Between Moon Tides: hacking nature to save the saltmarsh sparrow

Sea levels are rising in New England at some of the fastest rates in the world. On a quiet ribbon of saltmarsh in Rhode Island, septuagenarian Deirdre isn't prepared to accept the loss of her beloved saltmarsh sparrow, which risks becoming extinct by 2050 due to elevated high tides inundating nests and drowning fledgling birds. Leading a team of citizen scientists, Deirdre unravels the secret to finding delicate nests amid thick marsh grass, while they design and deploy a low-cost 'ark' to try to raise vulnerable sparrow nests to safety. Will this be the year they manage to save them?
