Another Dead Humpback Whale Was Found Floating Off the Jersey Shore

Thursday, November 19th, 2020

On Thursday, November 5, 2020, a 20-25 foot juvenile humpback whale (Megaptera novaeangliae) was found dead floating near a sandbar in Townsends Inlet in Cape May County, New Jersey. The large mammal had apparently been dead for several days. It was first spotted around 3:30 p.m. Wednesday. 

This tragic event follows even more heartbreaking news about Right Whales, the most endangered large whale species in the world! 

The North Atlantic Right Whale.

We are very sad by the announcement by researchers at the North Atlantic Right Whale Consortium that the estimated number of North Atlantic right whales (Eubalaena glacialis) remaining in the world is just 356, not 400 as previously thought. It is truly upsetting news. The population continues to be in decline, and the decline is accelerating. 


ABC Action News: Horseshoe crabs play key role in race for COVID-19 vaccine

Saturday, October 3rd, 2020

by Walter Perez

Horseshoe crab blood is hypersensitive to dangerous bacteria that can develop in injectable medicines and vaccines.

In the race for a vaccine for COVID-19, horseshoe crabs – a New Jersey coastal fixture both now and eons ago in the days before the dinosaurs – may play a vital role.

This video story by ABC Action News features CWF Executive Director David Wheeler and top shorebird scientist Dr. Larry Niles in telling this science fiction-like tale.

Public Participation Key to Protect Terrapins on Roads

Wednesday, June 12th, 2019

Local residents and visitors in coastal areas urged to drive carefully during summer months.

by Ben Wurst, Habitat Program Manager

To cross or not to cross? Roads are barriers to wildlife, like this adult female northern diamondback terrapin.

This year marks nine years since we began efforts to document and reduce roadkills of N. diamondback terrapins in S. Ocean and N. Atlantic Counties within the Barnegat and Great Bay Watersheds. Our Great Bay Terrapin Project was centered around Great Bay Blvd. or Seven Bridges Road, a long saltmarsh access road where many adult female terrapins enter the roadway while seeking nest sites.

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, ospreys have 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.

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

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.
