The Bobolink Project 2019: End of Season Report

© Allan Strong

The Bobolinks are making their way south to their wintering home in South America and there are more Bobolinks doing so thanks to The Bobolink Project. THANK YOU to all of our donors and participating landowners for making 2019 another successful year for Bobolinks!

The numbers are in!

This year The Bobolink project protected 928 acres of hayfields for grassland birds. On these fields we estimated that there were 227 Bobolink pairs and 633 young fledged. Those estimated 633 fledglings would not have survived without the help of The Bobolink Project!

For those of you familiar with last year’s numbers, this year’s numbers don’t sound nearly as good. Bobolink numbers were down (633 fledglings this year vs. 1,027 fledglings in 2018) despite us protecting about the same number of acres. Why? The answer is, we don’t really know! But here are some possible explanations to consider:

  • Perhaps this observed decline is not real. Each year we base our calculation of fledgling number on the number of breeding males which are estimated at the start of the nesting season. This is a difficult number to collect, since we always prefer to spend our Bobolink Project donations on enrolling more acres rather than hiring field crews to do careful censuses of participating fields. In similar year-to-year bird monitoring efforts, for example the USGS Breeding Bird Survey, numerical estimates are typically averaged across several years in order to calculate trends, rather than making comparisons from one year to the next.
  • However, 11 of the farms enrolled this year were also enrolled in 2018, so maybe there was a decline. There are several possible causes of decline:
    • Fewer birds returned from their South American wintering grounds.
    • Unusually wet spring weather may have delayed the onset of nesting, thus causing lower estimates of breeding birds.
    • The wet spring weather may have improved nesting conditions throughout the region, causing some of the birds that previously nested on Bobolink Project fields to nest on a different field.
    • Fields could be degrading due to weather conditions or other factors, making them less suitable for the birds.

Because of these—and other—uncertainties, the most reliable metric to us in evaluating The Bobolink Project’s success is the number of acres protected. This number increased significantly between 2017 and 2018 and held steady this year.

And don’t forget—The Bobolink Project protected fields are home to other birds too. Savannah Sparrows, Eastern Meadowlarks, and other birds were also seen on the fields.

2020 season will be here before we know it

The 2020 season may seem a long way off, but the sooner we can start collecting donations, the better. This project is only as successful as the amount of donations it receives from people like you. Donate now >

Meadowlark Project 2019: Birding for Conservation

Now in its third year, the Eastern Meadowlark Project is a great way to support bird conservation by simply going birding.

By checking for meadowlarks at a list of sites and entering observations on our project webpage, citizen scientists help piece together the reasons for this species’ decline.

We know that meadowlarks are in trouble. Between 1974-2011, meadowlarks disappeared from over 78% of their Massachusetts breeding sites, according to Mass Audubon’s Breeding Bird Atlas.  This decline is only partially explained by meadowlarks’ habitat requirements.

Our 2018 volunteers found meadowlarks at just 3 sites out of over 100 protected grasslands across the state. While meadowlarks do persist at a handful of known agricultural sites outside our survey areas, these results suggested they aren’t using all of the habitat ostensibly available to them. So, while we know habitat loss is a major factor, we also know that it’s not the only part of the meadowlark decline equation.

Our next step is to check sites where meadowlarks were historically seen–including areas that might not be textbook habitat for them. This year, surveys will take place at sites where Eastern Meadowlarks were spotted during the past two Breeding Bird Atlases (1974-1979 and 2007-2011). This will help us both establish where meadowlarks have disappeared from their historical range, and what kinds of habitats meadowlarks are using aside from natural grasslands.

Go Birding—For Science!

First, visit our Anecdata webpage to select sites where you can help look for meadowlarks.  You’ll need to create an account by clicking “register” in the top right corner and creating a username and password. Then, return to the meadowlark project page and click “join project” (just under the photo of the meadowlark). To view a map of sites, click on “add an observation,” then click “use a hotspot” in the upper left, and then click “map.”  Finally, be sure to sign up for the hotspots you choose on the signup list mentioned in the project description!

To keep our data uniform and reliable, a volunteer should survey a site three times between April 10 and June 15, for any 10-minute period between 5:00 am and 9:30 am.  Not all of our sites may have meadowlarks, and that’s perfectly fine— knowing where they aren’t, and figuring out why, is just important to us as knowing where they are.

Thanks for helping us help grassland birds– and good luck finding meadowlarks!

1,027 Bobolink Fledglings Saved This Summer

By The Numbers: The 2018 Bobolink Project

We’re tallying up the results of this year’s Bobolink Project, and the numbers look great! The Project protected 932 acres of nesting habitat, up from 512 acres in 2016 (which was the project’s first year at Mass Audubon). Field surveys showed 368 pairs of Bobolinks on participating farmers’ land. Since Bobolinks fledge an average of 2.79 chicks every season, this translates to saving an estimated 1,027 Bobolinks—many of which may return to nest again next year!

How it Works

Bobolinks rely on grasslands to breed, and often find that hayfields work just as well. Until the mid-20th century, many hayfields were mowed in late summer, weeks after Bobolink chicks had left the nest. Now, high demand for livestock feed means that farmers are mowing earlier and earlier; early-cut hay is richer in protein and more valuable. Sadly, this means that many Bobolink nestlings end up under the mower.

Every year, Mass Audubon offers farmers compensation for waiting to mow their hayfields until after nesting season. This model has so far proved effective: plenty of farmers would rather not mow over active bird nests, but need their hayfields to produce some source of income. Mass Audubon uses donations to cover these farmers’ losses from delaying mowing, keeping their farms economically viable while protecting grassland birds.

Next Year’s Goals

Even with increased donations, the number of interested farmers is outpacing available funds. This year, we had enough funds to protect two thirds of project applicants’ land. We also had to leave an additional 492 acres of Bobolink habitat on the table. Sadly, this funding gap meant that most fledglings on the unprotected acreage didn’t make it.

While it may not be possible to prevent every single agriculture-related Bobolink death across the region, it is painful to have to turn away farmers who want to partner with us to protect birds.

If you’d like to help us protect even more acres and Bobolinks next year, please donate here!

Can You Help Us Find Meadowlarks?

The Eastern Meadowlark is in serious decline in our state and nationwide. To understand what we can do to turn this around, we’re enlisting the help of volunteer birders and citizen scientists. By entering observations on our project webpage, anyone can contribute to conservation efforts for this iconic species.

Meadowlarks disappeared from over 78% of their Massachusetts breeding sites since 1979, according to Mass Audubon’s Breeding Bird Atlas.  This decline is only partially explained by meadowlarks’ habitat requirements.

Conservation scientists know that meadowlarks need a certain kind of grassland habitat— vegetation that’s short, but not too short; fields over 20 acres with no standing trees. These days, however, suitable fields that once rang with meadowlark song are quiet and still.

Agricultural intensification certainly plays a role: 95% of Eastern Meadowlarks nest on private land. Fallow farm fields are harder to come by and pesticide application increases apace; more and more pastures and grassy fields are either overgrazed or developed. But this is only part of the story, and it’s up to us to figure out the rest.

Go Birding—For Science!

All you need to do is visit our Anecdata webpage and select sites where you can help look for meadowlarks.  To view a map of sites, click on “add an observation,” then click “use a hotspot” in the upper left, and then click “map.”  Be sure to sign up for the hotspots you choose on the signup list mentioned in the project description!

To keep our data uniform and reliable, a volunteer should survey a site three times between April 20 and June 15, for any ten-minute period between 5:30AM and 9:30AM.  Not all of our sites may have meadowlarks, and that’s perfectly fine— knowing where they aren’t, and figuring out why, is just important to us as knowing where they are.

These surveys can be great fun. It’s no longer every day that casual observers see the bold pattern and lemon-yellow blaze of a meadowlark standing, flaglike, atop a fencepost. Fewer and fewer people recognize their ringing whistle. There’s always some pride in finding an uncommon bird. But the joy of a meadowlark sighting can also be colored by nostalgia, whether for the historical abundance of grassland birds, or the broader decline of pastoral landscapes.   

The great thing is, we can do something about it.

A Final Push For Bobolinks In 2018

The Bobolink Project is almost ready to go! With one week left for donations, we’re just $2000 away from protecting 1,000 acres of grassland bird habitat this year. That would be nearly twice as many acres as when the project started! With this year’s increase in farmers applying to protect habitat on their land, we need to ask for more help to accept as many applicants as we can.

The Bobolink Project works through a reverse auction, meaning farmers name the lowest per-acre price they’ll accept in exchange for a delay in mowing their fields. We select the lowest bids and work our way up the list, making agreements with more farms until we reach the limit of our Bobolink donations for the year.

Delaying hayfield mowing is a tried-and-true way of protecting Bobolinks. Hayfields provide an excellent surrogate for the tall grassland Bobolinks require to nest- such an excellent surrogate that Bobolinks can rarely differentiate wild grassland from agricultural hayfields. But when fields are mown before the end of nesting season, eggs and nestlings are destroyed during the harvest. Unfortunately, early-season hay is protein-rich and valuable, and some working farms cannot afford to delay mowing and drive down the value of their hay.

That’s where we come in—we use donations to cover the cost of mowing later, essentially buying the birds time to raise their young and move out.

Every donation directly protects acreage of fields and their resident Bobolinks. Please help us make it to our goal of 1,000 acres this year!

Where Do Woodcocks Go In The Snow?

When winter weather drags on into late March, our earliest spring migrants still show up on schedule!  Birders often hear the sharp, reedy “peent!” of American Woodcocks in mild weather amid other spring sounds, like the clamor of wood frogs and spring peepers. Hearing them calling from fields covered in several feet of snow can seem incongruous. So how does lingering snow affect these enigmatic birds’ ability to find food?

Beak Superpowers

Woodcocks find insects by probing underground with their beaks. The tips of their beaks pack a bundle of highly sensitive nerves, which they use to pick up on vibrations from insects moving in the soil.

The tip of their beak can also flex open while the rest of it stays closed, allowing woodcocks to delicately pick up food without having to pry their whole bill open underground. The ability to open just the end of the beak is called distal rhyncokinesis  (rine-co-kin-EE-sis), or simply rhycokinesis  when discussing beak flexibility more generally. It’s a trait shared by many members of the sandpiper family, woodcocks included.


This photo only partially shows how flexible the tip of a woodcock bill is– underground,  they can close the lower two thirds and move just the outer third. (Photo: Will Freedberg) 

 

With such particular feeding habits, spring snowstorms might seem to spell trouble for these ground-dwelling insect-eaters. In particular, 2018 has seen a spate of nor’easters barreling through New England, dumping foot after foot upon snow.

Snowed-in Woodcocks Seek Open Ground

Woodcocks can often feed successfully through a shallow layer of snow, but only if the ground is not frozen through. If the ground has already thawed, a covering of snow will in fact keep the ground from freezing fully again, if temperatures return below freezing.

But March 2018 has seen snowpack deeper than a woodcock’s bill is long, even when the ground hasn’t been frozen solid. In years like this, woodcocks feed near any natural features that keep snow off the ground—along the banks of streams and flowing water, or under coniferous trees that partially shelter the ground from snow.

Birders in the know will look for them in these areas, and are careful not to scare or flush these easily-stressed birds. Their flight displays have continued along the edges of fields so far regardless of snow cover, and should keep going into April.

Another successful year for The Bobolink Project

We are proud to share a final report on what The Bobolink Project accomplished during the summer of 2017. But before we share the results, we first and foremost thank our donors. With their financial support, conservation interest, and promotional efforts, The Bobolink Project would not exist. This is very much a grassroots conservation effort—pun intended—and we are deeply appreciative of our donors’ support.

We also thank the farmers who applied to and participated in the project. Without them the habitat for grassland birds would not exist. We are glad that they are conscious of the birds on their fields and that they are willing to participate in a solution that allows them to grow a “crop” of grassland birds without compromising their financial stability.

Donations and Farms Enrolled

In the months leading up to the 2017 field season, we raised just over $38,000 to support the project’s objectives, and 99% of this donation pool was given directly to the participating farmers. Based on the fixed-price reverse auction, the final bid that was accepted from the farmers was $60/acre.

With this financial support we were able to enroll about 630 acres distributed among 17 farms—13 located in Vermont, two in Massachusetts, one in New Hampshire, and one in New York.

Successful Breeding Pairs and Fledglings

The project state coordinators surveyed the fields this summer to measure the success of the program for grassland birds. They estimated that there were about 294 pairs of Bobolinks on the enrolled fields. Using what we think is a conservative estimate of 2.79 fledglings per breeding pair, we estimate that 820 Bobolink young were produced as a result of the project’s 2017 efforts.

The number of fledglings nearly doubled from 2016 to 2017 even though the amount of protected acreage increased by about 20%. The huge increase in fledgling numbers is due in large part to one of the participating farms in particular, which consisted of 146 acres with many nesting Bobolinks.

The 2017 breeding season was also especially wet in many parts of the northeast. Increased amounts of rain typically means more invertebrates (e.g., insects) for Bobolinks to eat. This enhancement of breeding conditions could have influenced the higher number of Bobolink pairs and fledglings estimated this year.

What We Left On the Table

Another important aspect of this project concerns what we were unable to accomplish.

In 2017, we had to reject applications from 19 farmers who had submitted bids that exceeded what we were able to support from our donation pool. In other words, about 615 acres of offered habitat was lost because we needed more donations.

Of course, it’s wonderful that we succeeded in protecting 634 acres of grassland bird habitat! But the fact that we had to “leave on the table” a total of 615 acres—land that otherwise might have been protected—is a sobering thought. Remember, the more donations we collect, the more land we can protect from haying. We hope this reminder motivates new and previous donors alike to support the Bobolink Project in 2018.

In fact, contributions toward next year’s efforts can be made now—even while the birds themselves are busily heading toward South America! It’s never too early to make a donation, and your gift will be set aside for the 2018 nesting season.

The Bobolink Project: 2017 season update

 

Male Bobolink © Allan Strong

The Bobolinks are arriving in New England and we’re finalizing the contracts with our participating Bobolink Project farmers. Thanks to the generosity of our Bobolink Project donors, we can protect over 630 acres of farmland this year! In return for some compensation, the Bobolink Project farmers will delay mowing on their hay fields until the young grassland birds have had time to fledge.

As in past years, we had more acres submitted into the project than we could cover with the available pool of donations. This year, we received 40 applications from farmers in Vermont, Massachusetts, New Hampshire, Maine, and New York—but our donation pool, as of April 1st (our deadline for donations), could cover only 17 of the farmers’ fields. This may sound disappointing, but we are able to cover 20% more acres this year at a lower per acre price of $60 (vs. $75 last year).

We are glad that the project is continuing to grow and look forward to welcoming grassland birds to fields enrolled in the program this summer and sharing our results with you. Keep up to date with The Bobolink Project by signing up to the mail-list or follow us on Facebook.

The Bobolink Project donations are accepted all year. The 2018 donation pool is already growing: since April 1st we have received over $8,000 in donations that will be saved for next year. Donate now to help us protect more acres and birds next year.

 

Check out the updated Bobolink Project website!

Hi all,

We are pleased to announce that we have finished updating our website for the coming 2017 Bobolink Project season. Check out the new information at www.bobolinkproject.com. The farmer applications are live and donations are very welcome.

We will be accepting farmer applications until March 20.

  • IMPORTANT: We have changed some of the criteria for eligible farms and clarified a few other things so we highly recommend that you thoroughly read through the For Farmers page.

We also encourage donors to donate before April 1 when we will begin selecting farms for the program. The reason why only donations before April 1, 2017 will be applied to the 2017 season is because the number of farms and which farms we accept into the program depend wholly on how many donations we have pooled up to that deciding date when we start creating the contracts. Any donations that come in after April 1 will be saved for the following 2018 season.

Contact us at bobolinkproject@massaudubon.org if you have any questions.

We are looking forward to a new season of The Bobolink Project!

 

The Bobolink Project 2017 Season Is Ramping Up

The Bobolinks are starting to plan their trip back north and we’re busily working to welcome them home by ensuring we conserve as many acres of grassland habitat as we can.

As many of you already know, The Bobolink Project is an innovative solution to a complicated problem. We use donated dollars to give farmers the financial assistance they need to protect grassland birds on their hay fields. We were thrilled with the success of the project under its new leadership of Mass Audubon and partners in 2016, and know that we can do even better this year!

Last year we raised about $42,000 that enabled us to help farmers protect over 500 acres. Based on past data, we estimate that our Bobolinks raised 450 young on those acres. That’s 450 more Bobolinks than would likely have existed had The Bobolink Project not been in existence! We thank you for your help in that.

The more donations The Bobolink Project receives, the greater the number of Bobolinks and other grassland birds we can protect and help fledge. Only with your help can we use this innovative solution to directly and effectively conserve grassland birds.

Please make a donation before April 1, when we will start enrolling the farms in the program.
