Re-sighting New Jersey Eagles

Wednesday, April 10th, 2013

Looking for green bands.

by: Larissa Smith, wildlife biologist/volunteer manager

One way we can track eagles is with transmitters which I’ve discussed in previous blogs. Since 2011 three eagle chicks have been outfitted with satellite transmitters to track their movements. Two of the birds have since died. To follow the movements of the third eagle go to http://www.merrillcreek.com/eagletracking.html

Another way to track eagles is by banding them.  The NJ Endangered and Nongame Species Program has been banding eagles with green (NJ specific) bands since 1987.  Eagles are banded when they are six weeks of age and get a green NJ band on one leg and a silver federal band on the other.  The state band has a letter over a two digit number. The band information is entered into the National Bird Banding Lab database and when someone finds an injured or dead eagle they can report the band. Most of the information that comes in from these bands are from dead or injured birds. The bands tell us when and where the the bird was banded. By using spotting scopes people can sometime see that a bird has green band but many times are unable to read the number.  We know that  23 pairs of eagles nesting in New Jersey have at least one bird in the pair that was banded in NJ.

Sometimes we are lucky to get re-sightings from photographers with high powered lenses who can focus in on the band.  Just in the past week we’ve gotten three sightings of NJ birds.  One eagle has been seen on Long Island with a green band and reported by Peter Stegemann. He has seen this bird all last summer and fall with another eagle and they might be nesting this season. This would be the first pair of eagles to nest on Long Island since DDT wiped out the eagle population. By zooming in on the photo ENSP principal biologist Kathy Clark was able to read the letter and first number as C/8.  The second number couldn’t be read but by going through the banding records it was determined that this eagle was banded in 2009 at the Princeton nest.

Another NJ banded bird (D/64) was photographed by Justin Pursell in Schwenksville, PA on April 7th, 2013. The eagle hasa nest in the area.  The bird was banded May 10, 2004 at the Hopewell West nest in Cumberland County.  Kristen Nicholas took a photo of a third  year NJ banded bird at Lake Tappan Northern NJ/Lower NY on March 20, 2013. The green band is D/39  a third year male which was banded in 2011 at the Oradell Reservoir in Bergen County NJ.

While it’s great to get re-sightings of NJ banded birds we don’t want to get them at the expense of the eagles. These photos were taken by photographers with high powered lenses. People should view eagles from a safe distance so as not to disturb them, especially when they are nesting.  Disturbance to a nest can cause the eagles to abandon the eggs/young or cause the young to prematurely jump from the nest.

Volunteers Survey New Jersey’s Eagle Population…

…during the 2013 Midwinter Bald Eagle Survey

Every January NJ participates in the National Midwinter Eagle Count.   Volunteers surveyed for eagles statewide during the weekend of January 12th & 13th.    Due to dense fog the visibility was poor in many of the survey areas but despite this the total count was  297 bald eagles.  This is 38 less than 2012′s high count of 335 bald eagles.  Four golden eagles were also counted during the survey.

2013 Midwinter Eagle Survey Results

  • Southern NJ: 264 bald eagles
  • Northern NJ: 33 bald eagles
  • Total bald eagles: 297

Thank you to all volunteers who participated!

February is a great time to get out and view eagles in New Jersey.  So far twenty-one pairs of eagles are incubating (on eggs) while others pairs are busy getting ready for the season.  Not only can you spot resident birds this time of year but wintering eagles as well.  The Cumberland County Winter Eagle Festival takes place this Saturday the 9th. This is a good opportunity to see eagles and other raptors and learn more about them.  I’ll be there at the CWF table so stop by and say “Hi”.

Oystercatcher Technician shows diversity of tasks in wildlife conservation

By Alfred Breed, CWF Technician

My official job title with Conserve Wildlife Foundation of New Jersey is  “American Oystercatcher Technician”.  As such I am tasked during nesting season with monitoring Oystercatcher nesting sites, and during migratory season with locating flocks of Oystercatchers, counting them, resighting marked birds in each flock, recording data of field survey results and reporting our NJ counts and resights to a central database that holds data from the other reporting states in the migratory flyway.

As is usually the case in any job that has a “description”, the phrase “and other such tasks as assigned” is included as a catch-all for things that aren’t specifically listed in the description, but can be an important part of the duties of the position nonetheless. In my case these ancillary tasks are different each day, and often involve three of my favorite things: wildlife (of course!), science, and gear.  Working around my Oystercatcher surveys, which can only be conducted at high tide, I might be tasked to go to a location anywhere in the state and survey for a particular species of plant or animal; or to site select, construct, install, use, maintain, and troubleshoot various types of data collection or other equipment throughout South Jersey.

Trucks, trailers, boats and kayaks are the big-ticket items that I use every day, but I’m lucky enough to use a large variety of other cool tools and equipment as well. Driving is often a big part of my day, with travel times between sites eating up significant portions of the workday.  Sometimes I’m a wildlife EMT or ambulance driver, saving sick or injured animals from their immediate predicament and/or transporting them to various certified rehabilitation facilities located throughout the state.

Best of all is when I’m asked to assist visiting scientists or other conservation partners in their work, which can mean bio-sampling or banding.  Direct human/wildlife interaction is only appropriate when it is  for valid scientific or conservation management purposes, and is sanctioned and a permit issued by the appropriate governing body.  To be a staff member and so to be included in these sanctioned and permitted activities is a rare privilege indeed.

Each day is different, always interesting, occasionally exciting, and always personally rewarding as I play a small part in the management of threatened and endangered wildlife and the habitat that we share.

Allaire Nature Center: We are open for business!

Tuesday, June 19th, 2012

by Charlene Smith, Allaire Nature Center Manager

Hi! My name is Charlene Smith and I am the manager at Allaire Nature Center. I am a recent graduate of Rutgers University where I majored in Ecology & Natural Resource Management. I have spent half my life in Montreal, Quebec, Canada and the other half in New Jersey and have been pleasantly surprised at the history, beauty, and diversity of this state. I have a passion for the outdoors and love discovering all the wildlife and various landscapes that New Jersey has to offer.

I am excited to kick off a new season of adventuring into the wilds of Allaire State Park.  Tucked away in the woods at the edge of a pond, I have always considered Allaire Nature Centerto be a hidden gem that only a few people have had the chance to experience.  

CWF is offering many nature based programs that help to get people out in the field and experience wildlife hands-on.  This weekend, come and explore the pond and stream or take a quiet bird walk.  Check out our programs page. 

Many people come to Allaire and can’t believe what a beautiful park it is and that it took them so long to come visit. They always vow that they will return again soon and spread the word to friends and family.

So, what are you waiting for? Come spend the whole day at Allaire! Make sure you bring your walking shoes and curiousity – and stop by the nature center and say Hi!

Photo From the Field- Horseshoe Crabs

Horseshoe crabs have been spawning since early May along Delaware Bay beaches.  This is good news for the shorebirds that have been coming to fill up on the eggs before their long flights.  Researchers have reported that the birds have been gaining the weight needed for their flights and a group of  birds have already left the area.
