Following studies published in the early 2000s that showed they were not close relatives, taxonomic systems separated them.
The Andean slaty thrush is monotypic. The Andean slaty thrush is 18 to 23.5 cm (7.1 to 9.3 in) long and weighs 50 to 67.5 g (1.8 to 2.4 oz). The species is sexually dimorphic.

Rare
Under 5% of wildlife watchers report an Andean Slaty Thrush sighting in Manu National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 566th most-seen of the 641 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Andean Slaty Thrush in Manu National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Andean Slaty 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 2 parks where we can rate Andean Slaty Thrush sightings, Manu National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Amboró National Park (Bolivia, under 5%).
Same genus: Turdus
The closest relatives of the Andean Slaty Thrush that you can see in Manu National Park (genus Turdus, Typical Thrushes) are Black-billed Thrush (about 30%) and Hauxwell's Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Andean Slaty Thrush is recorded against all the birds logged in Manu National Park (15 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.
