The Loggerhead Shrike breeds in semi-open areas in southern Ontario, Quebec and Alberta south to Mexico where it nests in dense trees and schrubs. It is also known as the 'Butcher Bird' as it impales its prey on thorns or barbed wire before eating it, because it lacks the talons of birds of prey. 'Loggerhead' refers to the relatively large head as compared to the rest of the body.
It looks much like a Northern Shrike, but the Loggerhead Shrike is smaller and its black mask extends across the forehead above the beak, which is usually not the case with the Northern Shrike. Finally, the beak of the Northern Shrike is longer than that of the Loggerhead.
Conservation
The Loggerhead Shrike is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
