paler on the undertail. A shy inhabitant of montane forest, where singles and pairs stay low in the understory. Female is dark on the breast, unlike Sulphur-bellied Whistler, and lacks yellow flanks, unlike Hylocitrea. Vocalizations are characteristic of whistlers, often including whipping notes: “chiyoo-WHIT” and “chi-WHIT.” Also gives a subdued “brrrr-chit.”
Northern Gray-headed Sparrow
Passer griseus
Plain sparrow with a gray head and underparts, and brown back, wings, and tail. Found in a variety of open habitats, mostly in association with human settlements. The call is a simple “cheep” that is frequently repeated. Very similar to Southern Gray-headed, Swahili, and Parrot-billed Sparrows. Slightly larger and bigger-billed than Southern Gray-headed Sparrow, with a smaller pale shoulder patch. Paler underparts than Swahili Sparrow. Smaller bill and paler underparts than Parrot-billed Sparrow.
Cape Starling
Lamprotornis nitens
A medium-sized iridescent blue-green glossy starling that lacks dark ear-patches and has greenish flanks and belly, giving it a more uniform appearance than the “blue-eared” starlings. Pairs and small groups occupy high-altitude grassland, Karoo, and savanna, including drier habitats than other glossy starlings. The species feeds on the ground and in trees on fruit and insects; often it scavenges from people. It gives a rolling “turrreaau” flight call and harsh “karrr” alarm notes. Similar “blue-eared” starlings differ from Cape Starling by being smaller and having blue-magenta flanks and belly that give them a less uniform appearance.
