Rare
Under 5% of wildlife watchers report a Rusty Sparrow sighting in Lago de Yojoa on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 232nd most-seen of the 263 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.
June
In that month about 10% of wildlife watchers report a Rusty Sparrow in Lago de Yojoa on a given day, against under 5% in July to May, the lowest months. That is one of Lago de Yojoa's wettest months, with about 300 mm of rain against 65 mm in April.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Rusty 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 Rusty Sparrow is recorded against all the birds logged in Lago de Yojoa (16 verified sightings from 2019 to 2026), 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.
