This shy, reclusive, and difficult to detect circumpolar owl has been recorded several dozen times in Massachusetts, most often during irruption years. The most recent invasion was during the winter of 1991/1992 with six statewide records.
Boreal Owls can be confused with Northern Saw-whet Owls with poor views. However, Boreal Owls always show a dark “V” that connects the head to the eyes. Boreal Owls also show a spotted forehead and crown; the Saw-whet shows streaking in this area.
