Bone damage patterns found in the avian prey remains of crested caracara Caracara plancus (Aves, Falconiformes)

The following paper presents the results of the analysis of the avian prey bones found in uneaten remains of crested caracara (Caracara plancus, Aves, Falconiformes) from La Pampa province, Argentina. Anatomical parts representation and taphonomic modifications were evaluated and compared to results of the evaluation of bone remains recovered from crested caracara’s pellets and to previous studies of other diurnal birds of prey. The results suggest a preferential consumption of some body parts of avian prey, as evidenced in the high frequency of wing elements in the uneaten prey remains. This analysis helps to support interpretative data concerning the origins of avian remains in the zooarchaeological and paleontological record, and contributes to the knowledge of a common predator found throughout diverse environments in South America.

► The taphonomic analysis of avian prey remains of Caracara plancus (Aves, Falconiformes) is presented. ► This analysis helps to identify the characteristics of bones which have been digested or discarded. ► The results suggest a preferential consumption of some body parts of avian prey. ► There is a great amount of wing elements in the uneaten prey remains.
