Occurs as a quite common migrant in the wooded areas of the lab. In 1988, a pair established a territory and nested in the wooded strip of land between roads A1 and A2, just north of the administration building. (This is only the second nesting record for DuPage County). The female was observed feeding young on July 13th. The pair remained in the area through July. On June 22, 1988, a female was observed along the railroad tracks at the east edge of the site. It is possible that a pair nested in that area also. In 2009 a male and female were found in the small woodlot by the Education center. They were present there for several weeks and it is likely that they bred there, however we were unable to confirm that they did so,
