Compared with Northern Saw-whet, Boreal Owls have white spots rather than streaks in the forehead, pale rather than dark bills, dark and white rather than tawny and white facial feathers, smaller eyes in a bulkier head, and white spotting on the chest rather than streaking like a Saw-whet. The topside was gray/brown with white spotting throughout the back. |
