Cape Sparrow (Passer melanurus) lives in urban areas across Southern Africa. It feeds on seeds and insects. Its conservation status is Least Concern.
Fascinating facts about the Cape Sparrow
- Cape sparrows usually breed in loose colonies of 50-100 birds, each pair laying a clutch of three or four eggs, though the range can be two to six depending on food availability. Both parents share incubation duties, swapping the eggs every ten to fifteen minutes, and the incubation period lasts 12-24 days.
- Nests are lined with aromatic leaves like wolbossie, thyme, and camphor, a habit that suggests the birds are using natural chemicals to fend off parasites. This behavior shows how the species exploits its environment not just for food but also for disease-defence.
- Genetic studies show the Cape sparrow split from its nearest relatives over 5 million years ago, making it one of the earliest branches of the Passer genus. Its calls differ from the house sparrow that now lives alongside it.
- Cape sparrows form nomadic flocks of up to 200 birds. In Johannesburg, observers have noted smaller groups of 20-30 birds that stand with tails on the ground, then hover 30-60 cm above it in a silent display never seen in other sparrows.
- Groups of 20-30 Cape sparrows break from larger flocks to stand on the ground with tails down and heads raised, sometimes hovering a short distance above. The silent, non-aggressive gatherings are unique among sparrows, and their purpose remains unknown.

About the Cape Sparrow
In the sun-baked landscapes of southern Africa, the Cape Sparrow flits with effortless charm, its earthy plumage blending seamlessly into the rust-hued terrain as it darts between scrubby bushes and rocky outcrops. With a twitch of its chestnut-crowned head, the sparrow navigates its arid domain, its sharp, black bill probing the dusty crevices for hidden morsels and sweet, succulent seeds. As it alights upon a weathered branch, its gentle, melodic trills fill the air, a soothing serenade to the harsh yet beautiful world it calls home.
