Scissor-tailed Hummingbird
Hylonympha macrocerca
Unmistakable hummingbird with long, scissor-shaped tail, overall green with decurved bill and white spot behind eye. Male recalls Violet-fronted Brilliant but with long and forked black tail and blue forehead; female very different, with shorter but still forked tail, white throat, green-speckled chest, and buffy belly, recalling female of Long-tailed Sylph. Found alone inside humid forests or forest borders at low to mid levels, often at Heliconia patches. Voice a short burst “tsi, tsi, tsip.” No similar species in its very limited range. Endemic to the Paria peninsula of northeastern Venezuela.
识别特征
The scissor-tailed hummingbird male is about 19 cm (7.5 in) long including its 9 to 10 cm (3.5 to 3.9 in) tail and weighs 7 to 7.5 g (0.25 to 0.26 oz). Females are 12 to 13 cm (4.7 to 5.1 in) long and weigh 6.5 to 8 g (0.23 to 0.28 oz). Both sexes have a long slightly decurved black bill.<p>Males have a glittering violet forehead and center of the crown; the rest of the crown is a very dark green that is almost black. Their back is metallic grass green with a golden wash on the neck. The throat and breast are glittering emerald green and the rest of the underparts a duller and darker green that becomes blackish on the belly. The flanks have green spots. The blackish purple tail's outermost feathers are much longer and broader than the others. <p>Females are dark glittering green above including the forehead and crown. Their throat and breast are white, spotted with green except in the center of the breast. The belly and undertail coverts are rufous chestnut. The tail is forked but not nearly as dramatically as the male's. Its central feathers are green at the base and steel blue at the end. The outer feathers are cinnamon with beige tips.

Great Cormorant
Phalacrocorax carbo
Large cormorant found nearly worldwide. Note large size, white patch on throat, and lack of crest. Breeding adults show circular white patch on flanks. Immatures typically have contrasting white belly; African "White-breasted" also has extensive white underparts in all plumages. Often spotted standing on rocks or pilings. Dives frequently, feeding on fish. Found in many types of water bodies, ranging from rivers to reservoirs to marine environments; in North America, restricted to coastal North Atlantic.
Pied Falconet
Microhierax melanoleucos
Ridiculously adorable panda-faced raptor, usually found in extended family groups ranging in size from 4 to 20. Perches on exposed snags, sallying forth to catch prey; capable of taking passerines only slightly smaller than it is. Black above and white below, with a white face and a thick black stripe extending down behind the eye. Flight is fluttery but fast; black barring on the wings and tail is only visible in flight, as is a thick black streak on the armpit, reminiscent of Black-bellied Plover.
Pampas Meadowlark
Leistes defilippii
Meadowlark of bunch grass lands of E Argentina and Uruguay. Very similar to the more widespread and common Long-tailed Meadowlark, but in Pampas note the less contrasting, brownish upperparts of male and dark underwings of both sexes. Flight song a quick series of raspy, metallic whistles.
