Rufous-tailed Hawk

Buteo ventralis

Scarce and often rather local hawk of temperate rainforest and edge, adjacent open and semiopen areas. Looks similar to the Red-tailed Hawk of North America. Hunts from perches, less often in flight. Light morph has dark leading edge to underwing; adult has diagnostic rusty tail with narrow dark bars. Rare dark morph has dark body plumage, adult tail washed grayish; immature has broader, blunter wings than very similar dark-morph immature of Variable Hawk.

分布与栖息地

The rufous-tailed hawk has been spotted living in a number of different habitat types, including evergreen beech forest, mature forest and new growth forest that have been burned over, and finally in open country. The best theory for their ideal habitat was developed by Figueroa et al. (2000), Trejo et al. (2006), and Rivas et al. (2009), who all suggested that rufous-tailed hawks' ideal habitat is somewhere with high trees near open areas that are good for hunting for prey. So far, there have been no reports of the rufous-tailed hawk living in human areas like cities or abandoned buildings.

Seaside Cinclodes

Seaside Cinclodes

Cinclodes nigrofumosus

Restricted to the rocky coastline of northern and central Chile, where it is rarely seen far from crashing waves; also ranges to adjacent sandy beaches at river mouths. Usually seen as singles or pairs, foraging in the intertidal zone, or singing with wings raised and fluttered from seaside rocks. Largest cinclodes in Chile and identified by very narrow whitish eyebrow, bold white breast streaking, and rather stout bill, which it uses to smash open small crabs. Other cinclodes occur alongside Seaside Cinclodes mainly in winter.

Rufous Chatterer

Rufous Chatterer

Argya rubiginosa

An unusual slim babbler with a long tail. Brown on the upperparts and rufous on the underparts, with a pale eye and bill and a finely streaked crown. Found in woodland and savanna in areas with thick undergrowth, almost always in small groups. Somewhat similar to other babblers, especially Scaly Chatterer, but has much more rufous underparts. The vocalizations include a variety of dry notes, scolds, and mews, usually given in chorus by a whole group. 

Orange-crowned Euphonia

Orange-crowned Euphonia

Euphonia saturata

Small finchlike bird, compact and short tailed with a stout bill. Male has notably orange-tinged underparts and dark upperparts with a purplish sheen. The orange-yellow crown is extensive (not restricted to the forehead like many other euphonias). Also note the underside of the tail, which is entirely dark. Females are plain yellowish-olive overall and difficult to separate from other euphonias, especially Thick-billed, but usually seen in pairs or small groups with males. Frequents woodlands, edges, and clearings in lowlands and foothills, often in fairly dry regions. Can be found in mixed-feeding flocks with other species such as warblers and tanagers.
