Block Island National Wildlife Refuge is a critical migratory bird stopover point on the Atlantic coast. Fruit-bearing shrubs provide essential food for the species of birds that come to rest there. For many bird species the waxy-gray berry of the native Northern Bayberry shrub holds little nutritional value, but some of the species, such as the yellow-rumped warbler, have a special enzyme that can turn the berries' wax into energy. These wild lands are also known internationally for spectacular bird watching, and provide a breathtaking walk along the barrier beaches.
The reverse (tails) design depicts a black-crowned night-heron flying over a view from the beach at Cow Cove looking towards Sandy Point. The North Lighthouse is seen in the background. Inscriptions are "BLOCK ISLAND," "RHODE ISLAND," "2018," and "E PLURIBUS UNUM."
