Identification

How to recognise it

Similar to the Red-winged Starling but slimmer, with a well-graduated tail and more slender bill. The adult male is a deep violet-blue-black gloss; the female is duller, with grey on the head and breast.

Calls & Song

What it sounds like

Perched flocks give a loud but rather tuneless warble that can continue for long periods. In flight, members call harsh slurred notes, "teeeo" or "teeoo".

Distribution

Where you'll find it

Small flocks are locally common around highland forests and alpine moorlands but range widely from 1,400 m to 4,500 m. In our area they are seen all around the Park, but commonly in the highlands from Sine Camp up to Margaretha Camp, Wiseman and Kihalo.

Behaviour — Feeding

Diet

Eats fruit, grains, seeds, insects, locusts, ground beetles, grasshoppers, crickets, moths and butterflies, and also invertebrates and berries.

Breeding & Nesting

Nesting

Nests in rock under waterfalls to avoid predators, laying 3–4 eggs that hatch after 11–13 days of shared incubation (though only the female stays on the nest at night). Breeding is mostly February to early July.

Movement & Local Notes

On the trail

Presumed mostly resident, with extensive altitudinal movements and some local wandering. In the community, farmers read the flocks' seasonal movements as a sign of the farming calendar.
