||67-77 cm. Medium-sized, brownish cracid. Pale brown head, becoming darker brown on upperparts, wings and tail. Chestnut-rufous underparts, brighter on belly. White flecking from upper breast to mid-belly and on wing-coverts. Whitish supercilium contrasts with dark eyebrow, which extends around auricular and throat. Dusky facial skin. Red-orange throat and dewlap. Similar spp. Rusty-margined Guan P. superciliaris is smaller with unstreaked wing-coverts and browner belly. Voice Raven-like cry reported. Harsh, loud alarm calls.

This species is listed as Vulnerable because its small population and range are continuing to decrease owing to continuing habitat loss, with additional pressures from hunting.

|Range Description:||Penelope ochrogaster occurs in the "cerrado" (tropical savanna) and northern Pantanal of Brazil (P. de T. Z. Antas in litt. 2012). There are three disjunct populations, one occurring in the Pantanal, another in central Brazil and the third along the São Francisco River (Antas 2006). The largest population is that in the Pantanal (P. de T. Z. Antas in litt. 2012). There had been no records from the São Francisco River since 1913, until the species was observed twice on one of its tributaries in a 1998-2007 survey (Faria et al. 2009). It is moderately common in Poconé, Mato Grosso, including the SESC Pantanal Private Natural Heritage Reserve (P. de T. Z. Antas in litt. 2012); along the Araguaia north of Ilha do Bananal, and along the Paranã, Tocantins (F. Olmos in litt. 2007), where it has been rediscovered within the Cantão State Park. However, the extraordinary paucity of historical and recent records suggests that elsewhere it is highly localised. Moreover, the concentration of recent records suggests that it may have been extirpated throughout much of its formerly large range.|

|Population:||The population is estimated to number 1,000-2,499 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.|
Trend Justification: Trends appear to be "fairly stable", but some decline is suspected on the basis of large scale habitat loss/degradation and hunting pressure (P. de T. Z. Antas in litt. 2012).
|Current Population Trend:||Decreasing|
|♦ Number of mature individuals:||600-1700||♦ Continuing decline of mature individuals:||Yes|
|♦ Extreme fluctuations:||No||♦ Population severely fragmented:||No|
|♦ No. of subpopulations:||2-100||♦ Continuing decline in subpopulations:||Yes|
|♦ Extreme fluctuations in subpopulations:||No||♦ All individuals in one subpopulation:||No|
