English name: Loggerhead Shrike excubitorides subspecies
French name: Pie-grièche migratrice de la sous-espèce excubitorides
Scientific name: Lanius ludovicianus excubitorides (Swainson).
The Loggerhead Shrike excubitorides subspecies (hereafter Prairie Loggerhead Shrike) is a medium-sized songbird, approximately 21 cm in length. Adults are boldly coloured with a blend of black, white and gray, and are particularly conspicuous in flight. The best field mark is the black facial mask, which completely covers the eye (in the similar Northern Shrike, Lanius excubitor, the black facial mask does not extend above the eye). The bill is black with a hook at the tip of the upper mandible.
