Here are a couple shots of the Ash-throated Flycatcher in Lebanon Co. Behavior was very interesting, it foraged very low in the brush and grasses, often dropping down to catch something.
Below is the shot that can really clinch the id. The tail pattern on Ash-throated Flycatchers has a dark outer edge at the bottom of the outer tail feathers.
Below are some shots I had taken of the similar Great Crested Flycatcher.
