Moved to the South Lookout at 9:30am EST. Light northerly winds with continuing drizzle and mist which gave way to fog. Visibility improved to overcast skies by the afternoon with some brighter periods and even a bit of blue sky from time to time. Raptor Observations: One Merlin rocketed through just above the ground at the North Lookout. A group off 44 Turkey Vultures pushed through the fog at the South Lookout early. The flight began to pick up in the afternoon as it cleared up with a steady flow of Turkey Vultures. A good day for harriers with 18. A dozen sharpies and two Coops. Thirteen red-tails. Just after 1pm EST the season's first SWAINSON'S HAWK (light morph) came through with a group of vultures. It circled in front then glided past a bit more inland. For falcons we had six kestrels and an additional Merlin. A Barred Owl was also heard calling from the South Lookout in the morning.
