Yellow-green Grosbeak
Caryothraustes canadensis
A well-named grosbeak that is olive-greenish above and brighter yellow below, with a distinctive black face and a stout bill with a silver base. Disjunct range stretches from eastern Panama to southeast Brazil. Occurs in the subcanopy of lowland forest, up to around 1,000 m. Typically found in small groups, sometimes as a part of a larger mixed-species flock. Often draws attention to itself with piercing buzzy and squeaky calls. Not likely confused, but compare with female Red-and-black Grosbeak, which has entirely black head.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the yellow-green grosbeak in his Ornithologie based on a specimen collected in Cayenne in French Guiana. He used the French name Le Gros-bec de Cayenne and the Latin name Coccothraustes Cayanensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the yellow-green grosbeak. Linnaeus included a terse description, used the binomial name Loxia canadensis and cited Brisson's work. Linnaeus mistakenly claimed that the species occurred in Canada rather than Cayenne and introduced the specific name canadensis for Canada where the bird does not occur. This species is now placed in the genus Caryothraustes that was introduced by the German naturalist Ludwig Reichenbach in 1850. There are four subspecies.

Romblon Boobook
Ninox spilonotus
A rare medium-sized owl of lowland and foothill forest on Tablas, Romblon, and Sibuyan islands. Upperparts, chest, and head dark brown and indistinctly barred. Underparts reddish brown. Note the long whiskers around the face and the bright yellow eyes. Probably the only owl in its range except for Mantanani Scops-Owl, but Romblon Boobook is reddish rather than gray and lacks the black line around the face. Song is a phrase of three notes, “wik weu-weu,” with the second and third being descending rasping notes.
Elliot's Pheasant
Syrmaticus ellioti
Pale and stocky-looking pheasant of hill forests with dense undergrowth; generally scarce due to poaching throughout its range. Male is unmistakable: mostly brown above with a white belly, silvery head, bright red face, and a long pale gray tail with thick russet bands. Female is smaller and shorter-tailed with a faded version of the male’s patterning. Can be quite tame in areas where are protected and fed by rural communities.
Sumatran Ground-Cuckoo
Carpococcyx viridis
Incredibly elusive and rare, this is a highly sought-after ground-dweller. Found only in primary hill forest (300-1400 meters) in western Sumatra. Unmistakable if seen well; note long broad tail, burly chest, dark head, long legs, finely barred breast, and brightly-colored blue-and-pink bare facial skin. Like many other terrestrial birds, tends to run away when spooked. Very difficult to see, and best detected by its mournful, high-pitched, and slightly hollow whistled song: “gwheuw-oh-eewo’eh!” Also gives a harsh, buzzy call that sounds like someone blowing their nose.
