Hi Folks, I was out of the country last month when the report of a raven heard in the Liberty Watershed came in, but I would like to add a few notes. There are only a few previous reports of ravens in Carroll County. All have come from the southeastern area, most in the vicinity of the North Branch of the Patapsco River which includes Liberty Lake. One was seen some years ago at Piney Run Park. So the possibility of one at Pine Knob Road is real. The nearest known breeding sites for ravens are at Sugarloaf in Frederick County and a new site in Pennsylvania about 10-15 miles north of the state line. As for the calls, once or twice annually I hear American Crows giving a very raven-like croak. Each time I try to locate the perpetrator to visually confirm my suspicion. Though the call is very similar it can be differentiated after hearing it a few times and recognizing it for what it is. I have observed American Crows giving this call in Allegany County as well as here. However, I have never suspected Fish Crows of this call. Consequently, I would be cautious about birds that were only heard. Keep reporting any interesting sounds. Maybe we can sort it out in time. Bob Bob Ringler Eldersburg MD ringler@cct.infi.net
