The lanner falcon (Falco biarmicus) is a medium-sized bird of prey that breeds in Africa, southeast Europe and just into Asia.

Most likely either the lanner or peregrine falcon was the sacred species of falcon to the ancient Egyptians, and some ancient Egyptian deities, like Ra and Horus, were often represented as a man with the head of a lanner falcon.
The lanner falcon was described by the Dutch zoologist Coenraad Jacob Temminck in 1825 under the current binomial name Falco biarmicus. The type locality is Caffraria and the Cape of Good Hope. Falco is Late Latin for a "falcon", from falx, falcis "sickle". The Swedish naturalist Carl Linnaeus had used the specific epithet biarmicus for the bearded reedling and Temminck clearly believed that the word meant "bearded" but it is likely that Linnaeus was using the Latinized form for Bjarmaland, a district in northern Russia.

Rare
Under 5% of wildlife watchers report a Lanner Falcon sighting in Nairobi National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 264th most-seen of the 371 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.
June
In that month about 10% of wildlife watchers report a Lanner Falcon in Nairobi National Park on a given day, against under 5% in July to May, the lowest months. That is one of Nairobi National Park's driest months, with about 35 mm of rain against 180 mm in April.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lanner Falcon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 32
Of the 32 parks where we can rate Lanner Falcon sightings, Nairobi National Park ranks 17th at under 5%. The best odds are in Kgalagadi Transfrontier Park (South Africa, about 50%), Bale Mountains National Park (Ethiopia, about 40%) and Etosha National Park (Namibia, about 10%).
GBIF citizen-science records
It is estimated from how often the Lanner Falcon is recorded against all the birds logged in Nairobi National Park (46 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.
