A shorebird survey route was initiated in 2000 as a part of the International Shorebird Survey operated by the Manomet Center for Conservation Sciences. This route is located within the lower Duck River Bottoms. Surveys are scheduled to be conducted three times each month from April 1 through June 10 for the spring migration. Fall migration surveys cover the period of July 11 through October 31. Total numbers for each species are recorded by pool number.
The data is not currently entered by the refuge into a database. The completed data forms are sent to Manomet and a copy is retained in the refuge files. The refuge uses this data to improve the accuracy of the Refuge Bird Checklist, to develop a better knowledge of the chronology of the shorebird migration through this area, and to better time the drawdowns of the impoundments to coincide with the peak migration periods.
- Shorebirds undertake some of the longest migrations known. Red Knots breeding in the high latitudes of the Canadian Arctic will spend the winter in southern South America.
