American Restart warblers, foraging quickly in Lamar Woods

I ran into local birder Jill White Smith who had found an American Redstart in Lamar Woods earlier this morning. I was able to refind it as well as a second American Redstart foraging nearby. These two were very active, flitting about constantly and quickly higher in the canopy. I think these are adult females because they have the 'yellow base of remiges' noted in The Sibley Guide to Birds. SeEtta
