Predicted relationships between probability of nest occurrence and two forest habitat variables included in the Field225 model (18 variables originally considered) for the Western Region of the Williamson’s sapsucker Area of Occupancy in British Columbia, 2006–2008.

<p>Grey points depict nest occurrence (‘Nest’) or a random point (‘No nest’), and the title of each plot indicates the habitat variable. Solid lines indicate predicted values and thin dashed lines represent the 95% prediction interval. Horizontal line depicts proportion of points that were nests (i.e., the baseline probability of response variable having a value of 1).
