Human Interaction and Quick Action Ensure Survival of Young Falcons in Urban Areas
by Ben Wurst, Habitat Program Manager
Yesterday NJ Fish & Wildlife Zoologist Kathy Clark and I visited 101 Hudson St. after watching the Jersey City Falcon Cam for several days since the first and only egg hatched on Wednesday evening, we became more and more concerned for the health of the 5 day old eyas. We also came upon a brood of three young (and healthy) falcons who were displaced (we’ve called them orphans) from the old Goethals Bridge, which is currently being deconstructed. Knowing that the orphans needed a home, we decided to visit JC and assess the health of the lone eyas, collect the unhatched eggs, and possibly foster in the orphans here.

SEVERAL SPECIES OF FRESHWATER FISH TO RECEIVE IMPERILED STATUS
By Michael Davenport, GIS Program Manager
The New Jersey Division of Fish and Wildlife has recently completed a status review of the freshwater fish species within the state. A total of 53 species were reviewed by a panel of experts and the results of that review were then presented to the Endangered and Nongame Advisory Committee which voted on March 16th to recommend the status changes. As a result of this status review, ten additional species within the state will be receiving an imperiled status of either Endangered, Threatened, or Special Concern. The date for when those listings will become official is still unknown.
Conserve Wildlife Foundation of NJ’s online field guide, a one-of-a-kind free reference focused on New Jersey’s wildlife, has expanded to include the additional fish species.

HOW A SPECIES BECOMES LISTED AS “ENDANGERED” IN NEW JERSEY
By Michael Davenport, GIS Program Manager
How does the state’s Endangered and Nongame Species Program (ENSP) determine whether a species is imperiled or secure within the state? The process for determining a species’ state status is known as the “Delphi” method of species status review and it is a process which Conserve Wildlife Foundation of NJ (CWF) staff assists the state with.
In 2015, the NJ Endangered & Nongame Advisory Committee approved that the monarch butterfly be added to the state’s list of Special Concern species. Photo courtesy of Thomas Gorman.
The ENSP endeavors to complete a review of all species currently included on the Endangered and Nongame lists every 5-10 years. In addition, other species groups not currently included on those lists may be reviewed for status as well. At any given time, there may be several status reviews being conducted.
The first step taken in conducting a status review is to identify experts and invite them to participate as a member of a review panel. Members of the panel may be comprised of experts within academia, government agencies, non-profits, or private consultants as well as others.
Once a sufficient number of experts have agreed to participate, staff within the ENSP and CWF will compile background material for the species being reviewed. This may include reports, survey data, and data contained within the state’s Biotics database which is the electronic warehouse for all imperiled species data in New Jersey. This background data, as well as a list of the species being reviewed, and definitions of the status options, are then sent to the panelists for Round 1 of the review.
Delphi reviews are comprised of multiple “Rounds”. For each round, each panelist will choose a status for each species based upon that panelist’s expertise as well as the background material. The panelist then sends their selections and justification regarding each species to ENSP or CWF staff who compile the results submitted by all panelists. The review is completed anonymously, so the panelists do not know the identities of the other participants.
For each species, the panel must reach consensus of at least 85% of the respondents for a species’ status to be determined. If consensus is not reached during the first round, then that species will move on to be reviewed in Round 2. For each new round, the panelists’ status choices during the prior round, as well as all the comments made, are available to the panel, so that reviewers can consider the weight of evidence and other reviewers’ opinions on status as they prepare to vote again. This continues until consensus is reached for all species under review.
Once consensus is reached for all species or, if after four rounds have passed and consensus could not be reached for some species, ENSP or CWF staff will take the compiled Delphi results to the Endangered and Nongame Species Advisory Committee (ENSAC). ENSAC reviews the results and makes the final recommendations on status for those species for which consensus was not reached by the expert panel. Based upon ENSAC’s recommendations, any changes to the Endangered and Nongame lists must go through a formal rule-making process before those changes can be made official.
The Delphi review process is a science-based, anonymous review by those with the most expertise on the species within New Jersey. A great deal of thought and time go into preparing for and carrying out a review and CWF has played a major role in assisting with the process. From the blue whale to fairy shrimp, each species will ultimately receive a state status, leading the way for conservation action.
The following are state conservation status categories; the last, “Not Applicable”, is used only during the status review and is not a legal status category.
Endangered
Applies to species whose prospects for survival within the state are in immediate danger due to one or several factors, such as loss or degradation of habitat, overexploitation, predation, competition, disease or environmental pollution, etc. An Endangered species likely requires immediate action to avoid extinction within New Jersey.
Threatened
Applies to species that may become Endangered if conditions surrounding it begin to or continue to deteriorate. Thus, a Threatened species is one that is already vulnerable as a result of small population size, restricted range, narrow habitat affinities, significant population decline, etc.
Special Concern
Applies to species that warrant special attention because of inherent vulnerability to environmental deterioration or habitat modification that would result in their becoming Threatened. This category would also be applied to species that meet the forgoing criteria and for which there is little understanding of their current population status in the state.
Secure/Stable
Applies to species that appear to be secure in New Jersey and not in danger of falling into any of the preceding three categories in the near future.
Undetermined/Unknown
Applies to a species that cannot be assigned a status of endangered, threatened, special concern or secure/stable because not enough information exists on which to base a judgment.
Not Applicable
Applies to species that do not occur in New Jersey, including occasional non-breeding strays and transient breeders that fail to persist.
The U.S. Fish and Wildlife Service has reopened the public comment period on a proposal to list the northern long-eared bat as endangered under the Endangered Species Act (ESA). Comments will be accepted through Thursday, December 18, 2014.
The public is invited to submit comments one of two ways:
(2) By hard copy: Submit by U.S. mail or hand-delivery to: Public Comments Processing, Attn: FWS–R5–ES–2011–0024; Division of Policy and Directives Management; U.S. Fish and Wildlife Service, MS: BPHC; 5275 Leesburg Pike, Falls Church, VA 22041-3803.
The Northern Long Eared Bat, like many other bat species in the United States, is in danger of extinction due to White-Nose Syndrome, impacts to hibernacula, summer habitat loss and wind farm operation. Listing a species as endangered, under the protections of the Act, increases the priority of the species for funds, grants, and recovery opportunities.
Leave Dead and Dying Trees Standing: Where possible and not a safety hazard, leave dead or dying trees on your property. Northern long-eared bats and many other animals use these trees.
Install a Bat Box: Dead and dying trees are usually not left standing, so trees suitable for roosting may be in short supply and bat boxes can provide additional roost sites.
Last year 26 nesting pairs of peregrine falcons were monitored in New Jersey. The core of the state population nests on towers (old hacking towers) and on buildings in urban areas. Each spring we assist NJ Division of Fish & Wildlife’s Endangered and Nongame Species Program to help monitor the core of the population by performing nest checks and by installing a remote, motion-activated “spy” cam in nests to record the adults as they enter and exit nests. The footage captures the legs of peregrines. Why? Many peregrines are banded before they can fly with a federal USGS bird band and a state bi-color, alpha-numeric band. The state bi-color band can be read from the video captured by the camera. The information that these identifications provide is immensely valuable for relating peregrine origin and age to nest success, site fidelity and turnover rate in the population.
Here is a short clip from a nest site in Ocean Gate and the bird in the video was identified as a male (*8/*5, black/green) that was banded in 2005 at Sedge Island.
Roads are a necessary component to human survival. Since New Jersey is such a densely populated state we have a lot of them. Many of them have a negative effect on wildlife. One of these impacts is how they block or impede the natural migration of amphibians and reptiles as they search for mates or expand their territories.
During the summer I am always a little more aware while driving. In the next week many terrapins will begin to emerge from coastal waters to find nest sites. Box turtles and other freshwater turtles are seeking mates and nest sites. Snakes often bask in roadways to help them thermoregulate. Last week while I was driving down one road in the Pinelands I saw two cars pass me in the opposite lane. After they sped by, on the shoulder, I noticed something odd but I knew exactly what it was. A tail was flinging crazily in the air. I thought it was a snake but was’t 100% sure so I stopped and turned around to check it out. It turns out it was a snake and it was an endangered timber rattlesnake. This is only the second timber rattler that I’ve ever seen in the wild and they are quite a rare occurrence. It was still alive but severely injured. I pulled it off the road before another car hit it. I called Dave Golden a zoologist with NJ Fish & Wildlife and took the snake home with hopes that it would survive long enough to be transferred to the Cape May County Zoo. Unfortunately, it died an hour after I got home. As you travel our many roads this summer please be aware of your surroundings and watch out for any snakes or turtles that enter the roadway.
Timber rattlesnakes are a very docile snake, however they are still venomous and you can die if bitten. If you encounter a rattlesnake do not attempt to pick it up!!! I was extremely cautious of this snake even though it was injured. Please call 1-877-WARN-DEP immediately if you encounter a timber rattlesnake that is near your home and/or if you or it are in any kind of danger. Record information about your sighting and report it to the Endangered & Nongame Species Program here.

Our website features profiles on every one of New Jersey’s 73 Endangered or Threatened species in our Online Field Guide. Now, we’re beginning to profile New Jersey’s Species of Special Concern. The term “Species of Special Concern” applies to species that warrant special attention because of some evidence of decline, inherent vulnerability to environmental deterioration, or habitat modification that would result in their becoming a Threatened species. This category may also be applied to species that meet those criteria and for which there is little understanding of their current population status in the state. There are currently 108 species within New Jersey with the Special Concern status. So far, we have profiles for 18 of those species.
The 2010 New Jersey bald eagle nesting season has ended and the young eagles have left their nest areas and are heading out on their own. This season there was a high of 94 eagle pairs being monitored. Eighty-two of these pairs were active (laid eggs), 8 were territorial and it was unknown if and where 4 other pairs were nesting. Thirteen new pairs of eagles were located this season. Good news, the bald eagle population is increasing.
Forty-three nests were successful in producing 69 young, for a productivity rate of .84 young per active nest. This is slightly below the required range of 0.9-1.1 young per nest for population maintenance. Unfortunately there were 32 nests which failed to produce young this season. Many of the failures can be attributed to the severe winter and spring weather which coincided with the eagle nesting season. But every population has fluctuations so this one off season won’t effect the NJ eagle population in the long term.
More details will be available in the Annual Bald Eagle Project report which will be out by the end of the year.
