PLASTICS MAY THREATEN WILDLIFE FOR MANY YEARS

by Corrine Henn, Communication Coordinator

For those of us who call New Jersey home, we’ve all likely witnessed the impact human activities have on our environment and the species who thrive here. Although habitat loss, illegal poaching and invasive species can be equally devastating to an ecosystem, the presence of plastic pollution around our state is a threat that almost every individual can be found personally culpable.

Although many forms of pollution impact our native species, the summer months at the Jersey Shore often result in a surge of plastic debris that are left behind or improperly disposed of. Plastic pollution impacts millions of wildlife species globally, and the diverse number of species in New Jersey are no exception.

The plastic pollution that accumulates in our waterways and elsewhere around New Jersey poses a serious threat to native species. Single-use plastic products like plastic bags, bottles, bottle caps, wrappers, straws, and even balloons are not only unsustainable, but particularly dangerous for the animals that may become entangled in them or accidentally ingest them.

A few years ago, CWF’s Habitat Program Manager Ben Wurst and his dedicated group of volunteers who monitor the osprey nests along the coast began to hold onto the trash and debris collected in and around the nests. While it may not be the most visually appealing educational resource, it made the growing problem of plastic pollution personal for Ben, in a way that words aren’t always able to convey.

Plastic bags, one of the most common single-use plastic products, were overwhelmingly prevalent in many of the nests. And osprey aren’t the only wildlife species facing this threat. Seals, terrapins, shorebirds, fish, whales, sharks and dolphins can also be impacted by plastic debris.

The presence of plastic in our daily lives is interminable and difficult to eliminate completely, but there are a number of things we can do to minimize the impact our habits may have on our wildlife!

Clean up after yourself:
Whether you’re spending the day at the beach, having a picnic by a lake, or tubing down a river, make sure you take any trash with you before leaving and recycle what you can.

Be mindful of your surroundings:
If you’re out and about and notice that someone left some trash behind, take a moment to throw it away.

Reduce your consumption:
A number of small changes from millions of people can make a big difference. For starters, invest in reusable shopping bags and water bottles. And cut down on the number of miscellaneous throw away plastics you use, including straws and plastic wrappers.

Donate:
Consider donating to CWF to support our conservation projects and ensure our biologists and our volunteers are able to continue surveying and aiding species in need.

Project RedBand alumni update 

by Ben Wurst, Habitat Program Manager

Ospreys are in the news again. This time it is not so pleasant news, or at least news that is hard to swallow for some, where an adult bald eagle predated a young osprey at Hog Island in Bremen, Maine. While it can be a traumatic thing to witness firsthand, it is pretty common where the range of ospreys and bald eagles overlap. We are only witnessing it because of technology. It can and has happened right here in New Jersey too. Last year, I found an adult female who had lost her wing. With no other way for that to happen (on the open saltmarsh, and her wing was gone), the only suspect is an attack by a bald eagle. As both the eagle and osprey population continue to grow, there will only be more interaction between the two species as they are competitors for food and bald eagles are opportunistic scavengers.

In other more local osprey news, on the afternoon of July 25th I got the most unfortunate news. Osprey 39/D was found dead near the nest where he fledged just two weeks ago. If you are not familiar with this bird, it is one who has graced the pages of the Asbury Park Press, The Sandpaper, and many other news networks online. His daring rescue was viewed over 2,800 times.

Filling in the gaps

by Ben Wurst, Habitat Program Manager

Each year, while conducting osprey surveys by boat, our volunteer banders and biologists try to reach the majority of known osprey nests in the most densely populated colonies in New Jersey. The data that is collected (active nest, # of young) help to determine the overall health of the population. Since 2013, we have surveyed more than we have ever have, after releasing all of the known locations of osprey nests in New Jersey. All osprey nests can be viewed on our partners website, www.osprey-watch.org, which is run by the Center for Conservation Biology. It has helped us reach 80% of the known population. Publishing and mapping all the known nests was an attempt to engage citizen scientists (by them going out to observe ospreys) and save critical funding (for more endangered species of wildlife) while collecting data to monitor and manage our ospreys. So far it has proved to be an amazing tool for the future management of ospreys, who nest in very close proximity to humans. Continue reading “Calling all Osprey Watchers!”

A promising outcome from a dangerous situation

by Ben Wurst, Habitat Program Manager

Yesterday evening, while conducting an osprey nest survey at Sedge Island Wildlife Management Area, I received a message from a local wildlife photographer about an osprey nestling that was entangled. I talked to the photographer, Rich Nicol and got detailed information about the situation, the nest, and started to formulate a plan to address the situation. After learning that the nest was on a 35-40’ high pole, I knew that I wouldn’t be able to get up there without some help. Yes – a large ladder would suffice, but it would be tricky to handle the situation (with the bird being entangled). You see, after seeing photos of the young osprey, I knew it was RTF (Ready To Fly). Ospreys fledge or take their first flight at around 7-8 weeks of age. The entangled osprey was around 7 weeks old. I knew we had to act quickly to catch the bird and untangle it before it tried to fledge. This morning I saw the photos that Rich took and it clearly showed that the young osprey had monofilament or a net around its neck… Continue reading “The Inspiring Story of Osprey 39/D”

Osprey 44/C re-sighted at Island Beach State Park!

by Ben Wurst, Habitat Program Manager

Really exciting news. For the first time this year, a (live and well) red banded osprey was re-sighted! 44/C was banded as a nestling on July 12, 2014 and photographed by Shayna Marchese on July 3, 2016 at Island Beach State Park. Young ospreys spend two years on their wintering grounds before returning to their natal areas. This is the first year that 44/C has returned to New Jersey. 44/C appears to be a male, and males have a higher level of site fidelity than females do, so they are more likely to return to the same area that they originated from. We aren’t surprised that one of our first red banded birds to be re-sighted in New Jersey was at Island Beach State Park, just outside Sedge Island Wildlife Management Area. For anyone who is not familiar with Sedge, it is the state’s most densely populated osprey colony in New Jersey. Around 30 pairs of ospreys nest at Sedge which is less than 3 square miles.

What you won’t hear on the news!!

by Ben Wurst, Habitat Program Manager

It’s osprey season. Osprey Survey Season, that is. However, we never like to start the season off with these types of emergency surveys, but with the increase of strong storms and extreme straight line wind events, they are becoming an annual event. Ospreys nest on platforms in open areas near water, so their young can easily become victims during these types of storms. After receiving a text message from my colleague Kathy Clark yesterday evening about the intensity of the storms, she said we should try to do a survey of the affected areas. I had other plans but I knew that those could wait. Continue reading “Emergency Osprey Nest Surveys in Cape May, Wildwood and Stone Harbor”

CWF Releases its Second Annual Report Using a Story Map Format:

“2015 Annual Report“

Technology has proven to be vital to Conserve Wildlife Foundation’s work protecting rare wildlife species over the years. Our biologists depend greatly on modern technologies to band, track, and share online the journeys of wildlife. Our webcams broadcast the most intimate behaviors of nesting birds and bats across the web. And we seek out ever-evolving communications technologies to spread the word about the inspiring stories of wildlife, from social media and infographs to e-books and Story Maps. These technologies offer newfound abilities to share complex data on multiple levels, while still incorporating the awe-inspiring photography and videos that bring wildlife’s stories to life.

Conserve Wildlife Foundation of New Jersey is excited to offer our 2015 Annual Report in a unique format that utilizes one of those technologies – Story Maps. In the past year, we have explored the lives of seals, eagles, and freshwater mussels with Story Maps – and the annual report allows all of our projects to be highlighted in this interactive format as well.

Visit the multiple pages within this Story Map to learn about Conserve Wildlife Foundation’s many projects and partnerships in 2015, and the imperiled wildlife species in need of our help. Find examples of the innovative and dedicated leadership of our biologists and volunteers. And take an online journey across the state to learn how our projects made a difference in all corners of New Jersey in 2015 – a great year for wildlife in the Garden State!

New document provides guidance to homeowners and landowners with osprey nest issues and focuses on the use of UAVs around active nests

by Ben Wurst, Habitat Program Manager

In New Jersey, we’ve seen the osprey population grow to an estimated 600 nesting pairs in 2015. As the population continues to grow, work to identify, protect, and remedy problem nests is crucial for their long term survival. Each year many new young adults return to their natal areas to find suitable areas to construct nests. Ospreys have a high level of site fidelity and usually return to the same areas where they originated (females do tend to wander more). A suitable nest site for an osprey is a high structure near water, usually away from human disturbance. However, ospreys can become more tolerant of disturbance if it can be expected and is not too close to their nest, especially for those birds that nest on tall structures.

Ospreys build large nests which can weight up to 200 lbs. They use sticks, grass, muck, seaweed, eelgrass, reeds, and often trash to build up their nests.

Around 75% of the state population nests on man-made platforms that are designed specifically for them. The other 25% is a mixture of nests built on other man-made structures and a few natural nests. Yes, ospreys do still nest in trees! But, trees that are suitable for them are few and far between. A suitable tree for an osprey is a standing dead tree (snag) or a tree with a top that has broken off. As the population continues to grow and there are fewer nest sites available on platforms and few suitable trees, more nests are being built on man-made structures where problems can arise. Ospreys are being pushed to nest in areas that are not always ideal, like on utility poles, stadium lights, emergency sirens, communication towers, boat lifts, docks, and even houses. Nests on utility poles can cause power outages and sometimes the nest might catch on fire or an adult can be electrocuted. Nests on houses, docks and boat lifts often limit use of such structures unless dealt with properly, but active nests cannot be removed without consulting with experts. 

In partnership with NJ Division of Fish and Wildlife’s Endangered and Nongame Species Program, we developed a new guidance document to help address problem nests. “Living with Ospreys in New Jersey: A guide for the removal, relocation, and placement of osprey nests” addresses the laws protecting ospreys, who are protected both federally under the Migratory Bird Treaty Act of 1918 and statewide under the Endangered Species Conservation Act of 1973. Both of these laws protect the nest, adults and the contents of the nest, eggs and young. It also gives guidance on what actions can be taken to access, remove, or relocate an active or inactive osprey nest on any man-made structure, including communication towers. Also included are directions on how to build and install an osprey nesting platform.

Lastly, it also provides some clear guidance on the use of UAVs near active osprey nests. UAV pilots must follow all FAA guidelines and not fly within 1,000 feet of any active osprey nest. To an osprey, a UAV looks like a potential predator. Ospreys will defend their nests and attack any potential predator at nest sites. Simply flying near a nest can add stress to birds and cause adults to fly off nests where their young are vulnerable to predation. Any pilot who flies within this area and pursues or harms an osprey or its young is in direct violation of the Migratory Bird Treaty Act. We ask that all UAV pilots use caution to protect the safety of our ospreys and other birds.

Enhancing public access to Barnegat Bay and its inhabitants!

by Ben Wurst, Habitat Program Manager

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.
