In Nova Scotia, the recent heavy snowfall has forced small owls to venture closer to human settlements in search of food. The Northern saw-whet owl, smaller than a robin, typically preys on mice, voles, and shrews but has struggled due to the snow cover, as explained by Randy Lauff, a biology instructor at St. Francis Xavier University specializing in boreal and Northern saw-whet owls. These owls possess acute senses, making them efficient predators, especially larger owls that can hunt rodents even under thick snow layers. However, the diminutive saw-whet owl faces challenges in catching prey in deep snow.
As a result of the difficulty in finding food, saw-whet owls have been observed more frequently in both rural and urban areas this winter, particularly near bird feeders attracting mice and small birds. Despite the perception of prolonged and heavier snow this season, CBC meteorologist Ryan Snoddon notes that the current snowfall is within the usual range for winters in Nova Scotia.
In a noteworthy encounter, a saw-whet owl was recently spotted at Hatfield Farm in Hammonds Plains, Nova Scotia, seeking potential prey in the barn. Cherie Hatfield, the owner, emphasized the importance of coexisting with wildlife during challenging winter conditions. She recounted the owl’s brief stay in the barn before naturally moving on to find food.
Experts emphasize the need to respect the space of these owls when spotted in yards, urging people to avoid disturbing them. Lauff advised against approaching these owls to prevent causing stress, particularly during their crucial hunting periods at dusk. Snow cover can offer advantages and challenges for birds of prey, allowing for easier prey detection but also presenting obstacles if the snow crusts over, hindering their hunting efforts.
Hope Swinemar, the founder of Hope for Wildlife in Seaforth, explained the impact of harsh winters on wildlife, highlighting the resilience of most animals in adapting to challenging weather conditions. Swinemar noted that while there hasn’t been a notable increase in saw-whet owls requiring assistance this year, the center has seen an uptick in barred owl rescues due to road accidents during dusk hunting.
In conclusion, while snowy conditions may pose difficulties for wildlife, birds and animals are adept at adapting to various challenges presented by winter. The natural world’s resilience in navigating harsh weather conditions continues to be a testament to their survival instincts.
