Thanks to dedicated Conserve Wildlife Foundation of NJ staff and volunteers three osprey chicks were saved from what could have been an unhappy fate.
NJ Osprey Project Volunteers Matt Tribulski, Wayne Russell and John King were surveying osprey nests in the Wildwood back bay area this past weekend. They checked on a nest with three chicks and found that the platform top was broken and a strong possibility it could collapse, especially with any heavy rains or winds. The chicks weren’t old enough to fly and would have fallen to the marsh and died. Continue reading “Osprey Chicks Get A Necessary “Home” Upgrade”

Two volunteer groups and the Seaside Heights public works department teamed to help a baby osprey that had a balloon ribbon tangled around its leg in a nest at Island Beach State Park.
The Amazing History of a Breeding Adult Male Osprey at Island Beach State Park

Around 3% of ospreys who were banded with USGS aluminum bird bands as nestlings in New Jersey are re-sighted after fledging or leaving their nest. Most of those recoveries or resightings are centered around mortality based events where a bird is injured or killed and the band is then close enough to read. Since the numbers on the leg bands are so small, it is often hard to read when they are still alive. However, when enough photos are obtained or a camera is installed on a nest then the likelihood of reading the band on a live bird increases.

Barnegat Bay Osprey Returns to New Jersey After Two Year Vacation

04/D was photographed in Allendale at the Celery Farm by Barbara Dilger on Monday, April 23.
North American ospreys migrate long distances to and from their breeding and wintering grounds in the southern U.S., Central America, Caribbean Islands, and N. South America. For the past four years we have been banding young ospreys who originate from nests on Barnegat Bay with an auxiliary band to help determine their movements after fledging. Project RedBand was designed to help track the migration, dispersal, life span, and foraging habits of ospreys from Barnegat Bay, a unique estuary along the Atlantic Coast of New Jersey. The project was also designed to help engage the public in osprey management and conservation. Since the red bands are highly visible and readable with optics, it allows the public the ability to identify the individual and then learn about their past. Lastly, we now rely heavily on citizen scientists who report nesting activity on Osprey Watch. Continue reading “Osprey 04/D Back in Jersey!”
Male osprey makes epic return to nest along Delaware Bay; turns seventeen this summer!

Photographer Brian Kushner has photographed this bird over the past ten years. Just this past week he confirmed his return to his nest by ID’ing him by his band # 0788-45514. Click to view large on Flickr. photo by Brian Kushner.
The spring arrival of the North American osprey (Pandion haliaetus carolinensis) to their nesting grounds in New Jersey was delayed slightly due to prevalent north winds. As we saw many birds begin to arrive to their nest sites, which they return to year after year, we were particularly interested in the return of one very special osprey. This individual, if he survived the winter would be the oldest living osprey ever recorded in New Jersey to be observed on his nesting grounds. Ospreys face many threats and their life span averages around 8-10 years, but some can reach 20 years old.
We would not know how old this bird is without the USGS bird band that was affixed to his left leg before fledging in the summer of 2001. Photographer Brian Kushner, who has been watching this nest for the past 10 years, was able to photograph the band, which allowed us to track down his origins. He was banded on July 5, 2001 before he could fly. The nest was less than 5 miles away from where he currently nests along the Delaware Bayshore. Typically it is very difficult to ID birds by their USGS bird bands, and most recoveries or sightings of bands occurs during an injury or death, but Brian’s been able to use his photography equipment to positively ID this bird. Banding data shows that males return as adults to nest in very close proximity to their natal areas while females tend to wander further away to nest.
Ospreys are currently laying eggs and starting incubation, which occurs right after the first egg is laid. Nests with eggs and young are protected from disturbance during this time, and established nests cannot be removed without consulting with NJ Fish & Wildlife and USDA Wildlife Services. Please refer to our “Living with Ospreys in New Jersey” guidance document for more information.
On a cool and cloudy Monday morning, CWF Habitat Program Manager, Ben Wurst was joined by News 12 New Jersey reporter, Tony Caputo to highlight the osprey’s triumphant recovery in the Garden State. Ben was working in the field to repair a few osprey nests and complete the first of several nest checks at a nearby peregrine falcon nest. We work tirelessly to ensure that when ospreys return from their wintering areas that their nesting platform are in good condition.
Statewide Census Documents over 650 nesting pairs in New Jersey

An osprey prepares to land on a natural nest. Barnegat Bay, NJ.
Since we began to work more closely with ospreys in 2006, we have documented the population grow beyond the historic population estimate of 350-450 nesting pairs (Henny 1977) to a new historic milestone. In 2017, a total of 668 active nests were recorded during a statewide census of nesting ospreys, which is well above the post-DDT milestone of 500 nesting pairs, and show that the population continues to grow. This is the second census conducted without the use of manned aircraft since 2009 after all known osprey nests were released and mapped online in 2013. Despite the lack of aircraft, we’re still able to obtain an accurate representation of the size and health of the statewide population, while reducing the overall project cost.

Boy Scout Dylan Green gives osprey nesting platform a needed upgrade
by Ben Wurst, Habitat Program Manager
Dylan and his father John pose for a quick portrait in front of one of the new platforms.
This past Sunday we assisted Dylan Green, along with his family and fellow Troop 65 scouts to install three new osprey nesting platforms. The project was done by Dylan as part of his Eagle Scout Service Project. He self funded the project using his own money to purchase the supplies needed to construct the platforms and built the platforms together with his fellow Boy Scouts. The platforms were used to replace two platforms that were in bad condition. The third was installed in a location where a platform used to be located. The osprey population at Cheesequake State Park is small, but it is good habitat for ospreys. Continue reading “Photos from the Field: Cheesequake Osprey Platform Replacement”
Ready to release Chump. RIP, Chump! photo by Northside Jim.
I thought long and hard about sharing this news, hence the delay in this post. In late October, we received news that a young osprey I banded this summer was re-sighted. It turns out that this bird was not your average young osprey, out of the 892 produced this year. This young bird hatched at a nest behind the Long Beach Island Foundation of the Arts & Sciences, around June 11th, a nest referred to as home to “LBI’s Most Famous Osprey Couple, Jack & Wendy.”He was banded, along with his nestlings, on July 5th. He was tagged with a red auxiliary “field readable” band: 78/D, as part of Project RedBand, which allows fellow biologists and citizen scientists the ability to identify the bird while still alive (most osprey band reports occur during mortality based events). At the time of banding, he was also given the name Chump, by Northside Jim.
ACTION ALERT: Support ecological management of the most valuable public resource for our coastal ecosystem and economy

The Atlantic States Marine Fisheries Commission is accepting public comment on the establishment of ecological management of Atlantic menhaden (Brevoortia tyrannus), which is a keystone species. Basically, a keystone species is one that plays a large role in the ecosystem where it lives. If a keystone species is lost then the ecosystem would dramatically change or cease to function, causing widespread effects to other species that benefit. In New Jersey, ospreyshave largely benefited from a healthy menhaden population as we’ve had relatively high reproductive rates (more than double what’s needed to sustain population) over the past decade. From 2006 to 2016, the population has grown by 30% and above the pre-DDT, historic milestone of over 500 nesting pairs. Around 82% of the state population of ospreys nests along the Atlantic Coast and we observe menhaden at a huge number of nests during our mid-summer surveys. If menhaden numbers drop, then we will likely see osprey numbers follow suite, as reproductive rates will decline, as they are in the Chesapeake Bay.
