Mass Audubon Wellfleet Bay Wildlife Sanctuary has been a popular area for Purple Martins this nesting season! The colony, which consists of two racks, each holding a dozen PVC gourds for nesting, was nearly a full house. Overall, Wellfleet Bay saw a 22% growth in fledged Purple Martins compared to the 2022 season. Learn more about the Purple Martin colonies at Mass Audubon: https://bit.ly/3PaP42w | Mass Audubon

Purple martins on the East Coast of the U.S. depend on humans to provide their nesting sites, which is why we have a purple martin hotel at the Smithsonian Conservation Biology Institute in Front Royal, Virginia. Each year our keepers and partners band wild purple martin chicks born at SCBI, which means they put bands on their legs to help identify them. They also weigh each chick before placing it back in its nest. #WeSaveSpecies | Smithsonian’s National Zoo and Conservation Biology Institute
