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.
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”

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.
Volunteers needed to help maintain and repair osprey nests

We have an obligation to care for and protect our wildlife, and for me, that’s what drew me into my current position. Osprey nesting platforms have been a focus of my work over the past 10+ years. They are designed specifically for ospreys and if built properly, can withstand the impacts of severe weather, including coastal flooding, high winds, and storm surge. For ospreys these platforms protect their nests from predators and flood tides, but over time the extreme salt marsh environment takes its toll on them. With the added weight of the large, perennial stick nests it can shorten the life span of a properly built platform drastically. Over the years I’ve seen older nests topple, from the weight of the nesting material and aging hardware, during the middle of the nesting season during severe storms. This is hard to prevent at every nest, during every storm, which we know are becoming more and more frequent, but we are adapting and in turn, helping our ospreys become more resilient (and productive) in the end.
New stainless screws are installed in an existing osprey nest to help prevent future catastrophe.
In the past we (myself and other volunteers who survey ospreys and help maintain platforms) used to visit a nest only once a year, during nesting surveys in late June and early July. At that time we would note the condition of the platform and if repairs were needed, schedule those for the seven month long non-breeding season. Those who have volunteered to help and worked with me, know the task at hand. Most tasks include using hand tools to construct nest platforms and perches and to install them. I always say the hardest part is getting the platform to the saltmarsh where they will be installed.
To help engage and inspire others to help care for our growing osprey population, we are looking for volunteers who live within the watersheds were we are planning to conduct repairs of osprey platforms. Tasks vary by watershed but most are to add new (stainless) screws to existing platforms, install predator guards/perches, clean off excess nesting material, and do any other repairs to platforms (including moving and replacing some). We are hopeful to meet some local baymen and fishermen who are looking to help keep the nesting population stable as it has been over the past 10 years.
The work will occur in mid-late October and will be carried out through these watersheds:
Barnegat Bay (Point Pleasant south to LEHT)
Great Bay – All nests here need new hardware and one nest needs to be replaced.
Absecon Bay – In this area we have four platforms to replace. Three will be moved and one new one installed. Four other nests need critical repairs.
Sea Isle – several nests here need predator guards and a couple need minor repairs.
Wildwood/Cape May – After the strong storms in late June hit this area, many nests need new platform (tops) and others need to be cleaned off.
If you are interested in being notified when these platform construction and repairs occur, please email me. Let me know what you are interested in helping with and if you have a boat (and a ladder!) that can be used.
Boaters urged to not approach active osprey nest inside Barnegat Inlet

Osprey Nest #3591
Yesterday, while working on Barnegat Bay, we visited this natural nest that is behind the dyke inside Barnegat Lighthouse State Park. This is the third time we’ve passed by to monitor their success. So far, so good and it looks like they now have young in the nest. As you can see the nest is built in a precarious location on a sandbar. When the sandbar is exposed people can walk right up to the nest. Last year the pair did not raise young but people did still walk up to the nest. With young, the adults will be more defensive of their nest to protect their young.

This past Saturday we “unveiled” the new Nature Trail at the Long Beach Island Foundation of the Arts & Sciences (LBIF). At the event we also conducted our first native plant sale, with lots of wildlife friendly plants, including milkweed, goldenrod, joe pye weed, bayberry, red cedar and many others. I lead guided tours along the trail to point out key features and work that we’ve done at LBIF. Our first stop was to the roof top of the Science Building, which is one of my favorite views. It provided visitors an opportunity to see what is the core foundation for our work, Barnegat Bay and some of the wildlife that we work tirelessly to protect and monitor: ospreys and northern diamondback terrapins, in particular.
92 Ospreys Enlisted in Citizen Science Based Re-sighting Project

This is the critical time of year for monitoring our nesting ospreys. Each year biologists and specially trained volunteers, aka Osprey Banders, conduct ground surveys by boat to monitor the state population. They visit or survey the most densely populated colonies of nesting ospreys: Sandy Hook, Barnegat Bay, Great Bay, Absecon, Ventnor-Margate-Ocean City, Great Egg Harbor Watershed, Sea Isle, Avalon-Stone Harbor, Wildwood, Maurice River, and parts of the Delaware Bay. These surveys have been conducted since the early 1970s when ospreys were not so common, with only 50 pairs in 1973.
Their recovery has been quite remarkable. With an estimated 600 nesting pairs throughout the state, our ospreys are in a much better position today. Why put so much time and effort into monitoring a seemingly healthy population? Even though their population is much larger than it was decades ago, ospreys still face a variety of threats that jeopardize their ultimate survival. It’s commonly known that ospreys face very high mortality rates in their first year of life. Before even leaving the nest their young are so vulnerable. They can fall or be blown out of the nest, predated by raccoons, crows, or eagles, killed by their own siblings, or die from starvation. After they fledge, then they need to learn to find and catch prey and avoid power lines and wind turbines. Then they need to learn to migrate south and avoid being shot in the process. Once they find a suitable wintering site, then they remain in the same area for the next two years. Then they return to their natal areas to find a suitable nest site and start their own osprey family!
Today, we need your help! We cannot reach all active nests in New Jersey. There is still plenty of time to help us keep track of the state population. Citizens are encouraged to submit sightings of activity at osprey nests on Osprey Watch, a global osprey watching community. In 2013 all of the known locations for osprey nests was released on Osprey Watch’s website. As a partner with Osprey Watch, we share and use the data collected to help determine the overall health of the population, which is summarized in our annual report.
To help engage our Osprey Watchers, we started Project RedBand, a citizen science based osprey re-sighting project. This is year two of the project. So far we’ve deployed 92 red bands (out of 100) on young produced at nests on Barnegat Bay (62 in 2014 and 30 in 2015). The young that were banded last year will start to return to New Jersey in 2016. Usually young adults return later than older adults, so the red banded birds might not be seen until May or June. That’s when they’ll find areas with high prey availability and suitable nest sites. Usually males don’t stray far from their natal areas but females do. With these red bands, we hope to learn a little more about where our ospreys are dispersing to and at the same time engaging our coastal communities in osprey conservation.
