The population of Purple Martins at the Old Manns Harbor Bridge this summer of 2022 is very low. This repeats what we have seen here during the past two roosting seasons. We do not yet have a satisfactory explanation of why this has occurred. As we learn more we will post it here and on our Facebook. Meantime, anyone visiting the roost this summer likely will see a much smaller group of roosting families than we have seen in past years. Thanks for your interest. Please note: Crystal Dawn is not scheduling group cruises to the bridge this season.
