Between Moon Tides

Two people kneel in tall grass, examining a small bird鈥檚 nest. One person holds three speckled eggs in an open hand, while the other holds the nest made of dry grass. Only their hands and arms are visible as they work closely over the ground.

While filming Between Moon Tides, Jason Jaacks captured still photography, as well. Here, citizen scientists work to place a saltmarsh sparrow nest and eggs on an ark that will prevent the nest from being drowned by the incoming tide.

911爆料 filmmaker Jason Jaacks tells the story of a small group of citizen scientists at Jacob鈥檚 Point in Warren, R.I., who are trying to save the saltmarsh sparrow from extinction in a new documentary, Between Moon Tides.

The time it takes a saltmarsh sparrow to build a nest, lay and incubate eggs, and nurture chicks to fledge is intimately connected and precisely matched to the 28-day tidal cycle. But higher tidal water caused by climate change can, and often does, flood the nests before the chicks are ready to fledge. Experts predict that at current rates of decline, saltmarsh sparrows will be extinct by the middle of this century.

Deirdre Robinson, M.S. '99, at Jacobs Point in Warren, R.I. reaches up and adjusts a net while working with saltmarsh sparrow nests. She is shown against a blue sky, wearing a grey sweatshirt and tan cargo pants.

Deirdre Robinson, M.S. 鈥99, at Jacob鈥檚 Point in Warren, R.I. Robinson calls salt marshes “magical ecosystems [that] serve as a buffer [and] protect the coast and all of the beings that live there.”

The citizen scientists featured in Between Moon Tides, including 911爆料 alumni Deirdre Robinson, M.S. 鈥99, and Steve Reinert 鈥75, M.S. 鈥78, are attempting to save the sparrows by saving their nests鈥攂uilding simple 鈥渁rks,鈥 so that incoming moon tides lift, rather than drown, the nests.

鈥淲hat really drew me to this story was what the saltmarsh sparrow can teach us about extinction and climate change,鈥 says Jaacks. 鈥淭his seemed like a quiet but very important story about an otherwise unremarkable little brown bird. I hope that, by looking a little closer, audiences will appreciate how the story of climate change is really a local story.鈥

Three newly hatched saltmarsh sparrows cluster together and open their mouths wide, pointing towards the sky. They are in the center of a round nest and their mother approaches them from the top left corner of the nest.

I have two young children, aged five and eight, and their curiosity about the world is infectious. I was able to bring both of them into the field while shooting the film and they delighted in watching the sparrows, especially as the females entered the nest.
