Thanks Josh for the pointer -- that's the place to look for accepted WBRC records -- If you are looking for a bit more info on the records listed on the spreadsheet at that link, all previous WBRC formal reports are online at the wos website as well at http://wos.org/wbrcreports.html

Regarding Black-throated Blue Warblers -- 11 previous records have been accepted in the state, 6 on the west side and 5 on the east side. Most of the records come from late fall migration or winter:
1 in late September
3 arrived in October
4 were first found in November
1 in December [the recent record also was first seen in December]
The two outliers:
1 record was found in Olympia in March [maybe a bird that overwintered nearby but was not found until then?]
1 in 2012 in June - presumably our only record of a northbound migrant.

9 of the 11 earlier records have been of males, perhaps a sign of their relative ease of identification.

4 of the records prior to the recent one were seen for more than one or two days, and the most recent of those was in 2007 in Walla Walla County -- as Josh said, it has been a while since we've had a cooperative Black-throated Blue in the state like this current one.
