Protecting Endangered Species at Mass Audubon

Mass Audubon protects dozens of endangered species with different strategies from habitat protection, science-based management plans, and advocacy. Here are just a few of the ways we’re watching out for rare and declining wildlife.

Helping Shorebirds Share the Beach

Piping Plovers and Least Terns nest on the ground along Massachusetts’ sandy beaches, but they need space to raise their fluffy, tennis ball-sized chicks.

Mass Audubon protects nearly half of the state’s Piping Plover and Least Tern population from shoreline development and human disturbance, and works with the state to manage the rest under our Coastal Waterbird Program.

While most people notice Mass Audubon’s effort to directly protect shorebird nests—sometimes including ranger patrols or symbolic fencing to keep beachgoers a healthy distance from nests— the Costal Waterbird Program also works through environmental education and science-based political advocacy.

Thanks to these efforts, Piping Plovers have rebounded from 135 pairs in 1986 to more than 800 pairs in 2020, and they’re still on the upswing!

Keeping Sea Turtles out of the Cold

Every November, volunteers and staff from Wellfleet Bay Wildlife Sanctuary rescue cold-stunned sea turtles from the chilly shores of Cape Cod Bay. Most of them are the smallest and rarest of the sea turtles, the Kemp’s Ridley, which are already threatened by abandoned fishing gear and plastic pollution.

Climate change is driving an increase in autumn strandings. Ironically, warmer waters in summertime mean more Kemp’s Ridleys—which normally stay south of Cape Cod— are migrating further north. When waters cool and turtle instincts say “go south,” turtles are trapped by the unique shape of Cape Cod and often become hypothermic before they make it around the tip of the Cape.

Since the 90s, the average number turtles in Cape Cod Bay—and the average number of strandings—has skyrocketed. Normally, Mass Audubon partners with the New England Aquarium to rehabilitate and release cold-stunned sea turtles. This past winter, there were so many strandings that we had to send them to facilities as far away as Houston for treatment and release!

Advocating for Legal Protections

While many species are threatened or declining, the word “endangered” only refers to a species that’s protected under the federal Endangered Species Act (or the Massachusetts Endangered Species Act, which protects species at risk locally in Massachusetts). These laws require the state and federal government to monitor and conserve habitat for species at risk of extinction

Outside of directly protecting rare wildlife on our sanctuaries, one of the most powerful things we can do for rare species is advocate for their legal protection. After our Breeding Bird Atlas showed precipitous declines in Saltmarsh Sparrows, American Kestrels, and Eastern Meadowlarks, Mass Audubon petitioned the state to list each species as Endangered. We also stand up for the both the federal and Massachusetts Endangered Species Acts when they’re under attack.

Will We See Cicada Brood X in Massachusetts?

People are buzzing with excitement (and maybe a little fear) about the possibility of billions of cicadas emerging after almost two decades of living underground. If you fall into the excitement category and hoping to witness this phenomenon here in Massachusetts, alas, you’ll have to hold on for a few years. 

When they emerge after 17 years underground, swarms of Cicada Brood X could be spotted in parts of the Southeast, Midwest, and North Atlantic. While we may not experience the 2021 version this event, we do have our fair share of annual cicadas that contribute our summer soundtrack.

Cicadas in Massachusetts 

Of the more than 2,000 species of cicadas that exist worldwide, nine species have been documented in Massachusetts including one periodical cicada species and eight annual cicada species. The most common cicada here in Massachusetts is the “Dog Day” Cicada.

The annual, dog day cicada emerges every one or two years. It’s approximately 2.25 inches long, medium brown, with a green venation (the vein structure in its wing). Though we hear them each summer, these cicadas are solitary insects; we seldom see them. 

Hearing Cicadas 

Cicadas are sometimes referred to as harvester flies because their “song” is characteristic of late summer days. This astonishingly loud sound comes from a pair of organs called tympana located at the base of the males’ abdomen. 

The tympana are complex mechanisms that consist of a series of three membranes inside a resonating chamber. A powerful muscle flexes one of these membranes (the tymbal), somewhat in the way we pull and release a metal, can top to create a loud click. Done in rapid succession and amplified by the resonating chamber, the familiar whine is produced.

We may not witness Brood X this year, but those in Southeastern Mass or on the Cape and Islands can anticipate being treated to Brood XIV, emerging summer 2025.
