行为
A.personatus is a mainly insectivorous species that has been observed to hawk or pounce on its prey. Nectar also comprises part of its diet and has been observed occasionally eating fruit.<p>Exclusively pair breeders, consistent with being migratory. A.personatus shows no ecological segregation with A.supercilious but no co operative breeding has been recorded as with other Artamus species. A.personatus breeds throughout most of its distribution range with the exception of eastern and south eastern coastal areas and north of latitude 20°. Usually breeds during spring and summer with annual variation. Breeding frequency is usually once, occasionally twice a year.<p>Similar to the nest of white-breasted woodswallow (Artamus leucorynchus) but less substantial. Usually only one to two metres above the ground, often only a shallow, frail bowl. Has been recorded in stumps, fallen limbs, bush or scrub, fence posts and protruding bark. Nest materials include twigs and grass, with an upper layer of dry or green grass. Both sexes build the nest.<p>Pale greyish white to pale greenish grey to light creamy brown. Measuring approximately 22mm x 17mm, usual shape, tapered oval. Indistinguishable from the White-browed Woodswallow. 2-3 per clutch, less commonly 1-4.

Spot-billed Ground-Tyrant
Muscisaxicola maculirostris
Fairly small and drab terrestrial flycatcher of open rocky and stony slopes and valleys, and adjacent agricultural terraces in the Andes; also locally in desert lowlands mainly in winter. Virtual absence of field marks is a field mark: plumage unrelieved by strong contrast or color. Best told from other ground-tyrants by small size, faint dusky breast streaking, relatively short wings, and much stronger song. Also note yellow base of bill that is visible at close range.
Marcapata Spinetail
Cranioleuca marcapatae
Fairly small, long-tailed bird found in a small range in the Peruvian Andes. Reddish brown above, pale tan below, with a pale eyebrow edged in black and a variably colored crown. In the eastern part of its range, the crown is reddish brown; in its northwestern populations, the crown is creamy white. Has a bolder whitish throat and eyebrow than the similar Ash-browed Spinetail, which is typically found at lower elevations. Marcapata Spinetail forages in low vegetation in cloud forest, especially in thick bamboo. Listen for its song, a descending series of staccato, metallic notes.
Water Pipit
Anthus spinoletta
Breeding plumage grayish above with white eyebrow; breast pale pinkish, mostly unstreaked. Nonbreeding plumage grayish brown above, whitish below with dark streaks; averages smudgier and less well-marked than American Pipit. Sides of tail clean white; compare with dingy white of Rock Pipit in areas of overlap. Song is a long series of repeated high-pitched notes; essentially a slow trill. Call a high, lisping, slightly upslurred "ssiip.” Breeds in mountains on barren, often rocky ground; winters in varied wetland habitats, from lakeshores to salt marshes.
