New Jersey’s Ospreys: A Symbol of a Healthy Coast

If you live along or visit the coast, then it’s no surprise that ospreys continue to thrive in New Jersey. 2018 was yet another banner year for these coastal nesting raptors. Their large stick nests depict our rivers and estuaries while they indicate that we’re doing a good job of protecting our local environment along the coast. Today we’ve published results from last year’s nesting season in the 2018 New Jersey Osprey Project Report.

Duke Farms Alumni D/99: All Grown Up

On Sunday January 13th, 2019 photographer, Bob Cook was taking photos of the ~20 eagles at a lake in a Mercer County park. He noticed that one of the eagles had a green tag on it’s right leg. After reviewing the photos it was established that the band was D/99.

D/99 is from the Duke Farms nest located in Somerset County. He and his two siblings grew up as a celebrities their every move being watched by viewers of the Duke Farms eagle camera.  The three chicks were banded on May 12th, 2014. Measurements showed that there there were two males and one female, D/99 was the youngest male.  All three fledged from the nest in June 2014.

Unfortunately, in August of 2014 we received a report that D/98, the oldest male, was found dead up in Maine.  He most likely died of injuries that occurred during a fight with another eagle. This most recent sighting of D/99 is the first report of either of the two remaining chicks. D/99 will be five years old in April and reaching the age where he will be looking for a mate and establishing his own territory.  It is always nice to know that a chick has survived to adulthood and most likely has come back to NJ to nest.

2018 NJ Bald Eagle Project Report

The Conserve Wildlife Foundation of NJ in partnership with the NJ Division of Fish and Wildlife, Endangered and Nongame Species Program, has released the 2018 NJ Bald Eagle Project Report.

“Two hundred-four nest sites were monitored during the nesting season, of which 185 were documented to be active (with eggs) and 19 were territorial or housekeeping pairs.  Thirty new eagle pairs were found this season, 20 in the south, nine in central and one in the north.  One hundred-twenty-one nests (66%) of the 182 known-outcome nests produced 172 young, for a productivity rate of 0.94 young per active/known-outcome nest. The failure rate was well above average with 61 nests (33%) failing to produce.  The Delaware Bay region remained the state’s eagle stronghold, with roughly half of nests located in Cumberland and Salem counties and the bayside of Cape May County.”

The number of active nests has increased while the number of young eagles fledged has decreased since a high of  216 young fledged in 2016.  During the 2018 eagle nesting season there was an abundance of cold, wet, windy and snowy weather which was the cause for a portion of the nest failures. As the eagle population increases, there are  more eagles competing for territories. This can also be a contributing factor in nest failures.  NJ is still in the range of 0.9 to 1.1 young per nest which is needed for population maintenance with a productivity rate of 0.94 young per known-outcome/active nest in 2018. The 2018 NJ Eagle Project Report has all the details on the project including telemetry, re-sightings and recoveries.

The success of the eagle project is due to the tremendous dedication of the NJ Eagle Project Volunteers. They monitor the nests in all types of conditions and education people about the eagles with enthusiasm.

THANK YOU

 

 

Bald Eagles and Lead: A Deadly Mix

Monday, November 19th, 2018
by Larissa Smith, CWF Biologist
Lead poisoning continues to be a serious issue affecting Bald Eagles today.  CWF and ENSP biologists produced a brochure to educate hunters about this issue and ask for their help. Below is an excerpt from the brochure. Please view the entire brochure and pass along to anyone you know who is a hunter.
One person can make a difference!

Thank you.

Eagle with lead poisoning at Tri-State Bird Rescue@Erica Miller

“Bald Eagles have made an amazing recovery in NJ since the 1980s. Today the eagle population still faces challenges and one of those is lead poisoning. Lead in the environment is dangerous to eagles as well as humans, and is often deadly. Unintentional poisoning of eagles can occur when they scavenge gut piles from deer or other game species shot with lead ammunition. It takes just a tiny fragment of lead to sicken and kill an eagle. Each year avian rehabilitators receive eagles that are diagnosed with lead poisoning and most will die. There is no good treatment for lead poisoning.”
