Looks like someone was looking for a mate.
As I understand it, the male built a nest, then went looking for a mate. She came and checked it out, and apparently was checking him out as well.
I thought they made a cute couple.
Again, crappy quality from shooting through three panes of glass, but I got some photo's...
We can't all be Paul Almendinger's after all...
...If we were, his photo's wouldn't stand out. ;-O
