Setophaga nigrescens
Our only verified record is an adult male which visited a feeder in Georgetown, Brown County, from November 25, 1992 through February 16, 1993 (Pasquale 1993, including photograph; Brinkman 1993; accepted by OBRC Bartlett 1993).
There is also a fairly credible sight record, with good details, from April 28, 1973, in French Park (Brinkman 1993).
