Under 5% of wildlife watchers report a Black-capped Sparrow sighting in Guayaquil on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 167 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-capped Sparrow in Guayaquil on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-capped Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Black-capped Sparrow is recorded against all the birds logged in Guayaquil (10 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.
