Constructs bulky, cup- shaped nest in shrub. A study in southeastern Idaho located nests in sagebrush, bitterbrush, and greasewood. Most nests were in sagebrush, and a lower than expected nest height was observed in all shrub species. Species hunts from perch, or catches prey in mid-air. Territorial throughout year. Size of territory may be about 6 ha in grassy hills; 10-16 ha in semi-desert. May maintain separate breeding and winter territories. Idaho study indicated that shrikes directly lowered nesting success of Sage and Brewer's Sparrows and Sage Thrashers. Loggerheads are one of 3 shrub-steppe neotropical migrants declining in Idaho. Shrike species throughout world are thought to be declining.
