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. Adult males have a mostly slate-gray head with a pale eye-ring and a dark-streaked white throat. Their upperparts, wings, and tail are slate-gray.

Rare
Under 5% of wildlife watchers report an Andean Slaty Thrush sighting in Amboró National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 134th most-seen of the 273 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.
May, July and September
In those months about 10% of wildlife watchers report an Andean Slaty Thrush in Amboró National Park on a given day, against under 5% in August and October–April, the lowest months. 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 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.
Yes
Of the 2 parks where we can rate Andean Slaty Thrush sightings, Amboró National Park has the highest daily chance: under 5%. Next come Manu National Park (Peru, under 5%).
Same genus: Turdus
The closest relatives of the Andean Slaty Thrush that you can see in Amboró National Park (genus Turdus, Typical Thrushes) are Rufous-bellied Thrush (about 50%), White-necked Thrush (about 40%) and Creamy-bellied Thrush (about 20%), 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 Amboró National Park (20 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.
