Striolated Tit-Spinetail
Leptasthenura striolata
Distinctive, diminutive species with a very long spiky tail and a heavily streaked body. Note the rusty crown and narrow white eyebrow. Occurs at forest edges, in Araucaria forest, and in tall second growth, where it forages acrobatically by gleaning. Often accompanies mixed-species flocks.
识别特征
The striolated tit-spinetail is 15 to 16 cm (5.9 to 6.3 in) long and weighs 10 to 11 g (0.35 to 0.39 oz). It is a small, long-tailed furnariid with a short bill. The sexes have the same plumage. Adults have a buff-whitish supercilium on an otherwise grayish face. Their crown is black with buff streaks and their upperparts brown with obvious buff streaks on the back. Their wings are dark brown with paler feather edges. Their tail is mostly brown with some rufous on the outermost feathers; the tail is graduated and appears forked due to the central feather's having reduced inner webs. Their underparts are dull pale ochraceous with brownish speckles on the throat and upper breast. Their iris is dark brown, their bill black with a pinkish gray base to the mandible, and their legs and feet greenish. Juveniles have less distinct streaking and a shorter, less deeply forked, tail than adults.

分布与栖息地
The striolated tit-spinetail is found in much of the southern Brazilian states of Paraná and Santa Catarina, and somewhat into northern Rio Grande do Sul. It inhabits temperate forests dominated by Podocarpus and especially Araucaria, and also riparian thickets and secondary forest. It favors the forest edges and is seldom in the interior of tall forest. In elevation it ranges between 500 and 1,200 m (1,600 and 3,900 ft).

Rufous Hornero
Furnarius rufus
Fairly large ovenbird. Found in almost any open habitat including urban areas. Rufous above and buff below with a contrasting white throat, faint eyebrow, and a dark rufous tail. Song is a loud and rhythmic burst of “kweep” notes often delivered as a duet with wings flapping wildly. Builds remarkable mud nests on trees, buildings, and other human structures.
Peacock Coquette
Lophornis pavoninus
Tiny hummingbird of tepui highlands. Both sexes distinctive: males have long cheek tufts with black spotting, while females are heavily streaked below. Both have a white rump band like other coquettes. Found only in humid forest and scrub in the tepui region. Feeds on nectar by infiltrating territories of larger hummingbirds; also presumably eats tiny insects. May be seen resting on exposed perches. Both sexes are darker than other coquettes in range, and this species typically occurs at higher elevations than others.
Orange-eyed Thornbird
Phacellodomus erythrophthalmus
Medium-sized thornbird with a long tail. Note orange eyes and rufous forehead, throat, and tail while the body is largely brown. Similar to Orange-breasted Thornbird, but has orange rather than dark eyes. Found in pairs on the edge of humid forests, usually near marshes and water bodies where it builds huge stick nests. The song is loud and nasal, usually delivered as a duet.
