Rare
Under 5% of wildlife watchers report a Brown Woodland-Warbler sighting in Addis Ababa on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 101st most-seen of the 109 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Brown Woodland-Warbler in Addis Ababa on a given day, against under 5% in September to July, the lowest months. That is one of Addis Ababa's wettest months, with about 250 mm of rain against 10 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Brown Woodland-Warbler 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 Addis Ababa, in our data
Addis Ababa is the only city on Wallace's Line with enough records to rate Brown Woodland-Warbler sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Phylloscopus

GBIF citizen-science records
It is estimated from how often the Brown Woodland-Warbler is recorded against all the birds logged in Addis Ababa (5 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.
