Egg 1 was laid on February 14th this year. Bald Eagle eggs are incubated for about 35 days. That means the first hatch could be next week, Wednesday, March 21st! What are the signs hatching has begun? As an observer for many years, viewing the live cam has taught me much. These are some behaviors I’ve seen in the past to alert me that hatching will soon begin or is already underway.
Believe it or not, the adult and chick can “talk” to each other through the shell. Watch for the adults to stand over the eggs with their heads bent closer to them. You may even see movement of the adult’s bill, as it “chirps” to its chick inside the egg.
If food begins to show up in the nest, the adults could be preparing for another mouth to feed. They are stocking the “pantry”.
Restless adults, with lots of moving around on the nest, or more frequent egg rolls, is another sign to watch carefully. When you get a clear view of the eggs, look for a tiny hole or a spider web-like cracking. This first hole in the shell is called a pip, and is made by the chick. The chicks do all the work!
Pips can be difficult to spot with protective adults blocking the view. You may wonder if you are looking at a spot of dirt or piece of grass on the egg or a real pip. Trust your eyes and keep watching, that pip will increase in size. This is exhausting and hard work for a little one. The complete hatching process can sometimes takes a day or two.
It is amazing to watch the progress once the first pip has appeared. Get ready for the most eggciting time of year for eagle watchers!
We are honored to have Diane Cook as a guest blogger, over the next few months. Diane will be discussing Duke Farms eagle cam and how she uses it in her classroom. Diane is a K-2 Technology Literacy teacher at both Copper Hill and Robert Hunter Elementary schools. She has been an avid and enthusiastic eagle cam viewer since 2008 and now she is the official nest monitor for the Duke Farms nest. As the monitor Diane records important data into the Eagle Project database, Nest Story. Diane also uses the eagle cam in her classroom and was the winner of a contest held by Duke Farms and CWF in 2015, to choose the best bald eagle lesson plan.
Diane was home from school during yesterday’s snowstorm and able to document the eagles during the storm.

Thankfully the live cam was back up and running by the time school started on Monday following the first Nor’easter to hit our part of NJ. Was glad to be able to tell the students all was well, and that they could see for themselves! The good news was soon replaced by worry with yet another Nor’easter predicted for today. The day began slowly. Yes, it was snowing, but lightly. Things didn’t look too bad.
Within minutes, the snow really picked up in intensity. The storm hit quickly and the snow fell fast and heavy. Within minutes snow had covered the ground.
There was an exchange at some point on the nest. Mom won the rights to incubation. Then something I’ve never seen before happened. BOTH eagles stayed on the nest through the storm. They laid side by side.
Thanks to Charles T. Barreca who mans the camera at Duke Farms for the awesome close up view. As the camera moved, the eagles looked up at the noise.
They would shake off the snow, but remained on the nest together.
More snow fell. Still the eagles sat.
Finally the male flew off the nest, but stayed on a nearby branch.
No matter how much snow fell, these dedicated parents remain with their eggs and incubation continues.
On a cool and cloudy Monday morning, CWF Habitat Program Manager, Ben Wurst was joined by News 12 New Jersey reporter, Tony Caputo to highlight the osprey’s triumphant recovery in the Garden State. Ben was working in the field to repair a few osprey nests and complete the first of several nest checks at a nearby peregrine falcon nest. We work tirelessly to ensure that when ospreys return from their wintering areas that their nesting platform are in good condition.
We were subcontracted by NJDOT to install a new nesting tower for peregrine falcons in Stafford Twp., Ocean County. We’ve assisted NJ Fish & Wildlife with monitoring the falcon nest that was previously located beneath the Route 72 Causeway Bridge for the past several years. The new tower is located on Bonnet Island and highly visible on the eastbound side of Route 72. Continue reading “Photos From the Field: Bonnet Island Falcon Tower”
The WNET-PBS Nature program Peril & Promise celebrated the Great Backyard Bird Count with two live interviews with Conserve Wildlife Foundation at DeKorte Park in the Meadowlands.
In the first live interview, CWF Executive Director David Wheeler and Jim Wright, who has written widely about birds and the Meadowlands, discussed the importance of bird counts to CWF’s work, and the growing threat of climate change on bird populations around the world.
Climate change is “toughest on the migrants,” said Wheeler. “When you think about a bird leaving its neotropical wintering grounds in Central or South America and then coming up to New York or New Jersey, that’s a leap of faith that everything is as it has always been. But in reality, as spring seems to arrive earlier each year along with the leaves, the foliage, the insects, basically the bird risks coming back to a depleted prey resource – and they can struggle to survive.”
Richard W. DeKorte Park is a nationally recognized birding hotspot along the Atlantic Flyway with 3.5 miles of walking trails in the shadow of the Manhattan skyline, part of the Meadowlands region where over 285 bird species have been identified. It is managed by the New Jersey Sports and Exposition Authority.
CWF’s bald eagle project was featured in a news feature today on New Jersey 101.5 FM.

January kicks off bald eagle nesting season in the Garden State, and biologists from CWF and the Endangered and Nongame Species Program are working with volunteers across the state to monitor the nests of approximately 150 bald eagle pairs – up from 1 nesting pair just a few decades ago!
Statewide Census Documents over 650 nesting pairs in New Jersey

An osprey prepares to land on a natural nest. Barnegat Bay, NJ.
Since we began to work more closely with ospreys in 2006, we have documented the population grow beyond the historic population estimate of 350-450 nesting pairs (Henny 1977) to a new historic milestone. In 2017, a total of 668 active nests were recorded during a statewide census of nesting ospreys, which is well above the post-DDT milestone of 500 nesting pairs, and show that the population continues to grow. This is the second census conducted without the use of manned aircraft since 2009 after all known osprey nests were released and mapped online in 2013. Despite the lack of aircraft, we’re still able to obtain an accurate representation of the size and health of the statewide population, while reducing the overall project cost.

CWF will be at the festival on February 3rd. There are presentations, walks, viewing sites and exhibitors. It’s a great way to learn about NJ’s eagles and other raptors.

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.
