The mosque swallow (Cecropis senegalensis) is a large species of swallow. It is a resident breeder in much of sub-Saharan Africa, although most common in the west. It does not migrate but follows the rains to some extent.
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the mosque swallow in his Ornithologie based on a specimen collected in Senegal. He used the French name L'hirondelle du Sénégal and the Latin Hirundo Senegalensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. In 1766, when Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the mosque swallow. Linnaeus included a brief description and used Brisson's Latin name for his binomial name Hirundo senegalensis.
Formerly placed in the genus Hirundo the mosque swallow and its relatives have been shown by molecular studies to be a separate clade and are now placed in the genus Cecropis, which was introduced by the German zoologist Friedrich Boie in 1826.

With luck
About 10% of wildlife watchers report a Mosque Swallow sighting in Queen Elizabeth National Park on a given day, based on 122 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 176th most-seen of the 434 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Mosque Swallow in Queen Elizabeth National Park on a given day, against under 5% in January–February, April and August–October, the lowest months. That is one of Queen Elizabeth National Park's driest months, with about 35 mm of rain against 150 mm in April.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Mosque Swallow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 31
Of the 31 parks where we can rate Mosque Swallow sightings, Queen Elizabeth National Park ranks 15th at about 10%. The best odds are in Gonarezhou National Park (Zimbabwe, about 30%), Aberdare National Park (Kenya, about 20%) and Mana Pools National Park (Zimbabwe, about 20%).
GBIF citizen-science records
It is estimated from how often the Mosque Swallow is recorded against all the birds logged in Queen Elizabeth National Park (122 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.
