A Raven in these parts would be a nice, although perhaps not unexpected, find since their range is expanding. However, I would be uncomfortable basing the identification on call alone. I heard a Raven a few years ago near Fort Smallwood park. I chased it, but all I ever saw was a flock of Fish Crows. A year or so later on the Bowie CBC, Bob Whitcomb came in at the end of the day and told me that he just had a similar experience. We have both heard many Ravens in several states. I asked around quite a bit about this at the time and was told (by a presumably reliable, but no longer remembered source) that Fish Crows do indeed have a call that can be mistaken for a Raven. Does anyone have any hard evidence to back up or contradict these two anecdotes? Dave David Mozurkewich Seabrook MD USA dm@fornax.usno.navy.mil
