Wanderlust World Wanderlust World Southwestern Ontario's mix of Carolinian forests, wetlands, farmland, and urban green spaces creates prime habitat for a remarkable diversity of owls. Here are the five species you're most likely to encounter:
North America's smallest owl (robin-sized), this master of camouflage comes in gray and rufous morphs. Despite the name, its call is a haunting, descending whinny or a monotone trill—not a screech. Thrives in woodlots, parks, and suburban yards with mature trees. Cavity nester; readily uses nest boxes.
The quintessential "hoot owl" and a formidable apex predator. Large, with prominent ear tufts, yellow eyes, and a deep, resonant "hoo-hoo-hoo-hoo." Takes prey up to skunk and rabbit size. Nests early (January–February), often appropriating hawk or crow nests. Ubiquitous across habitats.
Medium-sized, dark-eyed, and beautifully barred brown-and-white. The classic "who-cooks-for-you, who-cooks-for-you-all" call echoes through mature deciduous forests near water. Expanding range westward. More vocal by day than other owls.
Slender, cryptic, with extraordinarily long ear tufts set close together. Prefers dense coniferous or mixed woods near open hunting grounds. Communal winter roosts (sometimes dozens together). Soft, low hoots; eerie, cat-like screams. Uncommon and declining.
Open-country specialist: grasslands, marshes, fallow fields. Often hunts at dusk/dawn with buoyant, moth-like flight. Short, barely visible ear tufts. Barking "wak-wak-wak" calls. Nests on ground. Winter visitor to SW Ontario; breeds farther north.
Go at dusk or dawn. Listen first. Use playback sparingly and ethically. Respect nesting sites. Report sightings to eBird or local naturalist groups. Many populations face habitat loss—your observations aid conservation.
