I hadn't planned on going up on the parkway this morning, but I saw that a female Blackpoll Warbler was seen (with photos) at the Humpback Rocks Visitor Center (mm. 5) yesterday morning. This must be a late migrant, as this species has usually moved through the area by now, and I haven't seen one so far in 2019. I almost always skip birding at the visitor center because there is a lot people and commotion there. I assumed that this warbler may have been moving north, so I got onto the parkway at the start, and then exited near mm. 2, and took parallel Route 610 that had much less traffic. Near mm. 3, I stopped when I thought that I heard a Blackpoll, so I birded there for about 30 minutes. I saw six avian species there, but no Blackpolls. There were a few American Redstarts, and at least two Worm-eating Warblers, one of which looked like a first year bird.

I got back onto the parkway near mm. 4, and stopped at the visitor center. It was jammed with cars, tour vans, and people. No birds there. So I continued on to the cirque (mm. 7.5) and Hickory Springs Overlook (mm. 12). There were Cerulean Warblers, Hooded Warblers, and more American Redstarts.

I reversed my route, and saw two more Hooded Warblers on Route 610, as well as a buck.

I ended the outing with 23 avian species, but no Blackpolls.
