These include the Northern Phalarope and the Red Phalarope . It is felt that normal shipping activities are likely to have inconsequential effects on sea-associated birds when the birds are in the water, since the birds are highly mobile and may avoid the ship by flight or by diving. However, seabird nesting colonies are felt to be very susceptible to disturbance from the passage of both ships and aircraft. The noise of ships and aircraft passing in close proximity may cause birds to abandon their nests in fright. Young and eggs left alone in the nest are also more susceptible to predation and harsh weather.
Waterfowl are less likely to encounter ships as they nest inland.
