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”
Dedicated volunteers help reduce mortality of adult female terrapins
by Ben Wurst, Habitat Program Manager
Volunteers Elizabeth and Courtney measure the height of a female terrapins carapace.
Now that Northern diamondback terrapins (Malaclemys terrapin terrapin) are officially considered a nongame species, our work to help conserve breeding adult females is more justifiable. Before July 2016, adult terrapins, including egg bearing females, could be harvested during an open season from November to March. With that said, it was troublesome to know that a 15+ year old female that you helped safely cross a road in summer, could be harvested, shipped to Asia and eaten only a few months later… Now, we can rest (somewhat) easy knowing that the hard work of our dedicated volunteers will live on and help the population grow (there are still many threats to terrapins including collisions with boats, vehicles, poaching, drowning in ghost crab pots, etc…) Continue reading “Reducing Roadkills of Terrapins in S. Ocean County”

January kicks off bald eagle nesting season in the Garden State, and biologists from CWF and the Endangered and Nongame Species Program are working with volunteers across the state to monitor the nests of approximately 150 bald eagle pairs – up from 1 nesting pair just a few decades ago!
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.

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.

In Part I of this series, I discussed the drastic loss of grasslands in New Jersey and the importance of preserving and restoring this disappearing habitat for grassland-dependent bird species. Due to this habitat loss, in much of the northeastern United States (including New Jersey) airports have become significant breeding grounds for many threatened and endangered grassland birds. In fact, airports are often the only suitable habitat available for New Jersey’s rarest grassland bird, the upland sandpiper. If these large expanses of open fields are managed properly, they can support nesting birds while still remaining safe for aircraft operation. This is the goal of CWF’s new restoration project at one of the most critical breeding sites in New Jersey.

The Joint Base McGuire-Dix-Lakehurst (JBMDL) in central New Jersey hosts the largest known breeding colony of the endangered upland sandpiper (Bartramia longicauda), and the second-largest known breeding colony of the threatened grasshopper sparrow (Ammodramus savannarum) in the State. The bobolink (Dolichonyx oryzivorus), savannah sparrow (Passerculus sandwichensis), horned lark (Eremophila alpestris) (all threatened) and eastern meadowlark (Sturnella magna) (special concern) all make a home here as well during the nesting season. CWF has partnered with the U.S. Fish and Wildlife Service to restore hundreds of acres of this vital land to increase suitability and to alter management practices to benefit both wildlife and airfield operations.

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.
