Marine debris (specifically plastics) have become a serious problem in coastal areas throughout the world, especially in the Pacific Ocean where gyres create large floating “garbage patches.” I work out on the back bays and salt marshes throughout the coastal region of New Jersey as I help to monitor and manage ospreys and their nesting platforms. Every time I’m out I encounter trash. Most of it accumulates along the wrack line on the higher portions of the marsh where storm surges, high winds, and during spring tides (during full and new moon phases) push it onto the marsh. This debris then makes its way into the nests of ospreys because this is where they collect most of their nesting material.
We recently decided to have a photo contest to choose a new cover photo for our Facebook page. We wanted to do this as a way to engage people with our work and generate some conversations around the wildlife photographs we received.

We were thrilled to receive an amazing response to the contest and today we opened voting on 89 photos submitted from across New Jersey. Yes, we received a lot of photos of ospreys which speaks to their photogenic quality and the fact that many photographers are down the shore this season. We also received photographs of a wide range of species – mostly birds but also reptiles, amphibians, insects and a mammal.
The album of 89 photos represents New Jersey’s biodiversity in all its glory. The album also represents New Jersey’s geography and clearly illustrates how habitats occur across the state from the busiest beaches to urban parks and from National Wildlife Refuges to suburban backyards.
Check out our Facebook page and the cover photo contest album. Be sure to LIKE our page and cast your vote for a new cover photo (just “like” the photos you want to vote for). You can vote for as many photos as you want.
The photo with the most likes becomes our cover photo. Voting closes on Friday at 12:00 pm.

In June of 2011 two chicks (male & female) from the Merrill Creek Reservoir eagle nest in Warren County were fitted with solar-powered transmitters that are monitored via satellites. The males movements have been tracked for over a year starting when he left the nest in June. You can see the eagles movements by going to: http://www.merrillcreek.com/eagletracking.html In September the male flew as far West as Harrisburg, PA and in January spent a few days at the upper Chesapeake Bay in Maryland. He has spent the majority of his time in New Jersey and Eastern Pennsylvania. It is very interesting to see where the eagle is spending his time and the type of habitat he is using. When you go to the map you can zoom in to get a close up look at his locations.
Unfortunately the female chick died in October due to starvation. She tested positive for West Nile Virus which could have contributed to her death. The transmitter was recovered from the female and in May of this year the transmitter was placed on the largest of three chicks, a female, in the Merrill Creek nest. She just recently left the nest and is still in the area of the nest taking short flights. To follow her movements go to http://www.merrillcreek.com/eagletracking.html

Conserve Wildlife Foundation Intern, Nelson Melendez, and I recently had an opportunity to assist Endangered & Nongame Species Program Biologist Sharon Petzinger in her research on golden-winged warblers, a species just added to the state’s list of Endangered species this year. We were banding males which had been observed previously and had already claimed breeding territories. They were being banded in order to obtain data regarding their distribution and habitat use, as well as other life history information.
Only males were being targeted for banding. Males are territorial during the breeding season and do not tolerate the presence of other male golden-winged warblers. Therefore, in order to catch a male, we would use their own territorial instincts to lure them into a mist net (a mist net looks a little like a volley ball net with much finer netting which becomes invisible to birds if set-up properly).
Once a mist net was set-up near a known golden-winged’s territory, Sharon used a custom-painted “toy” bird to play the role of an unwelcome male visitor. She also used a call play-back, a recording of a male golden-winged’s song. The song would lure the male near the net, and the decoy should bring him right into the net.
We went to several locations in northwest New Jersey where golden-winged warblers had been observed earlier in the year to set-up the mist net. On this particular day, however, luck was not with us for no golden-winged warblers were caught. Several other species were captured however, such as a veery, chestnut-sided warbler, and a Brewster’s warbler. The Brewster’s warbler is actually a hybrid of a golden-winged warbler and a blue-winged warbler. Another hybrid form between those two species is known as Lawrence’s warbler.

The veery and chestnut-sided warbler were released from the net unharmed. Before the Brewster’s was released, a small aluminum band was placed on its leg and measurements such as wing length and weight were taken.
Warblers are often an overlooked group of birds by some birdwatchers due to their small size and relative difficulty in observing. They are stunningly beautiful however, which becomes apparent when you have the opportunity to view them up-close. They are a very diverse species group with a variety of interesting life histories. There is currently one species (the golden-winged) listed as Endangered in the state and 11 additional species listed as Special Concern. To learn more about them, please visit our on-line field guide links below.

The rusty-patched bumble bee, a species believed to be extirpated within New Jersey.
Conserve Wildlife Foundation of NJ (CWF) has just launched several new web pages devoted to those species which have been lost from New Jersey (and the world in some cases). Ten species are profiled – five which are extinct and five which are extirpated from the state. Although their stories are sad, they are also warnings for what may happen to other species which are currently struggling to survive within the state, especially those already on the state’s endangered species list. CWF’s wildlife conservation projects attempt to avoid more species becoming extinct or extirpated in New Jersey.
CWF would like to thank Joseph Wotasek, a junior at Centenary College majoring in Graphic Design, who volunteered his time and skills in creating images of the ten profiled species for the new web pages.
By now most ospreys are back from their wintering grounds in Central and northern South America. Generally the older more experienced birds return first and the younger inexperienced adults follow. Over the past month I’ve been very busy with platform repairs and installations throughout coastal New Jersey. You may not be aware but I maintain a huge number of nesting platforms. In just the past couple weeks I’ve worked as far south as Avalon (where I lead a group of students and their parents from Collingswood to replace an existing platform) and as far north as Bayonne (where I installed 3 platforms with local middle and high school students). Both were memorable experiences for both myself and many of the students. Most of them had never been on a boat or ever had the chance to walk on the saltmarsh.
Maintenance of existing platforms is critical to the continued recovery of ospreys. Over time (and in some cases, not much time) the condition of these nesting platforms is degraded, mainly by the environmental conditions where they’re placed. For the most part the fasteners are what go first from contact with high levels of moisture in the air, after that, the wood decays (unless a pressure treated or cedar wood is used). One way to help prevent the decay of platforms is to use marine grade stainless steel screws, galvanized bolts, and treated lumber. If we were to lose a large portion of the available nesting platforms in a given year then the population would suffer, so it’s important to make sure existing platforms remain in good condition.
Last week I got out to the “Wildlife Drive” at Forsythe NWR in Oceanville to repair a platform. The platform top had lost a side and could no longer hold nesting material. I built a new top out of salvaged wood that I collect and installed it on Thursday afternoon. The next day a male osprey began to place nesting material in the freshly repaired platform. Talk about perfect timing!
If you’re interested in helping us to maintain osprey nesting platforms, contact me about our new program to “Adopt a Platform.”

To coincide with the NJ Department of Environmental Protection’s (DEP’s) adoption this week of revised lists of endangered, threatened, and special concern species in the state, the DEP’s Endangered and Nongame Species Program released an updated version of the Landscape Project earlier this week.
The Landscape Project is a mapping tool, created using Geographic Information Systems (GIS), which displays wildlife habitat throughout the state ranked according to the rarity of the species which occur in specific patches of habitat. The highest rank (5) is used to indicate habitat for those species which are federally endangered or threatened. Rank 4 is used for state endangered species, rank 3 for state threatened species, rank 2 for species of special concern, and rank 1 is for suitable habitat patches for which no rare species documentation currently exists.
The Landscape Project Version 3.1 report.
The updated version of the Landscape Project is known as Version 3.1 (V3.1) and it replaces both Version 3.0, which covered the Highlands region only, and Version 2.1, which was applied to the remainder of the state. Both previous versions were released in 2008.
Several changes have been in the methodology and source data used to create this latest version of the Landscape Project. First, V3.1 is based upon 2007 Landuse/Landcover data, as opposed to the 2002 data used in previous versions. Second, over 3,500 new rare species records were used in V3.1 and the newly adopted endangered, threatened, and special concern status changes are reflected. Also, species not included in previous versions, such as whales, sea turtles, and freshwater mussels, are included. More detailed information is also available in V3.1 such as the type of occurrence documented (nest, foraging habitat, etc.) and the last year that the occurrence was documented.
Since creation of the first version of the Landscape Project in the mid-1990’s, it has been a valuable tool for conservationists, land managers, state and local governments, as well as others. Municipalities often refer to it in creation of their Environmental Resource Inventories (ERIs) and land trusts often use it to target areas for open space acquisition.
It’s hard to believe that in another 6-7 weeks ospreys will be back in New Jersey and ready to begin another nesting season. Over the next few weeks we’ll be busy making repairs to existing nests, moving platforms to more suitable locations, and installing new nests to replace old derelict platforms. We maintain a huge portion of the available nest platforms along the coast and do so with no state funding! All of our funding comes from private donations from individuals, foundations, or grants. Since our osprey project began in 2006, we have installed more than 100 nesting platforms throughout New Jersey. What’s new? This winter we have plans to install three new structures in Bayonne with local high school students. This will be the furthest north that we have ever worked with ospreys. It’s a new and exciting endeavor for CWF. If you enjoy viewing ospreys during your visits to coastal areas of New Jersey during the summer, please consider making a donation today by sponsoring the placement of a platform or by adopting an existing platform.
Bald eagles are beautiful birds so it only makes sense that people want to get a closer look at them. But often people don’t realize that by innocently stopping to look at an eagle nest they are putting the eggs or young in jeopardy. As the New Jersey eagle population increases eagles are starting to nest in closer proximity to humans and human activity. Any activity that causes the eagles to change their normal behavior is “disturbance.” People walking too close to the nest to get a closer look or take photos will cause the birds to get off the eggs or leave the young unattended. This leaves the eggs or young exposed to the elements and predators. The safe distance for viewing is at least 1,000’ from the nest site. If the birds are looking at you then you are too close.
The best way to see what goes on at an eagle’s nest without the chance of disturbing the birds is to watch them online. The Duke Farms eagle nest site has had a camera streaming the picture since 2008. This provides an up close and personal view that you cannot see from the ground. The Duke Farms eagle cam should be streaming live in the next few weeks. To view the eagle cam go to www.conservewildlifenj.org
If you have any questions about eagles or their nests or would like to report a nesting pair, please contact Larissa Smith.
“Essential Life,” a new art exhibition at the New Jersey State Museum in Trenton is one artist’s response to the decay of our environment and its impact on the indigenous wild creatures that once lived there. Tricia Zimic champions these animals, both in her exquisite sculptures and paintings and through her work on an ambitious conservation project on a 2,110-acre site in New Jersey. Zimic creates pieces that are startling and provocative. Through painting, clay, fiberglass, and found objects, she depicts creatures that have been displaced by urban and suburban sprawl: a black bear and its cubs foraging for pizza in the meadowlands, a red wolf traversing a highway or owls inhabiting a metal beam. Zimic offers viewers examples both of animal resourcefulness and population collapse.
Tricia Zimic trained at the Parson’s School of Design where she studied with artists including Maurice Sendak and Frank Giorgini. Her ceramic work is installed in public and private collections worldwide. Prior to starting her career in fine arts, the artist worked for many years as an illustrator of young adult books including the iconic Nancy Drew series. Through her current work in narrative art, Zimic seeks to communicate a message of renewal and conservation. We hope you will have the opportunity to view Ms. Zimic’s 35 inspirational sculptures and paintings. The exhibition will run until February 19, 2012, at the New Jersey State Museum, located at 205 West State Street, Trenton, NJ. Open Tue- Sat. 9 am – 4:45.
