The ruddy-capped nightingale-thrush (Catharus frantzii) is a species of bird in the family Turdidae, the thrushes and allies. It is found from Mexico to Panama. The ruddy-capped nightingale-thrush was originally described by German ornithologist Jean Cabanis in 1861 with its current binomial Catharus frantzii. Its specific epithet commemorates the German naturalist Alexander von Frantzius. Its closest living relatives appear to be the North American species complex containing the veery (C. fuscescens) and the gray-cheeked thrush (C. minimus).
Though the ruddy-capped nightingale-thrush was described as a species, for much of the twentieth century it was treated as a subspecies of the russet nightingale-thrush (C. occidentalis). The two are sister species. The ruddy-capped nightingale-thrush's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World (HBW) assign it these eight subspecies: Wikipedia →

With luck
About 10% of wildlife watchers report a Ruddy-capped Nightingale-Thrush sighting in El Triunfo on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 135th 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 60%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Ruddy-capped Nightingale-Thrush in El Triunfo on a given day, against under 5% 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 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ruddy-capped Nightingale-Thrush 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 Ruddy-capped Nightingale-Thrush is recorded against all the birds logged in El Triunfo (29 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.
