The varied thrush (Ixoreus naevius) is a member of the thrush family, Turdidae. It is the only species in the monotypic genus Ixoreus. The varied thrush was formally described by the German naturalist Johann Friedrich Gmelin in 1789 under the binomial name Turdus naevius. Gmelin based his description of the "Spotted thrush" that had been described by John Latham in 1783 from specimens owned by Joseph Banks. These had been collected near Nootka Sound (formerly King George's Sound) which separates Nootka Island from Vancouver Island on the Pacific coast of Canada. The varied thrush is now the only species placed in the genus Ixoreus that was introduced by Charles Lucien Bonaparte in 1854. The genus name Ixoreus comes from the Ancient Greek ixos meaning "mistletoe". This was a synonym of a former name for the mockingbird genus, Mimus; Bonaparte assumed wrongly that, because William Swainson had shown a mockingbird and this thrush on the same plate of his book, they were related. The specific naevius is Latin for "spotted" from naevus meaning "spot".

With luck
About 10% of wildlife watchers report a Varied Thrush sighting in Kluane National Park on a given day, based on 68 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 129 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
September and October
In those months about 30% of wildlife watchers report a Varied Thrush in Kluane National Park on a given day, against under 5% in August and December–January, the lowest months. Those are among Kluane National Park's wettest months, with about 140 mm of rain a month against 45 mm in April.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Varied 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.
12th of 15
Of the 15 parks where we can rate Varied Thrush sightings, Kluane National Park ranks 12th at about 10%. The best odds are in Redwood National Park (United States, about 30%), Denali National Park (United States, about 30%) and Great Bear Rainforest (Canada, about 30%).
Same family: Turdidae
The closest relatives of the Varied Thrush that you can see in Kluane National Park (family Turdidae, Thrushes) are American Robin (about 50%), Swainson's Thrush (about 20%) and Hermit Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Varied Thrush is recorded against all the birds logged in Kluane National Park (68 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.
