Going counterclockwise along the trail that goes around the reservoir, after about 1.54 miles, there is a pine tree that is roughly double, maybe triple the height of the surrounding hedges (another landmark here is the boat that Hurricane Florence deposited in the canal/creek on the other side of the path. This pine tree is where I observed as a flock of at least 9 YEWA flew in to forage for invertebrate prey. The only thing I could definitively pick out as not being YEWA was a lone Northern Parula. The Yellow Warblers are as quick and agile as any warbler sp. I've attempted to photograph, and even with good light, make for challenging subjects.
