From Chris Elliot:
Hi Peter,
The park this morning was much quieter than Sunday, though I birded entirely north of Center Drive and the Pools. I wonder if many migrants left overnight. It took me half an hour to see my first migrants, and I had no yellow-rumps, yellows, or redstarts. The most active location was the north edge of the pools. CommonYellowthroat and BT Green Warbler were the most numerous warblers. I also had Palm, Black & White, Magnolia, and Blackburnian. Also good were Wood Thrush, Green Heron, Wood Duck, Sharp-shinned Hawk, and Kingfisher.
Here’s the Blackburnian from today, near the dog beach at the Upper Pool:
