Hi Katie, Western Bluebirds are breeding all around Ft. Lewis in a broad
area roughly between Puyallup, Eatonville, Tenino, Olympia, Tacoma. If
you were to connect these cities (in order) with a line, that would
roughly encircle the major part of WEBL breeding distribution in this
area. Outliers exist In King, Mason, and Callam, Jefferson, and Kitsap
counties. As far as plowing goes, the thousands of bluebirds nesting in
the wheat fields of eastern Washington don't seem to mind. What they
really need are cavities. If the owners put up boxes, I bet they'd end up
with bluebirds. If you want to see the BBA data for this species, point
