Population justification:

Based on this species’s apparent rarity, taking the lower quartiles of density estimates of three forest-dwelling congeners, including the Southern Masked-weaver Ploceus velatus, Spectacled Weaver Ploceus ocularis and Holub’s Golden-weaver Ploceus xanthops of 2-8 individuals/sqkm (BirdLife Population Density Spreadsheet; Vernon 1985), and assuming it inhabits 10% of the forest within its range (16,000 sqkm [Global Forest Watch 2021]), the population may fall in the band 3,200-12,800 individuals. This is roughly equivalent to 2,133-8,533 mature individuals rounded here to 2,100-8,600 mature individuals. 

Trend justification: The population is inferred to be in decline owing to the clearance of forest (Global Forest Watch 2021), mainly for agriculture. Between 2000-2018, this species's experienced tree cover loss of 17% (Global Forest Watch 2021), which would equate to a rate of c.10% over three generations. Assuming that the population declines at a similar rate, then the past rate of decline is suspected to fall into the 1-15% band. During the years 2016-2019, this species experienced a forest cover loss of 8.1% across its range (Global Forest Watch 2021). Projected forwards over three generations from 2016, this would equate to a loss of 21%. Assuming that the population declines at a similar rate, then the future rate of decline is suspected to fall in the band of 20-29%.
