Blue Quail
Synoicus adansonii
Tiny, dark grassland quail. Males are dark blue and chestnut, with a bright white throat. Females are dark brown with heavy barring below. Found in moist grasslands, often in seasonally flooded areas. Probably nomadic or migratory, appearing with the onset of the rainy season. The common vocalization is a two- or three-part whistled call: “chee-chew” or “chee-chee-chew.” Smaller than other quail; male separated by blue coloration and female by barring below.
识别特征
The blue quail is 14–16.5 cm (5.5–6.5 in) long and weighs 43–44 g (1.5–1.6 oz). Its legs are yellow. The colour of the eyes varies from brown in the juvenile to red in the breeding male. The species is sexually dimorphic. The male's plumage is mostly dark slaty-blue, with rufous patches on its wings. The male has a black beak, a brown head, and a black and white throat. There is a white patch on its breast. Its flight feathers are brown. The forehead, sides of the head and neck, and flanks of the female are orange-buff. Its crown is brown, with black mottles. The female's beak is brownish. Its underparts are buff, with black bars, and its upperparts have black and rufous mottles and streaks. The juvenile is similar to the female.
分类信息
The blue quail was described as Coturnix adansonii by Jules Verreaux and Édouard Verreaux in 1851. It is named after the French naturalist Michel Adanson. The species has had a complex taxonomic history, being classified into the genus Coturnix, then Synoicus, then Excalfactoria. Phylogenetic evidence supports it belonging in an expanded Synoicus that, alongside the king quail (S. chinensis) also includes the Snow Mountains quail (S. monorthonyx) and brown quail (S. ypsilophorus). The IOC World Bird List and Handbook of the Birds of the World now both place it in Synoicus. Sometimes considered a subspecies of the king quail, the species is monotypic.

分布与栖息地

行为
The blue quail is migratory, changing regions at the start of the rainy season and again early in the dry season. It eats seeds, leaves, insects, and molluscs. Its voice is a piping whistle, kew kew yew. It also gives the whistle tir-tir-tir when it is flushed. The blue quail is monogamous. The nest is a scrape. Eggs are usually laid at the beginning of the rainy season. Three to 9 olive-brown eggs are laid in a clutch. The eggs have reddish and purplish freckles. They are incubated by the female for around 16 days. The chicks are precocial.

Puerto Rican Tody
Todus mexicanus
A tiny, brilliant-green resident of wooded habitats. There are no similar species within its range. Typically perches at low to middle levels in the forest and sallies forth to snag insects from the undersides of leaves. When not actively pursuing a meal, sits rather motionless. Most active, and thus most easily seen, when the sun comes out following rain. Most often first detected by its voice: a loud buzzy “zhip, zhip.”
Three-banded Courser
Rhinoptilus cinctus
Elegant, cryptic, long-legged, upland shorebird. Shows a dark upperwing and a largely white underwing in flight. Found in savanna and woodland, including some miombo. Nocturnal species that spends the day roosting under a thick bush. Calls at night with a repeated metallic “chik.” Somewhat similar to Double-banded Courser but is nocturnal and has a more complex and striped head and chest pattern.
Lilac-breasted Roller
Coracias caudatus
A chunky, large-headed bird with a lilac breast, rusty cheeks, and spring-green crown. Singles and pairs sit on prominent perches in open woodland and lightly-treed grasslands. It has an amazing display flight which includes side-to-side rolling, which gives rollers their name. Mostly quiet, but sometimes calls a loud guttural “gwhaaak, gwhaaak”. European Roller is chunkier, has a blue breast and face, and has a shorter, square-tipped tail.
