Ochre-breasted Foliage-gleaner
Anabacerthia lichtensteini
Medium-sized foliage-gleaner with a short bill and attractive head pattern giving it a “cute” look. The crown and mask are gray-brown contrasting with a buffy-yellow eyebrow and throat. Buffy and unstreaked below and rufous-brown above. Found in the upper levels of forests and second growth. The song is a short fast trill.
识别特征
The ochre-breasted foliage-gleaner is 15 to 17 cm (5.9 to 6.7 in) long and weighs 18 to 24 g (0.63 to 0.85 oz). It is a medium-sized furnariid with a wedge-shaped bill that is the shortest in its genus. The sexes have the same plumage. Adults have an ochraceous eye ring and sharply defined supercilium, a dark brownish band behind the eye, dull rufous-ochre ear coverts, and pale brownish lores. Their crown is dull gray-brown with vague paler streaks, their back rufescent brown, and their rump and uppertail coverts a slightly lighter rufescent brown. Their tail is mostly rufous with rufescent brown outer webs on the innermost pair of feathers. Their wings are rufous brown with duskier tips on the flight feathers. Their throat and malar area are bright ochraceous buff, their upper breast a richer ocraceous buff, and the rest of their underparts a duller ocraceous buff. Their iris is brown, their maxilla brownish gray, their mandible light gray, and their legs and feet greenish gray. Juveniles have less uniformly colored underparts than adults, and those feathers have grayish tips.
分类信息
The ochre-breasted foliage-gleaner was previously included in genus Philydor but a 2011 paper made it plain that it did not belong there. The same paper found the white-browed foliage-gleaner (A. amaurotis) and the ochre-breasted to be sister species.<p>The ochre-breasted foliage gleaner is monotypic.

行为
The ochre-breasted foliage-gleaner is a year-round resident throughout its range.<p>The ochre-breasted foliage-gleaner feeds on arthropods. It usually forages as part of mixed-species feeding flocks, and usually from the forest's mid-storey to its canopy. It acrobatically gleans and pulls for its prey in dead leaves, debris, and branches.<p>Nothing is known about the ochre-breasted foliage-gleaner's breeding biology.<p>The ochre-breasted foliage-gleaner's song is a "series of up to 10 estr. high, piercing 'zipzip---' notes". Its call is a "short, very high, inhaled trill".

Red-collared Widowbird
Euplectes ardens
A small widowbird. The breeding male is jet black, with a crimson band across the breast, and a 20-centimeter floppy graduated tail. All-black birds and birds with a reduced crimson band, also occur. The female and non-breeding male have dark streaked upperparts, pale unstreaked or faintly streaked underparts, and a yellowish eyebrow and face, and lack the long tail. Pairs breed in open grassland, savanna, scrub, and cultivated areas. The species may flock, often with other seedeaters, and move locally when breeding is over. Breeding males are distinctive, but non-breeding males and females can be confused with many other species. Can be tentatively identified by lack of red or yellow in the wing, along with a buffy breast that is unstreaked or only lightly streaked.
Variable Limestone Babbler
Gypsophila crispifrons
A large, chunky, scraggly-looking babbler found in limestone hills covered with forest. Gray and brown overall with heavy streaking on the head, back, and throat. An odd white morph shows a variable amount and distribution of bright white on the head and breast. Forages close to the ground, often in and around rocky cracks and crevices. Song is a loud, ringing, rather hoarse-sounding sequence of whistled notes including some repeated phrases, sometimes given as a duet by a pair. Also gives harsh “grrr” calls. Similar to Streaked Wren-Babbler, but larger and longer-tailed, lacking white spots on the shoulder.
Northern Boobook
Ninox japonica
A slender brown owl with comically expressive golden eyes. Dark brown above and white below with long dark streaks on the breast. Its long tail and streaked undersides give it a distinctly hawklike profile in flight. Usually found in forests but occasionally shows up in small parks, especially on the coast during migration. Hunts flying insects at night and sometimes found around artificial lights. Gives an extended series of paired hoots.
