Loggerhead shrikes are monogamous birds. However, males are known to begin second nesting attempts with a second female before his first clutch has fledged. They begin breeding during their first spring.<ref name="chabot1994"/> During this time, the male performs a [[courtship ritual]] that occurs in flight. He dances erratically in the air, flying rapidly up and down and occasionally chasing the female. He presents himself to his potential mate by fanning out his tail and fluttering his wings.<ref name="smith1973"/><ref name="miller1931"/><ref>{{cite book| last= Bent | first= A.| year= 1950| chapter= Loggerhead shrike| title= Life histories of North American wagtails, shrikes, vireos and their allies| place= New York | publisher= Dover Publications, Inc.| isbn= }}</ref>  Females may respond to the fluttering display with begging notes, similar to those of juveniles begging for food; this encourages the male to feed her.<ref name="smith1973"/>

The bird breeds in semi-open areas in [[southern Ontario]], [[Quebec]], and the Canadian prairie provinces, south to [[Mexico]]. It nests in isolated or small clusters of dense trees and shrubs from near ground level to over 4m in height. There is an increase in average [[avian clutch size|clutch size]] as latitude increases. Shrikes begin incubation after laying the second to last egg, resulting in asynchronous hatching. Incubation, on average, lasts 16 days. The female lays 4 to 8 eggs in a bulky cup made of twigs and grass. Once hatched, nestlings are fed by both the male and female parent. Average fledging period is about 19 days. Young may then remain nearby and dependent on adults for 3 to 4 weeks. After that, they begin to forage independently. Oftentimes, nestlings do not survive long past hatching. In the case of dead nestlings, adult shrikes may eat or discard their bodies or else feed them to their remaining young.<ref>{{cite journal| last= Kridelbaugh |first= A.| year= 1983| title= Nesting ecology of the loggerhead shrike in central Missouri| journal= The Wilson Bulletin| volume= 95| number= 2| pages= 303–08}}</ref> The oldest recorded age of a loggerhead shrike was 12 years and 6 months.<ref>{{cite book| editor-last1= Podulka | editor-first1= S| editor-last2= Rohrbaugh | editor-first2= R| editor-last3= Bonney | editor-first3= R| year= 2004| title= Handbook of Bird Biology| place= Princeton, New Jersey| publisher= Cornell Lab of Ornithology| edition= | isbn= }}</ref>
