a Vegetation types: SS = scrub-shrub, WM/SS = wet meadow/scrub-shrub, WM/SS/LS = wet meadow/scrub-shrub/loosestrife, WM/LS = wet meadow/loosestrife, WM = wet meadow, IC = inland cattail, CC = coastal cattail, CB = coastal bulrush.
b Species observed within the sampled vegetation type but not on plots. c American Coot and Common Moorhen were grouped together because these species were most often observed by call only and their calls are difficult to distinguish.
