Pennant-winged Nightjar
Caprimulgus vexillarius
Breeding males have extraordinary “pennants” growing out of their wings. Non-breeding males are still distinctive due to the huge white patches on the wings. Females are very drab, and lack white in the wing or tail, unlike most nightjars. This is a migratory species that is found in many different habitats on migration and during the non-breeding season. Breeds in moist savanna and broadleaved woodland, especially miombo. Song is a slow, squeaky trill. Female is similar to Standard-winged Nightjar, but is larger and has more barring in the wings.
识别特征
The male of the species is characteristic in having a broad white band over the otherwise black primaries. In addition the males acquire a striking 2nd primary feather during the breeding season. These pennant feathers grow to greater lengths in successive years, up to twice the body length. They are dropped or broken off quickly upon completion of breeding. With the distal (9th) and proximal (1st - 3rd) primaries being longest, the wings of male birds are distinctly angular.

分布与栖息地
Their preferred habitat south of the equator is plateau woodlands, especially Miombo, where they are partial to stony or boulder-strewn hillsides. They are observed as bi-annual and social passage migrants along the Kenyan Rift Valley and Lake Victoria regions, and spend the non-breeding season in subtropical savanna from Nigeria to Sudan.

Pfrimer's Parakeet
Pyrrhura pfrimeri
Long-tailed parakeet. Note the maroon face bordered by a bluish crown and cheeks and the scaly blue breast. An inhabitant of deciduous forests on rocky outcrops, where it is encountered in small flocks at fruiting trees, occasionally descending to the ground. Calls similar to other members of the White-eared Parakeet group.
Johnson's Tody-Flycatcher
Poecilotriccus luluae
Small, colorful flycatcher of Peru’s eastern Andes; found mainly in the northern part of the country, but there is at least one isolated population much farther south. Combination of red head, white chin, gray collar, and yellow belly is distinctive. Does not overlap with Rufous-crowned Tody-Flycatcher, which is only found north of the Marañon River. Inhabits dense thickets and bamboo stands at the edge of cloud forest. Song is a series of short rattles, often given as a duet.
Rusty-necked Piculet
Picumnus fuscus
Uncommon piculet of riverine and flooded forests, found only in a very limited area along the Brazilian/Bolivian border. Usually seen alone or in pairs below the forest canopy. Plumage generally brownish, but note the black top of the head. Male and female are very similar, except for the orange-reddish feathers in the male’s crown. Voice consists of 5–7 short, sharp whistles, dropping at the end: “tzi-tzi-tzí-tzí-tzíu.”
