Are ravens in Oklahoma?

Scientific data on the subject can be a bit flaky for the state of Oklahoma, some saying they don't occur anywhere in the state, while other sources say they occure in the pan handle of Oklahoma. Such things as birds ranges and habitats can be hard to keep track of, but with ravens preferring more hill and mountainous areas with cliffs for nesting, most of Oklahoma is left out of that bill. However, on rare occasions one of these birds can be spotted far from its range meandering parts of Oklahoma, though its more likely to be a common crow.
