Giant Antpitta
Grallaria gigantea
Impressively large antpitta of Andean cloud forest in Ecuador and southern Colombia. Oddly proportioned, with short tail, long legs, and stout bill. Underparts are cinnamon or buff with dense black barring; also note gray crown and brown back. Compared to Undulated Antpitta, it is larger and lacks gray back and white throat. Generally quite rare but regularly visits worm feeders in some locations. Mostly terrestrial but may perch quite high while singing. Song is a long, rising trill that gets steadily louder.
识别特征
G. gigantea is, as its name suggests, a huge antpitta. Length ranges from 24 to 28 centimetres (9.4 to 11.0 in) and weight is up to 300 grams (10.6 oz), which makes it easily the heaviest of all tracheophone suboscine birds – its nearest rival, the chestnut-throated huet-huet, is not known to exceed 185 grams (6.5 oz). Its back, wings, and the stubby tail are dusky olive-brown. The top of the head is pale to medium grey, running down to the neck. The remaining plumage is deep rufous-brown. The throat and breast feathers are black-edged, resulting in a dark barring in these regions. The bill is dark, strong and heavy; the eyes are likewise dark, while the legs and feet are grey.<p>The song consists of low-pitched fast trills, about 14-21 notes per second. These are maintained several seconds, during which they rise in pitch and become louder. Trills are repeated after a pause of a few to about a dozen seconds, which varies irregularly throughout the length of the song. <p>The undulated antpitta (G. squamigera) is a bit smaller, with a pale hue to the malar region and a yellower belly. Its song is hard to distinguish, but rather than simply breaking off after a time, it ends with some additional trills, separated by pauses of increasing length.

Gray-backed Sparrow-Lark
Eremopterix verticalis
A small, compact finch-like sociable lark that is both resident and nomadic, although movements are poorly understood. The sexes differ in plumage: the male has a gray-brown back and wings with a scalloped pattern, and a black head with bold white ear patches that reach the back of the neck; the streaky female is variable depending on geographic range, but always has a dark belly patch and tends to be paler than other female sparrow-larks. Flocks of 20 to 100 birds (often mixed with other sparrow-larks or with Stark’s Lark) can appear in grassy patches in semi-arid shrublands and fallow fields. They shuffle along in bare patches foraging for seeds and insects.

Black-hooded Sierra Finch
Phrygilus atriceps
Attractive small “finch” that is actually a tanager of the high Andes; found in villages, agricultural terraces, scrubby slopes, and bogs. Associates readily with other small seed-eating birds and in some places is tame and acclimated, begging for food at picnic sites. Handsome male is striking and distinctive with a golden back and plain dark wings (compare with smaller siskins). Female and immature are duller, but dark slaty hood and golden tones to back are distinctive. Compare with Gray-hooded Sierra-Finch to south and Peruvian Sierra-Finch to north.

Stripe-backed Bittern
Botaurus involucris
Very small, striped buffy heron of wetlands and lake edges with dense reeds and rushes. Boldly striped back pattern is distinctive. In flight shows contrasting broad rusty trailing edge to wings. Usually seen as single birds hidden in reeds or making short flights low over reeds or across patches of open water. Clambers easily and stealthily; hunts from perches over water, where sits patiently before stabbing at fish. Mostly silent.
