The Birch Grove, the Old Field and the edge of the Ash Woods were the hotspots for warbler activity. I saw the following species, sometimes 3 or 4 or more of each, sometimes just a single bird: wilson's warbler, pine warbler, common yellowthroat, yellow-rumped warbler, magnolia warbler, palm warbler (in photo), black-throated green, nashville warbler and mourning warbler. There were others that I couldn't ID, they were flitting around high up in the treetops, and it was impossible to focus on them.
