Habitat associations have primarily been studied up to the territory scale, with few studies assessing shrike habitat selection at landscape scales. The Loggerhead Shrike has a large range, estimated globally at 8,900,000 square kilometers. Grassland habitat loss and fragmentation is widely viewed as contributing to the decline.

Its range appears to be influenced by human-induced landscape changes. In Indiana, shrikes are most frequently found on traditional farms with livestock pasture and smaller fields with a variety of crops bordered by shrubby hedgerows and fence lines. They often nest in the vicinity of hedgerows or farm shelterbelts, utilizing dead treetop branches, utility wires or fences for hunting perches. Their breeding habitat is semi-open areas in southern Ontario, Quebec and Alberta, south to Mexico. Loggerhead shrike populations are extremely low, and no nests have been located in New York in recent years.
