Rare
Under 5% of wildlife watchers report a Sooty-fronted Spinetail sighting in Brasilia on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 104th most-seen of the 141 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.
November
In that month about 10% of wildlife watchers report a Sooty-fronted Spinetail in Brasilia on a given day, against under 5% in December to October, the lowest months. That is one of Brasilia's wettest months, with about 200 mm of rain against almost none in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Sooty-fronted Spinetail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 10
Of the 10 cities where we can rate Sooty-fronted Spinetail sightings, Brasilia ranks 8th at under 5%. The best odds are in Rosario (Argentina, about 40%), Buenos Aires (Argentina, about 30%) and Campo Grande (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Sooty-fronted Spinetail is recorded against all the birds logged in Brasilia (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.
