Rare
Under 5% of wildlife watchers report a Dull-colored Grassquit sighting in Amboró National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 221st most-seen of the 273 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.
September
In that month about 10% of wildlife watchers report a Dull-colored Grassquit in Amboró National Park on a given day, against under 5% in July–August and October–May, the lowest months. That is one of Amboró National Park's driest months, with about 90 mm of rain against 340 mm in January. June has too few records to rate.

GBIF citizen-science records
It is estimated from how often the Dull-colored Grassquit is recorded against all the birds logged in Amboró National Park (7 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.
