The mountain thrush (Turdus plebejus) is species of bird in the family Turdidae, the thrushes and allies. It is found from Mexico to Panama. It was formerly known as the mountain robin and has also been called the American mountain thrush.
The mountain thrush was originally described in 1861 with its current binomial Turdus plebejus. The species' further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World assign it these three subspecies:
This article follows the three-subspecies model. The mountain thrush is 23 to 25.5 cm (9.1 to 10 in) long; males weigh an average of about 81 g (2.9 oz) and females average about 92 g (3.2 oz).

Rare
Under 5% of wildlife watchers report a Mountain Thrush sighting in El Triunfo on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 196th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Mountain Thrush in El Triunfo on a given day, against under 5% in May and July–March, 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 Mountain 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.
10th of 14
Of the 14 parks where we can rate Mountain Thrush sightings, El Triunfo ranks 10th at under 5%. The best odds are in Los Quetzales National Park (Costa Rica, about 60%), Volcán Barú National Park (Panama, about 50%) and Tapantí-Macizo de la Muerte National Park (Costa Rica, about 50%). All parks ranked.
Same genus: Turdus
The closest relatives of the Mountain Thrush that you can see in El Triunfo (genus Turdus, Typical Thrushes) are Clay-colored Thrush (about 80%), White-throated Thrush (about 30%) and Black Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mountain Thrush is recorded against all the birds logged in El Triunfo (10 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.
