Amid the heavy snowfall in Nova Scotia this winter, the province’s smallest owls are being forced to venture into more human-inhabited regions in search of food. The Northern saw-whet owl, smaller than a robin, is struggling to hunt its usual diet of mice, voles, and shrews due to the snow cover, according to Randy Lauff, a biology instructor at St. Francis Xavier University specializing in boreal and Northern saw-whet owls.
Lauff explains that owls, known for their sharp eyesight and exceptional hearing, possess unique predatory skills. While larger owls can detect rodents beneath thick snow layers and use their size to capture prey with precision, the tiny saw-whet owls face challenges due to their petite stature.
The scarcity of food sources has led to an increase in saw-whet owl sightings in rural and urban areas with bird feeders this winter. These owls are not drawn to the seeds but to the small creatures attracted to the feeders, such as mice and small birds.
Although Nova Scotia may seem to have experienced more prolonged and deeper snow accumulation this season, meteorologist Ryan Snoddon from CBC notes that the winter conditions are relatively typical, with a recent spike in snowfall.
Notably, Hatfield Farm in Hammonds Plains, N.S., recently encountered a saw-whet owl on its premises for the first time. The owl sought shelter in one of the barns, perching in the rafters before moving on in search of prey.
Cherie Hatfield, the farm owner, speculates that the owl was hunting for small animals around the barn due to the snowy conditions. She emphasizes the challenges predators face during harsh winters as they strive to survive.
Lauff advises residents who spot saw-whet owls in their yards to give the birds space and avoid causing them stress. Disturbing these owls can interfere with their hunting abilities and overall well-being.
Snow cover presents both advantages and disadvantages for birds of prey, as explained by Hope Swinemar, founder of Hope for Wildlife in Seaforth, N.S. While the contrasting colors make prey more visible against the snow, icy crusts can hinder hunting efforts, potentially leading to increased starvation among the wildlife.
Swinemar mentions a rise in the number of barred owls needing assistance at the wildlife center, likely due to collisions with vehicles while hunting along roads at dusk. Despite the challenges posed by severe winters, Swinemar acknowledges the resilience of wildlife in adapting to adverse weather conditions.
In conclusion, the wildlife experts emphasize the importance of respecting and protecting these creatures during the winter season, highlighting the significance of minimizing disturbances to support their survival efforts.
