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).

Several Delaware Bay beaches will be closed from Monday, May 7 to Thursday, June 7, 2012.  Beaches are closed to protect a rapidly-declining population of migrating shorebirds including the red knot which is an endangered species in NJ.  But this doesn’t mean that you can’t come out and view the shorebirds and horseshoe crabs. It’s the prefect time to see these birds undisturbed and feeding on horseshoe crab eggs.

Several beaches are set-up for shorebird viewing including Reeds Beach, Norburys Landing, Kimbles Beach and Cooks Beach in Cape May County. Find more viewing locations on our interactive Wildlife Viewing Map.

Shorebird Stewards will be present at closed beaches to educate the public about the interaction between the shorebirds and horseshoe crabs. Take some time this May and come visit the Delaware Bay and enjoy the view!

AMERICAN OYSTERCATCHERS TAGGED AND READY FOR MIGRATION

TRACKING THEIR PATH AS THEY HEAD SOUTH FOR THE WINTER

Throughout the fall, there is a remarkable sight to see along New Jersey’s coastline.  Thousands of shorebirds group together in huge flocks, using our state’s coastline as a migration stopover point to rest and feed.  One particularly interesting shorebird is the American oystercatcher, which is listed as a species of special concern in New Jersey.   At the Conserve Wildlife Foundation of New Jersey, we work with biologists from the New Jersey Division of Fish and Wildlife to survey these birds throughout the fall season.

The oystercatcher is an especially easy bird to survey during fall migration due to its distinct features. Not only do they stand apart from other shorebird species with their unique orange bill and striking coloration, but color bands help us determine individuals as well.  Banding efforts have been underway in New Jersey since 2004 in order to give insight to researchers regarding the
oystercatcher’s breeding habits, pair behavior, and migration patterns. About 300 oystercatchers have been banded in New Jersey to date, including a significant percentage of the state’s estimated 400 breeding pairs. (more…)

BANDED PIPING PLOVER CONTINUES TO DEFY EXPECTATIONS

by Todd Pover, Beach Nesting Bird Project Manager

Some of you may recall an earlier blog (If At First You Don’t Succeed, Try, Try, and Try Again, July 27, 2011) posted by Emily Heiser, one of our seasonal technicians, in which she

"Bahama Mama" - If You Look Close, You Can Detect The Color Bands On her Legs

reported on a piping plover that had nested four times this

year. One reason we know so much about this individual bird is because it is one of just a few banded piping plovers found in New Jersey-it was originally banded in the winter of 2010 in the Bahamas.

This specific bird, dubbed Bahama Mama by our staff, was first observed this year at North Brigantine Natural Area on March 29. It spend the next several months finding a mate, laying and incubating eggs, and finally trying to raise young, a cycle that ended unsuccessfully near the beginning of August. Normally that would be the end of the story for this year, but because we are conducting post-breeding/migratory piping plover surveys once a week at this site through the end of October, we have more to report.

As of last week, Bahama Mama was still present at the same site, nearly two months after breeding concluded and six months after she first arrived. The fact that she has remained there well after the nesting season ended is a huge surprise and defies conventional expectations. We fully expected her to be on her way back to the Bahamas by now.

Red knot wintering population drops by more than 5,000, accelerating slide to extinction

Decline emphasizes need to list the knot under the Endangered Species Act and implement stronger protections at key U.S. stopover

Summary:

  • Scientists today released a report announcing that a decrease of at least 5,000 red knots was observed at key wintering grounds in Tierra del Fuego, Chile from the previous year. Scientists reported population counts of wintering knots in other locations declined as well. The estimated current total population for the migratory shorebird is now unlikely to be more than 25,000.
  • The decline in red knot numbers elevates the importance of implementing stronger protections at Delaware Bay, a key U.S. stopover where migrating knots depend on an abundant supply of horseshoe crab eggs to fuel the final leg of their migration to breeding grounds in the Canadian Arctic.
  • The scientists’ report concludes that despite horseshoe crab harvest restrictions put in place by the Atlantic States Marine Fisheries Commission over the past decade “there is still no evidence of recovery of the horseshoe crab population, either in numbers of spawning females or in all sub-adult age groups including juveniles.” Restrictions to date have only been enough to stop the population from declining further, are insufficient to recover the population and will continue to be insufficient unless the harvest is greatly reduced.

 

WASHINGTON (May 23, 2011) – Conservation groups are calling on the U.S. Fish and Wildlife Service (FWS) to take immediate steps to list the red knot under the Endangered Species Act. A listing would initiate the development of a recovery plan and require federal agencies whose actions affect red knots to consult with the FWS. A listing would also require the Atlantic States Marine Fisheries Commission, housed under the National Marine Fisheries Service, to consult with the FWS on the regulations it establishes for the horseshoe crab fishery. The following are statements from groups pursuing an endangered species listing:

“It’s simple, to halt this decline and imminent extinction, we must list the red knot now and view all shorebird protection through the same lens,” said Margaret O’Gorman, executive director for Conserve Wildlife Foundation.

“This year’s huge decline in wintering red knots provides clear evidence that the status quo is not working. Unless action is taken now, red knots may be on an irreversible slide to extinction,” said Bob Irvin, senior vice president for conservation programs at Defenders of Wildlife. “The U.S. has a responsibility to the global community to protect this migratory shorebird, which stops along our coast to rest and feed while making one of the longest migrations in nature, from the tip of South America to the Arctic.”

“The bad news demands we redouble our efforts to rebuild the horseshoe crab population of Delaware Bay,” said Tim Dillingham, Executive Director of the American Littoral Society. “A listing of the red knot under the ESA will allow for management of the horseshoe crab population to be directed toward recovery of the shorebird populations, and not simply the local fishing interests. We urge the USFWS to make this a priority.”

“Until recently, the Delaware Bay resplendent with spawning horseshoe crabs and over a million shorebirds was the land of plenty – our Serengeti,” said Eric Stiles, vice president for Conservation and Stewardship for New Jersey Audubon Society. “The red knot is one of the shorebirds whose very existence is teetering on the brink of survival. Unlike special interest naysayers, we have full faith in the Endangered Species Act. Only through listing will the robin-sized, chestnut colored shorebird be enjoyed by future generations.”

“The decline of the shorebirds and the horseshoe crabs that sustain them is not speculation; it is a proven reality documented by science and history. The Atlantic States Marine Fisheries Counsel, among those charged with protecting the species, has ignored the science and the harm in order to assuage their political allies. In the absence of strong and earnest action from the ASMFC, we need strong action from our states. While New Jersey has taken that strong action to protect the crabs and the birds, Delaware’s actions leave a lot to be desired when the politics heats up” expresses Maya van Rossum, the Delaware Riverkeeper.

“The rufa red knot, which once darkened the skies during their migration, now stands on the very knife-edge of extinction. The states along the east coast, with the exception of New Jersey, dithered for decades and now the only way to save this subspecies is for the U.S. Fish and Wildlife Service to place it on the Endangered Species List. With this new report, it is clear that if the federal government doesn’t act soon, the next generation of Americans will never see this amazing long-distance migrant. People who want to see this bird in the wild best make plans in the near future because the way things are going, it will be gone sooner rather than later,”  said Darin Schroeder, Vice President for Conservation Advocacy for ABC.

“A population decline this large and this rapid is almost unequalled in our lifetime,” said Greg Butcher, Director of Bird Conservation for National Audubon Society. “Surely such a bird requires the immediate protection of the Endangered Species Act and needs to be a top conservation priority for all of us.”
