Pacific Hornero
Furnarius cinnamomeus
Thrush-sized, plump bird of open habitats, especially near water. Particularly fond of disturbed areas, often around human settlements, clearings, and roadsides. Builds an impressive dome-shaped mud nest. Rich rufous above and pale tan below, with a whiter throat and eyebrow. Look for staring pale eye. Most often seen strutting confidently on the ground, and also perches high in a tree or atop a building to sing: listen for a long, loud, descending series of explosive “pee” notes. Mostly restricted to lowlands and foothills in western Ecuador and northwestern Peru, just barely occurring in far southwestern Colombia.
识别特征
The Pacific hornero is 19 to 20 cm (7.5 to 7.9 in) long and weighs about 45 to 63 g (1.6 to 2.2 oz). It is a medium-sized hornero with a long and somewhat decurved bill. The sexes' plumages are alike. Adults have a wide whitish supercilium, a narrow brownish gray stripe through the eye, tawny ear coverts, and a tawny-rufous malar area. Their crown is gray-brown. Their back, rump, and wing and uppertail coverts are bright orange rufous. Their tail is chestnut. Their flight feathers are blackish with a wide rufous band. Their throat is white and the rest of their underparts pale cinnamon-buff. Their iris is yellow to whitish, their maxilla mostly dark, their mandible pale, and their legs and feet pale brownish gray.
分类信息
The Pacific hornero's taxonomy is unsettled. The International Ornithological Committee (IOC), BirdLife International's Handbook of the Birds of the World (HBW), and the Clements taxonomy treat it as a monotypic species. The South American Classification Committee of the American Ornithological Society (SACC) treats it as a subspecies of the pale-legged hornero (F. leucopus). Early authors (e.g. Chapman) had treated them separately. The SACC accepts that cinnamomeus may deserve species rank but declined to make the split due to "insufficient published data".

分布与栖息地
The Pacific hornero is found from far southwestern Colombia's Nariño Department south through western Ecuador and into northwestern Peru as far as Ancash Department. It first appeared in Colombia in 2012 and is possibly expanding its range even further north.<p>The Pacific hornero inhabits a wide variety of semi-open to open landscapes, mostly in the lowlands. These include forest and woodlands along rivers (gallery forest), the edges of secondary forest, agricultural areas, and parks and gardens in towns. It favors areas of middling humidity, usually near water, and shuns very humid and very arid areas. In elevation it mostly occurs below 1,500 m (4,900 ft), though in Ecuador's Loja Province it reaches 2,300 m (7,500 ft) in the subtropic zone.

行为
The Pacific hornero is a year-round resident throughout its range.<p>The Pacific hornero's diet is mostly a variety of arthropods. It also includes other small invertebrates like snails and there are records of the species catching small fish in shallow pools near the end of the dry season. It forages singly or in pairs while walking on the ground, turning over leaves to glean and probe for its prey.<p>The Pacific hornero's breeding season appears to include at least January to April. Though its nest has not been formally described, it is an "oven" of mud with an inner chamber lined with dry plant matter. Both members of a pair construct it, typically on a tree branch but also on horizontal structures like the crossbars of utility poles. The clutch size is two or three eggs. The incubation period, time to fledging, and details of parental care are not known.<p>The Pacific hornero is very vocal. Its song is "an arresting - at times almost raucous-and fast series of loud piercing notes that gradually slows and drops in pitch". Members of a pair sometimes sing in unison. One call is "a loud and clear 'kyeek' ".

Red-eyed Vireo
Vireo olivaceus
Plain olive-green above and whitish below with no wingbars. Red eye of adults is not always easy to see; immatures have brown eyes. Dark stripe through and above eye. Larger and thicker-billed than warblers. Breeds in mature deciduous forest. Often sings nearly nonstop throughout the day; listen for repetitive musical phrases coming from the treetops. Often with flocks of chickadees and warblers during migration. Winters in South America, where it could be confused with the very similar Chivi Vireo, from which it is best distinguished by voice.
Orange-banded Thrush
Geokichla peronii
An unmistakable thrush with a “tiger-striped” face pattern, a white throat, a broad orange chest band, orange flanks, a white belly, and extensive bold white wing markings. Juveniles show rusty wing spots, pale streaking, a black and buff breast band, and black flank spots. Forages singly or in pairs on the ground and in trees, in forests and wooded patches within lowlands and hills. Confined to the eastern Lesser Sundas. Gives a rich, musical song characteristic of thrushes, with sequences of fluty upslurred and downslurred whistled notes comprising repeated phrases mixed with softer, chuckling sounds and thin, high-pitched notes.
White-throated Hawk
Buteo albigula
Locally fairly common summer breeder in temperate rainforests of southern Chile and adjacent Argentina; migrates north in March–April to winter in Andes from Bolivia to Venezuela, returning in September–October. Usually seen in flight over forest and edge, circling high or kiting motionless in the wind; rarely seen perched. Note dark head and clean white throat, diagnostic dark “armpits,” and rather flat-winged gliding with wingtips curled up slightly. Compare with immatures of the larger Variable and Rufous-tailed Hawks.
