Below is a map that birders have been collaborating on showing approximate locations of Snowy Owls across the US and Canada during this already exceptional irruptive season. Here in Pennsylvania, most Snowy Owl records come in January and February so we may get some in the coming months as well. If you come across a Snowy Owl, it is always an interesting exercise to attempt to age and sex the owls. Most birds can be aged and sexed in the field with reasonable looks. The key differences are in the amounts of dark edging on feathers, thickness of tail bands and presence of extensive white bib. For a good overview, read Kevin McGowan’s overview that features several specimens for comparison.
