A male Northern Harrier (gray ghost) passed over the road just ahead of the car as I drove into HQ, but was too far away to anything but admire w/ the binoculars. The HQ and parking lot area was void of birds, so I headed over to Harbin Rd. to see if any shorebirds were still present. About 2-dozen Dunlin and 2-dozen Killdeer were out on the mudflats a 100 yds away. A single Pectoral Sandpiper was there, as well.
