Evidencia de cleptoparasitismo del caracara común (Caracara cheriway) sobre el alcaudón verdugo (Lanius ludovicianus)

Abstract

Kleptoparasitism of Crested caracara on Loggerhead shrike was recorded on July 18, 2013 in a fragmented habitat of desert Baja California Sur. An adult caracara kleptoparasitized a mammal prey (Peromyscus eva) that a loggerhead shrike had impaled in a shrub, an Adam´s tree. This is the first record of kleptoparasitism of a 1050-1300 g raptor on a small passerine bird (45 g).
