Variables
Wilson's Warbler
Occurred the most disproportionately in hexagons with annual
precipitation more than 1134 mm and April maximum temperature
more than 11� C (hexagon maximum). Somewhat less likely where
annual precipitation less than 432 mm and terrain is nearly flat. The
logistic regression analysis showed positive or negative association
with Douglas-fir - w. hemlock - red cedar forest, elevation (hex. avg.),
the extent of public land, April precipitation (hex. avg.), and-to a
lesser degree-topographic variation and July precipitation (hex.
med.).
