Rhoda and I had just about the whitest Snowy Owl I've ever seen fly past Tiscornia (along with close to a thousand ducks, mostly mergs). It landed briefly on the South pier before being flushed by gulls to Silver.
I drove over and phone-scoped the bird. With the scope at 60x, the phone at 2x, and some cropping these are probably about 150x
The bird was flushed by beachwalkers
Most of the Snowies that come south are first year birds with much heavier markings. This was an adult, likely a male.
