During the last week of February, egg hatching began in the Manasquan Reservoir Bald eagle’s nest. At present, we can’t see the chicks because they are too small. How do we know hatching occurred? It’s all about changes in the parent’s behavior. We observed the sitting adult moving around more, sitting higher in the nest, looking down often, and most importantly we observed feeding behaviors. The next big question is how many eaglets are there? We will have to wait and see. It will take another week or two before they are big enough to be seen easily.
The nest can be viewed from the Manasquan Reservoir Environmental Center. The Environmental Center hours are 10am-4:30pm, daily. If you view the nest outside, remember nesting eagles are very sensitive to human disturbance and could easily abandon a nest if disturbed. Please respect all protected areas. Posted 3/5/14
Full Moon Over Sandy Hook Bay
Last Friday, several people joined a Park System Naturalist for a full moon beach walk along Sandy Hook Bay at Bayshore Waterfront Park. It was Valentine’s Day and a beautiful evening to watch the moon rise over the bay. Winds were light, the sky was clear, and temperatures were relatively balmy in the lower 30s. It was a full “snow” moon, named by many prehistoric Native American people in the Northeast, since some of the heaviest snowstorms took place during this time of year.
If you missed this nighttime walk, please join us for Full Moon Meander (#INF42A) on Saturday, March 15th at Mt. Mitchll Scenic Overlook or Stargazing at the Seashore (#INP42A) on Saturday, April 26 at the Bayshore Waterfront Park. Online registration is available by clicking on the title of each program.

Recently, a small flock of about six to eight Snow Buntings have been showing up every morning near Sandy Hook Bay at the Bayshore Waterfront Park. The small birds have arrived from the high Arctic, where they have nested and raised 2 to 7 young during the summer. In the winter many Snow Buntings can be found around the bay resting and feeding on plant and grass seeds. The birds are getting ready for another long migration and busy breeding season up in the tundra starting in the spring. Posted 1/31/2014
These are exciting times at the Manasquan Reservoir! On January 21, our resident Bald Eagle pair began incubation. From now until hatching, one of the adults will almost always be seen on the nest. Eagles begin sitting immediately upon laying their first egg, but may produce up to two more eggs over the next few days. If more than one egg is produced, the eaglets will hatch in the order they were laid over several days. Generally, incubation requires about 35 days. This makes the approximate date of hatching during the week of February 24. The eagles' nest can be viewed from the Manasquan Reservoir Environmental Center, weather conditions permitting.

A Park Ranger recently discovered two Short-eared Owls hunting the open fields at Wolf Hill Recreation Area on Christmas Day. These Owls are regular winter visitors to New Jersey and are occasionally seen in Monmouth County. Short-eared Owls have a mottled brown appearance, are about 17 inches tall, weigh 7 to 16 ounces, and have a wing span of 25 to 40 inches. These grassland birds feed mainly on small mammals and may compete with the Barn Owl where their ranges over lap. They hunt during the day as well as at night. These Owls have a distinctive hunting technique, floating low over meadows and fields then diving on their prey. Their nests are mainly on the ground and their clutch can range from 1 to 11 eggs. Short-eared Owls are one the most widely distributed Owls in the word ranging across North America, South America, and Eurasia as well as many oceanic islands. Posted 01/03/14
One of our Park Rangers spotted a couple of Snowy Owls at Seven Presidents Oceanfront Park over the past several weeks. New Jersey is experiencing an unprecedented incursion of Snowy Owls this winter with more than 30 individuals reported along our shores. These beautiful birds stand about 28 inches tall, weigh around 4 to 5 pounds and have a 50 inch wing span. These are diurnal owls on their home range, the Arctic Tundra, where they feed on many small mammals but mainly on lemmings. They will also take small birds. The normal clutch size is usually between 3 to 4 but may be as many as 11 eggs. The adult males are almost all white while the adult females will be white with brown barring. Juvenile male and females will both exhibit the brown barring and can be difficult to distinguish. Posted 01/02/2014
This Marbled orb-weaver spider, found in Huber Woods Park, is part of the largest spider genera Araneidae. At 1500 species worldwide, the orb-weavers are at the top of the chart. Although scary looking, due to its large size (9 to 20mm) and extremely bright colors, this lady (females are larger than males) is quite harmless. Marbled orb-weavers are common inhabitants of trees, shrubs and tall weeds, but they prefer the grasses in moist, wooded settings and can frequently be found along the banks of streams. The spider gets its name from the beautiful marbling of its abdomen. Most common colors are orange, yellow, brown and purple and their hues. They build elaborate circular webs to catch their prey, but unlike most spiders they tend to hide under a leaf nearby instead of being displayed on their web. As seen in the picture these spider have 8 small eyes. Four are in the center of the head forming a box and a pair to the left and another pair to the right. These creatures are seen most frequently in late summer and fall. Next time you cross paths with one of them give them your best smile, they will not survive the cold New Jersey winter.

White-lined Sphinx Moth (Hyles lineata) Caterpillar Hartshorne Woods
There are several caterpillars considered "Horned Caterpillars" due to the large thorn like structure on its posterior. The White-lined Sphinx Moth caterpillar is a large, two inch long, colorful caterpillar that may appear intimidating but is actually quite harmless to humans. It is not considered an agricultural pest because the host plants are consider weeds by most people. They will feed on rose leaves but usually do not cause significant damage. The caterpillar will travel along the ground searching for a place to burrow and pupation will occur 2 to 4 inches below the surface. There are usually two broods of White-lined Sphinx Moths occurring between February and November. The November brood may overwinter in the pupate stage. Posted 10/16/13
Young box turtles are very secretive so it was a real treat to see this hatchling near the Manasquan Reservoir Environmental Center, Howell, in late August. Because they are so seldom seen this young, we know little about their habits. It is thought they spend most of their first years hidden beneath leaf litter eating insects. Box turtles reproduce very slowly, maturing by age 7 and producing 3-6 eggs once in
spring. Loss of habitat, people removing them from the wild, and slow reproductive rates contribute to the Eastern Box Turtle being listed as a Species of Concern in New Jersey.
Park Ranger Pat Becker spotted this Immature Brown Booby on the end of a jetty at Seven Presidents Oceanfront Park, Long Branch, on July 2.
If you take a walk on the trails at Huber Woods you will see clusters of this strange looking white plant. This is Indian Pipe, also known as Ghost Plant. Since it lacks color, Indian Pipe is one of the easiest wild plants to identify. It grows from June to September reaching a size of four to ten inches tall. The Indian Pipe prefers shady woods with rich soil and decaying plant matter. It blooms with small waxy flowers that droop and is a favorite food source for small bumble bees. The plant turns black when it gets old.
June marks the peak of the spawning season for the Bluegill sunfish. While at Shark River Park stop by the lake and check out the numerous fish nests near the shallow edge of the water. They are the result of the very hard working male bluegill. Each year they claim a territory to build their nest. Using their tail they scoop out a six to twelve inches in diameter spawning site in the gravel or sand, where they will wait for a female to arrive and deposit eggs. After the eggs are deposited the male stays and guards the nest from any intruders. In addition to being a watch dog, he is constantly using his tail to fan out the silt from covering the little, fragile eggs.
Seal Released Off Monmouth County Coastline
Recently, an adult 600-pound plus Grey Seal was released back into the Atlantic Ocean at Sandy Hook. The seal was found sick and mal-nourished in February 2013 near Seaside Park. After several months of care and treatment from staff at the Marine Mammal Stranding Center in Brigantine, NJ, the seal was healthy enough to send back into the wild to be free. The seal was released at Sandy Hook because of its location &S211; it&S217;s the northern most spot along the Jersey Shore and nearest to New England and the Canadian Maritime provinces where the western Atlantic population of Grey Seals often gathers to breed, feed, and haul out to relax during the summer.
The trilling call of the male Northern Gray Tree Frog can be heard on mild, humid nights from late April to August when the temperature rises above 60 F. Tadpole development is quite rapid and the bright-green juvenile frogs appear at the edges of their birth pond in mid-July. The almost identical looking Southern Gray Tree Frog is endangered due to habitat loss. The Southern Gray has a quicker, shorter, and higher pitched trill. Generally the Southern Tree Frog is not found in Monmouth County.
This Barred Owl was photographed in Hartshorne Woods as it flew out to investigate a man washing his car. The Barred Owl has become a rare sight in Monmouth County due to habitat encroachment and destruction. It was placed on the NJ Threatened Species List in 1979. The Barred Owl is known by many colloquial names including; Swamp Owl, Hooter Owl, Eight Hooter, Rain Owl, Wood Owl, and Striped Owl. It has well established populations in remote wetland areas and the highlands areas of the state.
The Barred Owl preys on small mammals but may include reptiles, amphibians, insects, or small birds in its diet. It has even been observed wading into water to catch fish. The Barred Owl's call has been described as, &S220;Who Cooks for You, Who cooks for you, allll&S221;, with &S221;hooah&S221; at the end. This Owl can often be heard calling on a cloudy day and is sometimes seen hunting during the day. The Barred Owl has brown eyes, a wing span of 42 inches, stands 21 inches high and weighs 1.6 pounds.

Spring is here and the sight of fern fiddleheads along the pond at Huber Woods Park is just another reassuring sign. These fiddleheads are the beginning of the Cinnamon Fern. Cinnamon Ferns are large ferns native to the Americas and Eastern Asia; their leaves grow up to six feet long and a foot wide. They grow in large clumps in moist woods, marshes, wet ditches, and stream banks. This fern often grows alongside other plants, such as Highbush Blueberry and Greenbrier. In early spring, new young leaves start to grow. They look like a skinny stem, which uncoils into a leaf. These young skinny structures are called "fiddleheads." Fiddleheads are eaten by white-tailed deer and other animals. Cinnamon Fern provides good cover and protection for small animals, such as squirrels, toads, birds, snakes, and insects.

Bullfrogs are found throughout the state in any permanent body of freshwater; however, they are not found in the core pine barrens due to areas naturally acidic water. They are considered an invasive species in New Jersey and have displaced our native Carpenter Frogs and the threatened Pine Barrens Treefrog.
Bullfrogs spend two years as tadpoles. Males and females can be distinguished by comparing the size of their eye relative to their eardrum (tympanum). In females, the eardrum is the same size of the eye, or smaller, and in the male the eardrum is much larger than the eye. The males call from around April through July with a bellowing jug-o-rum.

Bluebells Blooming at Historic Walnford, Upper Freehold
The bluebells are blooming at Historic Walnford, Upper Freehold! These colorful wildflowers can be found along the banks of Crosswicks Creek. Even better, there&S217;s a good chance that the flowers will be at their peak for the Bluebell Festival on Sunday, April 14th.
We are very excited to announce that we have two eaglets at the Manasquan Reservoir! Here are a few eaglet milestones:
- Hatching began March 4th.
- At 4 to 5 weeks eaglets can stand and feed themselves.
- By 6 weeks they are almost as large as their parents and they take their first flights around 10 to 13 weeks.
Come visit us at the environmental center to learn more about our eagles and other wildlife. Posted 4/9/13
Wood Frogs and Spring Peepers Calling
Spring is in the air and so are the calls of wood frogs and spring peepers. These amphibians begin
calling in mid-March, but wood frogs may call as early as February. Wood frogs breed only in vernal wetlands. These temporary wetlands form from spring rains and snow and are vital for several amphibian species. Spring peepers also call from vernal wetlands, but are not as particular and will use any body of freshwater to breed. The call of the wood frog is a duck-like quacking and the tiny spring peepers, as their name implies, loudly peep. You can discover more about Monmouth Counties' amphibians with our Nature Series brochure on Amphibians (PDF required). Posted 3/13/13
One of our Park System Naturalists spotted this Silver-haired bat hanging on the side of one of the out buildings in the Timolat Section of Huber Woods recently. The bat appeared to be in great condition and was taking advantage of the warmth of the buildings southern exposure. Silver-haired Bats can be quite common when migrating and will be found on the sides of buildings, railroad ties and fence posts. This bat is a tree bat and it usually does not roost in large colonies. It typically roosts under loose tree bark but will also use woodpecker holes and bird nests. The Silver-haired bat was not affected by the &S220;White-nose Syndrome&S221; fungus that has devastated cave bats. This year the NJ Bat Sanctuary has experienced an increase in calls regarding the Silver-haired bat and many of the reports are from Monmouth County. These are medium sized bats with a wing span of 11 to 13 inches and weighing .3 to .4 ounces.
Eagle Hatching has begun! Hatching was officially called March 4th. We'll be waiting to see how many heads pop up in a week or two. Check back here for more updates. Posted 3/5/13
This beautiful adult Cooper's Hawk was seen near the Environmental Center recently. Cooper's Hawks belong to a group of woodland hawks known as accipiters that specialize in hunting small birds.The Cooper's Hawk is crow sized and fits between the smaller, but similar, sharp-shinned hawk and larger northern goshawk. During the breeding season, Cooper's Hawk are found in upland, riparian or freshwater wetland forests. For several seasons, a pair had a nest at the reservoir. The Cooper's Hawk was recently reclassified from Threatened to Special Concern due to an increase in the breeding population. However, this good news must be tempered by the continued threat posed by the loss of the large, contiguous forests it needs for breeding and hunting. Posted: 1/30/13
On Saturday, January 26th the bald eagle pair at the Manasquan Reservoir began to incubate eggs. For the next 35 days, on average, one of the adults will always be sitting on the eggs until they hatch around March 1st. Check back for more updates, or visit the Manasquan Reservoir Environmental Center. Posted 1/30/13
White-Winged Crossbill and Red Crossbill
White-Winged Crossbills and Red Crossbills have recently been observed feeding in the Japanese Pines at Seven Presidents Oceanfront Park and in the pines at Thompson Park (White-winged). These finches breed in Canada usually only visiting NJ in the winter and not all that often. They have specialized bills for removing seeds from pine cones. The upper and lower mandibles actually overlap, side to side, enabling the bird to easily remove the seeds. Photo by Jeff Lee - Posted 01/25/13
Razorbills have been observed up and down the East Coast this year with many sightings as far south as Florida. Several Razorbills have been seen from the beach at Seven Presidents Oceanfront Park this month. These small pelagic birds have a wing span of 26&S221;, weigh about 1.5 pounds and are ocean dwellers. Razorbills venture onto land to breed along the cliffs and rocky islands of the northern most reaches of North America&S217;s east coast. However, about 65% to 70% of the world razorbill population breeds in Greenland. They mate for life and usually produce one chick per year. Razorbills feed on capelin (a type of smelt), sand lance, juvenile cod, sprats and herring. Most feeding takes place down to depths of 80 feet but they can dive as deep as 400ft.

A Western Grebe was reported off the beach at Seven Presidents Oceanfront Park this month. This species, though still rare in NJ, is beginning to be a yearly winter visitor to the Jersey Shore with sightings nearly every year since 2002. The dull yellow bill, dark face and long slender white neck are distinctive. Weighing in around 3.5 pounds and with a wing span of 24 inches, it is the largest Grebe in North America. This bird breeds in huge colonies on large lakes and marshes in the westen part of the US. They are known for a spectacular courtship dance that takes place in the open water.

The Pink-footed Goose is a rare visitor to NJ. This one was photographed in Mercer County during the Park System's last &S220;Winter Birding Expedition&S221; bus trip on January 9. It has since been seen at Assunpink Reservoir and other locations in Monmouth County. The Pink-foot breeds in Greenland / Icland and very seldom ventures to New Jersey. The state&S217;s first sighting was in March of 2007. The Pink-footed Goose population is on the rise largly due to increased protection from hunting on its wintering grounds. This Pink-footed Goose (left) is next to a Canada Goose. Photo by Jeff Lee -Posted 01/25/13
The Bald Eagles at the Manasquan Reservoir have been busy. They have recently built a new nest about 150 yards east of their old nesting location. Historically this eagle pair has begun their egg incubation during the first and second week of January. Eagle watchers at the Reservoir are anxiously awaiting the event. Winter is one of the best times to view the eagles at the Manasquan Reservoir located in Howell, NJ. Drop by the Environmental Center for all the up to date information. Posted 1/10/13
This medium sized, well camouflaged woodpecker is a transient in Monmouth County seen during the spring and fall migrations. Occasionally, some will stay over for the winter. This male was photographed this week at Huber Woods in a stand of spruce trees. The females have a white throat but otherwise they are very similar to the males. Sapsuckers do not actually suck the sap from trees but they lap it up with their tongues from the holes that they drill into the tree. The holes are generally drilled in parallel rows. Insects will take advantage of the sap oozing from the holes and the sapsucker will readily eat the insects that may become stuck in the sap. Hummingbirds have been observed taking advantage of the sapsuckers handiwork as well. There have been over a 1000 species of trees that the sapsuckers have drilled but they seem to prefer birches and maples. Posted 01/03/13
Northern Saw-whet Owl
One of our park rangers discovered this rarely seen winter visitor and one of our park naturalists was able to snap a picture of this shy creature. With a wing span of only 17 inches and a length of 8 inches, the Saw-whet Owl is slightly smaller than the Eastern Screech Owl but, at 2.8 oz., weighs less than half as much. These nocturnal birds feed almost entirely on small mammals with deer mice being the preferred prey, followed by shrews and voles. They will also eat small birds, frogs and insects. The Northern Saw-whet inhabits deciduous and coniferous forests and is a cavity nester. The owl's name comes from the "skiew" call that is made when alarmed. This noise has a resemblance to the whetting of a saw. Posted 01/04/13
