The plumbeous-backed thrush (Turdus reevei) is a species of bird in the family Turdidae. It is found in Ecuador and Peru. The plumbeous-backed thrush was originally described by George Newbold Lawrence in 1869 with its current binomial Turdus reevei. Lawrence chose the specific epithet reevei to honor J. F. Reeve, who collected the species' type specimen.
The plumbeous-backed thrush is monotypic. The plumbeous-backed thrush is 23 to 24 cm (9.1 to 9.4 in) long and weighs 61 to 66 g (2.2 to 2.3 oz). The sexes have almost the same plumage. Adult males have a mostly bluish slate-gray head with a dark-streaked white throat. Female's heads are slightly browner. Both sexes have bluish slate-gray upperparts, wings, and tail. They have a white crescent below the streaked throat, a pale gray breast that becomes white on the belly and vent, and an orange-buff wash on the flanks. Both sexes have a white to bluish white iris, a pale yellow bill, and pale yellow legs and feet. Juveniles are similar to adults but browner with buff spots and streaks on the upperparts and dark scallops in the underparts.

With luck
About 10% of wildlife watchers report a Plumbeous-backed Thrush sighting in Machalilla National Park on a given day, based on 108 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 70th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March and December
In those months about 30% of wildlife watchers report a Plumbeous-backed Thrush in Machalilla National Park on a given day, against under 5% in July and September, the lowest months. Those are among Machalilla National Park's wettest months, with about 80 mm of rain a month against 5 mm in September.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Plumbeous-backed 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.
Only Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate Plumbeous-backed Thrush sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Plumbeous-backed Thrush is recorded against all the birds logged in Machalilla National Park (108 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.
