Hauxwell's thrush (Turdus hauxwelli) is a species of bird in the family Turdidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and possibly Venezuela. Hauxwell's thrush was originally described in 1869 by George Newbold Lawrence with its current binomial Turdus hauxwelli. He wrote:
I have named this species in compliment to Mr. John Hauxwell, the well-known collector on the Upper Amazon and its tributaries. Since then it has had a complicated taxonomic history. 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 →

Rare
Under 5% of wildlife watchers report a Hauxwell's Thrush sighting in Yasuní National Park on a given day, based on 134 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 273rd most-seen of the 533 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.
September
In that month about 20% of wildlife watchers report a Hauxwell's Thrush in Yasuní National Park on a given day, against under 5% in November to August, the lowest months.
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.
3rd of 5
Of the 5 parks where we can rate Hauxwell's Thrush sightings, Yasuní National Park ranks 3rd at under 5%. The best odds are in Manu National Park (Peru, about 10%) and Tambopata National Reserve (Peru, about 10%).
Same genus: Turdus
The closest relatives of the Hauxwell's Thrush that you can see in Yasuní National Park (genus Turdus, Typical Thrushes) are 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 Yasuní National Park (134 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.
