The mouse-coloured penduline tit or mouse-colored penduline tit (Anthoscopus musculus) is a species of bird in the family Remizidae. At 8 cm (3.1 in) in length, it is one of the two shortest birds native to Africa, alongside the tit hylia.
The mouse-coloured penduline tit was formally described in 1882 by the German ornithologist Gustav Hartlaub under the binomial name Aegithalus musculus. The species is now placed in the genus Anthoscopus that was introduced in 1851 by the German ornithologist Jean Cabanis. The genus name combines the Ancient Greek anthos meaning "blossom" or "flower" with skopos meaning "searcher". The specific epithet musculus is Latin meaning "little mouse". The species is considered to be monotypic: no subspecies are recognised.
This species has an extensive range in Ethiopia, Kenya, Somalia, South Sudan, Tanzania, and Uganda, with an estimated global Extent of Occurrence of 550,000 km2. Its natural habitats are dry savannah and subtropical or tropical dry shrubland.

Rare
Under 5% of wildlife watchers report a Mouse-colored Penduline-Tit sighting in Kidepo Valley National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 256th most-seen of the 332 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Mouse-colored Penduline-Tit in Kidepo Valley National Park on a given day, against under 5% in June–August and October–March, the lowest months. April and May have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Mouse-colored Penduline-Tit sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Mouse-colored Penduline-Tit sightings, Kidepo Valley National Park ranks 4th at under 5%. The best odds are in Awash National Park (Ethiopia, about 40%), Mkomazi National Park (Tanzania, about 10%) and Samburu National Reserve (Kenya, about 10%).
Same order: Passeriformes
The closest relatives of the Mouse-colored Penduline-Tit that you can see in Kidepo Valley National Park (order Passeriformes, Perching Birds) are Piapiac (about 70%), Red-cheeked Cordon-bleu (about 70%) and Yellow-billed Shrike (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mouse-colored Penduline-Tit is recorded against all the birds logged in Kidepo Valley National Park (10 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.
