Comoro Thrush

<em>Turdus bewsheri</em>, the Comoro thrush, is a medium-sized passerine bird in the family Turdidae endemic to the Comoros archipelago, occurring across Grande Comore, Anjouan, and Mohéli islands. It belongs to the cosmopolitan thrush genus Turdus, which contains over 80 species distributed worldwide. The Comoro thrush inhabits forests and woodland edges across a range of elevations on the islands, from lowland coastal areas to montane forest zones. Like other true thrushes, it is an omnivore typically feeding on invertebrates, berries, and small fruits found in leaf litter and forest understory. The species is classified as Near Threatened by the IUCN, indicating that while not yet considered at immediate risk, ongoing habitat degradation and deforestation across the Comoros pose long-term concerns. Forest clearance for subsistence agriculture and charcoal production continues to reduce suitable habitat across all three islands. The Comoro thrush is generally considered relatively adaptable compared to more specialist endemics, tolerating some degree of forest degradation. However, continued habitat loss could elevate its threat status in future assessments. Biological traits including precise body measurements, lifespan, and clutch size data remain poorly documented compared to continental thrush species. Its melodic song is a characteristic feature of Comoran forest soundscapes.
