I chased down the bird for about 45-minutes around the open fields south of the wet woods trying to get a positive ID. Kingbird was my call after a number of sightings and querying other birders, but it's true, Rueven, I wasn't completely sold myself. Still, I did try to rule out the other possibilities or I wouldn't have posted it. In the end, I'm happy to ere on the side of caution and hope someone else can either confirm or offer another possibility. I appreciate you keeping me on my game and questioning myself. Another forum member was shooting a lot pf photos much of the time I was out there today. Perhaps he can shed light on this with a pic.
