Rare
Under 5% of wildlife watchers report a Marsh Tchagra sighting in Murchison Falls National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 351st most-seen of the 424 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Marsh Tchagra in Murchison Falls National Park 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 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.
3rd of 3
Of the 3 parks where we can rate Marsh Tchagra sightings, Murchison Falls National Park ranks 3rd at under 5%. The best odds are in Queen Elizabeth National Park (Uganda, about 10%) and Kibale National Park (Uganda, under 5%).

GBIF citizen-science records
It is estimated from how often the Marsh Tchagra is recorded against all the birds logged in Murchison Falls National Park (12 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.
