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.
Preservation of declining habitat is key to survival of high marsh wildlife

As the sea rises, high areas on the coastal salt marsh will decline or disappear. These areas are higher in elevation and usually consist of more sandy soil. The sandy soil attracts nesting female diamondback terrapins, like many roadsides throughout New Jersey. As we harden shorelines to hold back floodwaters, terrapins will face more dangerous treks to find suitable nesting habitat, unless these high marsh areas are enhanced and elevations raised. For the past five years we have been surveying Route 30 (Whitehorse Pike) during summer months for the occurance of terrapins on the highway. Adult female terrapins enter the roadway while seeking these sandy areas above the high tide line. Most, if not all, do not survive crossing Route 30.

As a Principal Zoologist for the New Jersey Department of Environmental Protection’s Endangered and Nongame Species Program, 2017 Women & Wildlife Inspiration Award Honoree Kris Schantz works with one of New Jersey’s most underappreciated and persecuted species: the timber rattlesnake. She earned her Masters of Science degree from Rutgers University based on a study of the rattlesnake and its habitat in northern New Jersey, and her passion in both learning and developing greater understanding of this species has helped improve its protection.
Ms. Schantz partners with academic and consultant biologists, as well as a number of reptile enthusiasts to accomplish the New Jersey Department of Environmental Protection’s conservation mission. Her responsibilities have expanded to include other vulnerable snake species, such as the corn snake, northern pine snake, and scarlet snake.

While removing our seasonal (better late than never!) terrapin X-ING signs on Great Bay Blvd. in Little Egg Harbor yesterday, we stumbled upon some tiny northern diamondback terrapin hatchlings. These little guys were hiding or trapped under a very large (and heavy) X-ING sign made from old pallets that someone knocked over (I say guys because they hatched later in the season and it was a very cool August, but some could be girls). At first I didn’t see anything, but upon closer inspection I saw several hatchlings in the vegetation. One, two, three, four, five, six. Then I dug a little with my hand and found two more. The sign had been atop a nest. Continue reading “Photo from the Field”
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.
Anyone who has monitored or closely followed piping plovers knows these (pictured) tracks well. They have to. Most wildlife leaves behind distinct clues that reveal their presence, but if you are tracking the well camouflaged piping plover, the best, and sometimes only, clue you have are these ephemeral tracks in the sand.
Finding these tracks, especially the first ones of the breeding season in early spring, makes my heart stir, even after 20+ years of searching for piping plovers. They shout, “I’m here, now find me”. These particular tracks happen to be a late season find, sighted just this past week, special in a different way as they were unexpected and may be my last glimpse of them here in New Jersey this year as most piping plovers have now migrated south for the winter. I followed the tracks like I always do and soon enough I spotted three pale beauties resting absolutely still on a nearby sand hummock.
This blog doesn’t contain any earth-shattering conservation message. It is just about my own love affair with piping plovers. I am lucky to have found that magical something in nature that moves me. I hope each of you has your own version, whether it be a delicate monarch butterfly improbably fluttering thousands of miles in the wind towards its wintering grounds in Mexico or a powerful bison lumbering across a grasslands vista out west. One of the main reasons my colleagues and I are engaged in conservation work is so everyone has the opportunity to experience and be inspired by wildlife in its natural habitats.
Piping plovers will not provide a cure for cancer, they will not boost our economy, and they certainly will not be the key to uniting us politically. They will bring a smile to your face, they will evoke wonder, and they may just make your day. Sometimes that is enough.
