Speckled Pigeon
Columba guinea
Big, dark pigeon with white spots across the shoulder and a big red patch of bare skin around the eye. In flight, shows a gray tail band and rump. Found in many different open habitats, and nests in towns and cities and on cliffs. Only absent from thick forest. Common vocalizations are a “rrrour” call and an accelerating series of hoots. Somewhat similar to Rameron Pigeon, but largely absent from forest, and shows much larger wing spots and red rather than yellow bare facial skin.
识别特征
This is a large pigeon at 41 cm in length. Its back and wings are rufous, the latter heavily speckled with white spots. The rest of the upperparts and underparts are blue-grey, and the head is grey with red patches around the eye. The neck is brownish, streaked with white, and the legs are red. Sexes are similar, but immatures are browner than adults and lack the red eye patches. The call is a loud doo-doo-doo.
分类信息
In 1747 the English naturalist George Edwards included a description and an illustration of the speckled pigeon in the second volume of his A Natural History of Uncommon Birds. His hand-coloured etching was made from two live birds at the home of the Duke of Richmond in London. Edwards was told that the pigeons had been brought from the inland region of Guinea in West Africa. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the speckled pigeon with all the other pigeons in the genus Columba. Linnaeus included a brief description, coined the binomial name Columba guinea and cited Edwards' work.<p>There are two recognised subspecies:

行为
The speckled pigeon is frequently seen around human habitation and cultivation. Most of its food is vegetable, and it gathers in large numbers where grain or groundnuts are available. This species builds a large stick nest on protected rocky outcrops and in urban areas often atop covered pergola pillars and on flat roofs under deep eaves and lays two white eggs. Its flight is quick, with regular beats and an occasional sharp flick of the wings that are characteristic of pigeons in general.

其他鸟类
Cinnamon-breasted Tody-Tyrant
Hemitriccus cinnamomeipectus
A small flycatcher found only on several outlying ridges along the eastern Andes in northern Peru and southern Ecuador. It has a cinnamon breast and throat, a yellowish belly, and buffy “spectacles” that can be inconspicuous on some individuals. Inhabits lower to middle levels of stunted cloud forest, where it can sometimes be hard to spot as it flits from one perch to another in the gloom. Calls include a short, downslurred trill and a series of three to seven sharp squeaks.
Olive Flycatcher
Mitrephanes olivaceus
A perky, pewee-like flycatcher found in humid forest along the east slope of the Andes. The combination of its small size, buffy-olive plumage, and obvious crest is unique within its range. Often perches in a conspicuous location, looking around excitedly for insects to chase, and readily joins mixed-species flocks. Typical vocalization is a series of soft tick notes which is often followed by a high pitched “seep.”
White-rumped Hawk
Parabuteo leucorrhous
Small raptor of montane forest in the Andes from Venezuela to Argentina, with a disjunct population in southeastern South America. Adults are black with a piercing yellow eye. In flight, look for the paddle shaped wings and contrasting white underwing coverts. The tail has contrasting black and white bands. Juveniles are buffy below with messy dark markings; note the white eyebrow and overall compact shape. Singles or pairs are uncommon over forest or adjacent clearings. Typically seen soaring or occasionally perched in the canopy.
