Introduction

The Slate-colored Solitaire is a relatively large-bodied member of the genus Myadestes, principally clad in gray and blackish, but easily identified by the broken white eye-ring, the buff patch in the wings, and the white-edged tail. Like all solitaires, the sexes are basically alike, and it is likely to be the song—which is especially haunting and ethereal-sounding in this species—which first draws attention to this bird. The Slate-colored Solitaire occurs from southern Mexico south to Nicaragua, and inhabits evergreen and cloud forests in the highlands of this region. It is generally still fairly common, despite the attentions of cagebird enthusiasts in some parts of the species’ range.

Field Identification

19–20·5 cm; 30–44 g. Plumage is dark slaty grey above, slightly paler below , with blacker primary coverts, buff-edged black flight-feathers, whitish-grey outer tail feathers, broken whitish eyering  ; bill dark; legs yellowish. Sexes similar. Juvenile is dark, with black-edged buff spots above, buffish moustachial streak, whitish-buff feather centres (scaly-looking) below.

Sister to M. occidentalis (which see). Proposed races pallens (Nicaragua) and veraepacis (highlands of Guatemala and N Honduras) appear indistinguishable in long series. Treated as monotypic.

Subspecies


SUBSPECIES

Myadestes unicolor unicolor Scientific name definitions

Distribution

Humid montane forests of s Mexico to Guatemala and n Honduras

SUBSPECIES

Myadestes unicolor pallens Scientific name definitions

Distribution

Humid montane forests of n-central Nicaragua

Distribution

S Mexico (from SE San Luis Potosí and Hidalgo) S to Guatemala, WC Belize, Honduras, N El Salvador and NW Nicaragua.

Habitat

Humid evergreen and Pinus-evergreen forest, and cloudforest-like (rich in lichens and bryophytes) habitat on ridges and associated ravines, at 780–2700 m. Replaces M. occidentalis in more humid conditions in Honduras.

Movement

Some post-breeding descent to near sea-level in S Veracruz (Sierra de los Tuxtlas), in Mexico, and in Belize; similarly, recorded in Feb–Mar at lower levels in El Salvador.

Diet and Foraging

No information.

Sounds and Vocal Behavior

Song ethereal, haunting, characteristic sound of local cloudforest; often starts hesitantly with a few poor notes, then breaks into varied series of clear or quavering fluty whistles, carefully delivered but of great beauty, often including or ending with loose trill, e.g. “weedu teee wheeoee du du whit whit whit… du-whip! Drrrreee teedle-o chup chup chup…”. Calls include hard nasal “rrank” or “rran” and buzzier “zzrink”.

Breeding

Apr in Mexico (Oaxaca). Nest typically made of moss, placed on ground amid forest debris on side of ravine. Eggs 2–3, whitish with reddish-brown markings. No other information.
Not globally threatened. Fairly common to common. Common resident of cloudforest throughout Honduras. Populations in E Mexico have been reduced, and possibly extirpated, owing to capture for the cagebird trade.

Abundance

Relative abundance is depicted for each season along a color gradient from a light color indicating lower relative abundance to a dark color indicating a higher relative abundance. Relative abundance is the estimated average count of individuals detected by an eBirder during a 1 hour, 1 kilometer traveling checklist at the optimal time of day for each species.   Learn more about this data
