Flycatchers in the genus Myiarchus are notoriously difficult to identify except by their vocalizations. Most sources emphasize subtle differences in the distribution of red in the tail, but this widespread species of Eastern North America is perhaps more readily identified by the pattern of white in the tertials (three elongated innermost secondaries). All three tertials are fringed with white on their outer webs, but the innermost (smallest) tertial has much more white, extending half way to the feather shaft and forming a conspicuous white wedge. I believe this pattern may be diagnostic for Great Crested Flycatcher and is visible in the lower photo.
Myiarchus flycatchers are unusual for their habit of nesting in tree cavities including old woodpecker holes, and for often incorporating a cast-off snakeskin in their nests.
