Their vocal range is broad and varied, and has been described as harsh and jarring.<ref>{{cite journal | last1 = Frost | first1 = E | year = 1885 | title = The loggerhead shrike in New Hampshire | journal = The Auk | volume = 2 | issue = 4| page = 379 | doi=10.2307/4625312| jstor = 4625312 }}</ref> The shrike's notes include squeaky whistles, shrill trills, and guttural warbles.<ref name="chapman1904"/> The trills sung by males during breeding season vary in rhythm and pitch. When alarmed, a shrike will produce a "schgra-a-a" shriek while spreading out its tail feathers. A distinctive alarm call is often given when threats from above are detected. Nestlings will make "tcheek" and "tsp" sounds shortly after hatching.<ref name="soendjoto1995">{{cite book| last= Soendjoto |first= M.| year= 1995| title= Vocalization behavior of captive loggerhead shrikes (Lanius ludovicianus excubitorides)| place= Montreal | publisher= McGill University Libraries}}</ref> During courtship feedings, females may ask for food with "mak" begging notes; conversely, males emit "wuut" or "shack" sounds to offer food.<ref>{{cite journal | last1 = Cade | first1 = T | year = 1992 | title = Hand-reared loggerhead shrikes breed in captivity | journal = Condor | volume = 94 | issue = 4| pages = 1027–1029 | doi=10.2307/1369306| jstor = 1369306 }}</ref> The male emits a territorial, harsh shriek, while the female's song is pitched lower and softer than the male's.
