The slate-colored solitaire (Myadestes unicolor) is a species of bird in the family Turdidae, the thrushes. It is found in Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. The slate-colored solitaire was originally described in 1857 as Myadestes unicolor and has retained that binomial since then. The slate-colored solitaire and the brown-backed solitaire (M. occidentalis) are sister species.
The slate-colored solitaire's further taxonomy is not settled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World treat it as monospecific. This article treats the slate-colored solitaire as monotypic.
The brown-backed solitaire is 19 to 20.5 cm (7.5 to 8.1 in) long and weighs 30 to 44 g (1.1 to 1.6 oz). The sexes have the same plumage. Adults are mostly slaty gray that is slightly lighter on their underparts than above. They have a broken white eye-ring, blacker primary coverts, black flight feathers with buff edges, and whitish gray outer tail feathers... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Slate-colored Solitaire is recorded against all the birds logged in Pico Bonito National Park (8 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.
