Abstract	Heterospecific competition for carrion may influence community structure as dominant species are predicted to exploit subordinate, social species to find food. We used camera traps and ungulate carcasses to assess scavenger interactions in central Oregon. Preliminary analyses indicate that raptor arrival at carcasses correlated with arrival of ravens (Corvus corax) and raptors usually arrived second; however, there was no difference in raptor and raven arrival time between closed and open carcasses. Ravens gained access to flesh after raptors perforated the hide and there were significant differences in feeding locations before and after raptor arrival. Our results indicate ravens could benefit from raptor arrival, although benefits may flow both directions. These data may suggest that one scavenging species uses another to locate a carcass.
