Bicknell's Thrush (Catharus bicknelli) - HBW 10, p. 703
French: Grive de Bicknell
German: Bicknelldrossel
Spanish: Zorzalito de Bicknell
Taxonomy: Hylocichla aliciae bicknelli Ridgway, 1882, near the summit of Slide Mountain, Ulster County, New York, USA.
Formerly placed in Hylocichla, along with C. fuscescens, C. minimus, C. ustulatus and C. guttatus. Until recently treated as a race of C. minimus, and separation as a species still a matter of contention; vocal, morphological and even biochemical differences very subtle, and considered by some to have subspecific value only, but seemingly parapatric breeding and probably discrete winter distributions suggest species-level separation just tenable. Nonetheless, intermediates between the two taxa occur, and Newfoundland population of C. minimus ap.. View all taxonomy...
Formerly placed in Hylocichla, along with C. fuscescens, C. minimus, C. ustulatus and C. guttatus. Until recently treated as a race of C. minimus, and separation as a species still a matter of contention; vocal, morphological and even biochemical differences very subtle, and considered by some to have subspecific value only, but seemingly parapatric breeding and probably discrete winter distributions suggest species-level separation just tenable. Nonetheless, intermediates between the two taxa occur, and Newfoundland population of C. minimus approaches present species in size and coloration. Monotypic.
Distribution: E Canada and NE USA; non-breeding mainly Hispaniola, also E Cuba, Jamaica and Puerto Rico.
