We were subcontracted by NJDOT to install a new nesting tower for peregrine falcons in Stafford Twp., Ocean County. We’ve assisted NJ Fish & Wildlife with monitoring the falcon nest that was previously located beneath the Route 72 Causeway Bridge for the past several years. The new tower is located on Bonnet Island and highly visible on the eastbound side of Route 72. Continue reading “Photos From the Field: Bonnet Island Falcon Tower”

CWF will be at the festival on February 3rd. There are presentations, walks, viewing sites and exhibitors. It’s a great way to learn about NJ’s eagles and other raptors.
Nests on towers and buildings maintain stability in the state population

Results from the 2017 nesting season for peregrine falcons was released in a report from New Jersey Fish & Wildlife’s Endangered Species Program, and falcons had a decent year. New Jersey’s population remained stable with 32 active nests (with 34 known pairs) as compared to last years’ results of 30 active nests (35 known pairs). Nest success was slightly better than last year, with 22 pairs producing 52 young as compared to 20 pairs producing 47 young. The productivity rate, which is a measure of the health of the population, was very close to what was observed in 2016 at 1.59 young/active nest.

Boy Scout Dylan Green gives osprey nesting platform a needed upgrade

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.
In the end of October, NJ Eagle Project volunteer Randy Lubischer spotted a banded adult bald eagle near his home in Monmouth County. He was able take good photos that showed the bird was banded with a blue (NY) band on the left leg and was able to get a very clear image of the letter and number code on the band. We reached out to the NY Division of Fish, Wildlife and Marine Resources to find out more information on the eagle.
In the fall of 2011, an injured hatch year bird was found on the side of the road in Onondaga County, NY. The bird was rehabbed, banded (NY Blue band W34) and released on October 7, 2011 at the Montezuma NWR. On 11/18/2016, W34 was sighted in Darlington, Maryland and then in in NE Maryland again on 3/1/2017.
W34& mate 11/7/17@Randy Lubischer
W34 looks to be staying in NJ to nest as he has found a mate, a sub-adult female, who still has dark feathers on her head. They have started to build a nest and have been copulating.
We can’t necessarily assume that W34 was hatched in NY. Since he was found injured and not banded he could well be a NJ bird. We have followed NJ recent fledges outfitted with transmitters, take long flights north after leaving their nest areas. We also know that many NJ banded eagles do return to NJ to nest. So we’ll never know the true origin of W34 but we can piece together some of his story and hopefully have more news about him and his mate in the upcoming nesting season.
NJ Osprey Project Volunteers Wayne Russell, Matt Tribulski and John King repair an osprey platform.
New Jersey ospreys have headed for warmer climates until their return in the spring. NJ osprey project volunteers are busy repairing and cleaning out nests, adding predator guards and perches in preparation for the nesting season. It’s an endless job as there are 100’s of nesting platforms throughout the state and maintenance is always needed. These repairs keep the nests as safe as possible for the nesting ospreys.
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.
