Proposal to remove the bald eagle and osprey from NJ’s list of endangered species

The Murphy Administration is proposing to remove the bald eagle and osprey from the state’s list of endangered species, reflecting decades of work to restore these iconic birds to New Jersey’s landscape, Environmental Protection Commissioner Shawn M. LaTourette announced.

The proposed de-listing is contained within a Department of Environmental Protection rule proposal published this week in the New Jersey Register and is based on a finding that populations of these birds have recovered to the point where the survival of these species in the state is no longer in jeopardy.

“The de-listing of eagles and ospreys is a milestone in the history of wildlife conservation in New Jersey and is a testament to the dedication of DEP professionals and volunteers who over the years stood watch over nests in all forms of weather, nurtured hatchlings, and worked tirelessly to educate the public about the importance of sustaining wildlife diversity,” said Commissioner LaTourette.

“Because of their efforts, people across the state today can thrill at the sight of bald eagles gliding above their massive tree-top nests or ospreys diving into a coastal creek to snare a fish,” Commissioner LaTourette continued. “While we celebrate these successes, we must remain vigilant in ensuring that these species continue to thrive and be ever mindful that endangered species continue to need our help.”

“The recovery of these species from near extirpation during the 1980s in New Jersey is a dramatic example of what is possible when regulations, science, and public commitment come together for a common purpose,” said David Golden, Assistant Commissioner of NJDEP Fish & Wildlife.  “With focused attention on other species of greatest conservation need, future recovery success stories are also possible.”

Under the New Jersey Endangered and Nongame Species Conservation Act, which celebrated its 50th anniversary this past December, NJDEP Fish & Wildlife’s Endangered and Nongame Species Program (ENSP) is responsible for protecting threatened, endangered and nongame species.

Watch NJ Wildlife Virtually

I posted earlier this week about finding places to watch wildlife in New Jersey, but not everyone can get ot to those places. Though it is a very different experience - and you should get outside when you can - but can do some virtual wildlife watching in New Jersey.

Catch birds in real-time action with these web cam feeds.

How long have eagles been nesting at Duke Farms? The eagle nest at Duke Farms was discovered by staff in the fall of 2004. In the fall of 2012, Hurricane Sandy’s 70+ mph winds tore off the upper half of the nest tree, destroying the nest completely. The pair built a new nest 100 feet south of the original site in late December 2012, which is still actively used. The nest is located in an American Sycamore tree in a restricted area of the property The nest is about 80 feet off the ground. The camera can be maneuvered remotely to pan, tilt and zoom.

See dukefarms.org/eagle-cam/ and the on YouTube 

Wildlife viewing virtually or in person varies by season. For example, the nest at Duke Farms this year was most active on these dates:
Egg 1: January 20, 2023, 4:08 pm
Egg 2: January 23, 2023, 3:05 pm
Egg 1 hatched: February 27, 2023, ~2:15 pm
Egg 2 hatched: February 28, 2023, ~2:20 pm

The Osprey Cam at Long Beach Island

We posted earlier this week about the Conserve Wildlife Foundation of NJ peregrine falcon camera in Elizabeth, NJ, and today we feature their Barnegat Light Osprey Cam. 

The camera at this tall nest gives us a look at this third year for this pair of ospreys at this nest site (second year of cam).  

In 2018, they produced two young, three in 2019, and three in 2020. All young have been banded for future tracking. 

The osprey (Pandion haliaetus carolinensis) is a large bird of prey, which is sometimes referred to as a “fish hawk.” They are found in open areas and nest near water, where they find their main food source, fish. In New Jersey, most ospreys nest along the Atlantic Coast from Sandy Hook to Cape May and then west along the Delaware Bayshore to Salem with less frequent nests along the Delaware River and in Northern Jersey.

Their website states that "ospreys are an important bioindicator species and reflect the health of their surrounding environment. A healthy coastal ecosystem equals a booming shore economy and the ospreys indicate that we're doing a good job of protecting our coastal areas. There are still many threats to ospreys, even though they have recovered from the effects of DDT and habitat loss."

You can help too.
Reduce your dependence on single-use plastics.
Purchase sustainable/local caught seafood.
Don't release balloons which often end up in waterways and mimic food.
Join in a coastal cleanup and
pick up plastic litter that you see near the ocean and waterways.


You can also check out the weather at Barnegat Light at their weather station.

And you can donate to the Foundation to help them continue
to conserve wildlife and educate in New Jersey.

Eagle Scout project helps ospreys at Cheesequake State Park

One Cedar Grove Boy Scout, Dylan Green, chose for his Eagle Scout project chose to help a bird species other than an eagle that is also threatened in New Jersey. He coordinated the construction and installation of three osprey nesting platforms in Cheesequake State Park in Old Bridge.

Dylan had an earlier interest in raptors having brought orphaned birds to the Raptor Trust wild-bird rehabilitation center in Long Hill Township.

Ospreys are the only water-based raptors in America. These "fish hawks" are one of New Jersey’s largest raptors. They are well known and highly visible along coastal marshes. When hunting, they can completely submerge in water for fish which makes up almost all of their diet.

Ospreys winter in southern Florida and South America, but return to their previous nesting areas north to breed.

Another species, like the eagle, that has been threatened by the past use of certain pesticides and loss of their natural habitat, the osprey is a threatened species of wildlife in New Jersey.

Listed as endangered in New Jersey in 1973, the osprey’s status rose to “threatened” in 1986 due to an increase in pairings increased from about 50 to more than 100. And our coastal sightings in NJ for 2017 were at 668 pairings.

Dylan worked with Ben Wurst, a habitat program manager for the Conserve Wildlife Foundation of New Jersey. Environmentalists began providing platforms for nesting in the 1970s and today about 75 percent of the state's ospreys nest in platforms.

The nesting areas have a 3-foot perch for the birds on 16-foot posts. Like many Scout projects, Dylan had many helpers. Major Hardware, a Cedar Grove store, donated all the hardware and
West Essex Building Supply Co. in nearby Verona discounted the lumber. The project cost still amounted to $1400 for the three platforms.

Birds and Airports. Not Perfect Together.

United Airlines and Audubon International are teaming up to protect raptors “threatened” by living near Newark Airport. They want to send them to nearby golf courses.

The United Eco-Skies Raptor Relocation Program at Newark Liberty International Airport plans to protect hawks, ospreys and owls by transporting the animals to golf courses certified within the Audubon Cooperative Sanctuary Program.

Since a 2009 accident when a jetliner was forced to land in the Hudson river after birds were sucked into its engine, many birds have been killed in the New York City area in an effort to make flight paths safer.

"The presence of wildlife at our airports can pose a challenge to pilots operating commercial aircraft," said Laura Francoeur, the Port Authority's chief wildlife biologist. "The agency implements wildlife management measures to reduce these challenges, and we continue to work with our airline partners and organizations such as United and Audubon International to ensure safe operations while protecting nature."

But, according to GooseWatchNYC.com, the leading causes of fatal plane crash accidents are not wildlife but pilot error (50%), mechanical error (22%) and weather (12%).

NJ Webcams

There are a good number of webcams online that let you peek at parts of the state.

You can watch folks on the quiet end of the boardwalk at Seaside Park, or move north to the livelier boardwalk in Seaside Heights, or much further north to the Great Falls in Paterson.

EarthCam and the Friends of Island Beach State Park set up a live streaming look at an osprey who calls Island Beach State Park. Island Beach is one of New Jersey's last significant remnants of a barrier island ecosystem that once existed along much of the Atlantic coast. That webcam has been more off than online this summer, but you can check it out at  earthcam.com/usa/newjersey/islandbeachstatepark/osprey/

Reports on 3 New Jersey Raptors

An osprey returns to its nest     Photo by Gary Lehman

Raptors, commonly referred to as "birds of prey," include hawks, owls, eagles, falcons and vultures. Raptors have fascinated people for thousands of years and inspire people even today. Fortunately, after some frightening declines in some of our largest species, raptors represent some of New Jersey's greatest success stories.

The bald eagle, osprey and peregrine falcon have made impressive comebacks from the brink of extinction, in large part thanks to the efforts of division biologists.

Unfortunately, not all species of raptors are thriving - the American kestrel, for instance, has experienced a sharp decline in recent years, and the work of biologists in the Endangered and Nongame Species Program continues.

The 2014 reports on three raptor species managed by the NJDEP Division of Fish and Wildlife have been posted on the Division's web site. The reports detail the management efforts and results of Division staff and dedicated volunteers.

This work would not be possible without public support. Donations to the program can be made on the NJ state income tax return (Line 58 - check-off for wildlife) and through Conserve Wildlife License Plates.

New Jersey Osprey Project

days old osprey at Great Bay

The osprey was listed as an endangered species in 1973 and quickly after that the New Jersey Osprey Project began.

Starting with a spring 1974 aerial survey to determine the number of active osprey nests from Toms River to Atlantic City, the results were not good.

With a baseline historic count of 500 osprey nests, it was expected that the numbers would be down due to the effects of DDT and habitat loss and in the 1974 count only 50 nests remained.

New Jersey habitat was also lost because of a growing shore population. New construction eliminated trees needed for nesting and it increased the ground predator populations.

The project began to supply man-made nest platforms for the birds to replace snags and trees that lost to development on the barrier islands.

DDT in the food chain caused reproduction to fail. DDT was banned in 1968, but the negative effects and residual DDT continued for a number of years. Used in and near marine environments, it was absorbed by both organisms and soils and accumulated in the food chain. Because DDT is fat soluble it bioacummulated in predators, especially birds of prey.

It did not kill the birds, but rather caused the thinning of eggshells which often broke under the weight of the incubating female.

3 young
By 1986, the osprey population had surpassed 100 pairs. This allowed their status to be changed to "threatened"in NJ.

During that time, some of my volunteer work for the Endangered and Nongame Species Program involved monitoring and tracking nest success.

2006 found the NJ osprey population at a new post-DDT high of just over 400 active nests, and that was surpassed in 2009 with 486 nesting pairs.

The next aerial survey was scheduled for this year.

New Jersey's osprey population, like osprey populations throughout the country, was in serious decline from the 1950s through the 1970s due to the effects of DDT and other widely used pesticides. However, in the past few years, the osprey population has finally climbed back to its pre-DDT levels. The NJDEP Division of Fish and Wildlife's Endangered and Nongame Species Program has worked with volunteers fostering this comeback through nest management and the placement of nesting platforms.

The work of one group of volunteers, Citizens United to Protect the Maurice River, was recently highlighted on the Newsworks website, the online home of WHYY News and its network of journalism partners in Philadelphia, South Jersey and Delaware.

Spring Must Be Near

Robins on your lawn might be your sign of spring, but a post on the NJ Osprey Project blog reminds me that adult ospreys begin heading north in the first weeks of March.

Volunteers with the NJ Osprey Project help install an osprey platform

In the northeast U.S., Ospreys migrate south, from September to early November, to winter in the Gulf States, Florida and Central America. Ospreys return to the same nest site year after year, and young adults return to where they originated to reproduce when they are 3 years old.

Ospreys usually live till around 10 years old in the wild. The oldest osprey that was ever encountered in New Jersey was a female that was 18 years old.

OSPREY -  U.S. Fish and Wildlife Service

Osprey are large (22”-25” in length) black and white fish-eating raptors, with a bold white forehead and eyebrow, and a wingspan of 58”-72” inches.

Both males and females are similar, but females generally exhibit more spotting (a “necklace” of spots) on the breast than males and are generally a little larger. In flight, they hold their wings back in a characteristic “M” shape.

Ospreys nest in tree tops, poles, towers, stubs, sometimes roof tops, chimneys, navigation buoys, rock pinnacles, stick piles, and even on the ground, but never far from water. Nesting material includes sticks, grass, seaweed and clods of mud.

The adults return year after year in early March to rebuild and add material to the nest. Some nests are occupied every year for 40 or more years by a succession of birds and reach a depth of over 10 feet. Fledglings leave the nest after about 8 weeks from their hatch date.

2010 Osprey Information for NJ

Ospreys are well-loved birds of our coastal bays and marshes. Formerly known as the fish hawk, ospreys rely almost exclusively on fish for their diet. They have taken well to human structures, such as duck blinds and channel markers, for nest structures. They, like eagles and falcons, succumbed to the effects of DDT and their population dropped to about 60 pairs by the early 1970s.

With the help of biologists and, more recently, volunteers who put up nest structures, they have recovered to more than 360 nesting pairs. The Endangered and Nongame Species Program monitors their health as an indicator of many coastal species, as they are sensitive to contaminants and the viability of the aquatic food chain.

Very Productive Year for Osprey in NJ

Checking a nest at Great Bay Blvd. WMA, Little Egg Harbor - photo by Bill Steiner

2010 was a very productive year for ospreys in New Jersey, according to the latest Osprey Project report.

The reproductive rate was about 2 young per active nest (an all time high for the project). Calm weather contributed to the success as it makes prey easier for ospreys to find, especially fluke and flounder, one of their main prey sources.

Of the 308 active nests (where the outcome was known) 36% of nests had 3 young, 33% had 2 young, and 14% had one young. Only 11% observed had failed to produce young. For comparison, in 2006, 14% failed and in 2003, 46% failed.

    Early Results of Osprey Surveys Are Encouraging

    Photo: Ken Connelly  via http://njospreyproject.blogspot.com/
    Ospreys are currently listed as a threatened species in New Jersey. They were first listed as endangered in 1974 after the state population declined to only 50 pairs, from over 500 prior to 1950.

    As with eagles, ospreys have made a dramatic recovery in New Jersey because of efforts by state biologists with the Endangered and Nongame Species Program (ENSP) and many volunteers.

    Ospreys are predators and so they are considered to be an indicator species. These species are sensitive to changes in environmental conditions and can serve as an indicator of an unhealthy marine ecosystem.

    Surveys to monitor the population are conducted in late June and early July at all major nesting colonies from Sandy Hook south along the Atlantic Coast to Cape May and west to Salem County.

    In NJ, ospreys almost exclusively nest on man-made structures including platforms designed specifically for them, cell towers, duck blinds, channel markers, and boat lifts.

    The surveyors check nest structures for birds and, if the nest is occupied, the number of young is recorded and the young are banded for future tracking with a USGS bird band.

    Though the results are preliminary, productivity rates appear to be up for all nesting colonies except for Sedge Island WMA.

    For more information and survey results later this fall, see http://www.conservewildlifenj.org and http://njospreyproject.blogspot.com.

    The New Jersey Osprey Project


    I recommend that you check out the New Jersey Osprey Project blog done by Ben Wurst. Ben is listed as a Habitat Program Manager in New Gretna, NJ.

    The blog has lots of information and some great photos from the field (see examples above and below).

    A recent post covered the June start of the first of many osprey surveys which are conducted every year to help determine the overall health of the population.

    This is another activity that is mostly done by volunteers who commit many hours of their personal time to helping monitor the bird population.

    USGS leg bands are placed on the young which enables scientists to gather valuable data about where ospreys migrate and winter, their survival rates and behavior.

    On the Banks of the Old Raritan


    Albany Street Bridge over the Raritan in New Brunswick

    Having spent four years at Rutgers College, I heard and sang the alma mater plenty of times at events. "On the Banks of Old Raritan"  (listen to it too)was more than a song in those years, because I spent a lot of time on the actual banks of the river and staring at it from my river dorm window (and flying some masterfully made paper planes over it to Johnson Park).

    And so I settled down,
    In that noisy college town,
    On the banks of the old Raritan.


    The River Dorms


    The Raritan River is New Jersey's largest river that is entirely contained in the state.

    Its watershed drains much of the mountainous area of the central part of the state, emptying into the Raritan Bay on the Atlantic Ocean. There are 1,100 square-miles of rivulets and streams that spill into the Raritan. The river's source is Budd Lake in the more rural northwestern part of the state. Its path through the state takes it through 100 municipalities and seven counties to an industrial end in Middlesex County.

    The Raritan River forms at the confluence of the North and South Branches just west of Somerville. It flows 16 miles before slowing in tidewater at New Brunswick. Its estuary extends 14 miles more until the Raritan Bay at South Amboy.

    So, naturally, there would be some further Raritan and Rutgers connections. The Sustainable Raritan River Initiative is one where Rutgers and the over thirty partner organizations and businesses are collaborating to restore and revitalize the Raritan River.


    The threats facing the Raritan include over 150 significantly contaminated sites, the legacy of its industrial heritage, and stormwater runoff that erodes riverbanks and brings trash and pollutants into the waterway, the legacy of antiquated infrastructure in a highly urbanized region.

    The lower watershed, cited as 14th among US rivers polluted by direct and sewer discharges of toxic chemicals (from 1990-1994), has been heavily impacted by intense industrial and storm runoff pollution and heavy flooding due to extensive urban impervious surfaces and climate change.

    But the Raritan River basin also has spectacular natural areas, wildlife habitat, trails and recreational boating areas. It also has scenic waterfront redevelopment opportunities that create the potential for long-term balance and sustainability for the River and the towns that border it.


    Some History
    The Raritan River was an important water transportation route for the Native Americans. The “Raritan” was an Algonquin word meaning “stream overflows.” The Raritan people were also an Algonquin tribe.

    In colonial days, early industry around developed along the Raritan around New Brunswick. During the Revolutionary War, the river provided a means for troop conveyance.

    However, before the American Revolution, early Dutch settlers built grist mills on the Raritan, called the “Forked River” by Native Americans.

    In the 1830s the Raritan-Delaware Canal provided a waterway connecting Philadelphia and Pennsylvania’s coal fields to New York.

    The Lower Raritan Watershed’s environmental health has rebounded over the past decade, but there is a long way to go. Bald eagles, peregrine falcons, and osprey again soar the Raritan skies, and a thriving fish population has helped seals, otters, and marine life recover here.

    The Edison Wetlands Association (EWA) Raritan River Project has fought since 1989 for the cleanup and restoration of the hazardous waste sites posing the greatest threats to human health and environment.

    The Lower Raritan Watershed has a disproportionate amount of the NJ 25,000 toxic waste sites draining into its watershed. Most of these are not remediated to levels that are protective of human health or the environment. Federal and State regulatory agencies responsible for cleaning up these sites have abdicated their responsibilities and the pollution remains unchecked. Over-development threatens the remaining natural areas along the Raritan and her tributaries.

    To end on a positive note, the relatively pristine Upper Raritan is a habitat for endangered ancient wild brook trout. It is challenged by an excessive deer population that is seriously reducing vegetative and forest renewal and by the need to preserve its farms and open space.

    “Ode to the Raritan, Queen of Rivers”
    by John Davis, 1806

    All thy wat’ry face
    Reflected with a purer grace
    Thy many turnings through the trees,
    Thy bitter journey to the seas,
    Thou Queen of Rivers, Raritan!

    2009 NJ Raptor Reports Available


    The 2009 reports for three raptor species actively managed by the NJ DEP Division of Fish and Wildlife's Endangered and Nongame Species Program are now available online. The reports for Bald Eagle, Peregrine Falcon and Osprey summarize management efforts, species status and results of this year's nesting season.

    This year, there was a record number of 84 Bald Eagle pairs, which resulted in 69 active nests producing 99 eagle fledglings.

    The number of Osprey nesting pairs recorded was 485; a 14% increase since the 2006 survey.

    Peregrine Falcons increased also to 24 nesting pairs in 2009.

    Visit http://www.njfishandwildlife.com/ensp/raptor_info.htm on the division's website for more information on these species and to view the 2009 reports .

    Vitual Wildlife Viewing


    With the weather not being that great in NJ for many people walking in the woods, it might be a good time to consider some virtual wildlife viewing.

    It a quick click to visit the raptor cams at Blackwater Refuge in Maryland. Every season since 2001, they have operated the Osprey Cam and allowed visitors at the Refuge, and on the Friends of Blackwater website, to witness the miracle of seeing numerous osprey chicks hatch and fledge.

    Due to the overwhelming success of the Osprey Cam, the Friends decided to mount a camera over an active bald eagle nest on the Refuge property beginning in 2004. The live Eagle Cam has proven even more popular than the Osprey Cam, and numerous eaglets have hatched and fledged on the cam.

    The Eagle Cam is live from December through July (when the eagles are at the nest), and the Osprey Cam is live throughout the year, even though the ospreys are only on the nest from March through September. After the ospreys migrate to South and Central America in the fall, bald eagles take over the osprey platform and use it as a riverside perch, so the Friends leave the Osprey Cam on all year to allow cam watchers to see the visiting bald eagles.

    Go to www.friendsofblackwater.org/camcentral.html

    NJ has webcams too - for example, the eagle cam at Duke Farms will be active again in March, but check out some of their archived videos.

    Osprey in New Jersey

    ospreyOsprey, Sandy Hook - photo by Brian Richards

    The osprey (Pandion haliaetus)) is a large raptor (bird of prey) usually seen near bodies of water that support adequate fish populations. In the 1800s, there was an abundant breeding population of osprey along the New Jersey coast and near most fresh water bodies.

    Pesticide contamination and habitat loss gradually reduced the annual number of osprey nesting pairs throughout this past century. In fact, osprey populations plummeted from 500 pairs in the 1950s to 68 pairs in 1975. The species became one of the first to be included on the New Jersey Endangered Species List.

    The osprey has a wingspan of 4.5 – 6 feet. It glides with its long, narrow wings pulled towards the body and, when viewed from the ground, resembles the shape of the letter "M".

    They feed on fish and inhabit coastal rivers, marshes and bays, as well as rivers, lakes and reservoirs. They are known for their feet-first plunge into the water to catch their prey with their talons that have spines on them to pierce the fish's skin.

    Ospreys nest on live or dead trees, manmade nesting platforms, light poles, channel markers and other elevated structures that offer an unobstructed view of the landscape near and around a water body.

    Historically, the number of reproductive osprey pairs began to decline in the 1900s due to habitat loss, the eradication of nest trees, egg collecting and shooting. This was compounded by increased human settlement along the coast later in the century.

    Between 1946 through 1964, the pesticide DDT was introduced into the environment to combat mosquitoes. It entered the food chain and eventually contaminated predators like the osprey. The chemical did not kill the birds as people often believe, but weakened the thickness of osprey eggshells, which would break under the weight of the bird during incubation. They can experience reproductive failure over a long period of time because DDT contamination can remain in an adult osprey's body for years.

    Starting in 1979, the Endangered and Nongame Species Program transplanted eggs from healthy nests in the Chesapeake Bay area into New Jersey nests. Program staff also erected nesting platforms and began annual surveys to monitor osprey productivity.

    The state's osprey population began to recover as nesting success improved and the number of nesting pairs increased each year.

    Due to its improved reproductive success, its acceptance of manmade nesting structures and the decline of persistent pesticides, the status of the osprey in New Jersey was changed from endangered to threatened in 1985. They were the first species to be removed from the list.

    Department biologists and volunteers counted 340 nests in 2001 and banded 201 young osprey in their nests in 2002.

    The state currently conducts an aerial survey of the state's osprey population every two years. They observe nests yearly and band many of the young osprey chicks while they are still in the nest.

    The Osprey Project in New Jersey reported that 38 new nest structures were erected or discovered in 2008: more than half (21) were occupied, and fourteen produced 25 young.

    In typical fashion for NJ (and the East), most ospreys nested on man-made single-post structures (77%) and channel markers (5%), while only a few nested on antiquated 4-post nest platforms (3%). The occurrence of ospreys nesting on cell towers (1%) fluctuates from year to year, but that’s a structure favored by inland-nesting ospreys. Other nests can be found on transmission towers (3%), duck blinds (3%), and in dead trees (2%).

    Ospreys get very creative in areas of the state where nest platforms are limited. They will try to build nests on many different structures including lighting poles on sports fields, weather stations, telephone poles,cranes, houses, and almost anything tall and stable.

    The NJDEP works closely with the Conserve Wildlife Foundation of NJ (CWF) to use private donations to fund nest platform and habitat restoration projects along the Atlantic Coast. In the last three years, over forty nest platforms have been built and installed with private donations to CWF.

    The next statewide census is scheduled for this year and will attempt to count all active nests during aerial and ground surveys.
