Data for these birds are summarized in Table 6. Relatively few of these species are directly associated with the water- side communities; most of these birds belong to the varied habitats that occur within earshot of the marshes and rivers. Discussion Since I spent most of my time near water, I have concentrated on the waterside communi- ties. I will be discussing other communities only in so far as they adjoin the riparian ones. The records in Table 3 show clearly the divi- sion between relatively rapid rivers and stand- ing water areas. Common Merganser and Spot- ted Sandpiper were the only species found gen- erally in all flowing water areas, whereas many water birds were seen regularly in the waterfowl areas. On the basis of the water birds (Table 3), we could recognize two sub-communities with flowing water — the more rapid, upper reaches with mergansers and sandpipers and few other birds; and the slower, downstream stretches along which many standing water species occur locally. The small, alder-grown brooks might be considered a third sub-com- munity, in which mergansers are generally lacking and in which Woodcock Philohela minor (not included in Table 3) occur. How- ever, I did not survey enough of this habitat to provide numerical data on its bird life. The standing water areas were chosen for study because waterfowl were found there regu- larly. Black Ducks Anas rubripes were on nearly.
