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 →

Rare
Under 5% of wildlife watchers report a Ruddy-capped Nightingale-Thrush sighting in Celaque National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 183rd most-seen of the 193 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and May
In those months about 10% of wildlife watchers report a Ruddy-capped Nightingale-Thrush in Celaque National Park on a given day, against under 5% in February–April and June–December, the lowest months.
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.
12th of 13
Of the 13 parks where we can rate Ruddy-capped Nightingale-Thrush sightings, Celaque National Park ranks 12th at under 5%. The best odds are in Los Quetzales National Park (Costa Rica, about 40%), Volcán Barú National Park (Panama, about 40%) and Irazú Volcano National Park (Costa Rica, about 20%).

GBIF citizen-science records
It is estimated from how often the Ruddy-capped Nightingale-Thrush is recorded against all the birds logged in Celaque National Park (6 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.
