Technology has proven to be vital to Conserve Wildlife Foundation’s work protecting rare wildlife species over the years. Our biologists depend greatly on modern technologies to band, track, and share online the journeys of wildlife. Our webcams broadcast the most intimate behaviors of nesting birds and bats across the web. And we seek out ever-evolving communications technologies to spread the word about the inspiring stories of wildlife, from social media and infographs to e-books and Story Maps. These technologies offer newfound abilities to share complex data on multiple levels, while still incorporating the awe-inspiring photography and videos that bring wildlife’s stories to life.
Conserve Wildlife Foundation of New Jersey is excited to offer our 2015 Annual Report in a unique format that utilizes one of those technologies – Story Maps. In the past year, we have explored the lives of seals, eagles, and freshwater mussels with Story Maps – and the annual report allows all of our projects to be highlighted in this interactive format as well.
Visit the multiple pages within this Story Map to learn about Conserve Wildlife Foundation’s many projects and partnerships in 2015, and the imperiled wildlife species in need of our help. Find examples of the innovative and dedicated leadership of our biologists and volunteers. And take an online journey across the state to learn how our projects made a difference in all corners of New Jersey in 2015 – a great year for wildlife in the Garden State!
Horseshoe crabs may be one of the most unusual animals in the world, but they’re also one of the most extraordinary. They’ve been around for hundreds of millions of years, and we’re only now starting to understand just how important they are – not just to the natural world, but also to the world of medicine. Discover the real value of horseshoe crabs, found throughout New Jersey’s Hidden Coast – the Delaware Bayshore.
A new episode of our video series “New Jersey’s Hidden Coast” will air every two weeks throughout the summer! Catch a glimpse of the bay, the horseshoe crab at the center of the bay’s system, and the incredible relationship between horseshoe crabs and migratory birds, like the red knot. We will reveal the real value of horseshoe crabs, the challenges to the ecosystem, and the potential for a thriving regional economy along the Bayshore. We will show Hurricane Sandy as a catalyst for decisive action and the work being done to rebuild the area for both people and wildlife.
Over the next several weeks, we will explore the use of “living shorelines” instead of bulkheads and the central importance of marshes to the marine ecosystem. We will discover the on-the-ground, grassroots efforts of the community to build oyster reefs alongside veterans. And we will examine the future of the Bay and the work that needs to be done to preserve our conservation successes thus far.
2016 Species on the Edge Art & Essay Contest Winners honored at Awards Ceremony

2016 Species on the Edge Winners with representatives from CWF, Wakefern, PSEG and GAF.
On Tuesday, May 24, 2016, Conserve Wildlife Foundation of New Jersey celebrated and recognized the winners of the 2016 Species on the Edge Art & Essay Contest, a statewide educational contest open to all fifth-graders. The 14th annual contest encourages students to become wildlife biologists through their research and artwork on the endangered and threatened wildlife species in New Jersey.
“These talented children poured their hearts into the Species on the Edge contest, creating vibrant artwork and passionate essays about these rare wildlife species,” said David Wheeler, Conserve Wildlife Foundation Executive Director. “We are inspired to help connect the next generation of New Jersey conservation leaders with the natural world around them. Their art and essays illustrate the wonders of nature – and reveal many of the challenges we must overcome to help vulnerable wildlife survive in our densely populated state.”
Students were asked to draw a picture of one of New Jersey’s over 80 endangered and threatened wildlife species and compose an essay about how the animal became endangered and what can be done to help protect it. The Species on the Edge Art & Essay Contest encourages students to learn about local environmental issues, express their concerns for the world around them, think creatively about ways to improve it, and to consider how their actions impact the natural world.
This year’s ingenious group of winners was honored at an awards ceremony which was hosted at the New Jersey Education Association, in Trenton, New Jersey. The contest was sponsored by PSEG, NJEA, GAF, Atlantic City Electric, Church & Dwight and ShopRite.
The statewide contest drew over 2,000 entries from across the state. Since 2003, over 10,000 children from across New Jersey have entered the Species on the Edge Art & Essay Contest.
Encouraging a Conservation Ethic in Locals and Travelers Alike
by Kelly Triece, Wildlife Biologist
Even though Honduras is no larger than the state of Tennessee, the country is very diverse in landscape and wildlife. In a short period of time, you can travel from the Caribbean and lounge on its white sand beaches and then visit the high-altitude pine forests. You can also see the Honduran emerald, an endemic hummingbird in the arid dessert. The diversity in eco-types and warm climate makes Honduras a great candidate for ecotourism, a growing industry since the 1990’s.
While Honduras is very diverse in climate and landscape, for many years it has been a country based on agriculture. Cattle ranching and growing cash crops, such as coffee and bananas, are common. While subsistence farming is essential to the Honduran way of life, the wide-spread slash and burn method to create agricultural land is destroying many Honduran forests and other landscapes. Since the country is rich in forest, marine and other natural resources, ecotourism can have many benefits on the land and the economy. Ecotourism may have the potential to serve as another way of living for Hondurans.

During my stay in Honduras, I had the opportunity to meet many local conservationists eager to make a living off environmental education and ecotourism. We met with one such man, named Isidro on the fourth day of our trip. Upon arrival, we were offered some fresh brewed coffee from his farm and then headed straight through the forest for a tour of his land. Isidro bought the land in the 1990’s and has since been managing the land for bird habitat. Isidro told us he originally bought the land to raise cattle, but eventually decided instead turn the land into a nature preserve for wildlife.
He now resides with his wife and children on the property and dreams to have an environmental education program, where people come to hike, eat fresh local tilapia and view wildlife. At the environmental center, adults and children will have the opportunity to go bird watching, take a hike and learn about the importance of the natural world. He grows citrus, avocados and other fresh fruits, leaving many fruits just for the birds as well as shade grown coffee. This form of ecotourism is a way to bring nature and people together. Once children and others care about the natural world around them, they too will work to preserve it. It also provides a sustainable way of living for those like Isidro and his family.

Education about the environment through hands-on experience, as well as formal education, has the potential have a significant impact on local communities. While visiting the Universidad de las Agricultureal (Agriculture University) in Olancho we had the opportunity to take place in the Feria de Aves Migratorias (Migratory Bird Festival). The festival was put on by the Juniata Valley Audubon Society and Ruth Bennett, Ph.D. student at Cornell. The festival was part of a program that educates Honduran families that live very close to national parks. The program teaches children about the national park, local flora and fauna and its overall ecological importance.

We had the pleasure of attending the festival, where we colored pictures of birds with elementary children and spoke to the college students. Most of college students are majoring in Natural Resources and are eager to learn about becoming a biologist. Students also compete in bird photography contests, present posters and learn about the natural history of migratory songbirds. The festival brings education and awareness to migratory songbirds, especially the Golden-winged Warbler.

Through education of Hondurans and visitors alike, ecotourism has the potential to serve both the local communities and those visiting the country. Ecotourism should inform tourists about the environment and wildlife they are seeing, as well as help local populations understand the importance and value of their home. Through the combination of education and ecotourism, a sense of stewardship can be fostered by encouraging travelers and locals to be mindful of their natural resources and instill a sense of wonder about the natural world. For those who are educated about wildlife and the natural world, will often work toward preserving it as well.

In Honduras, wildlife is all around. Melodious blackbirds, Social flycatchers and Violet-crowned wood nymphs, fly tree to tree in and among the villages and farm fields. When children, such as those at the migratory bird festival, learn the importance of biodiversity, they too will want to protect these amazing animals. Ecotourism not only provides a way to travelers to see exotic wildlife, it also provides a way of living for locals. It is through sustainable ecotourism and education that Honduras can continue to be rich in culture and wildlife.

One of a Series of Updates on the 20th Year of the Delaware Bay Shorebird Project
by Dr. Larry Niles, LJ Niles Associates LLC
In spite of the very spotty horseshoe crab spawn, the shorebirds on Delaware Bay seem to be gaining weight on schedule. Below you will find a graph composed of the average weights of all the red knots by our team for the last 20 years. The curve is the result of combining all the data we collected and shows the sweet spot for most knots. As they arrive, they take time to gain weight but after about 5 days they start gaining weight rapidly. After the 26th or so, birds start reaching the critical weights necessary to safely reach the Arctic breeding grounds. One can see the curve deep at the end of the month because fat birds fly off leaving the less fat behind. In general, weights above the line are good, below the line not good. The large squares on the graph are the average weight of this year. So far, so good.

This is a bit of a surprise for the team. The weather here on Delaware Bay is wet and cold. The water temperature struggles to lift above 59 degrees, the temperature necessary for a crab to spawn on Delaware Bay. So far, the temperature has been below 59 degrees more than above. We had good spawns in the last few days, but only in key places.
Water temperature at the mouth of Delaware Bay.
A key place for horseshoe crab spawn happens to be the mouths of small creeks. The New Jersey side of Delaware Bay is blessed with many small intertidal creeks, most draining only marsh or small inland watersheds. Some of these creeks have names, Goshen Creek, West Creek, Nantuxent Creek, but many do not. Almost all have shoals at their mouth with the bay because bay currents, tidal flow and wind driven waves act against each other to settle sand coming from adjacent beaches or from inside the creek drainage. Much of the sand lost from our restored beaches settles into these shoals. For horseshoe crabs, these shoals are sweet places.

At the time of this picture, over 3,000 knots and 1,000 ruddy turnstones were using the shoal and the inner sandy beach behind the shoal. Photo by Stephanie Feigin.Red Knots in flight on Cooks Shoal.

Usually, the shoals lie just under the high tide line and are composed of large grain sand, the optimal conditions for a good crab spawn. However, the most important characteristic and key to this unusually cold May, is the warming water flowing out from the marsh drainages. On a flooding tide, colder warmer flows into the vast marshes of the Delaware Bay. This warms the water. On an ebbing tide, it flows out the creek and over the shoals, making them slightly warmer and more conducive to inducing crabs to spawn. Even on these cold days, they literally climb over themselves to breed on the shoals. The shoals also protect the inner mouths of the creeks thus making the sandy shores at the mouth of the creek a crab spawning heaven.

However, as it seems usual with this blog, there is a growing concern. Right now, most of the red knot population on the bay is feeding on these shoals along with thousands of other species, but only half have arrived from southern wintering areas. We now have about 12,000 red knots on the bay and in a day or two we should find another 12,000 falling from the sky. Will there be enough eggs? Will the water temperature finally reach normal levels? These are the important question for the next few days.
New, weekly updates from New Jersey’s beach nesting bird project team
by Todd Pover, Beach Nesting Bird Project Manager
American oystercatcher Chick
It has been a busy week on the beach nesting bird project! We had our first least tern nests of the season, as the brief spell of warmer weather (finally) made for a burst of breeding activity. The first American oystercatcher nests hatched, so we have chicks on the beach now, as well.
Least Tern Nest
And there was a big spike in new piping plover nests all along the coast, so we were busy erecting “predator exclosures” to protect the eggs from predators, such as crows, cats, gulls, and foxes. While they are not effective or viable to use on every nest, these wire cage structures are one of our best management techniques to increase hatch success by deterring predators.
Piping Plover Exclosure
This week we will be even busier, as we make a mad scramble to protect the nests and colonies before the crowds of beachgoers arrive for the Memorial Day weekend!
One of a Series of Updates on the 20th Year of the Delaware Bay Shorebird Project
By: Dr. Larry Niles, LJ Niles Associates LLC
Shorebirds and no horseshoe crabs along the Bay.
It’s well known that the Delaware Bay shorebird stopover depends on horseshoe crabs, but few know that Delaware Bay is a near perfect horseshoe crab habitat.
There are many places on the eastern seaboard where horseshoe crabs breed. Most are too small to provide sustenance for energy-starved shorebirds. Places like Cape Romain Refuge in South Carolina have enough horseshoe crabs so that one breeding female unearths eggs of another and thus lays out a tidy meal for shorebirds. But the areas are small and at this time unimportant to the population of shorebirds. Most of the others are too small to have eggs reach the surface. Its only in Delaware Bay where crab numbers reach into the millions and spawn in such great numbers that they spread like a carpet over nearly all beaches from Gandy’s Beach to Villas, approximately 20 miles of spawning habitat. The number of eggs and ultimately hatched young reach staggering numbers.
Horseshoe crabs breeding at night.
The huge population of horseshoe crabs on the bay is no accident. The bay almost seems built to suit the crabs. Crabs need beaches with large and deep sand flats, allowing just enough water to sufficiently oxygenate the eggs without drowning them. They need the sea floor to gently rise into breeding beaches, allowing easy access. While breeding, crabs have to eat small bivalves, which they find in abundance in the bay’s extensive intertidal and subtidal flats.
Horseshoe crab eggs.
The most important aspect of the bay is its quickly warming waters in the spring. On Delaware Bay, horseshoe crabs don’t breed until waters reach 59 degrees. You won’t see this temperature on the Atlantic Coast until June. Not so on Delaware Bay! Although the bay has deeper water, mostly in sloughs that snake under the surface out to its mouth at Cape May, most of the water is relatively shallow — usually less than 18 feet. That may sound deep, but keep in mind the Chesapeake has 100 feet water for most of its length and deeper water throughout. The shallow water of Delaware Bay allows it to heat up soon after the air temperature rises.
Unfortunately, it also cools down quickly and because of this the crab spawn has stopped. The bay’s water temperature went up dramatically in late March and April, so much so that we worried it might reach the critical 59 degree threshold in April long before the birds arrived in May. But then the warm weather stopped and the bay temperature dipped than rose, several times in fact. By early May, it had gotten just above the threshold, heating up to about 61 degrees at the Cape Henlopen marine buoy. We hoped for the best. Crabs started to breed in good numbers on a few beaches, like Reeds Beach, but were thin elsewhere. We had about 20,000 shorebird relying on the spawn and the eggs that were brought to the surface.
Than the bay cooled down again. A nasty western wind and cold front enveloped our area over the weekend and the cool weather followed. By Monday, the temperature went down again and the crab spawn stopped. This is bad.
When the spawn stopped the birds hovered up the remaining eggs in a few days. Then they started wandering to find eggs in odd places, under houses, along bulkheads. Some even went to areas like the oyster aquaculture racks to find eggs to the delight of the people trying to expand aquaculture. But what they saw was desperation.

Worse the Black Back and Herring Gull that feed on eggs and overturned crabs couldn’t find eggs and started eating shorebirds. By the end of Thursday (May 19) we found 8 dead red knots. These gulls can swallow small sanderling and semipalmated sandpipers like gum drops, so we really don’t know how many shorebirds died.

Relief might be in sight though. Thursday, Friday and today will be warmer. The bay’s temperature is back up over 60 degrees. Thursday night we had a fairly good spawn. Hopefully we will be back in business soon.

A Series of Updates on Year 20 of the Delaware Bay Shorebird Project
By: Dr. Larry Niles, LJ Niles Associates LLC
Our team trapped over 500 shorebirds over the weekend including several hundred red knots in two catches on May 12th and 14th! Most of the caught birds, knots, ruddy turnstones and sanderlings arrived in good condition, which is always a relief at this early stage in the season. Ruddy turnstones returned in better-than-average condition, weighing in at 5 grams higher than normal arrival weights.
Team banding ruddy turnstones on Reeds Beach.
The condition on arrival is an important focus of the project. In some years, knots struggled to get to the bay, coming in at average weights of 105 grams, 15 grams lighter than this year. One poor soul practically fell onto the beach with only 84 grams of weight, dangerously burning muscle to get here.
To really understand it best you must put yourself in the birds’ shoes (in a matter of speaking). We can do this because we have been attaching small tracking devices called geolocators on knots and turnstones for the last 5 years. Geolocators must be recovered to download the data, and we did this with a knot banded with the inscribed flag TVV in 2015. The map of that bird’s heroic journey can be seen below.
Delaware Bay, New Jersey, USA
Follow TVV’S path from Delaware Bay to its Arctic breeding area, then down to its Chilean wintering area, then back to Delaware Bay. It spent less than one month in the Arctic but over 6 months in its Tierra Del Fuego winter quarters. The rest of the time was spent flying or resting between flights. It’s flight from Southern Brazil to Delaware Bay was truly awe inspiring!
Imagine you are TVV and about to fly from balmy Brazil to Delaware Bay, 5,000 miles away. Most birds will leave near nightfall, when the weather is settled and usually when there tends to be a favorable wind. Once aloft you have no idea of the conditions you will face for the next 6 days. Some birds have an easy time of it, some get caught in opposing winds, others get blown off course and must struggle to return. This is the reason for the varying weights on arrival.

So what did the birds find when they arrived this year? So far, the horseshoe crab spawn has gone well. It started early in the month, so that by the time birds like TVV arrived, they found a nice concentration of eggs for the taking on Delaware Bay beaches. At first, the birds poured into the bay. Last Thursday May 10th, we had about 1,000 knots on the New Jersey side of the bay. By Saturday, the number has grown to 8,000 knots – and our two catches proved they were gaining weight at a good clip.
All that changed on Sunday when a complicated cold front hit the bayshore. For two days we have had strong winds from the west, creating breaking waves on much of the New Jersey bayshore. The crab stopped spawning in most places. The winds blow as I write this blog and is certainly holding up birds from arriving, some may have stopped migrating others are fighting this merciless 30 mph wind.
