African Pygmy Kingfisher
Ispidina picta
Tiny, gem-like, woodland kingfisher. Note the orange face with a purple cheek mark and the narrow, dark blue crown. Found in the understory of woodland, thickets, and some forests. Inconspicuous bird that sits motionless for long periods before darting after prey. Call is a harsh “tsik,” often given in flight. Similar to Malachite Kingfisher, but smaller, has more orange on the face, and prefers upland habitats. Very similar to African Dwarf-Kingfisher, but pygmy-kingfisher has a dark crown.
识别特征
The African pygmy kingfisher is 12 cm (4.7 in) in length. The sexes are alike. It is a very small kingfisher with rufous underparts and a blue back extending down to the tail. The dark blue crown of the adult separates it from the African dwarf kingfisher. The smaller size and violet wash on the ear coverts distinguish it from the similar malachite kingfisher.<p>The natalensis subspecies occurring in the south of the range has paler underparts and a blue spot above the white ear patch. Juveniles have less extensive violet on their ear coverts and a black rather than orange bill. The call is a high-pitched insect-like "tsip-tsip" given in flight.
分类信息
The African pygmy kingfisher was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Todier de Juida in his catalogue of the Planches Enluminées. The type locality is Saint Louis, Senegal. The African pygmy kingfisher is now placed in the genus Ispidina that was introduced by the German naturalist Johann Jakob Kaup in 1848. The specific epithet picta is from the Latin pictus meaning "painted". Some texts refer to this species as Ceyx pictus.<p>There are three subspecies:

分布与栖息地
The African pygmy kingfisher is distributed widely in Africa south of the Sahara, where it is a common resident and intra-African migrant. It is absent from much of the horn of Africa, and also the drier western regions of Southern Africa. It is found in woodland, savanna and coastal forest, and it is not bound to water. It is usually found either singly or in pairs and is secretive and unobtrusive.

行为
African pygmy kingfishers nest in burrows that are dug by both sexes in sandy soil banks or into a ground termite nest. The burrows are between 30 and 60 cm (12 and 24 in) in length. The clutch is four to six white eggs. Both parents care for the young. They can have several broods in a year.<p>The African pygmy kingfisher's diet consists of insects like grasshoppers, praying mantis, worms, crickets, dragonflies, cockroaches and moths. They are also known to take spiders which make up quite a large part of their diet. They also take geckos and lizards that are easily their length and small frogs and even occasionally small crabs. Prey are hunted from low perches and once caught are either crushed in the beak or smashed against the perch.<p>The southern subspecies overwinters as far north as 2°N (DRC, Uganda, South Sudan and Kenya). They are thought to migrate mainly at night; most leave their breeding grounds in March and April, and return in September or October.<p>

Orange-throated Tanager
Wetmorethraupis sterrhopteron
Unique and beautiful rainforest tanager known only from several remote areas of the eastern Andes in northern Peru and southeastern Ecuador. No other Andean bird has an orange throat, black upperparts, and blue wings. Most often encountered in clearings with scattered trees or at the edge of the forest. Pairs or small groups roam widely through the forest canopy, giving loud, far-carrying squeaky calls.
Red-fronted Prinia
Prinia rufifrons
A long-tailed, slim, distinctive warbler of dry country. Gray-brown on the upperparts and whitish below, with white marks on the wing and outer tail. The tail is frequently cocked up and wagged from side to side. Found in dry thorn savanna and thornscrub, usually in pairs. Similar in shape to other prinias, but easily separated by the red forehead. Could be mistaken for some cisticolas, but shows white in the wing, and distinctive tail-wagging behavior. Song consists of long series of a musical or scolding note, sometimes punctuated by short series of a different kind of note; can be similar to Pale Prinia’s song, but generally much more varied.
Yellow Bittern
Botaurus sinensis
Very small heron of marshy, well-vegetated water bodies. Adult pale orangish brown or yellow, depending on the light, with a narrow dark cap. Juvenile darker above with pale feather edges. Can be inconspicuous in dense vegetation, but frequently makes short flights; on flying birds, note dark flight feathers contrasting with pale yellowish wing coverts. Typically quiet, but occasionally gives harsh grating calls when flushed.
