In recent years I've been hearing them in an open Douglas-fir stand
adjacent the Mima Mounds Natural Area in Thurston County, the earliest
dates being:

2007: 15 April
2008: 12 April

However! I don't get down there all that regularly, so the true start
date is days to weeks earlier.

I was there yesterday, and heard none.

The latest date I've recorded is 8 July in 2001.
