Those who have followed CWF’s work throughout the years know how important bird banding can be for wildlife biologists and conservationists. The practice, which involves placing metal and/or color bands on a bird’s legs, can provide useful information about that bird’s life history, site fidelity, and movement. Typically, banded shorebirds are equipped with a unique alphanumeric code or color combination (kind of like a name tag), which enables scientists to track an individual bird throughout its lifetime. For those monitoring New Jersey’s beach-nesting bird populations, bird banding greatly enhances the quality and accuracy of our productivity data, which allows us to make better-informed decisions regarding management.
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.

Since 2018, CWF has partnered with the USFWS New Jersey Field Office in completing summer mist netting surveys for bats in the Pinelands. The goal of these surveys is to capture the federally threatened Northern long-eared bat and track these bats to maternity roosts.

On May 23, NJDEP Fish & Wildlife Supervisory Zoologist Kathy Clark and myself visited the Union County Courthouse in Elizabeth, NJ to band the three eyases that were produced by the nesting pair of peregrine falcons. We were joined by Union County staff and guests, who assisted with the banding. The nest is located on the roof of the building. As soon as the hatch made a sound, the adults took off and started to defend their nest and flightless young. As we enter their turf, we are dive bombed by the adults — it is clear that the female has become more aggressive — as she flies very close to us on the roof in sweeping dive bomb attacks. As Kathy goes to the nest to grab each young who are placed in reusable shopping bags, I use her trusty feather duster to ward off the adult female. All who enter the roof wear fall arrest harnesses and hard hats. Kathy and I know that the hard hats are not just worn for fall protection, but also from attacks from above. Both of us received bumps from the adult female to our helmets!
Two bald eaglets at the site of our Eagle Cam at Duke Farms were recently banded by biologists from Conserve Wildlife Foundation (CWF) and New Jersey Department of Environmental Protection, Endangered and Nongame Species Program (NJDEP ENSP).
This year’s banding was special, as in addition to a band the male eaglet was also fitted with a transmitter which will allow him to be tracked on our Eagle Trax page.

Kathy Clark, (NJDEP ENSP), and Larissa Smith (CWF) wrote about the experience, and the benefits of transmitters on the Duke Farms blog. Their FAQ’s are reprinted below.
“Tiny” has another successful nesting season in Connecticut

C/94 “Tiny” keeps a watch over nest in CT; 6/3/2016@ C.Pratt Didan
In 20015 we were contacted by Cyndi Pratt Didan regarding a pair of nesting eagles she has been observing in CT about 150 miles from Duke Farms. She was able to get a reading of the green band on the male C/94. It turns out that C/94 is a Duke Farms eagle from the 2009 nesting season. In 2009 there were three chicks in the nest and all were male. C/94 was the youngest and considerable smaller in the beginning as he was a week younger than the oldest chick and got the nick name “Tiny”.

His mate is also a banded bird from Massachusetts banded on June 11th, 2008. The pair nested in 2014 fledged two chicks and fledged one chick in 2015.
Cyndi reports that the pair built a new nest seven miles away from their old nest. This nest is in a pine tree on an island in a Reservoir. This season they fledged two young birds.
We thank Cyndi for keeping us updated on this NJ bird. It’s always good to get news about one of “our” chicks.

2016 Lesson Plan Winner Lauren Kurzius
Manville School District science teacher Lauren Kurzius was recognized by Duke Farms and Conserve Wildlife Foundation for winning our EagleCam lesson plan contest earlier this month! Kurzius joined wildlife biologists to help band the new Duke Farms EagleCam chicks on Monday, May 9. The EagleCam lesson plan contest, jointly organized by Duke Farms and Conserve Wildlife Foundation, called upon educators to submit lesson plans incorporating the Duke Farms EagleCam into their classrooms.
Installed in 2008, the Duke Farms’ EagleCam has provided a streaming look into the daily lives of the eagle family for over 10 million viewers. Kurzius is working with the Duke Farms and Conserve Wildlife Foundation EagleCam team to expand the camera’s potential as an educational vehicle by including her lesson plan for use in classrooms across the country.
“Duke Farms is pleased once again to support dedicated New Jersey teachers that bring wildlife ecology into their classrooms. Lauren Kurzius’ winning lesson plan (“Birds of Prey – Who Done it?”) is a terrific introduction to predator-prey interactions, patterns among organisms, and ecosystem viability while allowing them to take on the role of student detective” explained Michael Catania, Duke Farms Executive Director. “Her participation in this year’s banding of the Duke eagle chicks was one of the highlights for our staff, and certainly a thrill for her students in Manville, New Jersey to watch.”
The EagleCam became a prominent teaching tool in Kurzius’ classroom in 2013. She had begun viewing the eagles in 2011 and recognized its potential for using it in the classroom immediately. Regarding the banding process, she says it was “priceless,” adding, “I connected with educators, scientists, and environmentalists. I get to share that with my current students and my future students. When you have new experiences, it leads to authentic teaching. Maybe my experience will inspire one of my students to follow a career path in science and that makes the banding all worth it.”

CWF’s David Wheeler stated that “by exploring science with creativity and a sense of wonder, Lauren Kurzius inspires her students to connect with the natural world around us. That personal connection reveals just how much people can strengthen the environment and benefit wildlife like bald eagles, which have made an awe-inspiring comeback. The Duke Farms webcam offers Lauren’s students and so many others the opportunity to intimately experience the lives of these magnificent creatures.”
We were thrilled at the enormous response received from teachers across the state, and will continue to offer the amazing opportunity to teachers in New Jersey! Congratulations, Lauren!

Celebrating World Shorebirds Day, Sunday, September 6

As a bird nerd, I’d often look on enviously at photos of biologists posted online holding shorebirds in their “bander’s grip” – the bird’s head in between their index and middle finger, using their thumb and pinky to steady the bird, while allowing its feet to dangle freely.
I always wondered: I wish I could do that! Hold a bird in my hands. Yet I never once thought: Wait, how did the bird end up in their hands in the first place?
I certainly hadn’t thought biologists run all over the beach chasing after shorebirds like a farmer chasing chickens – I just never thought the process all the way through.
This past summer, I was fortunate enough to become part of that process and learned exactly how a shorebird ends up in a biologist’s bander’s grip. The system may surprise you, but the steps have been mastered over nineteen years of practice, each one with shorebird safety as the top priority.
Conserve Wildlife Foundation (CWF)’s Delaware Bay Shorebird Project celebrated its 19th year this summer. The team members, led by Drs. Larry Niles of CWF working with Amanda Dey of New Jersey Division of Fish and Wildlife, are all extremely passionate about what they do and care deeply for the shorebirds they are studying and protecting.
I arrived at the team’s house on Reeds Beach, along the Delaware Bayshore, early in the morning. Dr. Niles was concerned about the wind and had scoped out the safest beach for the banding that day. Our group of scientists, volunteers, supporters, interns and staff caravanned to Villas and joined our partner, American Littoral Society, at the site. We all picked up large, colorful plastic tubs, which had cloth covers that fit securely over the top of the box. The cloth cover had a Velcro pocket. We were told that these boxes would help in the shorebird “catch” that day. Larry and Mandy gave us instructions for how the banding day would go, safety tips and background information on the Delaware Bay Shorebird Project. We all listened intently and couldn’t wait for the day to begin!

Well, we waited a bit before the day truly started. Dr. Niles and his team had binoculars with them and sat down in the sand, watching the shorebirds from afar for about an hour and a half. We waited by the cars up near the houses along the beach. The reason for the long wait? Dr. Niles and his team were waiting for the perfect moment to fire the net over top of the shorebirds along the coastline.

Cannons with gun powder charges fire heavy projectiles that carry the net over the birds only at the perfect moment – when birds are catchable and none in danger. Luckily, it was not a “wet catch,” that day, as the net did not go into the water. As soon as the cannon was shot, we all spirited single file carrying our tubs down the beach, following the biologists. The biologists immediately knelt at the base of the net and started picking up birds and shouting their identification and passing them to us, as they went they rolled the net away to reveal more birds.
It was very exciting! The idea was to get the birds out from under the net and into our carrying boxes and sealed in with a Velcro flap, as fast as possible, for the safety of everyone involved.
Each bin became devoted to the same bird species, so if the first bird that was handed to us was a sanderling, we kept putting only sanderlings in our bin. Once we had several birds in our bin, our pace completely changed. We walked very slowly away from the net, keeping the bin level at all times, towards the path in the sand at the beginning of the beach, to make the journey as safe for the birds as possible. There, biologists had burlap “keeping cages” for the birds to wait in. Birds were also sorted by species into these cages.
When every bird was taken out from under the net, and sitting in their temporary burlap enclosure, we formed “circles.” Each circle was composed of about 6 volunteers led by a core banding team member. Once formed birds were handed to us and finally, I learned how to safely hold a shorebird in my very own bander’s grip!

Each bird received a metal band with a federal identification number, and a green tag with a three letter code. One person in the circle put the band on the bird and passed the bird to the next person, who placed the green tag on each birds’ leg and glued them shut. A recorder took notes on the band number and tag letters. Next, the birds’ wingspan and other data points were measured by other members in the circle. Lastly, the bird was weighed before it was released. During my trip with the banding team, we caught a large number of sanderlings and a few ruddy turnstones, federally listed red knots, and semipalmated plovers.

Holding a shorebird in my bander’s grip was an amazing experience, but what I enjoyed most of all was taking part in the science of shorebird conservation. I placed the green tags on the shorebirds, which will tell other scientists who may recapture the birds that they once traveled to New Jersey. Our circle helped collect valuable data points, which will be combined with the data from the other years of the Shorebird Project, to assess the health of shorebird populations.
I wasn’t just holding a bird, I was helping the bird have a brighter future – and that is the best feeling any bird nerd can have.
Today is World Shorebirds Day! You can help shorebirds have a brighter future today by participating in the Global Counting Day Program. Join the hundreds of participants at over 93 locations that will count shorebirds and share their sightings online. Register today!
92 Ospreys Enlisted in Citizen Science Based Re-sighting Project
by Ben Wurst, Habitat Program Manager

This is the critical time of year for monitoring our nesting ospreys. Each year biologists and specially trained volunteers, aka Osprey Banders, conduct ground surveys by boat to monitor the state population. They visit or survey the most densely populated colonies of nesting ospreys: Sandy Hook, Barnegat Bay, Great Bay, Absecon, Ventnor-Margate-Ocean City, Great Egg Harbor Watershed, Sea Isle, Avalon-Stone Harbor, Wildwood, Maurice River, and parts of the Delaware Bay. These surveys have been conducted since the early 1970s when ospreys were not so common, with only 50 pairs in 1973.
Their recovery has been quite remarkable. With an estimated 600 nesting pairs throughout the state, our ospreys are in a much better position today. Why put so much time and effort into monitoring a seemingly healthy population? Even though their population is much larger than it was decades ago, ospreys still face a variety of threats that jeopardize their ultimate survival. It’s commonly known that ospreys face very high mortality rates in their first year of life. Before even leaving the nest their young are so vulnerable. They can fall or be blown out of the nest, predated by raccoons, crows, or eagles, killed by their own siblings, or die from starvation. After they fledge, then they need to learn to find and catch prey and avoid power lines and wind turbines. Then they need to learn to migrate south and avoid being shot in the process. Once they find a suitable wintering site, then they remain in the same area for the next two years. Then they return to their natal areas to find a suitable nest site and start their own osprey family!
Today, we need your help! We cannot reach all active nests in New Jersey. There is still plenty of time to help us keep track of the state population. Citizens are encouraged to submit sightings of activity at osprey nests on Osprey Watch, a global osprey watching community. In 2013 all of the known locations for osprey nests was released on Osprey Watch’s website. As a partner with Osprey Watch, we share and use the data collected to help determine the overall health of the population, which is summarized in our annual report.
To help engage our Osprey Watchers, we started Project RedBand, a citizen science based osprey re-sighting project. This is year two of the project. So far we’ve deployed 92 red bands (out of 100) on young produced at nests on Barnegat Bay (62 in 2014 and 30 in 2015). The young that were banded last year will start to return to New Jersey in 2016. Usually young adults return later than older adults, so the red banded birds might not be seen until May or June. That’s when they’ll find areas with high prey availability and suitable nest sites. Usually males don’t stray far from their natal areas but females do. With these red bands, we hope to learn a little more about where our ospreys are dispersing to and at the same time engaging our coastal communities in osprey conservation.
