May I ask pls, what time of day was this at and where exactly you saw the Snowy? I was out this afternoon looking for her and I couldn't find her! I drove literally all around (down Liverpool to the docks... then up liverpool, down Annland... up and back down the next street... down towards Bayly... south down West Shore (?) all the way to the end, past Rotary Park... down to the end.. turned left... east along the bumpiest road ever!! back out... along the west shore docks...). This was between 12:30-2pm today though... so no doubt I was too early. You're so lucky to have seen her! And what lovely photos!
On the upside, I did see an amazing Red Tail Hawk today (photo posted as well) along my travels around the Bay... so all was not lost. 
Wow.....sorry you missed the Snowy. We met a few others who were there to see it. We arrived at about about 12:00 PM and started at the park, north of the marina. Someone saw it there on the wooden posts out in the water. As we were arriving, we saw it flying out over the water and land on a tall tree at the lakefront. We decided to head over to the main parking lot. On the marina side, there is a trail on a peninsula that leads over to the bay. This was where the tree was but, when we got there it was nowhere it sight. We decided to head over onto the ice, as we spotted the Redheads and other waterfowl amongst the masses of geese. After freezing our butts on the water for over an hour taking nice shots, just as we were leaving the ice the Snowy flew over and again landed in the same tree. A few others saw it too and, a small group gathered nearby. We did not want to scare it but, it happily stayed up on the top of the tree. This was about 1:45 PM. We left at about 2:50 PM and it was till there as we left the parking lot. Hope this helps you. Maybe it will be there tomorrow. Good Luck.
Oh also saw a small group of Trumpeters.....
