Frilled Coquette
Lophornis magnificus
Tiny hummingbird that is gray and green above and gray below. Like other coquettes it has a white bar across the rump. Males are astonishingly pretty with an orange crest, a ruff of white and green feathers on the neck, and a red bill with a black tip. Females have a white belly, and spotted throat, lacking the male’s crest and orange bill. Found at forest edges, in second growth habitats and in wooded savanna.
识别特征
The frilled coquette is one of the smallest birds alive. It is 7.1 to 7.7 cm (2.8 to 3.0 in) long and weighs an average of 2.66 g (0.094 oz). Both sexes have a short, straight, black-tipped red bill and bronzy green upperparts with a white band across the rump. Adult males of this striking bird have a long, rufous-orange erectile crest and green and white fan-shaped cheek feathers. Its forehead and throat are iridescent green and the rest of the underparts grayish green. Its central tail feathers are bronzy green and the rest rufous with bronzy green tips and edges. The adult female does not have the male's crest or cheek tufts. It has a whitish throat with rufous discs and dark crescents. It underparts are grayish green like the male's, but the tail is overall dark bronze with rufous ends. Juveniles are similar to the adult female.
分类信息

分布与栖息地
The frilled coquette is found in eastern and southern Brazil, from Espírito Santo south to Rio Grande do Sul and west almost to Bolivia and Paraguay. It has occasionally been recorded as far north as Alagoas. It inhabits semi-open to open landscapes such as the edges of humid forest, secondary forest, coffee plantations, gardens, and cerrado. In elevation it ranges from sea level to 1,000 m (3,300 ft).

行为
The frilled coquette makes some seasonal dispersal, apparently after the flowering and nesting season.<p>The frilled coquette feeds on small arthropods and on the nectar of a wide variety of small flowering plants. It catches insects by hawking from a perch 2 to 5 m (7 to 20 ft) above the ground. It defers to larger hummingbirds.<p>The frilled coquette's breeding season spans from August to March. The female makes a cup-shaped nest of plant down and moss decorated with lichens on the outside. It typically places it like a saddle on a branch of a bush or small tree 2 to 5 m (7 to 20 ft) above the ground. The female incubates the clutch of two white eggs; incubation lasts 12 to 13 days and fledging occurs about 20 days after hatch.<p>The frilled coquette is mostly silent. It gives "a short 'tsip'" while feeding. Its wings make "a low bee-like humming" when hovering.

Pale White-eye
Zosterops flavilateralis
A small, sharp-billed warbler-like bird. Note the yellow underparts and the narrow white spectacles around the eyes. Found in dry thorn savanna, woodland, and scrub. Usually in hyperactive flocks, and often joins mixed flocks. Very similar to African Yellow White-eye, but shows less yellow above the bill, looks more washed-out overall, and prefers drier habitats. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes.
Copper-rumped Hummingbird
Saucerottia tobaci
Fairly common and very territorial small hummingbird. Glittering green head and underparts, coppery rump (absent in northwest mountain subspecies), bronzy to rufous brown undertail, slightly curved and medium-sized bill with red lower mandible, and forked blue tail. Female similar to male but with dull brown belly. Usually in forest edges, second growth woodland, and gardens. Flight call a trill; song a slow, high-pitched four-note “e-ri-caa.” Distinguished from Steely-vented Hummingbird by lack of blue rump coverts; from male emeralds by longer and more curved bill; and from Blue-chinned Sapphire by forked (not rounded) tail and lack of bluish tinge on chin and body.
Red Knot
Calidris canutus
Stocky, medium-sized shorebird with relatively short bill and legs. Combination of shape, overall color, and bill size usually distinctive. Beautiful breeding plumage shows entirely salmon-orange underparts and silvery wings with intricate patterning. Nonbreeding is plain gray with pale underparts and a white eyebrow; juvenile similar but with scaly pattern on wings. Usually shows dark barring on flanks. Legs are dull greenish or gray. Widespread and fairly common, breeding on high Arctic tundra and wintering on coastlines around the globe, as far south as Tierra del Fuego. Most numerous on beaches and mudflats; less common inland. Occurs in flocks, often mixed with other shorebirds. Compare with larger, lankier, longer-billed Great Knot in Asia and Australia. Feeds on a variety of small invertebrates; West Atlantic population reliant on horseshoe crab eggs during spring migration.
