Amazonian Grosbeak
Cyanoloxia rothschildii
Chunky, stout-billed bird of humid evergreen forest and edge in tropical lowlands. Occurs from throughout much of the Amazon basin (east of the Andes). Usually found in pairs, often skulking at low to middle levels in lush vegetation. In typical views, looks simply dark. Note the very stout bill and broad tail, which can be twitched side to side. Male is deep blue-black overall. Female is rich dark brown overall. Sharp squeaky call often doubled and rather distinctive.

分布与栖息地
The Amazonian grosbeak is the most widely distributed grosbeak in the Amazon Basin. It is found from eastern Colombia south through eastern Ecuador and Peru to central Bolivia, from southern and eastern Venezuela east through the Guianas, and in all of Amazonian Brazil. In Venezuela it ranges in elevation from near sea level to 1,000 m (3,300 ft), in Peru to 1,400 m (4,600 ft), and in Bolivia mostly to 1,000 m (3,300 ft) and rarely to 1,200 m (3,900 ft). It inhabits the understory and edges of humid primary and tall secondary forests.

It appears to nest between January and June. The nest is a cup of dried leaves and fern stems and the clutch size is two.<p>The Amazonian grosbeak's song has been rendered as "pee tee-tu-tu-ti-pee'chee". Its call is "a sharp, harsh, dry tchit".

Germain's Peacock-Pheasant
Polyplectron germaini
Small compact brown pheasant with bright red facial skin and iridescent sapphire spots all over the body, with longer green spots on the tail. Inhabits forests with dense cover from the lowlands up into the foothills and lower montane areas. Generally shy and reclusive and very difficult to see well.
Black-billed Mountain-Toucan
Andigena nigrirostris
Distinctive toucan of montane forests in the Andes from Venezuela to extreme northwest Peru. Easy to identify with black cap, dark bill, white throat, powder blue belly, and mostly brownish upperparts. Occurs from 1,500-2,500m, typically below the elevational range of Gray-breasted Mountain-Toucan but occasionally some overlap. Uncommon; usually found singly or in pairs in the forest canopy, often around fruiting trees.
White-shouldered Ibis
Pseudibis davisoni
Dark, burly medium-sized ibis. Restricted pale patches on the nape and shoulder distinguish this from all-dark ibises. Habitat preferences differ somewhat in two parts of disjunct range; Bornean birds favor mature riparian forests, while Indochinese birds are generally found in wet or flooded openings in dry forest and wooded plains. Forages singly, in pairs, or in small groups. Often disperses with the arrival of seasonal rains. Gives loud, resonating honks and croaking roars. Declining across range; status of Bornean population especially tenuous.
