Yellow Canary
Crithagra flaviventris
A large canary with different-looking males and females. The male has bright yellow underparts, yellow-green upperparts, and a well-marked face pattern. The female is drab gray-brown with streaky underparts, yellowish edges of the wing feathers, and a yellow rump. Pairs and small groups occupy dry rangelands including coastal scrub, Karoo, and arid thornveld, where they are resident and nomadic, moving when food becomes scarce. The larger Brimstone Canary has a chunkier bill than Yellow Canary and prefers moist coastal thickets and woodland.
识别特征
The yellow canary is typically 10 cm in length. The adult male colour ranges from almost uniform yellow in the northwest of its range to streaked, olive backed birds in the southeast. The underparts, rump and tail sides are yellow. The female has grey-brown upperparts, black wings with yellow flight feathers, and a pale supercilium. The underparts are white with brown streaking. The juvenile resembles the female, but has heavier streaking.<p>This species is easily distinguished from the yellow-fronted canary by its lack of black facial markings, and its bill is less heavy than that of other similar African Crithagra species.<p>The brimstone canary, with overlapping range, is a known confusion species.
分类信息
The yellow canary was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the crossbills in the genus Loxia and coined the binomial name Loxia flaviventris. He specified the location as the Cape of Good Hope. The specific epithet flaviventris is from Latin flavus meaning "yellow" and venter, ventris meaning "belly". Gmelin based his account on the "Le Gros-bec jaune du Cap de Bonne Espérance" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson.<p>The yellow canary was formerly placed in the genus Serinus but a phylogenetic study published in 2012 found that the genus was polyphyletic. In the reorganisation to create monophyletic genera, Serinus was split and a number of species including the yellow canary were moved to the resurrected genus Crithagra that had originally been introduced in 1827 by the English ornithologist William Swainson.<p>Four subspecies are recognised:

Its habitat is karoo and coastal or mountain valley scrub. It builds a compact cup nest in a scrub.<p>The yellow canary is a common and gregarious seedeater. Its call is chissick or cheree, and the song is a warbled zee-zeree-chereeo.

Chimango Caracara
Daptrius chimango
Noisy, conspicuous, and often a common scavenger in habitats ranging from towns and cities to open forest, farmland, and beaches; ecological counterpart to crows. Often in groups, locally of tens or even hundreds, feeding on the ground or tumbling and sailing with agile flight; often chases and mobs larger raptors. Plumage brownish overall, often with gingery tones, and with variable paler dappling above and fine barring below. Bold creamy white wing panels and tail base striking in flight.
Great Kiskadee
Pitangus sulphuratus
Large, boldly marked, and boisterous flycatcher. Rather stocky with large head and short tail. Looks bright and contrasty with yellow belly, black-and-white head pattern, and rufous wings and tail. Common and widespread throughout Middle and South America, with limited range in the U.S. (Texas). Occurs in shrubby woodlands, often near clearings or bodies of water. Listen for loud “kis-ka-dee” calls, which helps separate from similar species like Lesser Kiskadee and Boat-billed Flycatcher.
Eastern Yellow-billed Hornbill
Tockus flavirostris
A medium-sized black-and-white hornbill with a big downcurved “banana” bill. Males have a larger bill and pinkish bare skin on the throat; females have a smaller bill and black bare skin. Found locally in dry savanna and thornscrub. The call is a long series of deep clucks that rises and falls. Easily separated from similar black-and-white hornbills in its range by the all-yellow bill.
