This 3 January 2019 video from the USA says about itself:
The Cornell Lab‘s multimedia unit partnered with the Atlantic Coast Joint Venture to produce this promotional video for the ACJV website.
Tidal marsh birds are facing a crisis that is playing out in nearly every state in the Atlantic Coast Joint Venture. Sea-level rise, urbanization and other human impacts have degraded this narrow band of coastal habitat, pushing many bird populations into steep decline. Recognizing the urgent need and our shared responsibility for salt marsh habitat conservation, the ACJV partnership is directing its collective attention to conserving the Saltmarsh Sparrow, Black Rail, and American Black Duck and the coastal marsh habitat they inhabit.
