Taxonomic Comments
This thrush formerly was placed in the genus Hylocichla (AOU 1983). Bicknell's Thrush (C. bicknelli) was formerly included as a subspecies of C. minimus; raised to full species status by Ouellet (1993) based on differences in morphology, bill and plumage color, vocalizations, and mtDNA. This change was accepted by AOU (1995).

Two subspecies are sometimes recognized: C. m. aliciae (Baird 1858) breeds from Alaska east to Labrador, south to northern Alberta; C. m. minimus (Lafresnaye 1848) breeds on Newfoundland and possibly northern Quebec (Lowther et al. 2001).

Rank Reasons
Widespread, numerous, secure.
Range Extent Comments
Breeding range extends from northeastern Siberia and northern Alaska across northern Canada to Labrador and Newfoundland, south to southern Alaska, northwestern British Columbia, southern Mackenzie, northern Alberta (probably), northeastern Saskatchewan, northern Manitoba, extreme northern Ontario, south-central Quebec, and St. Pierre et Miquelon (Ouellet 1993, AOU 1995). During the northern winter, the species occurs mostly in northern South America: Guyana, Venezuela, Colombia, eastern Ecuador, eastern Peru, and western Amazonian Brazil; perhaps mainly in southern Venezuela and western Amazon basin; Trinidad; rarely north to Panama, casually north to Costa Rica (Ouellet 1993, AOU 1995).
Threat Impact Comments
No major threats are known. Species is more likely affected by habitat alteration during nonbreeding season.
Ecology & Habitat

Description

Medium-sized thrush, slightly larger than other Catharus thrushes (Lowther et al. 2001). Rather plain, cold-grayish face with indistinct whitish streaks or mottling on ear coverlets. Gray cheek patch is most distinctive trait; gray brown above with a faint and incomplete eye ring. Underparts stark white except where dark brown spots speckle the pale, slightly buffy breast and the flanks and tail are brownish gray (Lowther et al. 2001).

Habitat

Coniferous forest (mainly spruce), tall shrubby areas in taiga, willow and alder thickets near water or above tree line (Ouellet 1993); in migration and winter also in deciduous forest, forest borders, open woodland, second growth, and scrub. Nests from ground level to about 6 m up, in willow, alder, or spruce (Terres 1980).

Ecology

The only neotropical migrant whose breeding distribution includes northeastern Siberia. Least known of Catharus thrushes due to remote breeding range (Lowther et al. 2001). Shows considerable geographic overlap with four other thrushes, including two congeners, Swainson's Thrush (C. ustulatus) and Hermit Thrush (C. guttatus) (Lowther et al. 2001).

Reproduction

Eggs are laid in June (mostly) and July. Clutch size is 3-6 (usually 4). Incubation, by female, lasts 12-14 days. Young are tended by both parents, leave nest at 11-13 days.
