With luck
About 10% of wildlife watchers report a Marsh Tchagra sighting in Brazzaville on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 82 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.
March–May and July–December
In those months about 10% of wildlife watchers report a Marsh Tchagra in Brazzaville on a given day, against under 5% in January and February, the lowest months. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Marsh Tchagra sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brazzaville, in our data
Brazzaville is the only city on Wallace's Line with enough records to rate Marsh Tchagra sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Marsh Tchagra is recorded against all the birds logged in Brazzaville (7 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.
