Barred Parakeet
Bolborhynchus lineola
Small, fast-flying parakeet of humid evergreen forest in foothills and highlands, especially in areas with seeding bamboo. Usually seen in pairs or small groups flying high overhead; rarely seen perched. Note pointed tail, fast and slightly bounding flight, and habitat (no other small parakeets occur in highlands of Mexico and northern Central America). Blackish barring on upperparts only apparent with a good view.
识别特征
The barred parakeet is about 16 cm (6.5 in) in length and has a weight of about 42 to 52 grams. It is mostly green and has black stripes (or bars) over its upper-parts, except on the top of the head. Its lower-parts are olive-green with very dark green stripes on its sides. The shoulder of its wings is black, there is some blue on the under-side of its wings, and its tail is dark green. The irises are dark brown and its beak is horn coloured. Its legs are pink. Juveniles have less-marked dark stripes, which darken with age. Males and females are generally similar in external appearance, but males may sometimes have more marked black stripes than the female. Usually, however, there is no discerning trait to differentiate sex and sexing must be done surgically or through blood tests. The two subspecies differ in the prominence of the dark stripes.

Horned Sungem
Heliactin bilophus
Stunning hummingbird with a short straight bill. Males have a dark blue crown with red, blue, and gold tufted “horns” on the side. Otherwise largely metallic green above and white below with a black throat. Females have a green cap and lack the horns. Found in riverine belts and open savanna grasslands; may venture into adjacent human-modified habitats.

Comoro Green-Pigeon
Treron griveaudi
Chunky, medium-sized pigeon that is mostly pale green with black wings and a pale wing stripe. Flight is very fast and direct. Sometimes found alone, though more often in small groups. Widespread but erratic; local abundance linked to the availability of fruit, its main food. Found in humid forest, secondary forest, and plantations. Endemic to the island of Mohéli in the Comoros. Voice is a quiet but maniacal combination of sputters, whistles, and cackles. Easily identified, as it is the only green pigeon within its tiny range.

Yellow-crowned Bishop
Euplectes afer
Dumpy with a short tail. Breeding males are yellow apart from black throats, cheeks, belly, and wings. The female and nonbreeding male are similar; streaky and sparrowlike with a white eyebrow and throat. Found in wet areas with tall grass. Native to sub-Saharan Africa, now established in Iberia, Jamaica, and Puerto Rico. Gives dry, buzzing calls and a high-pitched “ts’ee”; breeding males also give an odd hissing song.
