Abstract

Food habits of yellow armadillos have been reported to include mainly plant material and invertebrates. Although predation on medium vertebrates is unexpected, yellow armadillos present strategies to subjugate medium vertebrates. Here, we report events of predation upon domestic chickens by yellow armadillos in the Brazilian Pantanal. We installed 20 Tomahawk traps, each baited with one live chicken to capture felines and, throughout 15 days of trapping, we captured two yellow armadillos. Both killed the chickens and ate most of them. These events represent a new uppermost limit of prey size for yellow armadillos.

Keywords: armadillos; Dasypodidae; food habit; Pantanal; predation; xenarthrans
