Dusky-billed Parrotlet
Forpus modestus
A tiny, bright green parrot found throughout much of the Amazon basin. Dusky-billed has darker green plumage and a dark upper bill compared to the very similar Blue-winged Parrotlet. Dusky-billed is also less likely to be found around clearings than Blue-winged. Often first noticed by the incessant high-pitched, buzzy calls given by flocks, not as high-pitched and piercing as the calls of Blue-winged.
分类信息
The dusky-billed parrotlet was previously described by the name Forpus sclateri by Jean Cabanis in 1849 but later reassigned to the genus Psittacula as Psittacula modesta by George Robert Gray in 1859. However, because the name modesta was assigned to at least two closely related birds of the genus Psittacula, the dusky-billed parrotlet was reverted to F. sclateri. As of 2006, the binomial name for the dusky-billed parrotlet is Forpus modestus, with F. m. sclateri as a subspecies.<p>It has been suggested that the dusky-billed parrotlet is basal to all other species of the genus Forpus based on diversification and speciation rates and patterns.

分布与栖息地
The dusky-billed parrotlet is found in the Amazon Rainforest in South America, where it is locally fairly common; it also occurs in the Andes and the Amazonian foothills, the Amazon River outlet, and Marajo Island.<p>Dusky-billed parrotlets prefer lowland tropical rainforest edges and clearings, riparian zones, secondary habitats, and savanna. They seem to favor seasonally-flooding forests. They are not found at altitudes higher than 1,000 metres (3,300 ft) above sea level.

行为
Dusky-billed parrotlets are usually found in flocks of up to 100 birds outside of their breeding season; otherwise, they are seen mostly in pairs. They are very social, and conspicuous in their habitat. Calls are high-pitched notes or soft wheezing sounds, made while in flight or perched.<p>Dusky-billed parrotlets typically breed during July. Clutch size is unknown, but eggs are small, white, and roughly spherical. They nest in tree cavities or similar structures.<p>Dusky-billed parrotlets' diet consists of approximately 10% seeds, buds, and blossoms and 90% berries and fruits,. Grass is occasionally eaten as well. Dusky-billed parrotlets have also been observed to eat clay as a primary source of minerals.
保护状况
According to the IUCN Red List, dusky-billed parrotlets are a species of Least Concern. Their population size is unknown, but is believed to be stable.<p>Unlike many members of the genus Forpus, they are not captured for the parrot trade, and they are relatively unaffected by deforestation. There are many protected areas throughout their range.

Chilean Flicker
Colaptes pitius
No similar species in its range. Found in woodland, forest, matorral, and farmland with taller trees and hedges; often feeds on the ground. In some areas of central Chile nests in colonies in dirt bluffs, such as along roadsides; elsewhere usually nests in holes drilled in trees. Note the gray crown and plain buffy face (with dark whisker on male), big white rump patch, and yellow shafts to wing feathers (mainly visible in flight). Loud shrieking calls sometimes draw attention.
Abyssinian Ground-Thrush
Geokichla piaggiae
Large, brown-backed, orange-breasted thrush with bold white wingbars. Found in the understory of montane forest. Generally shy and scarce. The song is a musical and typically thrush-like, a chatty and cheerful series of whistles and chuckles. The call is a very thin, rising trill. Very similar to Orange Ground-Thrush, but has a different pattern on the head: an orange crown, a plain face, and a complete white eye-ring.
Papuan Frogmouth
Podargus papuensis
Very large nocturnal bird with "frog-like" bill and long tail. Inhabits edges of dense forests, including mangroves. In daytime, often roosts above water. Primarily gray-brown with barred underparts and tail. Distinguished from other frogmouths by very large size. Call is a repetitive, low-pitched "oo-oo-oo-oo."
