Some authors have treated it, the black-thighed grosbeak (P. tibialis), and the golden grosbeak (P. chrysogaster) as conspecific.
The yellow grosbeak is the largest member of its genus in Mexico and Central America. It is 21.5 to 24 cm (8.5 to 9.4 in) long; one female weighed 77.6 g (2.7 oz). Adult males of the nominate subspecies have a deep yellow head, nape, and breast. Their back and rump are a brighter yellow with some faint darker mottling. The sides of their mantle are black and their uppertail coverts black with wide white tips. Their wings are mostly black with wide white tips on the greater and median coverts, white bases on the primaries, and white... Wikipedia →

Possible
About 20% of wildlife watchers report a Yellow Grosbeak sighting in El Triunfo on a given day, based on 65 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 122nd most-seen of the 221 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 60% of wildlife watchers report a Yellow Grosbeak in El Triunfo on a given day, against under 5% in November and December, 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 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow Grosbeak sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Yellow Grosbeak sightings, El Triunfo has the highest daily chance: about 20%. Next come Cañón del Sumidero National Park (Mexico, about 10%) and Rocky Mountain National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Grosbeak is recorded against all the birds logged in El Triunfo (65 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.
