VU
White-crested Guan Penelope pileata

Justification

Based on a model of future deforestation in the Amazon basin, and its sensitivity to hunting, fragmentation and disturbance, it is suspected that the population of this species will decline rapidly over the next three generations, and it has therefore been uplisted to Vulnerable.

Distribution and population
Penelope pileata occurs exclusively in dense lowland humid forest south of the Amazon, from lower rio Madeira to the rio Xingú (Gorotire and Altamira), as far as east Pará (Ourém and Serra dos Carajas) and Maranhão (rio Grajaú, and the Mearim-Pindare river system), in north-central Brazil (Sick 1993, Roth 1997, J. F. Pacheco in litt. 1999, F. Olmos in litt. 1999). Surveys in the late 1980s and early 1990s almost doubled the known range of this species, and it is relatively common in Amazônia (Tapajós) National Park, but scarce around Santarém, Pará (Sick 1993, del Hoyo 1994, Strahl et al. 1994). However, the total population is not considered to be large, and forest destruction has been fairly widespread, especially in Maranhão and Pará (Cleary 1991, Strahl et al. 1994, F. Olmos in litt. 1999).


Population justification
The population is preliminarily estimated to number at least 10,000 individuals, roughly equating to 6,700 mature individuals. This requires confirmation.

Trend justification
This species is suspected to lose 41.5-45.3% of suitable habitat within its distribution over three generations (10 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by 30-49% over three generations.

Ecology
It is apparently restricted to dense lowland forest.

Threats
Forest destruction has been fairly widespread, especially in Maranhão and Pará (Cleary 1991, Strahl et al. 1994, F. Olmos in litt. 1999), as conversion to pasture and settlement of landless agriculturists are part of government-sponsored land reform (F. Olmos in litt. 1999), and is expected to accelerate as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network (Soares-Filho et al. 2006, Bird et al. 2011). There are additional pressures from hunting for food and its status as a prized aviary bird (Delacour and Amadon 1973, Sick 1993, Stattersfield et al. 1998). Proposed changes to the Brazilian Forest Code reduce the percentage of land a private landowner is legally required to maintain as forest (including, critically, a reduction in the width of forest buffers alongside perennial steams) and include an amnesty for landowners who deforested before July 2008 (who would subsequently be absolved of the need to reforest illegally cleared land) (Bird et al. 2011).

Conservation Actions Underway
It occurs in Amazônia (Tapajós) National Park. Conservation Actions Proposed
Organise campaigns to raise awareness and reduce hunting and trapping for trade. Effectively protect Amazônia (Tapajós) National Park and designate further protected areas within its lowland forest range. Monitor population trends at known sites.
