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 →

Any time of year
In every month with enough records, under 5% of wildlife watchers report a Common Chlorospingus in San José on a given day, so our monthly data shows no clear season.
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.

GBIF citizen-science records
It is estimated from how often the Common Chlorospingus is recorded against all the birds logged in San José (45 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.
