Effraie des clochers, pop. de l'Est— Quebec wildlife

The Barn Owl, or Tyto alba, is a medium-sized nocturnal bird, measuring approximately 33 to 39 cm in length and weighing between 250 and 600 grams. Its plumage is particularly distinctive, featuring a heart-shaped white face, a brown and mottled black back, and broad wings that allow it to glide silently. Unlike other owl species, there is no pronounced sexual dimorphism, although females are generally slightly larger than males. Its characteristic call, a soft and plaintive hoot, is often heard on clear nights, adding a mysterious ambiance to the nocturnal landscape.

In Quebec, the Barn Owl is primarily found in agricultural regions and open habitats, such as grasslands, fields, and urban areas. It is often seen near barns, silos, or old buildings, which provide nesting and resting sites. The Montérégie and Laurentians regions are particularly conducive to its presence. Although it can be found in several areas, its habitat is sometimes fragmented, which can impact its distribution.

Behaviorally, the Barn Owl is primarily nocturnal. The breeding season typically begins in spring, with nesting occurring in crevices, attics, or cavities. A female can lay between 2 to 18 eggs, with incubation lasting about 30 to 34 days. The young leave the nest after approximately 8 to 10 weeks but remain dependent on their parents for some time before establishing themselves independently.

Its ecological role is crucial, as it helps regulate rodent populations, which aids in maintaining the balance of agricultural ecosystems. To observe this species, it is recommended to visit rural areas or grasslands during the night, paying attention to its silent flight and calls. Visits to nesting sites and old barns may also provide opportunities for observation.
