FANTASTIC PRESENTATION BY CRANE BEACH ECOLOGIST JEFF DENONCOUR AT THE CAPE ANN MUSEUM

Jeff Denoncour, the Trustees of Reservations Eastern Region Ecologist, gave an outstanding and informative presentation to a packed audience Saturday afternoon. Subjects included the formation and history of Crane Beach, marsh, and dunes; the seven uniquely different ecological zones; the many species of flora and fauna that comprise the rich biodiversity at Castle Island; and the Trustees protective measures managing rare and endangered species.

Since 2010, Jeff has managed the Trustees Shorebird Protection Program at Crane Beach. Because of the very excellent shorebird management at Crane Beach, 2018 was a banner year, with 42 pairs of nesting Piping Plovers and approximately one hundred PiPl chicks fledged. Our community can learn a great deal from the success at Crane Beach in how to better manage shorebirds migrating and nesting at Cape Ann beaches.

We learned from Jeff that Crane Beach is part of a string of barrier beaches formed from sediment deposited by the outflow of the Merricmack River. Salisbury Beach is at the northern end, then Plum Island, then Crane, with Coffins and Wingaersheek at the southern end. The sand that was deposited at Salisbury Beach is the coarsest; the sand at Wingaersheek the lightest and finest as it would have more easily flowed furthest away from the mouth of the river.

Excerpt from a previous post OUTSTANDING COASTAL WATERBIRD CONSERVATION COOPERATORS MEETING! talking about Jeff and the success of the Crane Beach Trustees Piping Plover

“Readers will be interested to know that our region’s Crane Beach continues to have one of their best year’s ever. Trustees of Reservations Jeff Denoncour shared information on the latest census data from 2018 and Crane Beach has a whopping 76 fledglings, with 25 more chicks still yet to fledge. Because of the huge success at Crane Beach, the northeast region, of which we are a part, has fledged a total 136 of chicks in 2018, compared to 108 in 2017, and as I said, with more fledglings still to come! The northeast region encompasses Salisbury Beach to the Boston Harbor Islands.

Jeff noted that this year they had less predation by Great Horned Owls. Because of owl predation, several years ago the Trustees gave up on the wire exclosures and now use electric fencing extensively. The Great Horned Owls learned that the Piping Plover adults were going in and out of the exclosures and began perching on the edge of the wire, picking off the adults as they were entering and exiting the exclosure.

Crane has an excellent crew of Trustees staff monitoring the Least Terns and Piping Plovers, as well as excellent enforcement by highly trained police officers. No dogs are allowed on Crane Beach during nesting season and dogs are prevented from entering at the guarded gate. As we saw from one of the graphics presented about nesting Double-crested Cormorants, when a dog runs through a nesting area, the adults leave the nest, temporarily leaving the eggs and chicks vulnerable to predation by crows, gulls, raptors, and owls.”

CAPE ANN WILDLIFE 2018: A YEAR IN PICTURES AND STORIES Part Three: Summer

PART THREE: SUMMER

The most joyous story about Cape Ann wildlife during the summer months of 2018 is the story of the high number of Monarch butterflies and caterpillars in gardens and meadows, seen not only in strong numbers along the Massachusetts coastline, but throughout the butterfly’s breeding range–all around New England, the Great Lakes region, Midwest, and Southern Canada.

Three days after celebrating the two week milestone of our one remaining Piping Plover chick, Little Pip, he disappeared from Good Harbor Beach. It was clear there had been a bonfire in the Plover’s nesting area, and the area was overrun with dog and human tracks. The chick’s death was heartbreaking to all who had cared so tenderly, and so vigilantly, for all those many weeks.

Our Mama and Papa were driven off the beach and forced to build a nest in the parking lot because of dogs running through the nesting area. Despite these terrible odds, the Good Harbor Beach Piping Plover pair hatched four adorable, healthy chicks, in the parking lot. Without the help of Gloucester’s DPW, the Piping Plover volunteer monitors, Ken Whittaker, Greenbelt’s Dave Rimmer, and the AAC, the parking lot nest would have been destroyed.

These brave little birds are incredibly resilient, but as we have learned over the past three years, they need our help to survive. It has been shown time and time again throughout the Commonwealth (and wherever chicks are fledging), that when communities come together to monitor the Piping Plovers, educate beach goers, put in effect common sense pet ordinances, and reduce trash, the PiPl have at least a fighting chance to survive.

All four chicks were killed either by crows, gulls, dogs, or uneducated beach goers, and in each instance, these human-created issues can be remedied. Ignoring, disregarding, dismissing, or diminishing the following Piping Plover volunteer monitor recommendations for the upcoming 2019 shorebird season at Good Harbor Beach will most assuredly result in the deaths of more Piping Plover chicks.

FOUR WAYS IN WHICH WE CAN HELP THE GOOD HARBOR BEACH PIPING PLOVERS SUCCESSFULLY FLEDGE CHICKS: OUR RECOMMENDATIONS TO THE MAYOR

Not one, but at least two, healthy and very hungry North American River Otters families are dwelling at local ponds, with a total of seven kits spotted. We can thank the fact that our waterways are much cleaner, which has led to the re-establishment of Beavers, and they in turn have created ideal habitat in which these beautiful, social mammals can thrive.

Several species of herons are breeding on our fresh water ponds and the smaller islands off the Cape Ann coastline. By midsummer, the adults and juveniles are seen wading and feeding heartily at nearly every body of water of the main island.

In order to better understand and learn how and why other Massachusetts coastal communities are so much more successful at fledging chicks than is Gloucester, I spent many hours studying and following Piping Plover families with chicks at several north of Boston beaches.

In my travels, I watched Least Terns (also a threatened species) mating and courting, then a week later, discovered a singular nest with two Least Tern eggs and began following this little family, too.

Least Tern Family Life Cycle

Maine had a banner year fledging chicks, as did Cranes Beach, locally. Most exciting of all, we learned at the Massachusetts Coastal Waterbird meeting that Massachusetts is at the fore of Piping Plover recovery, and our state has had the greatest success of all in fledging chicks! This is a wonderful testament to Massachusetts Piping Plover conservation programs and the partnerships between volunteers, DCR, Mass Wildlife, the Trustees, Greenbelt, Audubon, and US Fish and Wildlife.

Monarch Madness

Friends Jan Crandall and Patti Papows allowed me to raid their gardens for caterpillars for our Cape Ann Museum Kids Saturday. The Museum staff was tremendously helpful and we had a wonderfully interested audience of both kids and adults!

In August I was contacted by the BBC and asked to help write the story about Monarchs in New England for the TV show “Autumnwatch: New England,. Through the course of writing, the producers asked if I would like to be interviewed and if footage from my forthcoming film, Beauty on the Wing, could be borrowed for the show. We filmed the episode at my friend Patti’s beautiful habitat garden in East Gloucester on the drizzliest of days, which was also the last  day of summer.

Learning to Fly!

Three days after hatching the Rosetti’s Least Tern parents moved the chicks further down the beach and deep into the roped off sanctuary. Tiny gray and white speckled fluff balls well-hidden amongst the rocky shoreline became increasingly difficult to see.

Well-camouflaged and nearly impossible to see one-week-old Least Tern chicks.

Every now and then though I would catch a glimpse and one of the best moments was watching both chicks test their wings in short little take offs. Stretching wide their wings and in little fits and bursts, the flights lasted about two- to three-feet in length, and equally as high. After witnessing the tremendous hardships the Least Tern colony at Winthrop had undergone this nesting season, I was over joyed to see at least one family hit this milestone.

STUCK BETWEEN A ROCK AND A HARD PLACE

After exploring the beach, the three-day-old Least Tern chick decided to take a short cut through the rocks to nestle under Mom. She was well-camouflaged while brooding and keeping warm and cozy her second chick.

He tried and tried to get to her, first hopping from one foot to the other,

while trying to squeeze with all his tiny might through the space between the rocks…

before tumbling backward, with legs splayed and wings all akimbo.

Quickly righting himself (with directives from Mom),

around he went the long way and had himself a good long snuggle under Mom.

While observing and thinking about tiny shorebird chicks, like Least Terns and Piping Plovers, I am continually struck by their resiliency, by their tenacity, and by their ability to prevail, despite the natural and manmade threats to their survival.

OUTSTANDING COASTAL WATERBIRD CONSERVATION COOPERATORS MEETING!

Piping Plover Chick Lift-off! – Not quite ready to fly yet, but testing his wings and airborne for a few seconds.

On Tuesday this past week my friend Deborah and I attended the Coastal Waterbird Conservation Cooperators meeting, which took place at Cape Cod Community College in Barnstable. The meeting is held annually to bring together people and organizations that are involved with population monitoring and conservation efforts on behalf of coastal waterbirds. Threatened and endangered species such as Least Terns, Piping Plovers, and American Oystercatchers are given the greatest attention, while the meeting also encompasses efforts on behalf of heron, cormorant, and egret species.

American Oystercatchers

Conservationists from all seven Massachusetts coastal regions participated, as well as conservationists from nearby states, including representatives from New Jersey, Maine, Rhode Island, and New Hampshire. To name just some of the organizations presenting at the meeting-Mass Wildlife, Trustees of Reservations, Massachusetts Department of Conservation and Recreation (DCR), and US Fish and Wildlife. Gloucester was well represented. In addition to Deborah and myself, two members of the Animal Advisory Committee also attended; chairperson Alicia Pensarosa and former animal control officer Diane Corliss. Many of you may remember our Mass Wildlife Piping Plover intern Jasmine. She was there to give a presentation on habitat vegetation utilized by nesting Piping Plovers. Her aunt, Gloucester’s Terry Weber, was there to support Jasmine. This was Jasmine’s first time speaking in public and she did an excellent job!

Each region gave the 2018 population census report for nesting birds as well as providing information about problems and solutions. We all share similar challenges with predation from crows and gulls, uncontrolled dogs, enforcement, and habitat loss and it was very interesting to learn about how neighboring communities are managing problems and issues.

Just one highlight of a day filled with helpful insights and useful information is that we can be very proud of our state—Massachusetts is at the leading edge of the Piping Plover recovery effort. The representative from New Jersey was there specifically to learn from Massachusetts conservationists on how they could possibly improve their recovery program as the New Jersey PiPl population is not growing, with fewer and fewer each year retuning to nest. As you can see from the graph provided at the meeting, the Canadian recovery is going very poorly as well.

Readers will be interested to know that our region’s Crane Beach continues to have one of their best year’s ever. Trustees of Reservations Jeff Denoncour shared information on the latest census data from 2018 and Crane’s has a whopping 76 fledglings, with 25 more chicks still yet to fledge. Because of the huge success at Cranes Beach, the northeast region, of which we are a part, has fledged a total 136 of chicks in 2018, compared to 108 in 2017, and as I said, with more fledglings still to come! The northeast region encompasses Salisbury Beach to the Boston Harbor Islands.

Jeff noted that this year they had less predation by Great Horned Owls. Because of owl predation, several years ago Crane Beach gave up on the wire exclosures and now use electric fencing extensively. The Great Horned Owls learned that the Piping Plover adults were going in an out of the exclosures and began perching on the edge of the wire, picking off the adults as they were entering and exiting the exclosure.

Crane has an excellent crew of Trustees staff monitoring the Least Terns and Piping Plovers, as well as excellent enforcement by highly trained police officers. No dogs are allowed on Crane Beach during nesting season and dogs are prevented from entering at the guarded gate. As we saw from one of the graphics presented about nesting Double-crested Cormorants, when a dog runs through a nesting area, the adults leave the nest, temporarily leaving the eggs and chicks vulnerable to predation by crows, gulls, raptors, and owls.

Crane Beach Least Tern fledgling.

Compare the Least Tern to the Common Tern in the above photo. It’s easy to see why the birds are called Least Terns; they are North America’s smallest member of the tern and gull family (Crane Beach).

Another interesting bit of information shared–if you listen to our podcasts, back in April, we talked about the potential dilemma of what would happen if Snowy Owls remained on the beaches as the Piping Plovers returned from their winter grounds. Knowing that Snowy Owls (Bubo scandiacus) and Great Horned Owls (Bubo virginianus) are close cousins and that the Great Horned Owl eats Piping Plover chicks and adults, I was concerned that a Snowy might eat our PiPl. At one particular beach on Cape Cod, a Snowy stayed through mid-July. An adult Piping Plover skull was found in the owl’s pellet.

Snowy Owls remained in Massachusetts this year through July.

After attending the cooperators meeting, I am more hopeful than ever that our community can come together and solve the problems that are preventing our PiPl from successfully nesting and fledging chicks. What we have going in our favor is the sheer number of amazing super volunteers along with strong community-wide support.  

Piping Plover fully fledged and flying up and down the beach – we”ll have these next year, I am sure!

Two-Day-Old Least Tern Chicks

Clamoring for dinner, feed Me, feed Me!

In only one day’s time, you can see the teeny shorebirds gaining strength. As Dad approaches with dinner, the two-day-old Least Tern chicks stretch and flap their wings and open wide their beaks. The noisiest and flappiest is fed first. After depositing a minnow in one beak, off he flies to find dinner for the second sibling.

Camouflaged

The polka-dot fluff balls blend perfectly with the surrounding sand and rocks. The brilliant red inside the chicks mouth makes it easier for the adult terns to find them against the monochromatic pebbly beach habitat.

Waiting for dinner.

The tern parents will share feeding their chicks and fledglings non-stop for weeks; the chicks won’t be on their own for another two months.

For the first several days after hatching, Least Tern chicks keep fairly close to Mom in scooped out scrapes and natural divots in the sand, or well-hidden hidden behind rocks and beach vegetation.Tiny Least Tern Chick camouflaged in the sand, flanked by an adult Least Tern and Piping Plover male passing by (right).

Least Tern One Day Old Chicks!

The Rosetti’s Least Terns hatched both eggs and both chicks are doing beautifully!

Least Tern eggs are astonishingly well camouflaged on a pebbly beach, making them nearly impossible to see. It’s easy to understand why the species is threatened, and in some regions, endangered. Least Terns nest on sandy beaches with little vegetation, the same type of beach habitat that people love. Piping Plovers and Least Terns often nest in association with each other. In Massachusetts, the Least Tern is considered a Species of Special Concern.

Mom and Dad Least Terns take turns brooding the eggs. Here they are changing places. Least Terns are monogamous and the Rosetti’s Least Terns are especially good parents.

Least Terns are semi-precocial. Like Piping Plovers, which are fully precocial, Least Terns are mobile after one or two days and can leave the nest.

Unlike Piping Plovers, they cannot feed themselves and will be fed for the next eight weeks by Mom and Dad, a diet consisting mostly of tiny fish.

Tiny minnows, for tiny chicks. Dad does most of the feeding while Mom mostly broods the babies during the first few days. As the nestlings grow, the parents feed the chicks increasingly larger fish.

First day venturing away from the nest, and then returning to Mom for warmth and protection.

Just as the eggs are perfectly camouflaged, so too are the tiny nestlings.

Almost as adorable as are Piping Plover chicks are Least Tern chicks. However, they are much, much harder to film and to photograph. Least Terns are shyer of humankind than are Piping Plovers. Anyone who has seen PiPl in action know that they have a high tolerance for people and may come right up to you especially if you are standing perfectly still and are perfectly quiet. Least Terns on the other hand are elusive and skittish. The nestlings quickly take cover behind a rock or clump of beach vegetation when disturbed. The Mom and Dad when both courting and nesting will let you know if you are too close by dive bombing and if you still can’t take a hint, will poop on your head. If either happens, then you know for sure you are way too close and are interfering with the chicks feeding. Back away and observe from a more considerate (considerate-to-the-Terns distance that is).

Unfortunately, I recently observed a fellow photographer repeatedly being dive-bombed by a nesting pair of Terns, and that person has a humongously long telephoto lens. She would have gotten perfectly lovely photos from a distance more respectful of the Terns.
