Join us on this fascinating journey into the world of the Diamondback Terrapin

Last week, I drove slowly down a road with no buildings or homes on either side, with only vast salt marsh as far as the eye could see. Over the course of the roughly 10-mile round trip, I passed maybe four other cars. But there was another kind of traveler that I found in abundance – 22 diamondback terrapins crossing the road on the way out, and another 18 of these gorgeous turtles on the way back (although I’m sure I saw some of them twice)!

Amazingly enough, this was a drive along the New Jersey coast in June. If you haven’t guessed it, I was on Great Bay Boulevard in Little Egg Harbor. And if you haven’t been there, now is the time to go – it is a true wildlife spectacle that you have to see to believe.

New Jersey’s coast is filled with wonders during the summer months – wonders that go beyond its crowded beaches, boardwalks, and traffic jams! Believe it or not, the coast still has plenty of nature to be found, often in total seclusion. And diamondback terrapins offer as amazing a wildlife story as any.

So today we kick off Terrapin Week! Read our first installment below for an up-close look at the terrapin’s habitat, appearance, range and status. Then stay tuned for a brand new story each day this week by our terrapin biologists Ben Wurst and Stephanie Egger, with topics including our biologists’ research projects, how our volunteers are making a difference, terrapins across the East Coast, and New Jersey locations where you have the best chance of seeing terrapins in the wild!

Meet the Terrapin

by Stephanie Feigin, CWF Program Coordinator

Northern diamondback terrapins (Malaclemys terrapin terrapin) are native to New Jersey and inhabit the many miles of coastal salt marshes and estuaries along the Atlantic Coast and Delaware Bay. They exclusively inhabit coastal salt marshes, estuaries, tidal creeks and ditches with brackish water (a mix of both salt and freshwater) which is bordered by spartina grass. They are the only turtle species in the world that is specially adapted to spend its entire life in this type of water. 

The northern diamondback terrapin is a medium-sized turtle that varies in length from only 4 to 5.5” in males to 6 to 9” in females. Terrapins have a gray, brown, or black carapace (top of shell) and a lighter plastron (bottom of shell), which is a greenish-yellow. The skin is light to dark gray with black spots and other dark markings. Both sexes have a light colored upper mandible. They are named for their diamond shaped pattern on their carapace. Adult terrapins primarily eat mollusks and crustaceans, including snails, fiddler crabs, and mussels. They also eat blue crabs, green crabs, marine worms, fish, and carrion.

Terrapins are cold-blooded, or ectothermic. They hibernate during the winter and bury themselves at the bottom of or in the banks of creeks and ditches. Studies have shown that terrapins also exhibit a high level of site fidelity or they return to the same territory every year, some even occupy the same small creeks year after year. Terrapins have a very small home range, from Cape Cod, Massachusetts to Cape Hatteras, North Carolina.

In 2001, a status review of reptiles in New Jersey recommended that the Northern diamondback terrapin be listed as a species of special concern in New Jersey. The listing as special concern “warrants special attention because of some evidence of decline” (NJ ENSP-Species Status Listing) and little is known about their actual population status in New Jersey. However, terrapins are still harvested for food in New Jersey and the total harvested annually is not known. Since Terrapins are still considered a “Game” species subject to harvest, the Special Concern designation was never officially applied to the species and will not be until they are re-classified as a “Non-game” species.

Major threats to the health of the population include; habitat loss, mortality from being drowned in crab traps, and road mortality. Each year hundreds of terrapins are killed by motor vehicles throughout their range and here in New Jersey. The Conserve Wildlife Foundation (CWF) and their biologists are working hard to protect these incredible reptiles with their many conservation efforts. We are asking you to “Be Terrapin Aware” while driving along roads in New Jersey’s coastal region, and stay tuned for more posts during Terrapin Week about our efforts to protect these turtles!

Young osprey develop so fast!

Slow down, don’t tailgate and help a terrapin cross safely!

by Ben Wurst, Habitat Program Manager

This week the annual nesting season of northern diamondback terrapins began. Females leave protection of our coastal estuaries to seek out suitable nest sites, course gravel and sand, which is often along roadsides. These individuals often cross roads to get to these nest sites. Please be courteous of terrapins and slow down, leave a greater following distance, and help a terrapin cross when you see one on the road.

• You can report sightings of terrapins on roads on our website
• Share photos of terrapins with our Flickr group

 

A productive nest on the Navesink River needs a helping hand!

by Ben Wurst, Habitat Program Manager

UPDATE: We have learned that the pole has been straightened!! Thank you all for the support!!!

Many North American ospreys have already departed from their wintering grounds in Central America, N. South America, and the Caribbean and are on migration to their summer breeding grounds. In New Jersey, most ospreys nest along the Atlantic Coast, from Sandy Hook to Cape May and arrive in mid-late March. One nest (083-A-007) is on a decommissioned channel marker (#21) on the Navesink River, off Fair Haven. The nest was first found in 2006 and in 2013 the nesting pair successfully produced three young. Considering the current condition of the nest pole, they were really lucky to produce any young at all!

This platform was one of many that sustained damage by Superstorm Sandy. We pledged to repair any and all platforms that were reported as damaged by the Storm and did; however, we don’t have the equipment or boats to repair a leaning platform in open water, like 083-A-007. Since it was damaged we have been contacted by many concerned citizens who watch the pair that nests here. We’re sharing this story to help garner support to repair the nest pole.

Ospreys mate for life and return to the same nest site, year after year.  They will build their nest at an angle to compensate for the lean, but young are still in jeopardy of falling out of it. Our goal is to get it fixed before the pole falls over. Lastly, this is an important nest site in the region. There is very little preserved open space in this region of Monmouth County and very few osprey nests.

We need your help!

Last year we tried reaching out to local marine construction and bulkheading companies but had no luck getting anyone to even return our calls. Then we contacted the Bureau of Coastal Engineering’s Aids to Navigation and they did not have equipment in the area to make the needed repairs last fall (we’ve since called them again to get their assistance and are waiting to hear back).

Do you know any local bulkheading or marine construction companies who work in the Fair Haven/Rumson area? If you do, please see if they can provide some assistance so this pair of ospreys have a safe place to nest!

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).

This Week, Play in New Jersey’s Super Bowl…of Wildlife

This Sunday, for the first time ever, New Jersey will host the Super Bowl. Millions await the drama between two evenly matched high-flying teams.

You mean the Seahawks versus Broncos in the NFL Super Bowl?

Guess again.

Try the Falcons versus Eagles in the CWF Super Bowl!

As in peregrine falcons, the fastest animal on earth, against the bald eagles, the symbol of All-American grandeur. These two “teams” have overcome incredible odds to make it to the biggest stage imaginable: the Conserve Wildlife Foundation of New Jersey (CWF) battle for the first annual state wildlife championship. The winner will be announced on Monday morning, after a week of Facebook “likes” and donations in favor of the Falcons, or of the Eagles.

All donations will help support CWF’s work on that species, with falcon support dedicated to our Jersey City webcam program and eagle support helping our statewide stewardship work. At stake is not the NFL’s Lombardi Trophy, but an extra boost in CWF’s efforts to protect one of these imperiled species and ensure its inspiring recovery continues.

Surviving the Regular Season

How did these CWF champions make it this far? From their home stadium in downtown Jersey City (and 23 other nests across New Jersey), the Falcons have soared through the season in a continued recovery from decades of struggle against opponents like DDT and pollution. The Falcons then entered the CWF playoffs with momentum, defeating the Bobcats, Terrapins, Ravens, and Fishhawks (ospreys) in succession to reach this big stage.

Their opponent, the Eagles, play the majority of their home games on the windswept Delaware Bayshore, but also play at 118 other nests across the state. Like the Falcons, the Eagles had decades with seemingly no hope because of DDT and a rapidly changing landscape. Yet the Eagles bounced back with an inspiring few seasons, capped by victories over the Bog Turtles, Plovers, Tigers (salamanders), and Dolphins.

Among the teams that continued struggling this season were the Rattlers, the Bats, the Tree Frogs, the Skippers (butterflies), and the Goldenwings (warblers). Conversely, the Seals and Snowy Owls had strong winter seasons. Two closely rivaled teams, the Red Knots and the Horseshoe Crabs, overcame the loss of their stadium to Hurricane Sandy with a newly built New Jersey home that greatly improved their odds of success.

Now that the game is on – what are the rules for the CWF Super Bowl?

• Our field goals are Facebook comments and emails to us noting your choice (3 points each).
• Extra points are Facebook likes and Twitter retweets (1 point each).
• Touchdowns are likely to decide the winner, at 7 points per $20 in donations.

Do you win, too, if you support the winning team?

All supporters of the winning team will be eligible for a drawing to join a banding of the winning raptor this summer, with eligibility weighted by donations and points – the greater the donation or support, the greater your chance of winning! But EVERYONE is eligible, even for as simple as a Facebook like!

As for you non-football fans out there…just as the NFL Super Bowl attracts attention far beyond regular football fanatics, our CWF Championship is meaningful to all of us who care about imperiled wildlife in New Jersey. Here is a chance to ensure that a magnificent raptor – a bald eagle or a peregrine falcon – continues to grace New Jersey’s skies. Either way, score a win for New Jersey’s wildlife!

So consider this the opening kickoff! Getting out on the field is as easy as clicking a link in this email – but choose wisely. The champion awaits!

• Make a donation for your team! (make sure to note which team you’re supporting)
• Follow the “game” on Facebook
• Retweet us @wildlifenj on Twitter and use the hashtag #njfalcons or #njeagles to support your team!

Through our annual Women & Wildlife Awards we recognize women who represent a broad range of wildlife protectors in our state:

• Tracy Leaver, who rehabilitates orphaned and injured animals, including bobcats and bears;
• Linda J. Mead, who has a distinguished record in permanently preserving over 15,000 acres of natural habitats, farms, and open space for New Jersey’s wildlife;
• Jo Ann Frier-Murza, who played an important role in protecting our most charismatic wildlife as part of the New Jersey Division of Fish and Wildlife;

Update on the Merrill Creek birds.

by: Larissa Smith, Wildlife Biologist/Volunteer Manager

Back in February I gave an update on the Merrill Creek birds that had been fitted with transmitters.  https://conservewildlifenj.org/2013/02/01/tracking-eagles-in-nj/

We continue following the movements of the female that had the transmitter placed on May 29th, 2012. She spent the winter down at the Delmarva Penninsula in coastal Virginia and then headed up north and spent a large portion of the summer in Maine. She is starting to head south and on September 2nd was in Connecticut.

On May 31, 2013 the largest of three chicks at the Merrill Creek Reservoir nest, a female, was fitted with a transmitter.

This transmitter is different than the ones previously used in that it uses GSM technology. Instead of using satellites to pick up the bird’s location, the transmitter will transmit data via cell phone towers. The data is then transmitted over the internet and delivered as an email to a mobile device or computer. This new technology transmits more data, costs less and allows users to have instant access to the data through smart phones or computers. Since fledging this bird has been on the move spending time in NY, PA and back to NJ and as of September 3rd was back near the nest site.

To follow both these eagles movements  go to: http://www.merrillcreek.com/eagletracking.html.

 

by Larissa Smith, Wildlife Biologist/Volunteer Manager

Eagle Project Volunteer Tom McKelvey captured this photo of one of the juveniles that fledged from the Shark River eagle nest in mid-June.  So far this nesting season 157 young eagles have fledged from NJ nests. The juveniles will remain in the nest area for the next few months while they develop their flight and hunting skills.

 

 

LOOKING FOR HELP FROM BIRDWATCHERS TO FILL-IN DATA GAPS

By Michael Davenport, Marine Species & GIS Programs Manager

Conserve Wildlife Foundation staff work with the New Jersey Endangered and Nongame Species Program (ENSP) to manage and populate the state’s official database of rare wildlife, known as Biotics.  Currently, this database contains over 35,000 animal and plant records within New Jersey.  ENSP and CWF currently collect and enter data for the state’s 173 endangered, threatened, and special concern species.

There are several species of birds for which more observation data would be useful; and it’s likely that birdwatchers or other nature watchers may have the data needed.  Most good birdwatchers keep logs of what they’ve observed, when, and where.  It would be helpful if anyone with detailed observation data for the species listed at the end of this blog could submit their data for potential inclusion in the Biotics database.

To submit your observation data, please complete a Rare Wildlife Sighting Report Form.  The form is available on ENSP’s website for download as well as instructions for completing the form (a map must be attached when submitted).  In addition to the species listed below, please feel free to submit one or more forms for any of the state’s endangered, threatened, or special concern species.  A complete list of all of the species tracked by the state can be downloaded here.

If you have a large amount of data to submit, please contact Mike Davenport of Conserve Wildlife Foundation at (609) 292-3795 – alternative data submission options may be available (such as submitting Excel spreadsheets or GIS files).

Barn Owl (Tyto alba)
Nashville Warbler (Oreothlypis ruficapilla)
Saltmarsh Sparrow (Ammodramus caudacutus)
Sharp-shinned Hawk (Accipiter striatus)
Spotted Sandpiper (Actitis macularius)
Whimbrel (Numenius phaeopus)
Winter Wren (Troglodytes hiemalis)
