Twins! Two osprey eggs hatch overnight!

by Ben Wurst, Habitat Program Manager

Overnight two osprey eggs hatched at the Osprey Cam nest inside Edwin B. Forsythe NWR in Oceanville on day 40 of incubation. Ospreys exhibit asynchronous hatching or they hatch in the order they are laid. This ensures that the oldest and strongest young survive if there would ever be a shortage of prey. The third egg should hatch within the next 2 days.

You can tell when osprey eggs hatch by the behavior of the sitting adult. They sit higher, with their wings down and they are a bit more concerned with the young that sit beneath them. Young are born semi-altricial which means that they are downy and can open their eyes, but they require very close parental care.

The Return of Bald Eagles in New Jersey

Conserve Wildlife Foundation Releases New Story Map: “The Return of Bald Eagles in New Jersey”

Bald Eagle Story Map

Today, Conserve Wildlife Foundation of New Jersey (CWF) announced the release of “The Return of Bald Eagles in New Jersey” a Story Map that provides a new way to visualize the increasing number of bald eagle pairs nesting in New Jersey over time.

 

For years, CWF has worked closely with the New Jersey Endangered & Nongame Species Program (ENSP) to track and restore the bald eagle population within the state. It has been a rewarding experience for all involved to witness the return of bald eagles to the garden state, and now the public can appreciate the scope of their return as well.

 

The recovery of bald eagles nationally and in New Jersey is fairly well known, but some may not realize that as recently as the mid-80’s there was only a single pair of nesting bald eagles in all of New Jersey. The ban of DDT, combined with restoration efforts by ENSP biologists, resulted in population increases to 23 pairs in 2000, 48 pairs by 2005 and 82 pairs in 2010.

 

In 2014, there were a record 146 active bald eagle pairs nesting in New Jersey. This year, 190 nesting territories are being monitored and currently 88 chicks have been reported at 52 nests; it is still early in the season so we don’t have a count for all nests yet.

 

“The Return of Bald Eagles in New Jersey” Story Map displays the locations of all the known active bald eagle nests in New Jersey from 1985-2014. Users can choose to view the nests active in a single year or over a longer period of time. By choosing a one year interval and beginning in 1985, it’s possible to watch as nests multiply from a single nest in Bear Swamp to densely populating the Delaware Bay coast and spreading across the southern portion of the state and eventually into almost every county of New Jersey. In 2014, the only counties in New Jersey without an active bald eagle nest were Essex and Hudson.

 

The Story Map also highlights “featured” nests, or nests of special significance, including the Duke Farms nest which has been featured on a webcam since 2005 and the Millville nest where a juvenile eagle was fitted with a GPS tracking device in 2014. These featured nests include more information, pictures and links to pages that explore related projects in greater depth.

 

As the bald eagle population has reached record numbers in New Jersey, the raptors have expanded into non-traditional parts of the state, providing more and more people with a chance to glimpse this iconic species. This map highlights the ongoing success of conservation efforts and illustrates that whether you realize it or not, you’re never very far from a bald eagle nest in New Jersey!

SNOWstorm at Island Beach State Park

Snowy Owls in Seaside Park, New Jersey

By: Guest Blogger Eric Chandler, Wildlife & Nature Photographer

Why do snowy owls from the Arctic migrate to New Jersey? I was determined to photograph these beautiful creatures, as well as research why snowy owls return to Island Beach State Park (IBSP) every year.

 

The migratory snowy owl population has been spotted all along the coast of New Jersey. Popular hangouts include Sandy Hook, Island Beach State Park, Long Beach Island and even further south as all the Atlantic City. Snowy owls have also been spotted as south as North Carolina.

 

Unlike other raptors, snowy owls spend the majority of their time sitting, as they hunt for prey from the ground. Their unique ability to rotate their head up to 270 degrees allows them to sit in one spot and scan large land areas for prey. The sand dunes at Island Beach State Park provide owls with an opportunity to scan for prey from a seated position, while elevated. Extreme winds are also present on ISBP; the offshore and onshore winds produce some pretty wicked combinations, which give snowy owls that at home feel.

 

The only real threat to snowy owls at IBSP is human disturbance. Like all raptors, it is illegal to hunt or trap snowy owls. Even though they aren’t hunted with rifles, they are hunted by photographers, who may step on dunes. I can’t express how many times I’ve watched snowy owls take off due to people getting too close. I’m thankful that they still return instead of finding a new migration home. Occasionally, helicopters fly overhead and the owls just watch them in confusion.

Don’t be fooled by the size of snowy owls; these birds have wingspans up to five feet and reach up to two feet tall. With such great size, snowy owls are able to hunt ducks, geese, and even large waterfowl if need be. Small rodents such as lemmings and hares are their favorite, they consume over 1,600 lemmings a year! IBSP features a wide variety of prey on their local menu such as squirrels, mice and small birds. Unfortunately, in the three seasons I’ve spent studying and photographing snowy owls, I have yet to witness a snowy owl eat. Snowy owls are diurnal, which means they are active during both the day and night. It never clicked in my head, but if you think about it, during many months in the arctic there are 24 hours of sunlight, which explains why they are diurnal. During migrations, they mostly hunt late in the day.

 

Over the past three seasons of photographing the female snowy owl, I never spotted a male, until this year! To my knowledge, this is the first year the male has been spotted at IBSP. The female is very beautiful, with dark markings throughout her pure white feathers, and bright, cat-like yellow eyes. I could photograph her for days. As I was packing up after photographing the female one afternoon, I saw a massive heard of photographers with their bazooka lenses. They must have spotted something pretty important, so I had to see. Could there be two female snowy owls? Once I arrived, I could not believe my eyes, a pure white snowy owl. Now, I love using the term majestic when it comes to wildlife, it’s a very powerful adjective. This male snowy owl surpasses that adjective for sure. It’s so hard to put into words how beautiful this creature is when seeing it right before your eyes, in order to appreciate its beauty. From his ability to spin his head up to 270 degrees, to seeing him squint his yellow eyes at you. His beauty almost demands to have his photograph taken. The stunning glow of the solid white plumage reflecting off the sunlight was a sight to see. I believe he enjoyed the paparazzi coverage; he wasn’t disturbed at all and sat with us for hours. For weeks after that day, every photographer that I bumped into and had not seen him since.

 

On an early Sunday morning, after shooting the female owl for three-four hours with about twenty photographers, I decided to venture a little bit and search for the male. If you’re not familiar with Island Beach State Park, it is a narrow, 10-mile barrier island with only one road. It’s very easy to get in the car and drive from parking lot to parking lot, but your chances of missing the wildlife are extremely high (many people also acquire a driving on the beach permit.) For me, I love being out in sub 20 degree temperatures, admiring the peaceful empty beach and watching groups of ocean birds play tag with each other. After four miles of walking, hoping to spot the male owl, all of a sudden this huge white bird starts flying towards me. He literally landed on top of a dune right in front of me! I spent the remainder of my day with him and captured some the best photographs of my career.

Underneath multiple layers with the cold wind blowing in my face on a gorgeous beach without a cloud in the sky, the sun to my back, a prime photography setting, and not a person within miles of my view, this was my sanctuary. If you want to capture the award winning photograph, you must learn patience and be respectful of the wildlife. Don’t chase after wildlife, they will come to you when the time is right. If you didn’t get your opportunity today, you will in the future.

 

So, now we know why this pair of snowy owls enjoys migrating to Island Beach State Park each year. They have plenty of mammals and birds to prey upon, elevated sand dunes to hunt from with almost no threat from larger predators. A few years ago, there was a eruption of snowy owls that traveled the coastline. Researches said this rare abundance of snowy owls usually occurs every 30-40 years! This was due to a large population of lemmings in the Arctic, prior to migration seasons. I find it very interesting that in Paleolithic caves in France, drawings of snowy owls were created over 40,000 years ago. That makes them the one of the oldest recognizable bird species show in in pre-historical art in the world.

 

From drawings in a cave, to photographs that I capture, it’s pretty awesome to share the appreciation of snowy owls from thousands of years ago. They are beautiful creatures and I look forward to their return each winter. Snowy owls migrate back to their homes in the tundra in late March, early April. With only a few months left, get out there and search for snowy owls at your local beach, but please be sure to respect the wildlife, and stay off the dunes!

Eric reports that roughly three-four weeks ago the pair of Snowy Owls mentioned in this post left Island Beach State Park. Recent reports of large amounts of snowy owls in Northern New York have led Eric to believe that the owls are heading back home!

This Ain’t the Midwest…

Switchgrass seeds

New Jersey isn’t a corn belt state and probably isn’t what you picture when you think “prairie.”  Fair enough.  But New Jersey is an incredible medley of ecosystems, and for the past five years we’ve been working to make sure that native grasslands remain in the mix. 

Switchgrass, big bluestem, and other native warm-season grasses provide excellent habitat for ground-nesting birds like the threatened bobolink and grasshopper sparrow (which is why we like them).  But they have many other uses, too, such as livestock forage, mulch, and even bio-energy (which is why farmers like them). 

Planting native grasses

More and more NJ farms are incorporating warm-season grasses and bird-friendly practices.  Pat Hilton just converted eighteen acres of her Readington Township farm to native grasses and is delaying the hay harvest on another thirty acres.  This will allow ground-nesting birds to fledge their young before the grass is cut. 

Pat’s rolling farm – call it “midwest-reminiscent” – is highly suitable for grassland wildlife and has already attracted eastern meadowlarks, kestrels, grasshopper sparrows, and northern harriers.

After another busy restoration season, we’re delighted to watch as the summer sun brings these grassland ecosystems to life.
