Shrikes (Laniidae)

Great Grey Shrike (Lanius excubitor) - HBW 13, p. 786

French: Pie-grièche grise German: Raubwürger Spanish: Alcaudón Norteño
Other common names: Grey Shrike; Northern Shrike (borealis, invictus); North Siberian Shrike (sibiricus); Steppe Shrike (homeyeri); Altai Shrike (mollis)

Taxonomy: Lanius excubitor Linnaeus, 1758, Europe = Sweden.
Forms a superspecies with L. ludovicianus, L. meridionalis and L. sphenocercus. Sometimes treated as conspecific with L. meridionalis, but the two overlap slightly in range, with little intergradation, in C Asia. Geographical variation complex and not fully understood, and obscured by individual variation and intergradation between races; in Nearctic, invictus apparently interbreeds with borealis in C Canada (NE Manitoba and N Ontario) and is sometimes synonymized with latter; sibiricus and mollis intergrade in NW Mongolia.
