Population justification:

This species is described as locally common (Turner and de Juana, 2020). Based on this, taking the lowest of seven estimates for congeners, including Lesser Striped-swallow Hirundo abyssinica and Rufous-chested Swallow Hirundo semirufa of 2 individuals/km² (Vernon 1985), and assuming it inhabits 20% of the forest within its range (9,380 km² [Global Forest Watch 2021]), the population is may be 3,752 individuals. This is roughly equivalent to 2,500 mature individuals. The population is therefore estimated to fall in the band 2,000-3,000 mature individuals.

Trend justification: Population trends have shown evidence of decline over the past few decades, owing to habitat loss and degradation from shifting agriculture and predation by invasive mammals (Dod 1992, Keith et al. 2003, Townsend 2006). No data are available to estimate recent population trends, however, this species is suspected to be declining in line with ongoing habitat loss and degradation. Data from Global Forest Watch (2021) showed that forest cover throughout the species's range declined by 4.7% over the last three generations (10 years). Based on forest loss data between 2017-2020 (Global Forest Watch 2021), and projected forward over three generations, the species habitat is likely to decline by <2%. With the additional threat of invasive predators, the species is suspected to be declining at a rate of between 1-19% over three generations.
