Perija Metaltail
Metallura iracunda
Small, short-billed hummingbird found only in the Perijá Mountains, which straddle the border between Colombia and Venezuela. Similar to the more common Tyrian Metalail, but larger with a longer coppery (not bluish) tail; male is also darker and female has speckles on the throat. Inhabits scrubby areas in and around high elevation grasslands near tree line, typically at higher elevations than Tyrian Metaltail, but there is some overlap.

分布与栖息地
The Perijá metaltail is found in the Serranía del Perijá, which straddles the border between northern Colombia and northwestern Venezuela. It inhabits the varied landscapes of the different peaks within the mountain range, including open bushy terrain, karstic elfin forest, bamboo stands, grassy páramo, and areas of sandstone outcrops. In elevation it ranges between 2,400 and 3,200 m (7,900 and 10,500 ft) in Colombia and as low as 1,850 m (6,100 ft) in Venezuela.

Socotra Cisticola
Cisticola haesitatus
Small, pale brown, heavily streaked cisticola. Endemic to Socotra, where it inhabits low shrublands and other habitats with significant bushy cover, mostly at low elevations. The song is a long series of dull “zit” notes, often given in flight; very similar to the song of the widespread Zitting Cisticola, which is not found on Socotra. Within its range, can only be confused with Socotra Warbler, but easily distinguished by the paler coloration and well-defined streaking.
Ijima's Leaf Warbler
Phylloscopus ijimae
An uncommon migrant songbird through Taiwan, rarely encountered anywhere away from breeding grounds on Izu and Tokara Islands, Japan. Olive above and whitish below; best distinguished from similar species by narrow bill with yellowish lower mandible, brownish-pink legs, and weak head pattern. Prefers mature coastal broadleaf forests but uses bamboo patches and conifers during migration as well. Smaller than Eastern Crowned Leaf Warbler, with thinner bill and no crown stripe. Song consists of a series of trills; calls, given often, include a descending “twee” or quiet “pee.”
Golden-shouldered Parrot
Psephotellus chrysopterygius
Slender, long-tailed parrot restricted to a tiny range in tropical savanna woodland in far northern Queensland. Male a striking turquoise color, with red lower belly, tiny black cap, and yellow forecrown. Wings pale grayish brown with yellow band. Female primarily green with turquoise wash on face and underparts. This species digs tunnels in termite mounds in order to breed.
