Ecuadorian Piedtail
Phlogophilus hemileucurus
Fairly small hummingbird with a limited range in the foothills on the east slope of the Andes from southern Colombia to northern Peru. The broad white collar and extensive white in the tail are the most obvious field marks, otherwise it is green above and white below with a straight bill. Occasionally visits feeders, but is more likely to be found in the understory of forests in the foothills from around 900 to 1,300 m. Compare with female Booted Racket-tail and Rufous-vented Whitetip.

分布与栖息地
The Ecuadorian piedtail is found in the eastern foothills of the Andes from Colombia's Putumayo and Cauca departments south through eastern Ecuador into northeastern Peru's departments of San Martín and Loreto. It inhabits primary forest edges and secondary forest at elevations between 500 and 1,200 m (1,600 and 3,900 ft).

行为
The Ecuadorian piedtail is mostly sedentary but local altitudinal movements are believed to be likely.<p>The Ecuadorian piedtail typically forages between 2 and 4 m (7 and 13 ft) above the ground. It perches to take nectar from flowers and to glean small insects from foliage.<p>The Ecuadorian piedtail's breeding season spans from December to April. The typical nest is a cup of fine rootlets and fern leaf placed 2 to 3 m (7 to 10 ft) above the ground. It is sited in vines or under overhanging thickets. The clutch size is two eggs.<p>The Ecuadorian piedtail's song is "a series of typically three high-pitched buzzy notes...followed by several twittering notes 'tzeeeee...tzeee.tzew..tititititi', continuously repeated." Its calls include "a descending series of 3–4 high-pitched 'see' notes..., a repeated 'tsik' note and high-pitched twittering."

Red-knobbed Coot
Fulica cristata
Mostly sooty gray waterbird with a white beak and frontal shield. Breeding adults have two small reddish horns, but at other times difficult to separate from Eurasian Coot. Feathering on the side of the upper mandible is rounded rather than pointed. The bill is blueish rather than pinkish and in flight it lacks the white edge on the secondaries seen on Eurasian Coot. Found in open freshwater including lakes, rivers, reservoirs, and lagoons.
White-browed Tit
Poecile superciliosus
A distinctive tit of alpine and subalpine scrub and thickets. Combination of fine white eyebrow, black crown and throat, and rusty-washed face are unique. Usually seen darting about in pairs between cover. Gives a high, thin whispery pair of notes as it darts about in stunted alpine shrubs, rhododendrons, and grasses.
White-capped Tanager
Sericossypha albocristata
Large, boisterous, striking tanager unlikely to be mistaken. Mostly dark blackish, but look for satin-red throat and iridescent steely-bluish wings. Most distinctive is the namesake white cap that shines like sunlit snow. Sexes similar; females and immatures have slightly duller throat. Never common; found in small flocks that move quickly through the canopy of the subtropical and temperate zones in the Andes, sometimes perching conspicuously. Behavior and voice recall a jay and they sound quite similar especially at a distance. Sometimes travels with flocks of Turquoise Jays.
