Primary Refuge objectives include offering food, rest, and protection for birds, especially in spring and fall migration, and providing nature-oriented recreation for people. Public use includes nature study, especially bird watching and observation of concentrations of migrating waterfowl from convenient overlooks, walking nature trails, photography, hunting, fishing, and leisurely driving through the Refuge. Birding is best from March through November. Peak migrations of waterfowl are in mid-April and early October. May is the best time to observe warblers, with the most species likely to be seen between the tenth and the twenty-first of the month.
Visitors can readily view summering waterfowl and their broods.
One can always expect to see some interesting birds on a tour of the Refuge, regardless of the season.
