The silverbird (Empidornis semipartitus) is an Old World flycatcher native to Eastern Africa, from Sudan to Tanzania. The species is the only member of the genus Empidornis, although it is sometimes placed in the genus Melaenornis.
The silverbird is a stunning flycatcher of open areas west of the Rift Valley, silvery grey above and tawny orange below. Juveniles have black-bordered tawny spots on upperparts, mottled buff and black on throats and breasts. The species is 18 cm (7.1 in) long and weighs 22–23 g (0.78–0.81 oz).
The call of the silverbird uses short phrases which are slightly thrush-like. Sometimes the terminal note is higher and thinner, eee-sleeur-eeee or sweet siursur-eet-seet; also a longer eep-eep churEErip, eep-eep cherip chch chchch eee, embellished with chattering and seep notes.

Rare
Under 5% of wildlife watchers report a Silverbird sighting in Arusha National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 330th most-seen of the 373 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Silverbird in Arusha National Park on a given day, against under 5% in June to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Silverbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 8
Of the 8 parks where we can rate Silverbird sightings, Arusha National Park ranks 8th at under 5%. The best odds are in Murchison Falls National Park (Uganda, about 50%), Serengeti National Park (Tanzania, about 50%) and Kidepo Valley National Park (Uganda, about 40%). All parks ranked.
Same family: Muscicapidae
The closest relatives of the Silverbird that you can see in Arusha National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are African Dusky Flycatcher (about 60%), White-eyed Slaty Flycatcher (about 50%) and African Stonechat (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Silverbird is recorded against all the birds logged in Arusha National Park (7 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
