The dusky chlorospingus or dusky bush tanager (Chlorospingus semifuscus) is a species of bird in the family Passerellidae, the New World sparrows. It is found in Colombia and Ecuador. The dusky chlorospingus was formally described in 1873 with its current binomial Chlorospingus semifuscus. From that time and into the twenty-first century the Chlorospingus species were members of the family Thraupidae, the "true" tanagers, though their position within the family were uncertain. Based on studies published in 2002, 2003, and 2007, beginning in 2010 taxonomic systems transferred Chlorospingus to its present sparrow family. The Chlorospingus species were originally called "bush tanagers" or "bush-tanagers". Beginning in 2013 systems began changing the English name of the members of the genus to "chlorospingus" because they were no longer considered tanagers.
The dusky chlorospingus' further taxonomy is unsettled. Wikipedia →

Rare
Under 5% of wildlife watchers report a Dusky Bush-Tanager sighting in Los Nevados National Natural Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 376th most-seen of the 424 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dusky Bush-Tanager in Los Nevados National Natural Park on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Dusky Bush-Tanager sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Dusky Bush-Tanager sightings, Los Nevados National Natural Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Farallones de Cali National Natural Park (Colombia, under 5%).
GBIF citizen-science records
It is estimated from how often the Dusky Bush-Tanager is recorded against all the birds logged in Los Nevados National Natural Park (9 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.
