The heavy snowfall in Nova Scotia this winter is driving small owls, particularly the Northern saw-whet owl, into residential areas in search of food. Randy Lauff, a biology instructor at St. Francis Xavier University specializing in boreal and Northern saw-whet owls, explains that the snow cover has made it challenging for these tiny owls to hunt their usual prey of mice, voles, and shrews. Unlike larger owls that can rely on their strength and keen senses to catch prey hidden under thick snow, the saw-whet owl’s smaller size limits its hunting abilities.
As a result, these owls are increasingly being seen in rural and urban settings near bird feeders, not for the seeds but for the small creatures attracted to them. One notable sighting occurred at Hatfield Farm in Hammonds Plains, N.S., where a saw-whet owl took refuge in a barn before moving on. Cherie Hatfield, the farm owner, believes the owl was seeking food due to the harsh winter conditions.
Experts like Lauff and Hope Swinemar emphasize the importance of giving these owls space and not disturbing them, especially during the hunting hours just after dusk. Snow cover can both aid and hinder bird hunting, with increased visibility of prey against white snow but potential challenges if the snow crusts over. Swinemar notes that while the wildlife rescue center hasn’t seen a rise in saw-whet owls needing assistance, there has been an uptick in barred owls needing help, often due to accidents on roads.
In conclusion, the natural world is resilient, adapting to harsh winter conditions, and experts advise respecting the wildlife’s space and needs during this challenging period.
