Eared Dove
Zenaida auriculata
South America’s most widespread and abundant dove, found from sea level up to 4,000 m. Appearance much like Mourning Dove of North America: pale grayish-brown overall with iridescent patch on neck, black spots on wing and neck, and reddish legs. Larger than ground-doves; more slender than Leptotila doves and with black wing spots. Found in open and disturbed habitats including agricultural fields, towns and cities, and shrubby areas. Often gathers in flocks.
识别特征
The eared dove is 24 cm (9.4 in) long with a long, wedge-shaped tail, and weighs normally about 112 g (4.0 oz). Adult males have mainly olive-brown upperpart plumage, with black spots on the wings. The head has a grey crown, black line behind the eye, and the blue-black on the lower ear coverts. These black markings give the species its English and specific names. The underparts are vinous, and the tail is tipped with cinnamon. The bill is black and the legs dark red.<p>The female is duller than the male, and immature birds are greyish-brown, very dull, with pale barring. The species' call is a deep soft oo-ah-oo.

行为
The eared dove is common to abundant in savannahs and other open areas, including cultivation, and it readily adapts to human habitation, being seen on wires and telephone posts near towns in Trinidad and Venezuela, in almost all public spaces of large urban areas such as Bogotá, Colombia, and feeding near beach resorts in Tobago.<p>Eared doves feed mainly on seed and grain taken from the ground. They can be agricultural pests. When in season, agricultural plants such as wheat, rice, sorghum, maize and soybeans may comprise the entirety of the diet. Echinochloa colona, a common savannah grass, and Croton jacobinensis are important seed food for these doves. Their diet may also be augmented by animal foods, such as caterpillars, insect pupae, aphids and snails. This is a gregarious bird when not feeding, and forms flocks especially at migration time or at communal roosts.<p>Its flight is high, fast, and direct, with the regular beats and an occasional sharp flick of the wings, which are characteristic of pigeons in general. It also has a breeding display with a steep climb and semicircular glide down to its original perch. It builds a small stick nest several meters up in a tree and lays two white eggs. These hatch in 12–14 days with another 9 days to fledging. No fixed breeding season is seen in most of their range, and provided with plentiful food and habitat, birds breed almost continuously.

Golden Whistler
Pachycephala pectoralis
Compact songbird with short bill. Males in much of range are olive above, yellow below, with white throat set in black head; males and females on Norfolk Island are olive-brown with yellowish underparts (brightest on undertail). Females vary across range, with eastern birds having some amount of yellow on the underparts and western birds (formerly treated as full species, “Western Whistler”) being gray-brown above and pale below, lacking yellow. Olive Whistler much browner below, with well-defined whitish bib. Inhabits a great variety of habitats. Bright, whistled song varies, but often has a whip-like ending.
Collared Inca
Coeligena torquata
This large, flashy hummingbird is a common resident throughout much of the Andes, where it inhabits lush cloud forest and frequently visits feeders. Note the white breast patch and long, straight bill. The white tail markings really stand out when it flares its tail, which it often does when interacting with other hummers around feeders. Male is darker than female, sometimes almost black, which makes his colorful crown patch more evident. Birds found south of central Peru and north of the Colombia-Venezuela border region are now considered to be separate species, Gould’s Inca and Green Inca respectively.
Flores Shortwing
Brachypteryx floris
An elusive, small songster of dense montane forest undergrowth on Flores. Male has dull blue-gray upperparts with paler gray chest and sides. Female has warm brown upperparts with more rufous on the wings, rump, and pale rufous under the tail. Both sexes have white throat and mid-belly, and a thin, white eyebrow. Female similar to Lesser Shortwing, but Flores has a gray chest. Song is a jumble of whistles and scratchy notes. Also gives a loud “tak!” call.
