During the twentieth century it has been considered by different authors to be a subspecies of the cocoa thrush (T. fumigatus) or the pale-vented thrush (T. obsoletus). By late in the century it had regained its status as a full species. Genetic data published in the early 2000s show that Hauxwell's thrush and the cocoa thrush are sister species and that the pale-vented thrush is not closely related to either of them.
Hauxwell's thrush is monotypic. Hauxwell's thrush is 20 to 23 cm (7.9 to 9.1 in) long and weighs about 69 g (2.4 oz). The sexes have the same plumage. Adults have a rufous-brown head with a dark-streaked whitish throat. Their upperparts, wings, and tail... Wikipedia →

With luck
About 10% of wildlife watchers report a Hauxwell's Thrush sighting in Tambopata National Reserve on a given day, based on 246 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 174th most-seen of the 550 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Hauxwell's Thrush in Tambopata National Reserve on a given day, against under 5% in March–June and September, the lowest months. That is one of Tambopata National Reserve's wettest months, with about 400 mm of rain against 45 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Hauxwell's Thrush sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 parks where we can rate Hauxwell's Thrush sightings, Tambopata National Reserve ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Manu National Park (Peru, about 10%).
Same genus: Turdus
The closest relatives of the Hauxwell's Thrush that you can see in Tambopata National Reserve (genus Turdus, Typical Thrushes) are White-necked Thrush (about 10%), Black-billed Thrush (about 10%) and Lawrence's Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hauxwell's Thrush is recorded against all the birds logged in Tambopata National Reserve (246 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.
