Just thought I would add that the guys were back today - at least 100 of them!
I setup the K-5 with catch-in-focus for a couple hours - I now have 1068 images to sort through! Once I get a handle on those images, I think I am going to start a new post about my visitors in the Wildlife section as it seems more fitting.
I also set up the Q to take some video of the frenzy - it's hard to explain without actually seeing it. During the video you will see a little snow come down once in a while - that is from the 40 or so of them that were on the roof waiting to get into the action.
I'll update this thread with a link to the new one later this coming weekend.
