Grey-cheeked Thrush (Catharus minimus) Science Article 2
Gray-cheeked Thrush and Bicknell’s Thrush were once considered to be conspecific (AOU 1957). Recently, they have been split into two distinct species (AOU 1998) – Bicknell’s Thrush (C. bicknelli), breeding in the Maritime provinces and New England, and Gray-cheeked Thrush, breeding in Newfoundland, the Labrador Peninsula, and west to Alaska (Ouellet 1993). Gray-cheeked Thrush is distinguishable from Bicknell’s Thrush by both morphometrics and song (Marshall 2001) and recent genetic analyses support the distinct species status of Bicknell’s Thrush (Outlaw et al. 2003, McEachen et al. 2004).
