### Identification The Abd al-Kuri Sparrow is a small, hardy passerine, measuring roughly 13–14 cm. At first glance, it looks like a "ghostly" version of the familiar House Sparrow, but look closer for its distinctively pale, sandy-grey plumage—a perfect camouflage for its sun-bleached island home. The male features a neat, grey crown and a small, well-defined black bib that is far less extensive than that of its mainland relatives. Both sexes sport prominent white wing bars and a slightly more slender, pointed bill than other *Passer* species. If you see a pale, washed-out sparrow with a delicate face in the Socotra Archipelago, you’ve likely found this endemic treasure.
### Habitat & Range This is one of the most range-restricted birds on Earth. It is found exclusively on the tiny, 133-square-kilometer island of Abd al-Kuri, nestled between the Horn of Africa and the Socotra mainland. It thrives in the island's harsh, arid environments, specifically limestone-rich semidesert, rocky hillsides with sparse scrub, and the immediate vicinity of the few small fishing villages. You won't find it anywhere else in the wild.
### Behaviour Observers will find these sparrows to be remarkably social and resilient. They are often seen in small, chatty flocks, foraging with a sturdy, confident hop across the sun-baked ground. They are bold around human settlements, often nesting in the crevices of stone buildings or within the hollows of limestone cliffs. During the heat of the day, they retreat into the shade of rocky overhangs, emerging in the cooler mornings and evenings to socialize and feed.
### Diet A true generalist, the Abd al-Kuri Sparrow survives on a mix of seeds from desert grasses and small invertebrates. They are opportunistic foragers, frequently seen gleaning insects from low-lying vegetation or scavenging food scraps near human dwellings, showcasing the adaptability required to survive on a resource-scarce island.
### Fascinating Fact Because its entire global population is confined to a single, tiny island, the Abd al-Kuri Sparrow is considered one of the most vulnerable bird species in the world. Despite this, it has managed to survive in one of the most arid and isolated environments on the planet, evolving into a distinct species entirely separate from its neighbors on the nearby Socotra mainland!
