Here is the link your spouses will come to dread (unless they happen  
to be bird brains too):

http://cincinnatibirds.com/goodbird/sighting.php

I like to start with the sightings myself. Make sure you browse all  
the links on the left. The database and daily bird lists are great  
tools.

Plus lots of other stuff to kill time when you're supposed to be  
working...

Enjoy!
