Cisticola bulliens
In 3 days ~10% in a week ~30%
The bubbling cisticola (Cisticola bulliens) is a species of bird in the family Cisticolidae. It is found in Angola and Democratic Republic of the Congo. Its natural habitats are dry savanna and subtropical or tropical dry lowland grassland.
The song of the bird is variable, but its typical pattern is a couple of "che" notes followed by a long, liquid trill; overall, the song is very similar to the songs of chattering and rattling cisticolas. The bird gives squeaky whistles and scolding calls. Wikipedia →

With luck
About 10% of wildlife watchers report a Bubbling Cisticola sighting in Luanda on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 45 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and July–August
In those months about 10% of wildlife watchers report a Bubbling Cisticola in Luanda on a given day, against under 5% in January, April and September–November, the lowest months. Those are among Luanda's driest months, with about 10 mm of rain a month against 80 mm in April. February–March, June and December have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Bubbling Cisticola sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Luanda, in our data
Luanda is the only city on Wallace's Line with enough records to rate Bubbling Cisticola sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the Bubbling Cisticola that you can see in Luanda (order Passeriformes, Perching Birds) are Pied Crow (about 50%), House Sparrow (about 40%) and Common Bulbul (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bubbling Cisticola is recorded against all the birds logged in Luanda (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.
