White-throated Piping-Guan
Pipile grayi
Large forest guan found in far southeastern Peru, Bolivia, southwestern Brazil, and northern Paraguay, often along rivers. Plumage is mostly black with a white face, crown, nape, and wing patch. It has a bare patch of skin on the throat that may be light blue or white. On older birds this skin patch ends in a wormlike wattle that dangles below the neck. Formerly treated as a subspecies of Blue-throated Piping-Guan; it can be distinguished by the pure white (not buff-streaked) crown and nape, paler blue or white throat patch, and the wormlike wattle (on adults). In some areas, including the Pantanal, individuals with blue and red throat patches can be found; these are likely hybrids with Red-throated Piping-Guan. Mostly arboreal, but sometimes descends to the ground to feed or drink. Song, often given at dawn or dusk, is a rising series of clear whistles. Occasionally rattles its wings loudly in flight.
Identification
The white-throated piping guan is 60 to 69 cm (24 to 27 in) long. The sexes are alike. Most of their plumage is blackish with a light olive to olive green gloss that is strongest on the shoulders, wings, and tail. Their forehead, crown, and nape are white, as are the fringes of their breast feathers. The crown feathers are hair-like and have black or brownish black shafts that show as streaks The outer wing coverts are also white and show as a large patch on the folded wing; the inner coverts have white spots. White to cobalt blue bare skin surrounds the dark reddish brown eye. Bare skin forming a dewlap is also white to cobalt blue. Their bill can be pale blue with a black tip or black with a pinkish and blue base. Their legs are brownish red.
Taxonomy
The genus Pipile has been treated as including anywhere from one to five species depending on the criteria used by the various authors and taxonomic systems. At various times from one to four of them have been treated as subspecies of the Trinidad piping guan (P. pipile). By early 2023, major worldwide taxonomic systems had settled on five species including the white-throated piping guan, which had been considered a subspecies of the blue-throated piping guan (P. cumanensis). The white-throated piping guan is monotypic according to the worldwide systems. However, the South American Classification Committee of the American Ornithological Society retains the white-throated piping guan as a subspecies of the blue-throated.

Range and habitat
The white-throated piping-guan is found from extreme southeastern Peru through north-central and eastern Bolivia into southwestern Brazil and northern Paraguay. It inhabits humid tropical forest of the Amazon Basin including terra firme, várzea, and gallery types, and also cerrado woodland. It almost always occurs within about 100 m (330 ft) of rivers. In elevation it reaches 1,500 m (4,900 ft) in Bolivia.

Other Birds
Torresian Kingfisher
Todiramphus sordidus
Large kingfisher with variable plumage, but always appears as a much greener and browner bird than either Forest or Sacred kingfishers. Note pale spot in front of the eyes that does not extend back over the eye. Occur exclusively among mangroves and adjacent mudflats and rock-shelves.
Bull-headed Shrike
Lanius bucephalus
A small, brightly colored shrike of forest edges and lightly forested fields and gardens. Adult male has pale-bordered black mask, mostly gray back and wings, blackish tail, and warm orange crown, nape, and wash on sides (worn birds less brightly colored). Female has brown back, less obvious mask, rusty crown and nape, and light barring below. Juvenile similar to adult female but lacks pale border around mask. Compared to juvenile Brown Shrike, Bull-headed has warmer orange tones, larger bill, and weaker mask. Song a harsh, raspy collection of notes (including imitations); call is a staccato chatter.
Senegal Parrot
Poicephalus senegalus
Chunky mid-sized parrot with a green back and breast, a gray head, and a colorful belly that shows some geographical variation from yellow to reddish-orange. Found in all types of savanna, including broadleaf savanna, dry thorn savanna, and human-created savanna in the forest zone. Calls are variable sizzling screeches, often given in flight. Similar to Niam-Niam and Meyer’s Parrots, but separated from both by the yellow-orange belly.
