We've reach the point in the season (despite some unseasonal weather) where increased bird song and eagerness to see the season progress results in reports of heard-only birds that should not be in CT at this date. Some commonly mis-heard species include Willow Flycatcher (not expected until more than a week into May); Eastern Wood-Pewee (an even later arrival); and Yellow Warbler (usually late April). There are plenty of other candidates.
If anyone thinks they've heard one of these, make every effort to see the bird. Don't rely on what seems to be a "perfect" call or song. Starlings can and do make near-perfect Pewee whistles. Phoebes can produce Willow-like sounds. The highly variable songs of American Goldfinch can produce Yellow Warbler-like phrases (as well as a glimpse of a yellow bird). Of course N Mockingbirds can't be forgotten, and every year I hear some kind of Tufted Titmouse sound I'm sure I never heard before
A look at current maps in eBird shows that no Yellow Warblers have been reported to date north of northern Florida. Willow Flycatchers are even farther south.
