With luck
About 10% of wildlife watchers report a Black-and-white Shrike-flycatcher sighting in Freetown on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 79 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Black-and-white Shrike-flycatcher in Freetown on a given day, against under 5% in February, the lowest month. That is one of Freetown's driest months, with almost no rain against 700 mm in August. March–April, July–August and October–November have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Black-and-white Shrike-flycatcher sightings with a recorded time, and about 8 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 Black-and-white Shrike-flycatcher is recorded against all the birds logged in Freetown (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.
