The clay-colored thrush (Turdus grayi) is a common Middle American bird of the thrush family (Turdidae). It is the national bird of Costa Rica, where it is well known as the yigüirro (Spanish: [ʝi'ɣwiro]). Other common names include clay-colored robin.
It ranges from South Texas (where it is rapidly expanding its range) to northern Colombia. West and north of the Isthmus of Tehuantepec, it is limited to the Atlantic slope, except for a population around Oaxaca City, Mexico that probably originates from escaped cage birds. In much of its range it is familiar in yards and gardens, similar to some other thrushes such as the American robin, the Eurasian blackbird, and the song thrush.
In general appearance and habits it resembles other Turdus thrushes such as the American robin. It is about the same length or slightly smaller: 23–27 cm (9.1–10.6 in), and weighs 74–76 g (2.6–2.7 oz) on average. The plumage is brownish, somewhat lighter below than above, lightest on the flanks. Birds from humid regions are darker than those from dry regions. The throat is faintly streaked. Immature birds have faint mottling on the back and underparts. The... Wikipedia →

Likely
About 40% of wildlife watchers report a Clay-colored Thrush sighting in Calakmul Biosphere Reserve on a given day, based on 369 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 60% of wildlife watchers report a Clay-colored Thrush in Calakmul Biosphere Reserve on a given day, against about 20% in June and October, the lowest months. That is one of Calakmul Biosphere Reserve's driest months, with about 30 mm of rain against 130 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Clay-colored 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.
29th of 53
Of the 53 parks where we can rate Clay-colored Thrush sightings, Calakmul Biosphere Reserve ranks 29th at about 40%. The best odds are in Masaya Volcano National Park (Nicaragua, about 90%), Poás Volcano National Park (Costa Rica, about 80%) and Cerro Azul Meámbar National Park (Honduras, about 80%). All parks ranked.
Same family: Turdidae
The closest relatives of the Clay-colored Thrush that you can see in Calakmul Biosphere Reserve (family Turdidae, Thrushes) are Wood Thrush (about 30%) and Swainson's Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Clay-colored Thrush is recorded against all the birds logged in Calakmul Biosphere Reserve (369 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.
