Rare
Under 5% of wildlife watchers report a Crowned Slaty Flycatcher sighting in Asuncion on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 140th most-seen of the 224 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
October and November
In those months about 10% of wildlife watchers report a Crowned Slaty Flycatcher in Asuncion on a given day, against under 5% in December to September, the lowest months. Those are among Asuncion's wettest months, with about 180 mm of rain a month against 40 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Crowned Slaty Flycatcher sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 9
Of the 9 cities where we can rate Crowned Slaty Flycatcher sightings, Asuncion ranks 6th at under 5%. The best odds are in Santa Cruz de la Sierra (Bolivia, about 10%), Brasilia (Brazil, about 10%) and Cordoba (Argentina, about 10%).
GBIF citizen-science records
It is estimated from how often the Crowned Slaty Flycatcher is recorded against all the birds logged in Asuncion (35 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.
