Karoo Prinia
Prinia maculosa
An active warbler with a long graduated tail that is sometimes cocked. It is dull brown above and pale below with extensive streaks and blotches on the underparts that often extend to the throat and belly. Pairs frequent fynbos, strandveld, Karoo shrublands, and gardens, where they are active gleaners of insects, occasionally hopping on the ground. The typical song is a reedy piping “kli” note repeated 4-15 times, with scratchy buzzing notes interspersed. The similar Drakensberg Prinia differs from the Karoo Prinia by having warmer upperparts, yellower underparts, and finer streaks that are mostly restricted to the chest.
识别特征
The Karoo prinia is 13–15 cm (5.1–5.9 in) long, with short rounded wings, a longish tail, strong legs and a short straight black bill. The head has a whitish eyebrow and the upperparts are otherwise brown. The throat and lower face are whitish with dark streaking and the rest of the underparts are yellowish white or yellow with distinct black streaking. The long tail has a dark spot near the end and is typically cocked up at an angle. The feet and legs are pinkish-brown, and the eye is dark brown. The sexes are identical, but juveniles are much yellower below than the adults and less heavily streaked.<p>The calls of this species include a sharp chleet-chleet-chleet-chleet-chleet-chleet, and a fast buzzy tit-tit-tit-tit-tit.<p>The Karoo prinia can only be confused with the closely related Drakensberg prinia, but has less yellow underparts with heavier spotting than that species.
分类信息
The Karoo prinia was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 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 Montacilla maculosa in his catalogue of the Planches Enluminées. Buffon believed that his specimen had come from the Cape of Good Hope. The type locality was changed to Swellendam, in South Africa, by Phillip Clancey in 1963. The Karoo prinia is now placed in the genus Prinia that was introduced by the American naturalist Thomas Horsfield in 1821. The name of the genus is derived from the Javanese prinya, the local name for the bar-winged prinia (Prinia familiaris). The specific maculosa is from the Latin maculosus meaning "spotted".<p>Three subspecies are recognised:

行为
The Karoo prinia builds a thin-walled oval nest with a side entrance from green grass. It is well hidden deep inside a leafy shrub or bush. Breeding is from August to September in areas with winter rainfall, but later (up to December) elsewhere.<p>The Karoo prinia is usually seen in pairs or small groups, typically low in scrub, but sometimes perching on the top of a bush. It actively forages for small insects, with tail cocked and frequently swung side-to-side.
保护状况
This common species has a large range, with an estimated extent of 670,000 km2. The population size is believed to be large, and the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.

Pale-footed Swallow
Orochelidon flavipes
Uncommon swallow in montane forest in the Andes from Venezuela to Bolivia. Similar to the more common Blue-and-white Swallow, but look for the buffy throat and browner flanks on Pale-footed Swallow. Found in flocks, usually not far from forest. Not frequently found around human settlements unlike Blue-and-white Swallow. Occurs from around 2,400–3,200 m.
Pied Honeyeater
Certhionyx variegatus
Medium-sized honeyeater with long decurved bill, nomadic across arid and semi-arid inland Australia. Male black with white belly, wing patches, and tail panels; distinctive patch of blue skin beneath eye. Female and juvenile plain brown, with subtly patterned wings and faint speckles on chest. This species wanders in search of flowering shrubs and can be absent one year, common in large flocks the next. Much larger than Black Honeyeater (which has completely black upperparts). Calls include a slowly whistled phrase of several notes.
Carunculated Caracara
Daptrius carunculatus
Strikingly patterned raptor of the high Andes in Ecuador and southern Colombia. Note pied plumage pattern, white streaks on black breast, and orange face. Immatures are brown with pale patches in the wings (visible in flight). Similar to Mountain Caracara, which may overlap with it in southern Ecuador, but adult Carunculated has breast streaking, and immatures have barring on rump. Inhabits open areas such as paramo and farmland, sometimes congregating in large numbers.
