Guide to Boreal Birds
Overview
This owl is most commonly seen late in the afternoon as it begins to move about in preparation for a night of hunting. It can often be identified at a great distance by its habit of hovering; its flight is erratic and bounding. Occasionally several birds may be seen at once, an indication that small rodents are especially numerous.
