Yesterday I was out running errands and stopped at the Havegärd Bird Feed Outlet Store to replenish my dwindling stock of wild bird seed. If you've never been be sure to check them out. Likely the best selection and pricing for large quantities of bird feed and supplies on the planet. East side of highway 42/57 just south of the Sturgeon Bay. I digress.
Upon entering the store the guy at the register asked if I had something to take a photo. To which I replied: You bet. Got my phone with me. Gesturing, he said to go outside and checkout what was perched on the utility pole at the side of the road.

Meet Bubo scandiacus. A snowy owl. Yowza cool! It is not unusual to learn of reports of them appearing along the Lake Michigan coastline in the winter months; yet observing one in person is an event worthy of celebration.
This is a big bird tipping the scales at 3.5 to 6.5 pounds. Standing up to 28 inches in height and with a wingspan of up to 4.8 feet this is the largest owl in North America. It sports bright white
plumage, large yellow eyes and larger feathered talons. Home territory to this bird is the treeless
tundra above the Arctic Circle. From time-to-time small numbers may migrate to southern Canada and the northern reaches of the contiguous United States. Larger numbers infrequently show-up in an event called an
owl ‘irruption’.
What is the cause of an irruption? Possibly fluctuations in food supply. It is hypothesized
that a temporary abundance of lemmings allows the owls to successfully raise
large families and then these young owls disperse southward by the hundreds to
avoid competition with older birds for winter territories. Similarly, shortages of prey prompt these birds to move from their normal wintering grounds.
These owls hunt during
daylight hours and will roost on almost anything. They like flat open land
(it’s what they know), sometimes sitting on the ground, but more often on hay
bales, fence posts, telephone posts, rock piles, muskrat houses, tree snags,
silos, and other structures. Snowy Owls
will dine upon almost any live thing that moves - voles, mice, lemmings,
waterfowl, rabbits, muskrats, weasels, and pigeons. Other bird species are
taken as well. They swallow small prey whole.
It is notoriously challenging to estimate population numbers for this iconic species. Nevertheless, recent data suggests that the snowy owl population is much smaller than previously thought and declining. This bird is now listed as vulnerable to global extinction.
Because these birds are not accustomed to
seeing humans they likely will appear fearless in your presence. Approach them with caution
and observe them at a distance. Do not
flush them. The rare sighting of
this beautiful bird can be a once in a lifetime experience. Sorta like seeing a ghost.
