科摩罗绣眼鸟

<em>Zosterops mouroniensis</em>, the Comoro white-eye or Mount Karthala white-eye, is a small passerine bird in the family Zosteropidae endemic to the upper montane zone of Grande Comore in the Comoros archipelago. White-eyes of the genus Zosterops are among the most speciose bird genera in the Old World, characterised by the distinctive white feather ring encircling each eye. The Comoro white-eye is restricted to the forests and heath zones of Mount Karthala above approximately 1,500 metres elevation, representing one of the most range-restricted bird species in the Comoros. It typically inhabits montane forest, scrub, and heathland where it forages actively for insects, nectar, and small fruits in the canopy and understory. The IUCN classifies it as Vulnerable, reflecting its tiny range area concentrated on a single active volcano, which makes the entire population susceptible to eruptive events and associated habitat disturbance. Ongoing forest degradation on the upper slopes of Karthala further threatens the species. Biological traits including detailed body measurements, average lifespan, and reproductive parameters remain poorly documented in the scientific literature. The species likely behaves similarly to other Zosterops, forming active foraging flocks and playing a role in pollination and insect control within its montane habitat.
