Tropical Storm Isaias doused Massachusetts in Sooty Terns—and one is still around

Tropical Storm Isaias arrived in Massachusetts on August 4, 2020, pushing heavy wind and rain through the Berkshires in the early evening before continuing northward. The storm also brought a slew of rare seabirds into the state, with sightings of at least 34 Sooty Terns, 2 Brown Boobies, a Franklin’s Gull, and a handful of other rarities on inland lakes as well as on the coast. This event was part of a rare but regular pattern of vagrant birds associated with hurricanes and tropical storms.

All hurricanes and strong tropical storms in Massachusetts have the potential to carry vagrant birds with them. Generally, the best sightings come in the wake of storms that spend time offshore over the Gulf Stream, before weakening or dissipating over southern New England.

But storms that hug the coast from the southwest can also carry exciting birds. Most storms are big enough that even if their center sits over the New Jersey or New York coast, violent southerly winds sweep from the Gulf Stream into southern New England. This was certainly the case with Isaias, as seen in the wind speed graphic below.

From here, Isaias tacked directly inland through the Berkshires, making it a great candidate for delivering pelagic species to large inland lakes. Indeed, while there were some reports of strong pelagic birding from coastal sites like Gooseberry Neck in Westport, there were equally exciting reports from Wachusett Reservoir, Quabbin Reservoir, and even smaller lakes in the Berkshires. Sooty Terns, Phalaropes, Jaegers, and shorebirds dropped onto many large bodies of water throughout the state.

Stronger storms in the past have produced even more spectacular results. In 2011, Hurricane Irene brought an incredible variety of seabirds into Connecticut and Massachusetts. and resulted in at least one eBird checklist from Quabbin Reservoir that reported a Sooty Tern, an incredible White-tailed Tropicbird, a Leach’s Storm-Petrel, and more.

Often, storm-blown birds arrive at inland sites in bad shape. Many perish, and some return to their offshore or coastal habitats. Very few stick around for several days.

Remarkably, one Sooty Tern that appeared during Isaias has hung around on Wachusett Reservoir. The bird was reported feeding actively as of August 13th, more than a week after the storm, probably taking advantage of the reservoir’s abundant smelt. Smelt resemble Sooty Terns’ favored marine baitfish—mostly clupeiformes—in the subtropical Atlantic. This makes it the longest-lingering storm-driven Sooty Tern in Massachusetts, and quite possibly, in New England. It may leave any day now, and in fact, it’s likely to depart sooner rather than later. If you haven’t seen it yet, it’s worth looking for!

Warmer springs mean birds breed earlier—but also on tighter schedules

Climate change is not only shifting the breeding season for northern forest birds, but it is also shortening it for some, according to a 43-year study co-authored by a UMass Amherst ecologist.

The study examined 73 species of boreal birds in Finland, but the results reflect patterns in bird observations from other parts of the world as well.

Ecologists have shown how climate change effects birds’ ranges, as well as the timing of some of the key phases in their lives. For background, many birds of the Northeastern US will experience range shifts (many of which are already underway) as global temperatures increase, according to models in Mass Audubon’s 2017 State of the Birds report. Climate change tends to affect birds’ ranges by moving their habitat or food supply further north or to higher elevations. While birds are somewhat temperature-sensitive, the plants and insects they rely on tend to respond much more sharply to changing conditions, bringing the birds with them.

Other long-term studies have shown that seasonal peaks in insect abundance no longer line up with the arrival of migratory birds that feed on them— and that other factors, like weather patterns, make it difficult for birds to change their schedules accordingly.

But the new 43-year study from Finland is the first to look at the duration of the breeding period from start to end. Around a third of species examined by researchers showed some shortening of their breeding period. Most of the study species started or ended breeding slightly earlier.

At first glance, a reader might worry about the third of birds that breed on an accelerated schedule, and assume that the other two-thirds of species were unaffected. Indeed, the study noted that shorter breeding periods increased competition among individuals of a species— for example, by synchronizing the times that adults were arriving or that chicks were hatching and leaving the nest.

But that’s only part of the problem. In fact, the species that showed no indication of changing their breeding schedule may be cause for greater conservation concern. Just because only some birds are adapting to a shorter “ideal” breeding period doesn’t mean that other birds aren’t feeling the squeeze; other species could be failing to adapt to changing conditions, even if they face the same challenges. The study’s authors pointed out that most of the birds with a curtailed breeding season are either short-distance migrants or year-round residents. Long-distance migrants— whose breeding schedule showed fewer changes— are less able to adjust their migration and breeding dates because of constraints at stopover sites or wintering areas.

Take a Climate Pledge

Climate change affects so much more than birds. Everything from pollinators that maintain food crops, to shellfish and ocean ecosystems, to the cities we live in are facing new climate-related threats.

We can help when we come together to act on climate! It’s easy to reduce your personal carbon footprint by taking one of our climate pledges to commit to greener transportation, sustainable eating habits, or easing pressure on the energy grid when demand is highest. While advocacy, activism, and systemic change are also key to stopping climate change, adjusting our consumption habits is an excellent first step to protect the planet we love.  

Our Sanctuaries Need Your eBird Reports

As we begin to again safely visit our wonderful system of Mass Audubon sanctuaries, this post is a reminder of how you can contribute to our knowledge of birds at these sites. Mass Audubon uses eBird data as part of bird monitoring and inventory efforts, and visitors’ observations help demonstrate how birds use the places we protect. The more information we have, the more we can bolster bird populations amid changing climate conditions and surrounding land use. Your observations help us help birds!

Mass Audubon has updated guidelines for submitting sanctuary observations to eBird, some of which may be new even for experienced eBirders. Most importantly, we ask that, unless you are contributing to a specific project, eBirders only submit sightings under the most general eBird hotspot for each sanctuary, instead of using latitude/longitude coordinates or specific locations within each sanctuary.

Loons Return to Plymouth County after a Century-Long Absence

Fast on the heels of Bald Eagles’ exciting return to Cape Cod, another iconic species of the north has recolonized Southeastern Massachusetts after more than a hundred years’ hiatus. This summer, Common Loons are raising chicks in Plymouth County for the first time since at least 1872.

It started with an oil spill

Loons used to be common in some of the deep, clear lakes of Plymouth County until the 19th century, when sport hunting and state-sponsored extermination programs removed them from the state entirely. While loons that breed in New Hampshire and Maine spend winters off the Massachusetts coast, it wasn’t until 1975 that they started nesting here again. In fact, Massachusetts is the only state where loons have returned of their own volition, and they now number over 100 birds—but only in the north-central and western parts of the state.

Strong, proactive environmental laws are enabling loons’ renewal to this part of their original range. The male of the Plymouth County pair arrived as part of a reintroduction program, funded by a legal settlement over a Buzzard’s Bay oil spill.

In 2003, the population of overwintering loons in Buzzards Bay took a hit when an oil barge spilled 100,000 gallons of oil into the water after striking a rock. The spill killed over 1,000 marine birds (the total loss, accounting for those birds’ future contributions to their populations, is closer to 20,000 birds). 

Under the Oil Pollution Act of 1990, the barge company had to pay to clean up its mess. (At the time, the Migratory Bird Treaty Act also required that companies pay to restore any birds they accidentally killed, whether or not an oil spill was involved). Some of the funds went towards habitat protection, lead fishing tackle cleanups, and artificial nest sites in areas with existing populations. But there’s no easy way to quickly replace 530 Common Loons, especially when it’s not clear which breeding areas the dead birds came from.

So, the remainder of the funds went towards facilitating loons’ return to places they had historically occupied by translocating “excess” birds from upstate New York and Maine. When loons have two chicks, one often outcompetes the other, which is less likely to survive—making the second chick a great candidate for captive rearing.

Giving loons a head start

Local loon reintroduction efforts formally began in 2015, when the Biodiversity Research Institute began raising loon chicks in captivity in partnership with state wildlife agencies. For the next few years, they managed to release around eight young-adult loons annually into unoccupied, good-quality habitat in Massachusetts.

The project’s success would only become clear a few years later. Young loons don’t breed until they reach several years of age, spending at least the first three years of their life at sea. The marine areas they use as juveniles continue to be their wintering grounds as lake-breeding adults.

While one of the (now fully-grown) male loons has returned to the Plymouth County lake where it was raised for the past couple of years, it was joined by a fully wild female in the spring of 2020. Their chick— the first of what will hopefully be many to come out of the translocation effort—was spotted a few weeks later.

Strong conservation laws yield results

In this case, loons’ reintroduction into southeastern Massachusetts was part of a larger vision for restoring public resources—from fisheries, to swimming beaches, to migratory birds—after they were accidentally damaged by a private company.

But were the damage to bird populations not caused by an oil spill or other pollution that affected people’s health, only the MBTA could have been used as a legal tool to require that a company make amends. Now, that framework is gone—and the current administration’s decision may soon become difficult to overturn

Birders have already observed several other loons from the reintroduction project at different sites across eastern Massachusetts. If you see a loon with a leg band, or on fresh water inside of route 495, let us know in the comments!

Black Birders Week: A Step Towards a More Inclusive Birding and Science Community

May 31 to June 5, 2020 marked the first ever Black Birders Week, a five-day virtual event to raise awareness and highlight the need for action surrounding the racism and discrimination Black individuals face in nature spaces. Unlike their white counterparts, black individuals face additional challenges that can prevent full enjoyment of the outdoors; challenges that are rooted in systemic and historical racism that manifests today in unconscious and conscious biases against black individuals. These challenges often result in low representations or exclusion of people of color in nature and outdoor activities. Black Birders Week sparked a national discussion and the organizers, a group called the BlackAFinSTEM collective, hope that the result of this increased awareness and understanding of the black perspective will lead to a normalization of people of color in birding, nature, and science. 

The idea for the five-day-long virtual event was conceived in response to the alarming racist incident recorded in Central Park between Christian Cooper, an avid Black birdwatcher and member of New York City Audubon board of directors, and a white woman who was weaponizing race as a scare tactic against Cooper.  Seeing the national response, organizers saw this as an opportunity to acknowledge that the experience of Christian Cooper was not uncommon for Black people in nature, and although racism manifests itself in various ways, there are things everyone can do to support a more diverse and welcoming outdoor community for all. 

Each day of the event had a different online experience. Below are posts from Twitter and Facebook that highlights the week’s activities and participants experience.  

Day 1: #BlackInNature celebrated Black nature enthusiasts around the world debunking the stereotype that black people do not enjoy nature. 

Day 2: The #PostaBird challenge asked people to share their favorite bird photos and facts. 

https://twitter.com/Bashir_1501/status/1267464977763504134

Day 3: #AskABlackBirder featured a two-hour Q&A with Black Birders   

Day 4: The #BirdingWhileBlack livestream discussions offered a space for Black birders, including Dr. J. Drew Lanham, Jason and Jeffrey Ward, Corina Newsome, and Kassandra Ford, to share their love for birds and their experiences—both positive and negative—being and working in natural spaces. (view Session 1 and Session 2).  

Day 5: #BlackWomenWhoBird increased visibility and representation. 

Key takeaway from Black Birders Week

Birding and Nature are for Everyone, Everywhere 

Birding and being in nature are typically thought to be rejuvenating, fun, relaxing, and peaceful, but people of color cannot always fully enjoy these feelings because of an underlying sense of “otherness” or not belonging. In some cases, they experience racism both blatant and subtle. The livestream sessions with Black birders were particularly eye-opening because each and every person on the stream could recount a time where they: 

  • Felt unsafe going to a certain area (or even an entire state) to bird because they feared someone would report a “suspicious” black person or their safety would be otherwise threatened because of the color of their skin. 
  • Felt out of place in a group of other birdwatchers because they were the only person of color and the others in the group seemed amazed by them being there. 
  • Experienced outright racism from police or other individuals. 
  • Made sure to be obvious that they were birdwatching by raising their binoculars or wearing nerdy bird-themed clothes to reduce suspicion. 

It is unacceptable that this is a reality for so many bird and nature enthusiasts. Birds and nature are for everyone to enjoy and study regardless of the color of their skin.

Bobolinks Are Thriving On Protected Fields

A Bobolink male and female with food for their nestlings on a field protected by The Bobolink Project (video by Allan Strong, UVM).

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.

Historic Warbler Fallout and Record Bird-a-thon Participation

Warblers seemed to rain from the sky during Bird-a-thon 2020 after unusual weather doused Massachusetts in migrants. Birder participation more than doubled, too, but not because conditions predicted a massive influx of birds. Instead, it seems that more beginners were brought in by a family-friendly approach and a focus on birding from home.

Birds were everywhere

As the sun rose on the Outer Cape on May 16th, thousands of birds gathered in the dunes after being blown in from the southwest and grounded by rain. The subsequent dawn flight became the subject of several expert articles, including an in-depth analysis of the conditions by ornithology professor Sean Williams. Some eBird checklists recorded over 100 Bay-breasted and Cape May Warblers, plus dozens of individuals of other uncommon migrants like White-crowned and Lincoln’s Sparrows.

Inland, the action was almost as good, with several Bird-a-thon-ers in dense suburbs and towns setting personal records for their yards. Nonstop north winds had held birds back for nearly two weeks, and when the wind finally turned southwest, restless migrants pushed ahead despite the storms. Nearly everything showed up at once; yard reports of Cerulean Warblers, Bay-breasted Warblers, and Bobolinks highlighted the strength of the previous night’s migration.

“Fallout” may be an overused term– but this was real

The word “fallout” often gets misapplied to any day with really good migration. In reality, even in the loosest sense, this word refers to exhausted migrants that land in adverse weather. In the strict sense, it describes a stream of migrants that are knocked down by fast-moving storms, landing en masse when they meet the edge of the weather front.

In this case, adverse weather formed well before nightfall, but the long-delayed migrants pushed ahead anyway—there was no “knockdown” effect from the edge of a front, but the wind and rain did exhaust many birds that were blown east into Massachusetts. So, yes, this was a fallout, loosely speaking—and a uniquely great birding day by any stretch of the imagination.

New birders drove up participation

A normally competitive endeavor, this year’s Bird-a-thon focused on participation.The team cap was lifted, and new activities were made up to engage kids and non-bird enthusiasts in earning points for their team, like inventing silly bird names and creating bird art.  With a stay-at-home order driving a surge in interest in birding, it was important to welcome new enthusiasts to the fold– and avoid encouraging birders to tear across the state in search of rare species. Subsequently, Bird-a-thon attracted 1,600 participants this year, more than double the 750 who took part in 2019. 

Donations were up, too

As of right now, Bird-a-thon raised over $295,000 – far surpassing the $250,000 goal. Despite the current economic hardships of the coronavirus pandemic, these funds are up from the $240,000 raised last year.

The final tally

In total, Mass Audubon teams saw 242 unique species in Massachusetts. Teams were awarded points based on the number of unique bird species the team saw plus the number of nature-based activities team members completed. Drumlin Farm took first place with 992 points and a team of 230 participants (including 90 kids), earning the “Eagle Eye Award.” Second place, for the “Home Habitat Award” went to Wellfleet Bay with 537 points. The team from Ipswich River took home the award for the highest number of species seen: 206.

ACT at Home: Volunteer to Track Bird-Window Collisions at Residences

Even with most volunteer programs on hold for public health reasons, there’s still a way to participate in bird-window collision monitoring from home.

The normal format of the Avian Collision Team (ACT) will not be possible this spring. Last year, ACT involved around 40 volunteers looked for dead or injured migrants along routes through Boston. Working a couple of days each week during migration, those volunteers tallied 193 window-struck birds in total, representing nearly five dozen species.

Many volunteers, once primed to look for window strikes, also started reporting injured birds outside their homes and offices. Window strikes are indeed not only an urban issue, and houses in the suburbs or countryside play an important role. While a skyscraper kills an average of 24 birds per year, low-rises are not far behind at 22, and most single-family residences kill between 1–3. (Buildings vary, of course, and some are responsible for more than 100 collisions a year).

Feathers left behind on a glass residential window after a bird collided with it.

Residences: a silent culprit

Standalone homes are responsible for 90% of bird-window collisions. Even though sleek, all-glass facades on non-residential buildings kill many more birds on a per-building basis than the average single-family home, residences are more than 60 times as common as tall city buildings—making their collective impact even more significant.

More importantly, bird collisions are harder to detect outside of the city. Landscaping around houses conceals the bodies of window strike victims, and scavengers like raccoons and squirrels abound. Consequently, window strikes at residences are underreported.

Help us track bird-window collisions at home

Participating in this project requires less effort than a normal ACT season, since it only involves a quick daily check at one building (your home). It’s important, however, to make this a daily or near-daily routine, since there may only be one or two days out of the season when you find a bird (although there may be many more). As always, data on where window collisions are not occurring is just as important as where they are. The data from this project will help us better understand the problem and eventually develop recommendations for reducing bird kills caused by window collisions at residential structures and low-rise office buildings.

The survey period officially runs until June 2, when most migrants are settled into their breeding territory. Anyone is welcome to continue submitting data after that, though—breeding birds are nearly as likely to collide with windows as migrants.

If you want to learn how to make your home safer for birds, check out these tips. Please only put up bird-friendly products like window tapes or screens before or after the data collection period. Modifying your windows in the middle of the data collection period will make it impossible to analyze data from your building.
