Scavenging is a way of obtaining high quality food that would be difficult to access otherwise. When ravens scavenge, they have a high likelihood of encountering heterospecifics defending their food sources, for example wolves. Common ravens are a good system to study the behavior of scavengers when foraging in the presence of conspecifics and heterospecifics at the BugnyarLab at KLF Grünau. There, at the Cumberland gamepark, a large group of individually marked non-breeding ravens takes advantage of the resources of the park by scrounging the food of various zoo animals, like wolves and wild boars. In the upcoming 3 years the PhD candidate Silvia Damini will examine how ravens interact with conspecifics and heterospecifics on their feeding sites.
