What is now the independent South American Classification Committee (SACC) had done so by 2007. By 2018 the IOC had adopted the split and the Clements taxonomy followed in 2025.

With luck
About 10% of wildlife watchers report a White-throated Thrush sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 68th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a White-throated Thrush in Reserva de la Biosfera Mariposa Monarca on a given day, against under 5% in October and December–February, the lowest months. April and June–September have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-throated 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.
7th of 24
Of the 24 parks where we can rate White-throated Thrush sightings, Reserva de la Biosfera Mariposa Monarca ranks 7th at about 10%. The best odds are in Coiba National Park (Panama, about 50%), Monteverde Cloud Forest Reserve (Costa Rica, about 30%) and El Triunfo (Mexico, about 30%). All parks ranked.
Same genus: Turdus
The closest relatives of the White-throated Thrush that you can see in Reserva de la Biosfera Mariposa Monarca (genus Turdus, Typical Thrushes) are American Robin (about 50%) and Rufous-backed Robin (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-throated Thrush is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (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.
