Video from the Field: Osprey Platform Install

Ensuring Osprey Platforms Remain Resilient

by Ben Wurst, Habitat Program Manager

On a brisk November morning, a couple dedicated NJ Osprey Project volunteers joined myself and CWF Biologist Larissa Smith to install an osprey platform on the coastal saltmarsh of New Jersey. The new platform was installed to replace a very old and unstable platform that fell this summer. The new structure is more than twice the size of the old one and will give the nesting pair, who return in the spring, a much more resilient nest site. As you can see from the video above, it takes a bit of strength to raise up a 16′ tall wood nest platform. We decided to slow it down when WCC Volunteer, Wayne R. gives it a final push. (more…)

Documenting the presence of plastics in osprey nests

The threats are real and these photos should alarm you!

As I work to finalize data from this summer’s osprey surveys, I wanted to look back and highlight an important observation: more plastic is being found and recovered from active osprey nests. I guess it’s no surprise when you hear that “18 billion pounds of plastic waste flows into the oceans every year from coastal regions.(more…)

Insight Into Important (Bio)Indicators: Ospreys

by Ben Wurst, Habitat Program Manager

CWF Osprey Banding Apprentice Northside Jim holds a young osprey, 13/K, after banding.

Mid-summer marks the nestling period of nesting ospreys, a coastal raptor, whose diet consists mainly of fish. As a state that’s heavily influenced by its location along the Atlantic Ocean, they play a critical role in our coastal ecosystem. Ospreys are important bioindicators of the health of our coastal waters, through the lens of their prey, where pollutants are biomagnified through the food chain. As we consume many of the same fish, they show the effects of these pollutants long before humans, so the health of their population has implications for our coastal waters and us! (more…)

Tracking NJ Eagles: Harmony 2

“Harmony 2”, photographed in CT and doing well.

Harmony 2@ Andrew Drummond

Andrew Drummond captured this image of “Harmony 2” on Memorial Day in Marlboro, VT.  She was banded as D/64 and outfitted with a transmitter May 29th, 2012 at  Merrill Creek, Warren County.  We have since been following her movements on Eagle Trax.  She fledged in 2012 and spent her first winter on the lower Chesapeake Bay before traveling to Maine. She has spent the last five years in a 100-mile swath of western Connecticut and Massachusetts, and now into southern Vermont. She is of breeding age so we suspect that she will be nesting in the area next season.

Identifying “Bandit” at Pete McLain Osprey Cam Nest

The Amazing History of a Breeding Adult Male Osprey at Island Beach State Park

Around 3% of ospreys who were banded with USGS aluminum bird bands as nestlings in New Jersey are re-sighted after fledging or leaving their nest. Most of those recoveries or resightings are centered around mortality based events where a bird is injured or killed and the band is then close enough to read. Since the numbers on the leg bands are so small, it is often hard to read when they are still alive. However, when enough photos are obtained or a camera is installed on a nest then the likelihood of reading the band on a live bird increases.  (more…)
