Population justification: Angulo (in litt. undated) states that Lambayeque department definitely holds more that 100 pairs. If only a 1000 ha area holds at least five individuals (we can estimate a rough density of one individual/200 ha), and the available habitat in Lambayeque [between 50-700 m elevation] can be roughly estimated at 250,000 ha, the population would be at least 1,250 individuals. In Quebrada Frejolillo (the famous place to see the White-winged Guan in the wild) in an area of approximately 300 ha, there are at least six birds, which gives an estimate of one bird/50 ha. With this number, the Lambayeque population would be 5,000 individuals and the whole population 20,000 (considering that Lambayeque and Piura together have 1,000,000 ha of suitable habitat). In light of this the population is best considered to number 10,000-19,999 mature individuals, equivalent to 15,000-29,999 individuals in total, rounded here to 15,000-30,000.
Trend justification: Habitat degradation is likely to be driving a slow to moderate decline.
