The Fate of Chump: Osprey 78/D

Proof that life is never easy for young ospreys

by Ben Wurst, Habitat Program Manager

Ready to release Chump. RIP, Chump! photo by Northside Jim.

I thought long and hard about sharing this news, hence the delay in this post. In late October, we received news that a young osprey I banded this summer was re-sighted. It turns out that this bird was not your average young osprey, out of the 892 produced this year. This young bird hatched at a nest behind the Long Beach Island Foundation of the Arts & Sciences, around June 11th, a nest referred to as home to “LBI’s Most Famous Osprey Couple, Jack & Wendy.” He was banded, along with his nestlings, on July 5th. He was tagged with a red auxiliary “field readable” band: 78/D, as part of Project RedBand, which allows fellow biologists and citizen scientists the ability to identify the bird while still alive (most osprey band reports occur during mortality based events). At the time of banding, he was also given the name Chump, by Northside Jim.

A few weeks after being banded, a local resident reported a bird in distress (on the ground) at LBIF and I contacted Jim to see if he could respond. Long story short, he did and Chump was rehabbed within six weeks at Toms River Avian Care (on August 30th). After being released, we watched Chump make a strong flight around the marsh at LBIF until he flew off into the distance. We could only hope that he was strong enough to survive on his own, since he was too old for his parents to accept him back where he hatched. (more…)

CWF Volunteers Are Wildlife Heroes

NJ Osprey Project Volunteers Wayne Russell, Matt Tribulski and John King repair an osprey platform.

New Jersey ospreys have headed for warmer climates until their return in the spring. NJ osprey project volunteers are busy repairing and cleaning out nests, adding predator guards and perches in preparation for the nesting season.  It’s an endless job as there are 100’s of nesting platforms throughout the state and maintenance is always needed. These repairs keep the nests as safe as possible for the nesting ospreys.

Thank you to all the dedicated CWF volunteers!

ACTION ALERT: Support ecological management of the most valuable public resource for our coastal ecosystem and economy

The Atlantic States Marine Fisheries Commission is accepting public comment on the establishment of ecological management of Atlantic menhaden (Brevoortia tyrannus), which is a keystone species. Basically, a keystone species is one that plays a large role in the ecosystem where it lives. If a keystone species is lost then the ecosystem would dramatically change or cease to function, causing widespread effects to other species that benefit. In New Jersey, ospreys have largely benefited from a healthy menhaden population as we’ve had relatively high reproductive rates (more than double what’s needed to sustain population) over the past decade. From 2006 to 2016, the population has grown by 30% and above the pre-DDT, historic milestone of over 500 nesting pairs. Around 82% of the state population of ospreys nests along the Atlantic Coast and we observe menhaden at a huge number of nests during our mid-summer surveys. If menhaden numbers drop, then we will likely see osprey numbers follow suite, as reproductive rates will decline, as they are in the Chesapeake Bay.

Continuing To Track NJ Eagles

Saturday, September 2nd, 2017

by: CWF biologist Larissa Smith

We keep track of all re-sightings we receive of NJ (green) banded eagles. This information is important as it lets us know where eagles raised in NJ go after leaving the nest and eventually where they end up nesting. In 2017 we have had NJ banded birds sighted in NJ as well as PA and VT.

On April 15, 2017 Mary Dunham photographed NJ banded D/18 near Lake Como in Belmar, NJ.  The female was banded in March 2011 at the Manasquan Reservoir, Monmouth County. She was with another smaller adult, assumed to be a male. While Mary  watched a third adult eagle came into the area and the pair chased it away. This is an indicator that D/18 was paired up and perhaps was nesting in the area.

D/18 @ Mary Dunham

In August we received a report that D/18 was sighted once again. This time she was up near the NY- Canada border. We don’t know much about the movements of nesting eagles so we can only speculate why she made such a big move north. Perhaps she went north with a recent fledgling or maybe she was kicked out of the pair by an intruder eagle and headed north?

D/40@ Reid Hoffer

In March we were contacted by Reid Hoffer who monitors an eagle nest along a reservoir in Rockland County NY.  He was able to get a photo of a green band, D/40, she was banded May 2011 at Newton Reservoir in Sussex County. Mr. Hoffer reports that unfortunately the pair did not produce any offspring this year.

Telemetry

We are also currently tracking three NJ eagle with transmitters attached.  The New Jersey Bald Eagle Tracking project shows the movements of all three of these birds as well as their history.

Two of the transmittered birds  fledged from Merrill Creek Reservoir in Warren County, NJ. Harmony 2, has spent the last four years in a 100-mile swath of western Connecticut and Massachusetts. She fledged in 2012 making her a 5th year bird and breeding age. We suspect she’ll nest in the same area next season.  Haliae fledged in 2013 and has spent the past three years mostly around the Eastern Shore of Maryland. Perhaps she’ll stay in that area to nest? So two birds from the same nest, but one has settled to the north and one to the south.

Nacote, a male from the Galloway nest in Atlantic County, has stayed more “local” to his home area. He’s spent the last three seasons in Atlantic, Cumberland and Cape May Counties. He favors the CMC landfill and local sand pits where other eagles are known to roost and feed.

All this information helps us to locate roost and foraging areas and protect them.  It’s also fascinating to know where NJ eagles go after leaving their nest area, especially when they begin nesting. Why do some head north, others south and yet others stay near their “home” range? We don’t know, and that’s ok, it’s what makes them wild!

“Chump” is rescued, rehabbed, and released

by Ben Wurst, Habitat Program Manager

Chump, what are you doing down there? Photo by Northside Jim.

On Sunday, July 30th I woke and checked my email early that morning. I had an urgent message from Deb Traster, who lives adjacent to the Long Beach Island Foundation of the Arts & Sciences (LBIF). She said that something was not right with one of the young ospreys that fledged from a nearby nesting platform where I banded three nestlings with red bands on July 5. One was on the ground and could not take off. Fearing the worst (entanglement), she checked it out and sought help. After getting in touch with me, I reached out to my buddy, Northside Jim to see if he could get there that morning. (more…)
