The hermit thrush (Catharus guttatus) is a medium-sized North American thrush. It is not very closely related to the other North American migrant species of Catharus, but rather to the Mexican russet nightingale-thrush. The specific name guttatus is Latin for "spotted", though historically this species has been given 17 additional species or subspecies names by various authors, now all treated as synonyms.
This species measures 15 to 18 cm (5.9 to 7.1 in) in length, spans 25 to 30 cm (9.8 to 11.8 in) across the wings and weighs 18 to 37 g (0.63 to 1.31 oz). Among standard measurements, the wing chord is 7.8 to 11.1 cm (3.1 to 4.4 in), the bill is 1.6 to 1.9 cm (0.63 to 0.75 in) and the tarsus is 2.7 to 3.3 cm (1.1 to 1.3 in). It is more compact and stockier than other North American Catharus thrushes, with relatively longer wings. The hermit thrush has the white-dark-white underwing pattern characteristic of Catharus thrushes. Adults are mainly brown on the upperparts, with reddish tails. The underparts are white with dark spots on the breast and grey or brownish flanks. They have pink legs and a white eye ring. Birds in the east are more olive-brown... Wikipedia →

With luck
About 10% of wildlife watchers report a Hermit Thrush sighting in Isle Royale National Park on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 46th most-seen of the 105 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.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Hermit 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.
15th of 45
Of the 45 parks where we can rate Hermit Thrush sightings, Isle Royale National Park ranks 15th at about 10%. The best odds are in Guadalupe Mountains National Park (United States, about 40%), Kenai Fjords National Park (United States, about 40%) and Gros Morne National Park (Canada, about 40%).
Same genus: Catharus

GBIF citizen-science records
It is estimated from how often the Hermit Thrush is recorded against all the birds logged in Isle Royale National Park (44 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.
