Every winter along Boundary Bay the short-eared owls hunt along the grass on the foreshore. Sometimes they hunt along the King's Links golf course checking the rough for more than golf balls. These owls are called diurnal as they will hunt in the day. They will typically come out when there is a bit of cloud cover, Sometimes there are aerobatics when two owls or an owl and and a Northern Harrier get too close and one feels the other is poaching. I have never seen it end in a flurry of floating feathers, but it is still impressive none the less.
