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 Meru National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 231st most-seen of the 243 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Lanner Falcon in Meru National Park on a given day, against under 5% in June, September–October and December–April, the lowest months. That is one of Meru National Park's wettest months, with about 200 mm of rain against almost none in July. May and July–August have too few records to rate.
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.
11th of 32
Of the 32 parks where we can rate Lanner Falcon sightings, Meru National Park ranks 11th 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 Meru National Park (5 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.
