Rufous-throated Solitaire
Myadestes genibarbis
The rufous-throated solitaire is 19 to 20.5 cm (7.5 to 8.1 in) long and weighs 24 to 30 g (0.85 to 1.1 oz). The sexes have the same plumage. Adults of the nominate subspecies M. g. genibarbis have a slate-gray crown, a white crescent below the eye, and a dark malar stripe on an otherwise orange-flecked face. Their upperparts are slate-gray. Their wings are slate-gray with black primary coverts, black bases on the secondaries, white bases on the inner primaries, and pale edges on the flight feathers. Their tail is mostly slate-gray with whitish outer feathers. Voice: The rufous-throated solitaire sings mostly at dawn, a "hauntingly beautiful minor key whistle". The song is a highly ventriloquial "first note low, second high, third low, interspersed with ringing double note". Its calls include a "single long toot" that sounds like a distant car horn.
