The breeding season started off well enough for the peregrine family that star on our Falcon Cam in Jersey City this year. Four eggs were laid, three sisters hatched, were banded and were growing up high atop the skyscraper at 101 Hudson Street. Thousands of viewers enjoyed seeing them flapping and jumping, strengthening their flight muscles for their first flight to fledge from the nest.

Peregrine Falcon Bandings in Jersey City and Union County: The Importance of Banding Chicks
Story by Alison Levine
Two sets of peregrine falcon chicks were recently banded high atop buildings in Elizabeth, Union County, and Jersey City. Biologists from Conserve Wildlife Foundation (CWF) and the New Jersey Department of Environmental Protection’s Endangered and Nongame Species Program (ENSP) checked the health and measurements of the falcons, while also placing both United States Geological Service bird bands and state auxiliary bands so the birds can be identified in the future.
NJTV and TAPintoUnion captured the banding in Union County, while News 12 New Jersey and CBS-2 covered the Jersey City banding.

By Ben Wurst, CWF Habitat Restoration Manager
Ospreys have made great progress toward recovery in New Jersey, rebounding from a low of 50 nests in 1974 to 589 active nests in 2018. This progress should be celebrated, and victory can and should be declared, as The Press of Atlantic city suggested in their March 1 editorial “Maybe it’s time NJ declares victory in restoration of ospreys.”
But as a biologist who has studied ospreys for many years I also know that declaring victory doesn’t just mean we should walk away and abandon them.

By Ben Wurst
This is a project that we’ve dreamed about for some time. As you may know, much of our work with ospreys has been centered around Barnegat Bay, where the population has grown from around 60 pairs to over 140 nesting pairs over the past decade. This new camera will help us raise awareness for protecting this important indicator species in the Barnegat Bay watershed, who have direct implications for the health of our coastal environment.

CWF is celebrating International Migratory Bird Day all Week Long
by Lindsay McNamara, Communications Manager
CWF’s blog on the American kestrel is the fifth in a series of five to be posted this week in celebration of International Migratory Bird Day (IMBD). IMBD 2016 is Saturday, May 14. This #birdyear, we are honoring 100 years of the Migratory Bird Treaty. This landmark treat has protected nearly all migratory bird species in the U.S. and Canada for the last century.
In New Jersey, catching a glimpse of an American kestrel is a rare treat! These beautiful, colorful birds of prey are about the size of a mourning dove — they are the smallest falcon in North America. Kestrels are one of two falcon species that nest in New Jersey.
American kestrels are opportunistic hunters, feeding on a number of different animals like grasshoppers, lizards, mice, snakes and small birds. Unlike peregrine falcons, kestrels don’t use speed to kill their prey. They perch to see their target and then use a stationary, hovering flight that allows them to dive down short distances to capture their prey. The eyespots of a kestrel make it appear to be “looking” up at its aerial predators, like Cooper’s hawks, causing the predators to move on to find a less “alert-looking” target. The eyespots give kestrels the opportunity to focus on hunting for prey beneath them.
Kestrels also hide surplus prey in grass clumps, tree roots, bushes, fence posts, tree limbs, and cavities, to save the food for lean times or to hide it from potential thieves!
Kestrels utilize these hunting tactics in open, grassy habitats — especially ones with cavities for nesting and perches for hunting. Kestrels can be seen hovering in grasslands, pastures and parklands or perched along the road on telephone lines.
Kestrels can be found in both North and South America, from Alaska and Canada in the north to Argentina in the south. During winter in North America, they will migrate southward from the northernmost portion of their range. They live year-round within New Jersey.
Although the American kestrel is widespread, meaning they live year round throughout much of the United States, the northeastern kestrel population is declining. Today, the kestrel is listed as a threatened species in New Jersey.
The decline of kestrels in New Jersey is likely due to destruction of grasslands from development. Nesting cavities are also being lost. As humans clean up fields, we remove trees with nest cavities that kestrels use. Kestrels are secondary cavity nesters. They don’t make their own cavity but use existing natural or man-made cavities.
Since kestrels nest in buildings and other man-made structures, nest box programs are an effective way to help grow the number of kestrels in areas where nest sites are limited.
Conserve Wildlife Foundation of New Jersey, in partnership with the Endangered and Nongame Species Program implemented a nest box installation and monitoring program in 2006. Nest boxes have been placed in areas of habitat determined to be suitable for the birds of prey. The boxes are monitored by biologists during the breeding season. Because kestrels reuse nest sites, particularly if they have successfully raised young, we focus on boxes that have been successful at least once since 2006.
The nest box program in New Jersey appears to be successful; we are adding to the population. Since 2006, we have banded over 300 fledglings. You can help too! Next time you see an American kestrel in the Garden State, be sure to submit a Rare Species Sighting form.

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!
Photos from the Field: Peregrine Falcon Nestbox Installation in Trenton
Meeting our goals…we can only hope!
by Ben Wurst, Habitat Program Manager
In 1993-94 six young peregrine falcons were released at 20 West State Street (Mary G. Roebling Building) in Trenton to help bolster the population of urban nesting falcons in the area. Currently the closest nest is 20 miles away at the Tacony-Palmyra Bridge (where they also have a camera at the nest). Twenty years later and we may finally get some nesting falcons in Trenton! It all started when Jean Bickal, a worker in the building, noticed a falcon that often perched on the building ledges. From there Kathy Clark, a Zoologist with New Jersey Division of Fish & Wildlife made a site visit and took measurements to see if we could fit a nestbox (dog igloo) out a window on the 10th floor, which also had a roof on it. It appeared one would fit so we setup a date to install the new nestbox.
Cities and urban areas actually provide suitable habitat for falcons. Urban areas usually have lots of ledges under bridges or on buildings for them to nest, and abundant prey, in the form of pigeons and other songbirds. In New Jersey we have three other pairs that nest on buildings in Jersey City, Elizabeth, and Atlantic City, plus pairs that nest on the Tacony-Palmyra, Walt Whitman, Betsy Ross, and Burlington-Bristol Bridges.
On February 5th we helped install a new nestbox on top of a roof at 20 W. State St. We’re hoping that the falcon seen that day will find a mate and use the nestbox to raise young. Fingers crossed that we get some good news soon!
