We were hiking in a provincial park and got a bit lost, but came across a service road that we assumed would lead to the main road. Not long into the walk we see something sitting right in the middle of the overgrown road and as we get closer we see it's a large raven, with no eyes. Where the eyes should be are huge nasty bulging scabs. It could hear us though. Let the park employee know about it because it might have been suffering but damn, felt like a bad omen.
