Wood ducks are a species of focus because they are cavity nesters and suffer from lack of habitat in many areas since swamps have been cleared of old growth trees. Since 2004, the Spring Island Trust has maintained wood duck nesting boxes in locations around the island. Between December and June every year, Trust staff and volunteers check the boxes for nesting activity and count the numbers of eggs laid and duckling hatched. While the number of boxes has varied some over the years, the monitoring has showed that Spring Island has been used consistently by wood ducks as habitat to nest and raise ducklings in.

As of 2020, there are a total of 19 nest boxes on Spring Island. That year nine clutches of eggs were laid, seven of which were successful with a total of 76 ducklings hatched from the 115 eggs. In 2019, 86 ducklings hatched from the 130 eggs that were laid. Since 2016, the number of nesting attempts, eggs laid, and eggs hatched has gradually decreased. At present the cause of the decline is not known. Possible explanations include fewer breeding adults present, increased human activity in some places on the island, and/or altered habitat conditions due to Hurricanes Matthew and Irma which occurred in 2016 and 2017 respectively.
