Banding and re-sighting birds is such a rewarding experience. You never know where and when a bird that you banded will show up and what you will learn from that encounter. Banding is a method for biologists to track migratory birds and gain valuable information about them through band re-sightings or encounters. Each year, around 10-20% of young ospreys that are documented during nest surveys in New Jersey are banded with USGS bird bands for future tracking. On Barnegat Bay, through Project RedBand, young ospreys are also banded with red auxiliary, or “field readable” bands. Since 2014, over 600 red bands have been deployed and in recent years we have had more re-sightings of birds that are alive as opposed to those that were found dead. In 2024, we identified 30 ospreys in New Jersey by their red bands.

The New Jersey Annual Bald Eagle Project report has been published by NJDEP Fish & Wildlife’s Endangered and Nongame Species Program and The Conserve Wildlife Foundation of NJ. The NJ bald eagle nesting population continues to increase. Two hundred ninety-three nest sites were monitored, of which, a record 264 were documented to be active (with eggs) and 29 were territorial or “housekeeping” pairs. In total, there were 288 fledglings resulting in a productivity rate of 1.2 young per active nest.
I never imagined the rewarding experience of observing adult ospreys that I banded as nestlings. Over the past decade, I have banded six hundred and twelve ospreys with field readable red auxiliary bands. These birds originated from nests throughout the Barnegat Bay watershed, from Point Pleasant to Little Egg Harbor. This year, 29 red banded ospreys were re-sighted along the coast of New Jersey.

As juvenile ospreys fledge and adult females begin their southbound migration, work to summarize data from this year is ongoing. So far, it doesn’t look like a terrible year but not a great one either. Food stress (or brood reduction) was still apparent within some coastal nest colonies, despite the lack of severe weather (nor’easters/microbursts, etc) which could affect the ability of adult males to find and catch prey.
The 2024 NJ Bald eagle nesting season is winding down and so far 221 young eagles have fledged from nests throughout the state. We know that these eagles have fledged due to the eagle project volunteers who monitor all known eagle nests in New Jersey. Being a nest monitor can be a joyful experience when all goes well and the pairs successfully fledge young. But, it can also be heartbreaking when a pair fails to hatch eggs and when adults or chicks are lost during the season. Despite the ups and downs of monitoring eagle nests the volunteers continue to be dedicated to the eagle project. I asked the Eagle Project volunteers to send me their two favorite photos from the season.

All photos were taken by trained volunteers from a safe distance using high powered scopes and cameras.
So far it has been an usual year for nesting osprey in New Jersey. This spring, the pair that has nested at our osprey cam in Barnegat Light, who arrived on time, the female did not lay any eggs. Then I heard from a woman who watches a nest near the southern end of Long Beach Island who reported the same — pair present but incubation was never observed. Another report came in from an osprey nest watcher on the Mullica River (to the southwest of LBI) who reported the same — no incubation observed. We put out a call on social media for osprey nest watchers to report anything odd like this to us (while also reporting osprey nest activity online via Osprey-watch.org). Some people reported seeing the same behavior..
There aren’t many times when you get to climb to the roof of a courthouse in a major metropolitan area. Except if you’re a raptor biologist! We recently joined NJ Fish & Wildlife’s Chief of the Endangered and Nongame Species Program, Kathy Clark and Union County staff and guests to band the four young falcons produced at a nest atop the Union County Courthouse, home to the Union County Falcon Cam.
Last fall I received a text from Kelly Scott, Resource Interpretive Specialist at Island Beach State Park about an osprey platform. She was kayaking within the Sedge Island Marine Conservation Zone and noticed one laying on its side – on a sandbar. I knew exactly which nest she was looking at. Later last year, I flew my sUAS to confirm her observation and make plans to get it back in working order before ospreys returned this year.

In coastal New Jersey, during spring and summer the recovery of ospreys is apparent. They grace the skies of most ocean front beaches from Sandy Hook to Cape May in search of prey. Their nests line our shorelines and can be found in a variety of nest structures. Today there are over 800 pairs of ospreys who nest all across New Jersey. Results from the 2023 nesting season illustrate how the osprey population continues to grow but with reduced reproductive success due to extremes in weather and reduced prey availability.

One of my favorite things about working with the NJ Eagle Project is when we receive resighting’s of New Jersey banded eagles. Especially when that eagle is in a pair and nesting. One eagle that we’ve been following over the years, is fondly named “Jersey Girl” due to her NJ origins. She was reported to us in 2014 by Linda Oughton, who has been keeping track of her and her mate since 2010.

Jersey Girl and her mate nest in Montgomery County, Pennsylvania. She was one of three chicks banded May 10th 2004 at the Hopewell West, nest which is located in Cumberland County along the Cohansey River. She was banded with green band B-64. That means that this May “Jersey Girl” will be twenty years old!
Since 2010 the pair has successfully raised and fledged a total of 20 young eagles. The pair is not yet incubating this season and Linda reports that they usually start on Valentine’s Day. The pair is well loved by neighbors and people who walk along the Perkiomen Creek, where the pair often fishes.
It’s so wonderful to know that an eagle I helped band almost 20 years ago has survived and raised 20 chicks of her own.
