ArticBowMan -
Washington allows 3 birds to be taken in a spring season, one of them has to be an eastern (located in western Washington). The season runs from April 15 to May 15, unless you get drawn for an extended season.
Merriams and Rios are plentiful and an almost guarantee - the easterns are the tough bag. There are a lot of them, but getting to them can be difficult, and they are for sure the hardest ones to hunt.
Here is some info if you want to check into it a little more:
