We are into the 4th week of April and Snowy Owls continue to be seen. Keep in mind the large numbers of Snowy Owls that moved southward into the United States this past Fall and Winter. Those owls should be on the move northward now and likely some owls will pass through the Ottawa area on the northbound journey.
Last I checked there were still many snowy owls south of the border in places such as Massachusetts, Illinois, Vermont, North Dakota, Maine etc. This bodes well for people in Ottawa as we will likely see snowy owls for the next two weeks when some of these birds pass through the Ottawa area.
