Types of Owls in Ontario: A Comprehensive Guide

Ontario, Canada's most populous province, is home to a fascinating array of wildlife, including several distinct species of owls. These creatures of the night captivate us with their silent flight and haunting calls. Let's delve into the diverse world of Ontario's owls, exploring their unique features, habitats, and habits.

Ontario's owls can be broadly categorized into two groups based on their size and appearance: typical owls and barn owls. Each of these groups houses captivating species, each with its unique tale to tell.

Typical Owls of Ontario

Typical owls, as the name suggests, exhibit characteristics commonly associated with owls, such as round heads, forward-facing eyes, and soft plumage for silent flight. Ontario plays host to several typical owl species, each with its unique characteristics.

These owls can be further divided into three groups based on their size: small, medium, and large typical owls.

Small Typical Owls

The northern saw-whet owl (Aegolius acadicus) is among the tiniest of Ontario's owls, with adults barely reaching a foot in length. They are characterized by their round, fluffy appearance and the distinctive white 'moustache' pattern on their facial disk, which helps direct sound toward their large, forward-facing ears.

These tiny owls are adaptable and can be found in both forested and urban environments. Their call, a shrill, descending series of notes, is often heard during the night, adding a touch of mystery to Ontario's winter nights.

Medium Typical Owls

.media The barred owl (Strix varia) is a striking medium-sized owl, notable for its thick, stocky body and distinctive 'Who-cooks-for-you, who-cooks-for-me' call. Their plumage is primarily a rich mottled brown, with buff streakings and barring that give them their name.

Barred owls favor mature forests, particularly those near bodies of water. They are known for their aggressive territorial defense and can often be heard vocalizing throughout the night, their calls echoing through the woods in a haunting cadenza.

Barn Owls of Ontario

The other major group of Ontario's owls, barn owls have a distinct appearance, with a heart-shaped facial disk, long, slender wings, and a white, grey, or buff plumage. These owls are also known as ' hGhost owls' due to their slow, silent flight and pale, mysterious appearance in the moonlight.

Our attention now turns to the two primary barn owl species found in Ontario.

Eastern Barn Owl

The eastern barn owl (Tyto alba pratincola) is the more common of the two barn owls in Ontario. As the name suggests, they prefer open habitats like fields, marshes, and farmland, and often nest in barns, abandoned buildings, or even in cavities in trees.

Eastern barn owls are specialized hunters, strictly feeding on small mammals. Their remarkable hearing allows them to detect the sounds of rodents moving beneath deep snow, enabling them to forage effectively year-round.

Western Barn Owl

The western barn owl (Tyto MHC) is less common and more migratory than its eastern cousin. They prefer drier, more open habitats, such as grasslands and agricultural fields. Unlike eastern barn owls, they typically avoid nesting in barns, opting for cavities in trees or cliff ledges.

Western barn owls differ from eastern barn owls in their plumage, which is primarily whitish or buff, with a distinctive dark heart-shaped facial disk. They also have a slower, more erratic flight than their eastern counterparts.

From the tiny northern saw-whet to the striking barred owl, Ontario's owls are as diverse as they are captivating. Each species plays a unique role in the province's ecosystem, their silent flight and haunting calls reminding us of the intricate web of life of which we are a part. Whether you're a seasoned birder or a curious newcomer, there's always more to discover and appreciate in the fascinating world of Ontario's owls.
