The common chlorospingus (Chlorospingus flavopectus), also referred to as common bush tanager, is a small passerine bird. It is a resident breeder in the highlands from central Mexico south to Bolivia and northwest Argentina. C. flavopectus in the loose sense is a notorious cryptic species complex, and several of the up to 25 subspecies recognized in recent times are likely to be distinct species. Some populations in fact appear to be more distinct than several other members of Chlorospingus.
The adult is 13.5 cm (5.3 in) long and weighs 20 g (0.71 oz) on average. They have a brown head with a (usually) thin supercilium and a white spot behind the eye and a light throat. The upperparts are olive and the underparts yellow, becoming white on the belly. Coloration, especially of the cheeks, throat and eye region, is very variable across the wide range, giving weight to the theory that these birds form a superspecies. Immatures are browner above, darker below, and have a duller olive eye spot. Hatchlings are covered in dark gray down feathers and have bright yellow bills.
The call is a squeaky tseeet or chit. Songs vary widely between the populations. The related... Wikipedia →

Possible
About 30% of wildlife watchers report a Common Chlorospingus sighting in El Triunfo on a given day, based on 79 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 221 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 60% of wildlife watchers report a Common Chlorospingus in El Triunfo on a given day, against about 10% in February and November, the lowest months. That is one of El Triunfo's driest months, with about 65 mm of rain against 420 mm in June. June has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Chlorospingus sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 22
Of the 22 parks where we can rate Common Chlorospingus sightings, El Triunfo ranks 6th at about 30%. The best odds are in Poás Volcano National Park (Costa Rica, about 60%), Monteverde Cloud Forest Reserve (Costa Rica, about 50%) and Volcán Barú National Park (Panama, about 40%). All parks ranked.
Same family: Passerellidae
The closest relatives of the Common Chlorospingus that you can see in El Triunfo (family Passerellidae, New World Sparrows) are White-eared Ground-Sparrow (about 30%), Rufous-collared Sparrow (about 30%) and White-faced Ground-Sparrow (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Chlorospingus is recorded against all the birds logged in El Triunfo (79 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.
