Save Bobolinks This Year Through The Bobolink Project

Applications from interested farmers have been rolling in as Bobolinks have been starting to make their way northward from South America. What better way to welcome them back than protecting habitat where they can safely raise their young? People who support The Bobolink Project do just that.

The Bobolink Project is an innovative model that was designed to connect conservation-minded donors with farmers who want to protect birds on their fields, but need a little financial help to do so.

You can save Bobolinks

The number of acres The Bobolink Project protects is directly tied to how much we can raise in donations. You can support this work and protect privately-owned habitat for grassland birds by donating to the project and spreading the word to all of your networks. This project simply wouldn’t exist without people, like you, who care deeply for birds.

The Bobolink Project saves hundreds of Bobolinks each year. Let’s make 2021 just as successful!

How it works

Interested farmers apply to The Bobolink Project with a dollar bid/acre that is low enough to be competitive but also sufficient to provide them with some financial help to offset the loss of income from the hay that would otherwise be cut. Grassland sizes must be a minimum of 20 acres to be considered. At the same time we accept donations from Bobolink-loving donors and pool them until we’re ready to make decisions in mid-April.

In order to select which farms will be included we do a uniform reverse price auction, which is described on our website in more detail. The number of acres that we can protect is determined by how much we can raise each year.

Once we determine which farms will be selected, we draw up legal contracts with those farmers and wait for the Bobolinks to arrive, start building nests, and raise their families.

Celebrating 30 Years of the Massachusetts Endangered Species Act

Conservation success stories rest on a bedrock of strong environmental laws. Many of Massachusetts’ most notable species recoveries, from the resurgence of Peregrine Falcons in cities to Bald Eagles populations’ dramatic turnaround, are grounded in the legal provisions of the Massachusetts Endangered Species Act (MESA).

MESA provides robust protections for over 400 local, rare, and declining species. With the chaos of 2020 disappearing in the rearview mirror, this is also a time to reflect on and celebrate positive achievements from past years. To mark the 30th anniversary of MESA, passed in December of 1990, take a moment to learn about the history of this sweeping and ever-relevant legislation.

Laying the Groundwork

Conservation laws in Massachusetts date back to 1818, when the state passed the first bill to protect songbirds from sport and food hunting, and by 1855 a broader act was instituted that protected all “nongame” birds.  By the end of the Civil War in 1865, the genesis of today’s Massachusetts Division of Fisheries and Wildlife came about with the establishment of a two-person commission “to investigate the obstructions to the passage of fish in the Connecticut and Merrimack Rivers.”  By 1886 this grassroots political conservation effort became known as the Commission on Fisheries and Game. 

As this incipient conservation machinery continued to evolve, by 1908 Edward Howe Forbush was appointed as the Commonwealth’s first State Ornithologist.  After Mass Audubon’s Founding Mothers spearheaded the national Migratory Bird Treaty Act in 1918, the state was spurred to create the Massachusetts Department of Natural Resources. Embedded within this department, the Division of Fisheries and Game was essentially charged with conserving and managing the Commonwealth’s diversity of wildlife, plants, and habitats for the benefit of Massachusetts residents.

Conservation is a Team Effort

Through the years environmental legislation gradually grew stronger, and by 1973 the federal Endangered Species Act was passed.  This landmark legislation soon saw The Nature Conservancy (TNC) develop a network of natural heritage programs across the country that would eventually oversee state level stewardship for all elements of biodiversity, including plants, animals, and natural communities. In 1978 Massachusetts became the fourth state to formally establish a Natural Heritage Program, which by 1983 had morphed into today’s Natural Heritage and Endangered Species Program (NHESP).  By 1990, Massachusetts Governor Michael Dukakis signed the Massachusetts Endangered Species Act into law, designating species as Endangered, Threatened, or Special Concern, and providing legal protections for each status.

Since then, Mass Audubon has played a key role in partnering with the state to protect the Commonwealth’s most imperiled (“state-listed”) animals and plants through the efforts of the NHESP.  Examples include such rare species as North Atlantic Right Whale, American Bittern, Red-bellied Cooter, Marbled Salamander, Northern Redbelly Dace, Early Hairstreak, Yellow Lady’s-slipper. Massachusetts publishes a complete list of state-listed species online. In other cases the NHESP’s Habitat Management Program focuses its conservation efforts on threatened habitats (e.g., vernal pools, pine barrens, sandplain grasslands, and calcareous fens).

As we enter 2021, the conservation efforts driven by the NHESP and MESA continue apace. For more information about the history of the Massachusetts Natural Heritage and Endangered Species Program and the Massachusetts Endangered Species Act, check out the November issue of Massachusetts Wildlife magazine, or visit the Fish and Wildlife Service homepage for MESA’s 30th anniversary.

When a city shut down, White-crowned Sparrows sang quieter, more complex songs

You may have heard it or even said it. “Nature is healing” has become a common refrain during the COVID-19 crisis, perhaps as a way to look for a bright side of a tragedy.

And while some examples are simply wishful thinking, like false stories of dolphins’ return to the canals of Venice, there is real evidence that less human disturbance during the pandemic changed how Californian White-crowned Sparrows sing.

Less Noise, More Song

Researchers conducting a long-term study on White-crowned Sparrow songs saw an opportunity in the lull of a lockdown. Before the pandemic, the San Francisco-based team had studied how increases in city noise changed birds’ singing behavior. But this April, traffic noise fell to its lowest level since 1954.

In normal years, the researchers had found that White-crowned Sparrows compete with city noise by singing louder, higher-pitched, and simpler songs.

While simpler, louder songs rise above the hum of traffic, they come at a cost: males can’t sing both loudly and well. That disadvantages the fittest male White-crowned Sparrows, which advertise themselves with more complex songs. For females, which pick mates based on song quality, a city full of males shouting a limited series of notes curtails their ability to choose a good partner.

But just days after a stay-at-home order went into effect, urban sparrows reverted to singing the soft, complex songs of their rural counterparts.

The researchers found that their calls carried twice as far as before, both because of the varied tones of the song and because of lower ambient noise. And according to the team, males fight less over territory when they can hear each other’s songs from further away.

This study shows how quickly birds can return to natural behaviors after human disturbance are removed. Of course, there are many other kinds of human pressures on ecosystems that leave long-lasting or permanent effects– just not in this case.

So, if you think you heard more birds this summer during the pandemic, you might be on to something. Regardless of whether local birds change their singing behavior, less noise pollution probably means that we hear more birdsong– a thin silver lining in itself.

Good News Update: Barn Swallows Successfully Nested at Conte National Wildlife Refuge

Barn Swallows nesting at the Silvio O. Conte National Fish and Wildlife Refuge have had a successful season in 2020 in the Fort River Boat House. The full final report is available here.

Season Summary

We estimate that 30 – 38 pairs of Barn Swallows nested in the Fort River Boat House in 2020.

Of 98 adult swallows banded at Fort River in 2019, 27 were recaptured in 2020 (28%). This number is probably lower than the actual number present due to fewer banding days conducted this year during the pandemic. This return rate is similar to rates found in other studies of Barn Swallows. While a 28% return rate may not seem particularly high, remember that swallows banded in 2019 made two long migrations to and from South America before returning to breed in Massachusetts in 2020. And, because returning Barn Swallows don’t show perfect site fidelity, some individuals may have simply chosen to nest elsewhere in the area.

This Success Informs Future Conservation Actions

Aging barns occupied by Barn Swallows are a common feature in New England’s historical agricultural landscape, and sometimes these structures simply cannot be saved. Thanks to the help of collaborator Andy French, project leader at the Conte Refuge, we have learned important lessons about how to attract and relocate Barn Swallows into alternative structures where they can be protected in cases where occupied barns must be removed. Some of the steps that were taken included:

  1. Collection of some nests after the breeding season to use in attracting swallows the following year to a different, more secure nesting location. A majority of nests built in 2020 were built on top of “seed” nests that had been harvested in 2019.
  2. Placement of nesting structures, hung from the Boat House rafters, to provide nesting sites. Some of these structures also included defecation screens that prevented swallow droppings from raining down on equipment below—an important consideration for private landowners who often have to deal with bird damage to their tractors and other farm equipment.
  3. Playback of Barn Swallow vocalizations was used in 2019 to advertise the availability of the Boat House site to pairs that were nesting in the nearby Bri Mar Stable. In 2020, we decided not to play audio recordings because Barn Swallows had already begun to move into the Boat House in 2019.

Next Steps for Aerial Insectivore Conservation

Mass Audubon also hopes to continue to contribute to a developing US Fish and Wildlife Service initiative aimed at conserving aerial insectivores (e.g., Barn Swallows, Cliff Swallows, Chimney Swifts, bats, etc.), pollinators that feed in fields and field edges, and grassland-nesting species in the Connecticut River Valley. If we are successful in securing funds, we hope to collaborate with the Conte Refuge in 2021 to deploy VHF nanotags on breeding Barn Swallows to learn more about the locations of important feeding areas with presumably healthy insect populations. This work would also include education activities, working with private landowners to maximize the conservation benefits associated with their farms, as well as conducting inventories of declining birds and other taxa. We’ll post more information about these efforts in future blogs.

Bobolinks Are Thriving On Protected Fields

The bird surveys of the fields protected by The Bobolink Project are just about done, and the Bobolinks are currently busy tending to their young. Our partners in Vermont, where the majority of the Bobolink Project fields are, report that there are a lot of fledglings on the fields and that overall numbers are looking good this year (more on this in September).

This year, thanks to our awesome donors, The Bobolink Project was able to protect 995 acres of grassland habitat in Vermont, Massachusetts, Maine, and New York—the most we’ve ever protected in a single year! The 22 landowners who were accepted into the program will receive financial compensation (at the rate of $50/acre) in August for delaying mowing on their fields and therefore allowing these birds to successfully raise their young. Our Bobolink Project landowners care about grassland birds, but need a little financial help to do so. Hay cut early in the season is more valuable than that cut later in the summer and The Bobolink Project compensation helps make up the difference.

Protecting More Than Bobolinks

The program is called “The Bobolink Project” because Bobolinks are more widespread and easier to see than other birds that nest in grasslands. Many other species also benefit from the protection of grassland habitat through the program. Song Sparrows, Grasshopper Sparrows, and others have been spotted nesting on the fields. Excitingly, a Sedge Wren was found singing on one of the Bobolink Project fields this summer. Sedge Wrens are endangered in New England and a rare sight.

Help Us Permanently Protect Grassland Birds At Patten Hill

In addition to running The Bobolink Project, Mass Audubon also permanently protects natural land for wildlife and people. Mass Audubon has the opportunity to protect 67 acres at Patten Hill, which is adjacent to Mass Audubon’s High Ledges Wildlife Sanctuary in Shelburne Falls, MA. Of those 67 acres, 40 acres are grassland habitat with nesting Bobolinks. Protecting the property will also result in more than 1,000 acres of connected protected natural land.

Mass Audubon needs to raise $442,000 to acquire Patten Hill and we’re almost halfway there. Give today to help us protect this habitat for birds and other wildlife.

Barn Swallows Successfully Return to Nest at Conte National Fish and Wildlife Refuge

Barn Swallows build their nests out of mud often on the eaves, rafters, and cross beams of barns, stables, and sheds.

Last summer, Mass Audubon’s Director of Bird Conservation, Jon Atwood, collaborated with Andy French, project leader at the Silvio O. Conte National Fish and Wildlife Refuge, to study Barn Swallows that were nesting in an aging horse stable destined for demolition during the non-breeding season. Approximately 40 pairs of swallows nested in the stable during 2019; an additional 4-7 pairs nested in an adjacent building, known as the Boat House, which the US Fish and Wildlife Service (USFWS) planned to set aside as a more long-term Barn Swallow nesting site and storage area. The aging horse stable was eventually demolished after the resident swallows had migrated to their South American wintering grounds.

The Barn Swallows are back!

We have good news to report! As hoped, the majority of swallows that nested in the stable in 2019 have returned and set up housekeeping in the Boat House. As of June 16 (still relatively early in the breeding season), 30 pairs were actively nesting in the Boat House, and four additional pairs had established nests in nearby artificial structures built for this purpose.

Jon Atwood removes a captured Barn Swallow from a mist net for banding.

Last year Jon banded many (but not all) of the Barn Swallow adults so that we could tell if they returned to the site in future years. Of 51 birds that have been captured using mist nets in the Boat House in 2020, 22 (43%) had been banded as adults in 2019 in the stable. In other studies, researchers have found that return rates of breeding swallows to undisturbed nesting sites have ranged from 20% in Oklahoma to 42% in New York. Although most Barn Swallows do not return to where they were hatched, we have even captured 2 individuals that hatched from nests that were located last year in the horse stable.

A new kiosk gives an up close look at the birds

USFWS has placed video cameras in the Boat House, and visitors can watch the nesting swallows feed their young from an observation kiosk located near the start of the 1.2 mile long universally-accessible Fort River Birding Trail. Visitors may also be greeted by the families of Tree Swallows and Barn Swallows that are also nesting in the kiosk. The kiosk will eventually house a professionally-designed and fabricated exhibit with information about aerial insectivores.

This success will lead to other successes going forward

Not only does this success story provide a happy ending to the difficult management debate that swirled around the U.S. Fish and Wildlife Service’s decision to remove the horse stable, but these efforts have also paved the way for future conservation actions that can be applied to other situations. Aging barns occupied by Barn Swallows are a common feature in New England’s historically agricultural landscape, and sometimes these structures cannot be saved. Through the experience at Conte Refuge we have learned important lessons about how to attract and relocate Barn Swallows into alternative structures where they can be protected if occupied barns need to be removed.

We’ll keep you posted as the season progresses.

Conservation Success Stories: The Osprey

Ospreys are on the rebound after a troubled past. Despite a history of pesticide poisoning, persecution, and population declines, Ospreys have returned as one of the most abundant raptors of the coast. Today, the Osprey’s story stands as a testimony to the power of scientifically-informed environmental activism.

DDT: A Silent Threat

Osprey numbers crashed dramatically following the widespread use of DDT, a pesticide deployed across America in the 1940s. While previous decades saw Ospreys hunted as “pests” and their wetland habitats drained for development, the introduction of DDT all but rang the death knell for the entire US Osprey population.

Nobody realized it at the time, but DDT builds up in animals’ body tissue, and persists in the environment years after being sprayed on farm fields. This spelled trouble for birds of prey: while DDT spraying rarely poisons adult birds to death, it destroys the structure of raptors’ eggshells, preventing them from reproducing.

As a result, Ospreys declined by over 90% between 1950 and 1970. When the now-famous environmentalist Rachel Carson finally named DDT as the culprit in her book Silent Spring, the discovery ignited a movement. A coalition of the National and Massachusetts Audubon societies, as well as local land trusts and nationwide advocacy groups, intervened on behalf of all species threatened by DDT. They sued the Environmental Protection Agency to ban the pesticide—and won.

A few decades later, Ospreys are almost back to their pre-DDT abundance.

A Place To Nest

The DDT ban eliminated a significant threat to Ospreys, but the bird didn’t immediately bounce back. Even in places with clean water and plenty of fish, Osprey numbers are naturally limited by the number of appropriate nest sites. They normally require a tall, dead tree at the edge of a marsh, but lacking standing trees in the open, they settle for utility poles or other problematic locations.

Artificial nest platforms are one solution. In addition to keeping Osprey nests away from telephone wires and buildings, nest platforms increase the number of Ospreys any wetland can support. With wetland edge habitats constantly losing ground to development, it’s critical to maximize the number of Osprey nesting in appropriate wetlands.

Mass Audubon Continues To Support Ospreys

Mass Audubon’s South Coast Osprey Project maintains about 100 Osprey nest platforms. The project also monitors and records data on the Osprey population, including banding and tagging several birds, and tracking their movements. The data never fails to yield exciting results— whether demonstrating Ospreys’ reliance on the spring herring migration for food, or revealing variability in Ospreys’ choice of wintering grounds (South Shore birds end up in places as far away from one another as Cuba and Bolivia).

If you love Ospreys as much as we do, consider sponsoring a nest platform!
