Mockingbirds and Thrashers (Mimidae)
Curve-billed Thrasher (Toxostoma curvirostre) - HBW 10, p. 493
French: Moqueur à bec courbe
German: Krummschnabel-Spottdrossel
Spanish: Cuitlacoche Piquicurvo
Taxonomy: Orpheus curvirostris Swainson, 1827, Tableland of Mexico.
Perhaps most closely related to, and forming a superspecies with, T. ocellatum; both similarly close to the T. rufum superspecies. Races form two groups, E “nominate group” (also including celsum and oberholseri) and smaller and less distinctly marked taxa in W “palmeri group” (also including maculatum, occidentale and insularum); groups intergrade somewhat in SW USA (Arizona). Recent genetic studies suggest that the two groups may represent separate species. Several races (e.g. insulararum, celsum) poorly differenti.. View all taxonomy...
