In January 43 states participated in the Midwinter Bald Eagle Count including New Jersey which has participated since 1979. This year in NJ ~70 volunteers surveyed for eagles the weekend of January 14th & 15th. The purpose of the survey is to monitor bald eagle populations. Since the survey takes place at the start of the NJ eagle nesting season possible new pairs and nests are often found. New Jersey volunteers also map eagle activity and these data are used to delineate critical eagle wintering habitat.
This is a great time of year to get out and see some eagles. Not only are the resident nesting eagle pairs around but also wintering eagles.

Bald eagles are beautiful birds so it only makes sense that people want to get a closer look at them. But often people don’t realize that by innocently stopping to look at an eagle nest they are putting the eggs or young in jeopardy. As the New Jersey eagle population increases eagles are starting to nest in closer proximity to humans and human activity. Any activity that causes the eagles to change their normal behavior is “disturbance.” People walking too close to the nest to get a closer look or take photos will cause the birds to get off the eggs or leave the young unattended. This leaves the eggs or young exposed to the elements and predators. The safe distance for viewing is at least 1,000’ from the nest site. If the birds are looking at you then you are too close.
The best way to see what goes on at an eagle’s nest without the chance of disturbing the birds is to watch them online. The Duke Farms eagle nest site has had a camera streaming the picture since 2008. This provides an up close and personal view that you cannot see from the ground. The Duke Farms eagle cam should be streaming live in the next few weeks. To view the eagle cam go to www.conservewildlifenj.org
If you have any questions about eagles or their nests or would like to report a nesting pair, please contact Larissa Smith.

“Where do the chicks go when they leave the nest?” is a question that I get asked pretty often. The Conserve Wildlife Foundation of NJ , Merrill Creek Reservoir, and the Endangered and Nongame Species Program collaborated on a new project that will help to answer this question. On June 13, 2011, biologists visited the Merrill Creek Reservoir eagle nest located in Warren County. The chicks, one male and one female, were each fitted with a transmitter attached by a harness made of Teflon ribbon. The solar-powered transmitters, monitored via satellites, allow the birds to be tracked for up to three years as they move away from the nest, migrate south, and move around the region before they begin to establish their own territories. Following the birds movements will help us to identify what type of habitat they are using during their first years.
The eaglets fledged around July 11th and both stayed in the area of the reservoir into mid- September. On September 14th the female eagle headed East to Long Island, NY. She spent time on the eastern most tip of the Island and started heading back to Merrill Creek Reservoir on September 28th. On October 17, the female was found on the ground at the reservoir in a lethargic condition. She was taken to the Raptor Trust in Morris county, but she died the following day. She tested positive for West Nile Virus.
The male eagle headed the opposite direction into PA and on September 19th was just west of the Susquehanna River near Harrisburg, PA. He headed back east and spent time in Bucks county PA before heading back to NJ. As of November 15th the male was in Warren County near the Musconetcong River.

2011 was a great year for bald eagles in NJ. This season a record high of 118 chicks fledged from nests throughout New Jersey. A total of 111 eagle pairs were monitored of these 95 were active which means that they laid eggs. Seventy-one of these were successful in producing the 118 fledges. This is especially good news after 2010’s less than stellar nesting season where only 69 young chicks fledged.
The success of the NJ Bald Eagle Project is directly due to the dedicated volunteers. Every eagle nest that can be viewed is monitored by a volunteer/s. Volunteers report on important dates such as incubation, hatching and fledging. They also help to protect the nest by reporting disturbance and educating the public about eagles. We can’t thank our eagle project volunteers enough for all the time and energy which they put into this project.
More details on the the 2011 nesting season will be available later this year in the 2011 NJ Bald Eagle Project report.

Each spring Calling Amphibian Monitoring Project (CAMP) volunteers take time out of their busy lives to drive the dark roads of NJ and listen for the calls of NJ’s amphibians. Not only do these volunteers have to find the time to schedule the three surveys, each in a specific four week period, they need to meet the protocol for the surveys. This means meeting the minimum temperature requirement, which is not the easiest in March, as well as other weather protocol. Once they find a perfect night to survey the volunteers follow a 15-mile route with 10 stops. They stop and listen for 5 minutes at each stop and record the amphibians they hear. This can be a frustrating experience depending upon the route. Noise from cars can make surveying difficult and some of the routes in more developed areas record no amphibians calling on many of the stops. Meanwhile volunteers on the less developed routes can often hear a chorus of frogs and toads that can be almost deafening.
I’d like to thank all the dedicated CAMP volunteers for finding the time to survey this season.
Thirty-one volunteers surveyed 33 routes. Each route is to be surveyed three times during the spring in March, April & June. A total of 77 surveys were conducted. All 16 species of NJ frogs and toads were detected on the surveys. The species that was heard on the most routes was the Northern Spring Peeper which was heard on 31 routes out of 33 that were surveyed. The second most detected species was the Green Frog heard on 22 routes out of the 33 surveyed. The least detected species was the Spade Foot Toad which was only heard on one route.

On Friday May 13th the eagle banding team met to visit two eagle nests in Cumberland County. The first nest visit went smoothly, two healthy chicks were banded, blood samples and measurements were taken. The second nest was located on an island out in the salt marsh. As we approached the island we could see that the nest looked somewhat small and it looked like some nesting material had fallen out of the tree. As we got closer to the nest tree both of the adult eagles appeared and were making their alarm calls (which is normal) when we go out to band an active nest. As Mick Valent, Principal Zoologist with the Endangered and Nongame Species Program, prepared to climb the tree we started to look for prey items which we collect at each nest. One of the eagle project volunteers made a sad discovery, the remains of a 4-5 week old eagle chick. We then knew that something had happened to the nest. As Mick got closer to the nest he told us that there wasn’t a nest and it must have fallen. But the adults behavior indicated that there was still a live chick. We thought perhaps that the second chick was still alive on the ground, so we started to search. Mick made his way up to the nest remains and we heard him yell, “there is a chick”. It was decided that the chick would be brought to the ground banded and examined. The nest would then be rebuild so that the chick could be put back up into the nest.
Erica Miller a veterinarian from Tri-State Bird Rescue and Research examined the bird. It had a full crop which means that it was being fed. The only indication of its trial was a sore on the bottom of its foot pad from holding on tight to the remaining nest.
Meanwhile Mick began constructing a new nest base with large branches that were sent up using rope. Jeremy Webber with the NJ Forest Service is training to climb nest trees and was able to assist in the nest building. Once a base platform was constructed the remaining nesting material was put up on the platform and then tied down so that it wouldn’t slide off the platform. Softer material was sent up in a bag for the final touches. The chick was then sent back up and placed in his new home.
We estimate that the nest had fallen in the past two weeks. The chick wouldn’t have been able to hang on much longer especially with any high winds or rain storms. The nest volunteers went out the next day and reported that the chick was fine and the adults were at the nest. It may have been Friday the 13th but it was this chicks lucky day!

On Sunday May 1st Liz Silvernail, CWF Director of Development, and I spent the day at the Atlantic County Utilities Authority Earth Day celebration. The weather was gorgeous and we were busy all day talking to people about CWF and the different projects that we are working on. Kids especially stopped by to see the mounted Barred Owl, Peregrine Falcon and turtle shells. Also helping at the table were volunteers Matt Klewin, Margaret Klewin-Atack and their daughter Rhianna. Their team the, Wrending Talons, which has been together for 18 years, will be participating in the World Series of Birding on May 14th and CWF is the recipient of their pledges.
We also had a free raffle for an eagle bird house made by eagle project volunteer Kevin Buynie. The winners were Tari Clark
and her daughter Rebecca. They were thrilled to be the winners and were excited to see if any birds would nest in the house this year.

If you haven’t yet seen the Duke Farms Eagle Cam please check it out. It’s a great opportunity to
see what goes on at an eagles nest and it can be addicting! The Duke Farms eagle pair has been nesting on Duke Farms property since 2005 and have raised and fledged eleven chicks. Both the adults in the pair are NJ banded birds which we know by their green leg bands.
This season there are two chicks. The first chick hatched on April 7th and the second hatched on April 9th. The adults will brood the chicks to keep them warm so right now a great time to see the chicks is during feeding sessions. Both chicks are getting plenty of food!
It’s hard to believe that these tiny chicks will be full grown and flying in about twelve weeks! To read updates on the chicks and their development go to:

This week I had the opportunity to speak to a group of 5th grade students at the Ocean City Intermediate School. The group of 44 students are in Mrs. Rosander’s science class. Over the holidays the students earned money for a charity and this year they chose to adopt a piping plover for their classroom through the CWF Adopt a species program.
As part of the adoption they received a classroom visit by a CWF staff person, which was me. I spoke about NJ’s rare wildlife and of course their adopted species the Piping Plover. The students were already very knowledgeable about NJ Endangered and Threatened species. One of their class assignments was to write an essay or draw a picture of one of NJ’s E & T species. For extra credit they could do both and those were entered in the Species on the Edge Art & Essay contest. The students had a lot of great questions for me and I think there are some future environmentalists in the group!
