Rare
Under 5% of wildlife watchers report a Lanner Falcon sighting in Cape Town on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 194th most-seen of the 196 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lanner Falcon in Cape Town on a given day, so our monthly data shows no clear season.
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.

GBIF citizen-science records
It is estimated from how often the Lanner Falcon is recorded against all the birds logged in Cape Town (9 verified sightings), 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.
