Possible
About 20% of wildlife watchers report a Blue-black Grassquit sighting in Natal on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 30th most-seen of the 50 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March–May and July
In those months about 30% of wildlife watchers report a Blue-black Grassquit in Natal on a given day, against about 10% in October and November, the lowest months. Those are among Natal's wettest months, with about 160 mm of rain a month against 15 mm in November. January–February and June have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Blue-black Grassquit sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 35
Of the 35 cities where we can rate Blue-black Grassquit sightings, Natal ranks 5th at about 20%. The best odds are in San Pedro Sula (Honduras, about 30%), Lima (Peru, about 30%) and Goiânia (Brazil, about 30%).
Same family: Thraupidae
The closest relatives of the Blue-black Grassquit that you can see in Natal (family Thraupidae, Tanagers and Allies) are Bananaquit (about 70%), Palm Tanager (about 70%) and Sayaca Tanager (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue-black Grassquit is recorded against all the birds logged in Natal (15 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.
