Northern Harriers hunt during the day. They are the most owl-like of all hawks in that they hunt by sight and by sound. Northern Harriers even look a bit like Short-eared Owls.
Northern Harriers share the same habitat with Short-eared Owls. Skirmishes over territory between the two species often occur late in the day as the Harriers are settling in for the night and the Shorties are stepping out to hunt.Great Marsh Sunset Rays
