The pictures tell the story:
We found 35 casualties at the Noble Research Center in 2015, plus 11 trapped birds. From 2010–2015, the NRC has averaged 35.5 victims.
I conducted 10 scavenging trials in 2015, with an average carcass survival time of 10.40 days. We ran 265 surveys in 2015, which works out to a carcass search every 1.38 days.
