Birds in better condition than last year but still face an ecological roulette

With the stopover period winding down, we can say the red knot and other shorebird species left the bay in better condition than the disastrous condition of last year. So what does it mean?

First, the last four years have been a sort of ecological roulette for the birds. Horseshoe crab numbers remained at only 1/3 the potential population possible on Delaware Bay leaving birds at the mercy of good conditions to get enough eggs. Last year, water temperatures stayed low during the mid-May depressing the spawn and the density of eggs. Although the average was 8000-eggs/square meter, there were less than 2000 eggs/ meters square in the month of May. (more…)

Good horseshoe crab egg densities draw 34,500 Red Knots to the bay

The best news is a direct consequence of these good conditions, the number of knots and turnstones increased this year. Our season-high estimates show that there are 34,500 knots in the bay and 21,000 ruddy turnstones. These may be the highest counts on the bay in at least 15 years.

Why? At first one would conclude the increased numbers on the bay represent a real increase in the size of the population, but it is not. Shorebirds need time to respond to improving conditions because they are relatively slow breeders, as are most Arctic breeders. Knot numbers on Delaware Bay basically depend on the availability of crab eggs. In bad years, numbers go down because birds come to the bay and leave quickly. (more…)

Record Breaking Return of New Jersey Osprey

Male osprey makes epic return to nest along Delaware Bay; turns seventeen this summer!

by Ben Wurst, Habitat Program Manager

Photographer Brian Kushner has photographed this bird over the past ten years. Just this past week he confirmed his return to his nest by ID’ing him by his band # 0788-45514. Click to view large on Flickr. photo by Brian Kushner.

The spring arrival of the North American osprey (Pandion haliaetus carolinensis) to their nesting grounds in New Jersey was delayed slightly due to prevalent north winds. As we saw many birds begin to arrive to their nest sites, which they return to year after year, we were particularly interested in the return of one very special osprey. This individual, if he survived the winter would be the oldest living osprey ever recorded in New Jersey to be observed on his nesting grounds. Ospreys face many threats and their life span averages around 8-10 years, but some can reach 20 years old.

We would not know how old this bird is without the USGS bird band that was affixed to his left leg before fledging in the summer of 2001. Photographer Brian Kushner, who has been watching this nest for the past 10 years, was able to photograph the band, which allowed us to track down his origins. He was banded on July 5, 2001 before he could fly. The nest was less than 5 miles away from where he currently nests along the Delaware Bayshore. Typically it is very difficult to ID birds by their USGS bird bands, and most recoveries or sightings of bands occurs during an injury or death, but Brian’s been able to use his photography equipment to positively ID this bird. Banding data shows that males return as adults to nest in very close proximity to their natal areas while females tend to wander further away to nest.

Ospreys are currently laying eggs and starting incubation, which occurs right after the first egg is laid. Nests with eggs and young are protected from disturbance during this time, and established nests cannot be removed without consulting with NJ Fish & Wildlife and USDA Wildlife Services. Please refer to our “Living with Ospreys in New Jersey” guidance document for more information.

Costume parade and live wildlife highlight Leonardo Nature Center grand opening

Thursday, November 9th, 2017

Witches, ghosts, ghouls, bats – and even dogs in costume – helped celebrate the grand opening of the new Nature Center, a partnership between Conserve Wildlife Foundation of New Jersey (CWF) and the New Jersey Division of Parks and Forestry.

Over 200 people visited Leonardo State Marina on a gorgeous autumn afternoon to enjoy the Halloween costume contest, pet parade, pumpkin painting, and light refreshments.

 

Yet the tiniest creature of all may have been the most memorable –

a live big brown bat. CWF wilflife ecologist Stephanie Feigin showed the rapt families the unique adaptations that allow bats to fly, roost, and use sonar, as well as the surprising skeletal similarity between a bat’s wing and a human hand.

 

Maggie Mitchell, Superintendent at Leonardo State Marina, had this to say, “The Marina’s new Nature Center and partnership with Conserve Wildlife Foundation of NJ will provide continued education to the Bayshore Area and expand on our presence in the community, many residents were grateful for this event and we look forward to hosting additional events in the future.”

This partnership is designed to educate the public about important coastal habitat and diverse wildlife species that utilize the Raritan Bayshore area.  The grand opening allowed visitors of the center to get up close and personal with both local species like diamondback terrapins, and invasive species like the red eared slider. In addition to those two turtle species, the Nature Center also hosts a corn snake, bearded dragon, touch tanks and other activities for children to enjoy.

 

“Children and adults alike are often amazed to find out some of the wildlife species that live right in their backyards and neighborhoods – and now our Nature Center allows visitors to experience those incredible animals up close,” said CWF Director of Education, Stephanie DAlessio. “We are so excited to create a new generation of environmental stewards to help protect our coastal habitat and the wildlife that shares it with us – all while having fun connecting local families to nature.”

 

Just south of New York City, New Jersey’s Raritan Bayshore hosts an impressive wildlife diversity for such a densely populated metropolitan area. Leonardo State Marina is located in the Leonardo section of Middletown in Monmouth County, west of Sandy Hook and just north of Route 36.

 

The Nature Center is open daily from 10 am to 3 pm, with extended hours until 6 pm on Fridays. CWF and Leonardo State Marina also offer school field trips, summer programs, and special events throughout the year.

You can learn more about the Nature Center at or to inquire about school or community programs, call 732-291-2986 or email Stephanie DAlessio at Stephanie.dalessio@conservewildlifenj.org.

Newsworks: Why the Red Knot lives and dies by what happens in NJ
