Number of days tracked on Tomales Bay, CA and number of steps ending in each wetland type for GPS tagged great egrets. Capture sites are as follows: CG = Cypress Grove; TP = Toms Point; WC = Walker Creek. Models failed to converge for birds with few observed steps in shellfish aquaculture areas (indicated by *), so these egrets were excluded from statistical analysis. Total number of days is less than the number of days comprising the date range for egrets that left the study area for migration or other movements.
