Fork-tailed Flycatcher showing yellow crown stripe

This is another picture of the Fork-tailed Flycatcher in Stamford CT from my second visit to the Cove Island Park site. I particularly like this picture because of the yellow crown stripe - I think many Tyrant flycatchers have this sort of thing, including Eastern Kingbird and Couch's Kingbird from my personal experience - but like an Orange-crowned Warbler or Ruby-crowned Kinglet it's usually hidden. The FTFL was being harassed by Mockingbirds on this morning, and a couple of times had flared the yellow crown patch out of irritation, and in this photo it still shows partially (it's larger than this in display) even though it's not being chased by Mockingbirds right at this moment.
