This year presents a unique opportunity to observe snowy owls in southern Canada. Over the weekend, The Owl Foundation, located in Ontario’s Niagara region, shared on Facebook that they had already taken in two young snowy owls, hinting at a potential increase in snowy owl sightings. Such occurrences, known as irruptions, involve a sudden surge in the local population of a species, such as snowy owls migrating south from the Arctic. Researchers have noted an earlier-than-usual presence of young snowy owls in southern Canada and the northern U.S. This trend offers a chance to witness these rare Arctic visitors, recently listed as threatened by the Committee on the Status of Endangered Wildlife in Canada.
Brian Hayhoe, a wildlife biologist at The Owl Foundation, mentioned that in recent winters, the center had received zero to two snowy owls annually, typically not until December or January. Reports from other wildlife centers in Ontario also indicate higher numbers of snowy owls observed earlier than usual, suggesting a notable pattern shift. Scott Weidensaul, associated with Project SNOWstorm, highlighted increased snowy owl sightings in central and western Great Lakes and the Prairies, with some even reaching as far as British Columbia.
Irruptions, significant movements of birds occurring periodically, contrast with regular migrations. Notably, snowy owl irruptions bring these birds south in substantial numbers approximately every six years. While previous irruption events occurred in 2017-2018 and 2020-2021, the most significant irruption in recent memory happened in 2013-2014, with thousands of snowy owls venturing south from the subarctic regions.
This year’s early high snowy owl sightings suggest a potential irruption, yet confirmation will likely come in January when more owls migrate southward. Snowy owls are typically found in agricultural fields and coastal regions during the winter, making these areas prime locations for owl enthusiasts. Observing these majestic birds can offer a unique connection to nature, but it’s crucial to maintain a safe distance to avoid disturbing their natural behaviors.
With snowy owls facing threats like habitat loss and climate change, efforts to protect these magnificent creatures are vital. Scientists have recommended listing snowy owls as a threatened species due to a significant decline in their population. By appreciating and understanding snowy owls, individuals can develop a deeper appreciation for Arctic wildlife and the challenges they face in a changing environment.
