Hello, this evening at 5:30 PM, while out for a run in my neighborhood  
of South Burlington, I heard 1 and possibly 2 Great Horned Owls  
calling in the woodlot on the east side of Ascension Lutheran Church,  
which is on the south side of  Allen Road.  There was the classic  
hooting call followed immediately by a series of softer hoots or  
"woofs".  At first I thought this was one bird giving an extended  
call, but then it occurred to me that it could be a male-female pair  
calling and responding.  No visual, hence no confirmation of more than  
one bird yet.
