There seems to be a lot of conflicting information about aging Snowy Owls on the internet, no surprise there. From what I can gather, one can only confidently ID very white birds as adult males, and very dark birds as young females. Everything in between could go either way in terms of aging/sexing.
Despite seeing 125 Snowy Owls on Saturday, I didn't see any that lacked any noticeable barring. Which is a good indication that there are very few or no adults around. However, there was considerable variation in the birds we saw.
Instead of ordering the photos chronologically, I decided to try to order them from darkest to lightest. Just click on the first image so that it fills the screen and then you can scroll from image to image.
All, except 3 of these photos, are of different owls.
Some group shots:
This bird was at the very tip of Cape Race:
Snowy Owls weren't the only white dots on the barrens, we saw over 50 Caribou that day:
This tame female kingfisher was at Quidi Vidi recently:
