At the camp, we have Flying Squirrels who, as you might know, are nocturnal so I feed 'nitely', these fellows 'glide' from tree to tree, and are regular visitors to my feeders.
The second picture is of a nest of babies, we were lucky enough to see and get pics of (In a dart board with doors on it) back in the spring of '06, what a treat that was !! The mom eventually moved the babies but what a catch for me, awesome!!
