The temperatures might not be what they should be for this time of year but don’t tell that to the salamanders and frogs that are beginning their migrations to their natal vernal pools to reproduce. I went out on a cold, dark, rainy evening to the town of East Brunswick to be a part of this magical experience.

Every year around mid to late March into early April, these little creatures get ready to begin their annual journey to their breeding pools. Usually the temperatures need to be above 40 degrees Fahrenheit, and on this night activity was a little slow going until the rains came. Vernal pools are an important part of salamander and frog reproduction as they provide the perfect hatchery to lay eggs in shallow water undisturbed by predatory fish. David Moskowitz leads the effort to safely monitor the amphibian migrations with Friends of East Brunswick Environmental Commission, a not-for-profit which provides many earth friendly programs throughout the year. The study area, Beekman Road, is a long winding country road surrounded by woods that runs between the amphibians’ upland habitat and their breeding grounds. The road is closed, thanks to the work of the East Brunswick Environmental Commission, on nights when the migration might occur, allowing the animals to cross the road safely and preventing roadkills. David explained that most of East Brunswick used to be covered by vernal pools, but since development has occurred, the land around Beekman Road is one of the last wildlife refuges in the area so it warrants protection.

All the conditions have to be right for these amphibian migrations, and it seems that tonight is going to a “big night” as families with flashlights in hand gather on Beekman Road by the bunches. David’s enthusiasm is contagious, as he runs around the woods like a little kid, turning over logs to look for spotted salamanders, explaining to onlookers about their biology, diet, and breeding. He leads us on a trail marked with pink flags to the vernal pool to listen to spring peepers calling in the night. At this vernal pool, you will also find Northern gray treefrogs, wood frogs, chorus frogs, and other frog, toad, and salamander species. As the rain begins to get heavier, I begin to notice more spotted

salamanders crossing the road and I save one from being crushed. This leads me to think about CWF’s Amphibian Crossing Project led by Mackenzie Hall, Private Lands Biologist, and I know she must be out in the Northwestern part of the state, doing exactly the same thing, helping these small, yet incredibly important animals, survive in our ever more developed world.

Update from Brazil #3: Kindness and Grim Deprivation

CWF’s Larry Niles and his colleagues are on a two-week trip to northern Brazil to trap and band Red Knots, Ruddy Turnstones, and other shorebirds on their wintering grounds. We’ll be posting summaries of his blog entries as he reports from the field.

Our team enjoys the ride to Curupu, unsuspecting of the wretched experience ahead. Our captain Joabe, seated at the back of the boat, not only helped us get on and off the island, but also helped us make the four-kilometer trip from the boat landing to the catch site.

After several days of trapping efforts on the mainland, we took the hour-long boat trip to Curupu, an island just off the coast of Panaquatira. Our trapping work here last year went off almost without a hitch, and we were off the island in less than 24 hours. So when we arrived this year, we naively expected this year’s expedition to go just as easily.

It didn’t. Instead, we suffered three days and two nights of oven-like tropical heat while being blasted by fine wind-driven sand and fighting the tides to catch birds. We slept with the tents sealed to protect us from the blowing sand, but this left us wet with sweat every morning. Mosquitoes met us in droves as we emerged from our tents before dawn light to set the cannon net. Sudden downpours chilled us to the bone, while the blazing sun that followed fried us.

A rainbow follows one of the many downpours that drenched us as we struggled to catch red knots on Curupu. A few rounds of soaking rain followed by blazing sun on our last day left the team in terrible spirits.

On the morning of our last day, the team endured several of these drenching rainstorms while resetting the net twice, following the retreating tide line. But our perseverance finally paid off. After three days of frustration, we were finally able to make a small catch. The eight red knots (compared to a catch of 115 last year) were fitted with new geolocators and set free to join the rest of the flock. After our short-lived deprivations, we hoped to be free of Curupu.

Not quite. We had hoped that we could leave by midday, but transporting our equipment to the boat landing was delayed by yet another downpour. When we finally made it to the landing, we found that we couldn’t leave until an incoming tide. We were facing the possibility of another night on the island.

A happy team gets to work processing the final day’s catch, which included four ruddy turnstones with geolocators. Combined with our previous catch of nine, we have deployed all 30 geolocators and recovered six thus far. Geolocators collect data for 1 to 2 years and can store it for far longer.

Expecting only tribulation, we were suddenly met with kindness. Indio Sousa, the father of a Brazilian student who joined us for our misadventure, and who manages a compound of houses on the island, invited us to stay in the guest quarters. While we luxuriated in what felt like our first shower in months, he served us platters of watermelon and pineapple and cooked a plate of shrimp, then fish. As we enjoyed his generosity, we relaxed in the languid late afternoon tropical heat, cooled by gentle breezes, while being serenaded by the melodious song of native forest birds and amphibians.

The overnight provided us with more than cool air. It also provided a last chance to trap, this time for willets. We had brought 30 geolocators to attach to these poorly understood temperate breeders, one of only three shorebirds that breed in New Jersey, and an emblematic species of the breeders of Delaware Bay.

Unfortunately, it was not to be. The operation needed precise timing, an unlikely event in our short-lived experience in northern Brazil, especially given our bad fortune. The captain of the small boat that brought us to this island came late, then ran out of gas while taking us to the catch site. Finally arriving at the roost that we scouted at the start of the trip, we faced an already declining tide. We tried to catch, but the island defeated us one final time.

But back on the mainland, we were once again blessed with kindness. As we fled to our home base, the parents of another Brazilian student on our team graciously offered a home-cooked meal, a very generous offer considering the size of our group and their own modest means. We left their home with full stomachs, warmed hearts, and mixed feelings about the wild coast of Brazil.

Update from Brazil #2: Down to Work

CWF’s Larry Niles and his colleagues are on a two-week trip to northern Brazil to trap and band Red Knots, Ruddy Turnstones, and other shorebirds on their wintering grounds. We’ll be posting summaries of his blog entries as he reports from the field.

Cannon netting in a remote place increases the odds of failure, and cannon netting in Brazil may be the most difficult of all. For one thing, cannon netting requires an enormous amount of equipment not easily available in places like northern Brazil. Take covering material, the opaque cloth that is widely available in the US to shade hothouses. We use it to shade the birds caught under a net to protect them from the sun and to calm them. After visiting many stores, we found something similar in São Luís, not equal to the need, but sufficiently suitable to be useful.

Mark Peck and Joe Slusher are loading cannons with igniters made from Christmas tree lights. They work, but have a more uncertain reliability.
Mark Peck and Joe Slusher are loading cannons with igniters made from Christmas tree lights. They work, but have a more uncertain reliability.

But for the igniters we use to fire the cannons, it’s a much different story. Even in the United States, the authorities tightly control their use for obvious reasons. Igniters are what miners use to blow up rock, and thus potentially dangerous in the wrong hands. As far as we know, they cannot be found in Brazil, and we can’t even receive them if we sent them from the US. Only a government official can do that, and our colleagues in Brazil were unable to get permission to do it.

We overcame this nearly insurmountable difficulty by going to the Internet. We soon learned how to create an igniter with small Christmas tree lights. Cut the glass top off of the light and charge with a minor electric current, and they pop like the real thing.

Worse yet is gunpowder. We use it to fire the projectiles that carry the net over the birds. Without it, we have no expedition. But in the South American countries in which we have worked, the authorities tightly control gunpowder. Here in Brazil you need a license, and forget about getting one if you are from the United States.

We found gunpowder in this religious goods store in the center of São Luís. The other side of the store was filled with (to my mind creepy) goods from African or Caribbean origins. Being Catholic, I have to admit that I was reluctant to photograph this store for superstitious reasons. Being Methodist and British, Humphrey Sitters had no qualms whatsoever.

But we persisted, and after a bit of investigation, we learned that Brazilians use black powder in religious ceremonies. We would eventually find powder in, of all places, a religious goods store with a mix of religious iconography impossible to find in the US. Think Blessed Virgin Mary meets voodoo goat head devil god. As if blessed by the Holy Mother, we found all the powder we needed just beneath her benevolent and loving image.

In other words, to be successful in a cannon netting expedition, one must be resourceful. Ultimately it depends on two things: the team and the people in country that help you. This year in Brazil we are fortunate on both counts. Our Brazilian colleague, Ana Paula Sousa, is from the Universidad Federal de Maranhão and lives in São José de Ribamar, only five miles from our field station. We work under her banding permit and with her professor, Dr. Augusto Rodrigues. It was her that provided us with the field station we call home.

Ana’s generous nature comes naturally. Her father and mother Omar and Diva Sousa have been vital to overcoming the minor obstacles that seem to arise everyday when running an expedition in a rural area, from fixing the cranky generator and well pump to finding hard to find supplies like net-mending line and block ice. All this, and yet Mr. and Mrs. Sousa refuse our offers of compensation for their time. They do it because of their pride for their daughter’s chosen vocation, the native spirit of generosity, and their own big hearts.

Update from Brazil: News from Our Shorebird Scientists

CWF’s Larry Niles and his colleagues are on a two-week trip to northern Brazil to trap and band Red Knots, Ruddy Turnstones, and other shorebirds on their wintering grounds. We’ll be following him and posting summaries of his blog entries as he reports from the field.

 

When most people think of Brazil, they think of Rio de Janeiro, a modern city that will soon host both the World Cup and the Summer Olympics. Or they may think of the Amazon jungle, and all the wonders of a wilderness alive with fascinating wildlife and plants that can found in no other place.

The town of Panaquatira perches precariously along the Atlantic shoreline of northern Brazil, about 250 miles east of the mouth of the Amazon.

Except for an eight-hour layover in Rio, we are not going to these places. Instead, our home for the next two weeks will be Panaquatira, a tiny town on the northern coast about 250 miles east of the mouth of the Amazon. You could not imagine a more coastal town – the main street is the beach. Residents ride the mile-long strand to get to their modest homes in all but lunar tides, when the sea laps onto the stone driveways. The town is a resort for the working class, who mostly stay for the day, often arriving by bus to enjoy a frolic on the wave-washed sandy beach.

Heavy projectiles powered by gunpowder pull the net over birds quickly. The speed of the cannon net is key to catching fast-moving shorebirds.

But we have not come to recreate. Our team of nine hearty souls will attempt to capture shorebirds that breed in the Arctic and winter here in the Maranhão state of Brazil. This forlorn and remote shoreline supports one of the most important concentrations of shorebirds in the hemisphere. Each year, thousands of red knots, ruddy turnstones, black-bellied plovers, whimbrels, and other species spend the winter here in a hot and humid climate that is the exact opposite of Arctic weather. Why do they winter here? What attracts them to this place? Where the Arctic do they breed? What other places are vital to their enigmatic lives? These are some of the questions we hope to answer.

The output of a recovered geolocator, this map shows the yearlong track of a red knot with the flag Y7H. We attached its geolocator on Delaware Bay in 2011 and recaptured it in 2012. The track shows it left Delaware Bay, passing through Hudson Bay on its way to its Arctic nesting area. In July, it flew south though James Bay, stopping on the US Atlantic Coast before making an epic flight that took it over 1,000 miles out into the ocean to avoid a storm. After four days of flying, Y7H finally reached the coast close to our study site.

Last year we trapped the beaches of Panaquatira and nearby island of Curupu. We caught red knots and ruddy turnstones with cannon nets and banded them with tiny devices called geolocators that track movement and store daily locations on a tiny memory chip. Geolocators are a digital treasure chest, but they can only be unlocked if we recapture the same birds and retrieve the devices.

Working in this remote place at the center of the world creates a challenge. What we call necessities are luxuries here, only available to a lucky elite. Everyone else struggles to achieve modest livelihoods at best. It’s a place where basic sanitation and clean water are still a modern improvement not yet available to the majority of the population; a place where warm-hearted and generous people must face persistent lawlessness, both in the street and in the halls of power. I fear the water, the parasites, and the thievery that the residents suffer with equanimity.

These colorful fishing boats, typical of the region, are powered by one-cylinder engines similar to those that served as workhorses of small boats 50 years ago in the United States. Some rely on sail power alone.

Don’t get me wrong. I live in New Jersey, less than an hour from Camden – one of the poorest places in the country and one of the “murder capitals” of the US. Still, we are threading a needle here. We don’t come as tourists, or on business per se. Panaquatira will be our home, and we must pull together a complicated effort that can only be successful with help and generosity of the residents. In return we hope to shed light on the circumstances of the birds and people of this wild and isolated place.

Road Salt – Friend or Foe?

New Jersey has been immersed in one of the coldest and snowiest winters in recent history.  With all that ice and snow, comes the task of clearing and keeping our roads passable so we can go about our daily lives.  Road salt is our go-to substance but it wrecks havoc on the environment, corroding metal, killing vegetation, and polluting our watersheds.

This article written by Lloyd Alter from Treehugger.com sheds some light on the problem and perhaps some alternatives.

 

Searching for Snowy Owls

By Charlene Smith, Program Coordinator

On a cold blustery January morning I decided to brave the elements in the hopes of catching a glimpse of the Snowy Owl irruption occurring in our area.  Since as early as December, the owls have been showing up all along the east coast hanging out by our beaches as it is similar to the barren habitat that they are accustomed to in the Canadian Arctic. The reason why we are seeing so many snowy owls this year is because of good productivity on their breeding grounds.  There was a huge supply of lemmings this past summer that created an abundance of young. Most likely the owls that we have been seeing are juveniles who don’t have their own territories and have moved south possibly looking for food.

On my 45 minute ride out to Sandy Hook, I keep thinking that I was crazy to be doing this. What are the chances that I could spot this rare owl on a 7 mile stretch of Barrier Island?  The odds were against me but I had a hunch on where to look.  I arrived at Sandy Hook, grabbed my newly purchased Nikon binoculars and my Canon camera and took off in the hopes of finding an owl and catching a few shots.

As I walked along the paved path that runs along the water, I scanned the tops of the buildings for a large white bird.  I noticed a few people gazing up and pointing to something in the distance. I hit the jackpot!  I quickly came upon the group and locked my binoculars to the top of a chimney in absolute amazement and disbelief. There sat perched a beautiful snowy owl with faded barring, its eyes half closed, half open. With every noise it would rotate its head around in the direction of the intruding sound. We patiently waited for the owl to take off in flight and when it decided to move, we gasped in awe. It flew over to some pilings by the water and waddled cautiously up the wooden beams, occasionally starring back at the crowd of onlookers.  It was clearly annoyed by the group watching its every move and in an instant it decided to fly off while the people with their telephoto lens and binoculars followed suit. I was chilled to the bone and couldn’t feel my fingers anymore. As much as I wanted to follow the owl I decided it best to appreciate the wildlife from afar and respect its boundaries. I was grateful for the experience and that I could proudly tout that I saw a snowy owl in New Jersey of all places. This is a once in a lifetime occurrence and I recommend taking the time to find a snow owl, but onlookers beware – Keep your distance and respect the owls boundaries.

The Cornell Lab of Ornithology is keeping track of snowy owl sightings with their eBird project, a real-time online bird checklist program.  Another interesting site is Project SNOWstorm, a site dedicated to collecting important data regarding this season’s snowy owl irruption. Scientists are affixing solar-powered GPS transmitters to snowy owls, which records the owls’ location every 30 minutes via cell phone towers.  Almost nothing is known about the local and landscape-level movements of snowy owls on their wintering grounds, nor about their nocturnal hunting activity and range size so information from these transmitters will help to discover more about their habits and habitats.

BAHAMAS PIPING PLOVER PROJECT

WINTERING PIPING PLOVER SURVEYS ON ABACO

By Todd Pover, Beach Nesting Bird Project Manager and Stephanie Egger, Wildlife Biologist

An integral part of this Bahamas trip entailed surveying several sites not previous covered on Abaco and revisiting some sites not checked since the 2011 International Piping Plover Census. Although we didn’t find large concentrations of piping plovers at any one new site, we did make some noteworthy discoveries.

One of the most exciting find was the resight of a piping plover that was banded on the breeding grounds last summer in Massachusetts as part of a flight behavior study. New Jersey also participated in this research and we briefly thought it might be one of the birds banded in our home state – but it turned out that it was banded (and nested) on Chapin Beach, Cape Cod and is wintering at Schooner Bay, Abaco (amongst 15 other piping plovers found on our survey).

Volunteer Guest Bloggers – Bahamas Piping Plover Project!

Connecting with Piping Plovers in a New Setting

This trip to the Bahamas we had three volunteers, piping plover experts, to help us survey stretches of Abaco that we have either not been able to survey or had limited opportunity to survey in the past. Our volunteers have a wide range of experience ranging from the U.S Fish and Wildlife Service, Pronatura Noreste A.C. Mexico, and a wildlife consulting company in Virginia. Below is their experiences from the week. Enjoy!

When I retired a year ago after spending the better part of my career negotiating with stakeholders and regulatory agencies to balance piping plover protection with shoreline stabilization projects and human recreational use, I often joked that I was going to move somewhere with no plovers- no piping plovers, no snowy plovers, and not even mountain plovers.  But when CWFNJ invited me along to survey for piping plovers in Abaco, Bahamas I jumped at the chance to learn more about piping plovers on their wintering grounds. My work with plovers in the northeast U.S. had focused on plovers on their breeding grounds where individual pairs of plovers fiercely defend their nesting territory. As a result, its unusual to see more than a pair of plovers and their brood of up to 4 chicks in a single spot. Here on the wintering grounds the bird’s habitat characteristics are very similar to that of their breeding areas – wide sandy coastal beaches, but their behavior is very different. The plovers congregate in small groups, roosting and feeding together. On my first survey day, I was thrilled to observe a group of eleven plovers roosting high on the beach. It was strange to see so many plovers calmly sitting together. Each bird was nestled down in a small depression that gave protection from the wind, reminding me of the shallow scrapes they make when building nests. It was great to finally see where the birds go when they leave the northeast and personally rewarding for me to now have observed the birds throughout their entire annual cycle.
