Abstract

Loggerhead Shrikes (Lanius ludovicianus) have rarely been observed engaging in kleptoparasitism. We describe two observations of kleptoparasitism by Loggerhead Shrikes on soil-foraging songbirds. We suggest that kleptoparasitism of these birds gives shrikes access to resources that are otherwise unavailable. Kleptoparasitism may help to explain aggressive behavior by shrikes toward birds too large to be depredated successfully.
