To add to Alans suggestion.
Depending on what types of birds you are looking for, Puget sound is right there, taking a ferry across it will give you lots of chances to shoot all sorts of birds. Especially if you take a ferry that has a stop at one of the smaller islands. It would be a very fun way to spend a day. I know when I used to live in Washington, some times I would go up to Seattle just to go ride the ferrys. It was a very cheap form of entertainment for me.
