Great Gray Owls hunt at night and at dawn and dusk. The rest of the day they are comfortably out of sight in the forest. We had two opportunities to photograph a Great Gray Owl last week in Sax-Zim Bog, once in the low light of the morning and once in the low light of dusk. The sun was setting when the owl flew from a stump to the top of a spruce. While it clung to the boughs, it continually swiveled its head in search of prey.
