eBird Hotspot notice; Birds of West Morris Greenway, June 25, 2014

Yellow-crowned Night-Heron – Jefferson Rd. Pond is now an eBird Hotspot

The Parsippany Yellow-crowned Night-Heron (YCNH) of Jefferson Road Pond is seen either on branches near the pond or under the Jefferson Road bridge. Alan Boyd photographed the YCNH today. Some of his photos are here and here. Alan’s flickr photostream is here.

From Mike Ostrow:
“You never know what you’ll see out of this little corporate pond. The juve Yellow-crowned Night-Heron was in the water between the footbridge and road bridge. When I crossed over the road to look on the other side, a deer came out of thickets, from where I have no idea, crossed under the bridge in the water, and eventually came back. When I went back to the other side, it was clear the deer had flushed the heron out of its hiding area between the bridges and out onto the pond!”

Important note to eBirders: Jefferson Road Pond is now an eBird Hotspot. Please change your personal location to this Hotspot.

Here are the instructions in case you do not know how:

  1. From your eBird account, go to My eBird.
  2. Select Manage My Locations from the My Observations sidebar.
  3. Search for whatever-you-labeled-Jefferson-Road-Pond-as and select it. This will load the Edit Location page.
  4. Select Merge. You will see a red Hotspot marker for Jefferson Road Pond. Select that Hotspot. Select the Merge button and your checklists from that spot will now be associated with the Hotspot. Your personal location is removed.

This allows anyone to view ALL of the records out of the database for this location in one fell swoop. Please do this as soon as possible. The eBird range map for Jefferson Road Pond is currently a big mess and quickly growing into a bigger mess.

West Morris Greenway – North

The West Morris Greenway starts at Horseshoe Lake in Roxbury Township, goes south across Righter Road through an easement of the Morris County Municipal Utilities Authority’s (MCMUA’s) property, crosses Pleasant Hill Road in Randolph Twp. and continues, eventually joining the Black River WMA portion of the trail all the way to Pleasant Hill Road in Chester Twp. The northern, or Roxbury/Randolph, section was dedicated in June of 2012.

This post chronicles the northern section through the MCMUA easement. The trail is quite wide (auto road width) and covered with fine gravel. It is completely flat and bordered on both sides by an attractive bottomland deciduous woodland with numerous ferns and other understory plants. There are a few MCMUA dirt roads interrupting the woodland. There is a powerline cut at approximately .75 miles from Righter Road. It is a popular jogging and biking trail so going there early in the morning is best, but there is enough room for everyone.

Bird highlights include 2 singing Northern Waterthrushes (NOWA), one on the south side of the trail opposite the first dirt road on the north side; the second, past the power line near mile marker 4.5. Both NOWA were silent by 8:00 a.m. At least 1 Pine Warbler was trilling in the White Pine grove at the power line. Other species include a flyover Green Heron, Eastern Wood-Pewee, Great Crested Flycatcher, Yellow-throated Vireo, numerous Red-eyed Vireos, Blue-gray Gnatcatchers, Veerys, Wood Thrushes, Ovenbirds, American Redstart, Eastern Towhees, Field Sparrows, Scarlet Tanager, Indigo Bunting, and other typical species.

Night-Herons, June 24, 2014

The juvenile Yellow-crowned Night-Heron of Jefferson Road Pond continues today either under the Jefferson Road bridge or roosting on tree branches near the pond (m.obs.). Two adult Black-crowned Night-Herons are on the island as they have been all spring. A juvenile Black-crowned Night-Heron joined the party last evening (Chris Thomas) but has not been seen today, as far as is known.


4 Black-crowned Night-Herons, 3 adults and 1 juvenile, were seen around the pond today on the Somerset County side of Green Brook Park (Walter Blenderman). A Green Heron was also in attendance.

Blue Trail, Split Rock Reservoir, NJ, June 24, 2014 (photo by Jonathan Klizas)

A 5-mile trek on the east side of Split Rock Reservoir produced Yellow-billed Cuckoos, Pileated Woodpeckers, Eastern Wood-Pewees, Great Crested Flycatchers, Yellow-throated Vireo, Warbling Vireo and 22 Red-eyed Vireos, Common Raven, 20 Ovenbirds, 2 Louisiana Waterthrushes, Hooded Warbler, American Redstart, Yellow Warbler, Prairie Warblers, Scarlet Tanagers, Rose-breasted Grosbeak, Indigo Buntings, and other species typical of the Morris Highlands.

The route started at the parking lot near the dam (the road over the dam is closed indefinitely while being resurfaced and renovated) picked up the blue trail by the power-line cut, followed the trail up and over Buck Mountain (an especially lovely section) and hooked up with a woods road for the return trip. This is a route that reminds one how rugged and rocky Morris County can be.

Yellow-crowned Night-Heron in Parsippany, June 23, 2014

Yellow-crowned Night-Heron in Parsippany

(Click on the photo for a larger image.)

A juvenile Yellow-crowned Night-Heron (YCNH) was found under the Jefferson Road bridge at Jefferson Road Pond this afternoon by Julie Buechner. This is the second summer that YCNH is known to be at this location. One was found on September 9, 2013. It was soon joined by second YCNH, and later, a juvenile Black-crowned Night-Heron. They stayed at the pond into the first week of November.

At least two adult-like Black-crowned Night-Herons are currently using the island in the pond for a roost in 2014.

Where are the YCNHs coming from? It is not known for certain whether the 2013 YCNHs were present before September. Regarding 2014, isn’t it early for post breeding dispersal? Is it possible YCNHs are nesting locally in the corporate park? Why haven’t we seen adult YCNHs? There is more to come.

(The photo above may look like flash was employed but no artificial lighting was used. The YCNH was under a bridge. It was simply a Canon EOS 7D with a 400mm f/5.6 lens, 2500 ISO, 5.6 aperture and 1/200 of a second shutter speed.)


Other field notes

Lincoln Park Gravel Pits has 4 Great Blue Herons, 2 Great Egrets, 2 Green Herons, 7 Killdeer and an Osprey (J. Klizas).

From Bob Auster:
“I saw 5 Bobolink at Duke Farms, yesterday, June 22, 2014, around 1:30 PM. I initially saw 2 males in the field past Farm Barn Lane and then a flock of 5 flew from that field to the field behind Farm Barn Orientation Center.”

Common Gallinule; Indian Cliffs, June 22, 2014

Common Gallinule at Deerhaven Lake

Common Gallinule, Deerhaven Lake, NJ, June 22, 2014 (heavily cropped photo by Jonathan Klizas).

(Click on the photo for a larger image.)

On June 22, 2013, a hike and a bushwhack to the eastern side of Deerhaven Lake in Morris County produced a sighting of a Common Gallinule (see that post here).

On June 22, 2014, a hike and a bushwhack to the eastern side of Deerhaven Lake in Morris County produced a sighting of a Common Gallinule in exactly the same location as seen the previous year on exactly the same date. This is the only Common Gallinule recorded in eBird during 2014 for both Morris and Somerset counties. Either none were found in the Great Swamp NWR during the World Series of Birding or they have not been reported.

Deerhaven Lake is in both Jefferson and Rockaway Townships with most of it in Rockaway. It contains one of the most picturesque heronries in New Jersey or anywhere else. The nests are in the tops of towering old White Pine or Norway Spruce snags. Living Pines and Spruces along with the Green Pond Mountain escarpment provide the beautiful background. The lake with a beaver lodge, smaller snags, and a cattail swamp (and Phragmites, of course) add to the complete picture in the foreground. It is not a drive-up location but requires a 3 mile round-trip hike that is sometimes on an established trail (the Four Birds Trail) and often not. There were approximately 40 Great Blue Herons counted today with many juveniles in the nests.

Other species in the area and along the trails are typical of the Morris Highlands. A drake Hooded Merganser was snoozing at the lake. The many Wood Ducks present are currently in eclipse plumage. A Belted Kingfisher was working the water. Green Herons nest at the marshy end of the lake. Pied-billed Grebes were heard earlier in spring but not today. A Common Raven croaked overhead. They have nested on Green Pond Mountain in the past. Trumpeting Pileated Woodpeckers echo through the woodland. A pair of Great Crested Flycatchers sound like ten.

The juvenile bird below is Ovenbird-sized. It was seen again on the return trip in the company of an adult Ovenbird. Unless anyone has a different opinion it is labeled as an Ovenbird.

Indian Cliffs

Split Rock Reservoir from Indian Cliffs, Rockaway Twp., NJ, June 21, 2014 (photo by Jonathan Klizas)

Indian Cliffs is arguably one of the most scenic and spectacular locations in Morris County. An easy scramble up the glacially piled-on boulders on the blue trail brings one to a magnificent view of Split Rock Reservoir to the south and the New Jersey Highlands to the north and west. The stretch along the Four Birds Trail provides an excellent understory of Blueberry, Spicebush, Mountain Laurel, etc.

Starting from the Timberbrook parking lot (next to the entrance for the Winnebago Scout Reservation), go north either by the yellow-blazed trail or the dirt road. The Four Birds Trail (white blazes) intersects at approximately .8 miles. Go east for 1+ miles to the intersection with the blue trail. Take the blue trail past Misty Pond, cross over a woods road and continue on to Indian Cliffs. A New York-New Jersey Trail Conference map is a handy companion. Ovenbirds, Red-eyed Vireos, Great Crested Flycatchers, Eastern Wood-Pewees, Worm-eating Warblers, Scarlet Tanagers, Nuthatches, Chickadees, Titmice, Woodpecker species and more are the accompaniment along the way. Possibly anything can fly-by while standing atop Indian Cliffs.

Friday Bird Notes, June 20, 2014

The Summer Solstice occurs on Saturday, June 21 at 6:51 a.m. EDT (10:51 UTC).


Least Bittern at Troy Meadows

Troy Meadows, NJ, June 20, 2014 (photo by Jonathan Klizas)

The Susquehanna-Roseland Project rolled through northwest Morris County in 2013. Along with the 500 kilovolt transmission line upgrade, Troy Meadows also had it’s dilapidated wooden walkway replaced as a result of the project. People who birded Troy Meadows years ago, may have memories of the old walkway, and like myself, may have fallen through a rotten plank or two along the way.

The new boardwalk is constructed of recycled plastic. It is of a latticed design which allows drainage. It also allows the Phragmites to overwhelm the walkway as they can easily poke their stems through the grids of the surface as can be seen in the photo above. The walkway may appear to end at the wall of Phragmites but actually continues on – if you dare.

Early this morning, the current writer dared, trudging through the dew-covered vegetation and was rewarded with a fly-by Least Bittern. Elsewhere in Troy Meadows, a Pine Warbler was a surprise, singing and moving from one mature White Pine to another in the overgrown area known as the old homestead. Although they breed in Rockaway Township, this is not a typical species for the Parsippany area. Here is a recording: Pine Warbler, Troy Meadows, NJ, June 20, 2014

While walking at the edge of the marsh at the south end of Troy Meadows, a Wild Turkey hen and 5 poults were encountered.

From Mike Newlon:
This afternoon a pair of Bobolinks was at the Wagner Farm Parking lot on Mountain Ave in Warren Twp [Editor’s note. This is the property adjacent to Glenhurst Meadows]. The male spent much time singing from the fences of the two garden enclosures.

From Roger Johnson:
Went up to Snake Hill Rd., Rockaway Twp. – Lake Denmark Rd. is closed.
1 Worm-eating Warbler
1 Cerulean Warbler
8 American Redstarts
1 Louisiana Waterthrush
2 Acadian Flycatchers
Other expected species – the forest was rather quiet.

1 Great Egret was flying into Boonton Reservoir

Yet another Blue Grosbeak was found today in Somerset County. This one near the Opie Road/River Road area by the Branchburg/Hillsborough border (Frank Sencher, Jr.).


A Least Bittern was seen flying about this morning by the Friends Blind of the Wildlife Observation center of the Great Swamp NWR (Jeff Ellerbusch).

Cliff Swallow status; Bird Notes, June 17, 2014

Cliff Swallows

Cliff Swallow, Boonton Reservoir, NJ, June 17, 2014 (photo by Jonathan Klizas)

2014 is at least the fourth year that Cliff Swallows are nesting at a few locations in Morris and Somerset Counties. The Cliff Swallows at the I-287 Bridge at Easton Avenue, Franklin Township maxed out with 17 nests in late July of 2013 (Jeff Ellerbusch).Today, 2 Cliff Swallows were at one nest at that location. There is a possible second nest next to the first. This is quite a drop off from 2013. The other Somerset County location on Weston Canal Road is not surveyed yet in 2014.

The Cliff Swallow population at the Rt. 202 bridge at Boonton Reservoir is stable. 8 Cliff Swallows were seen at one time. All of the nests are on the underside of the bridge. Based on where the swallows were flying to, there at least 4 nests and probably more  – similar to the previous two years.


Although difficult to view with the foliage, 2 Black-crowned Night-Herons continue to roost on the island at Jefferson Road Pond in Parsippany.


Blue Grosbeak and Yellow-breasted Chat at South Branch WMA

The South Branch WMA lies mostly in Hunterdon County although the northeastern section of the WMA is in Hillsborough Township, Somerset County. The following report is from Frank Sencher, Jr.:”The South Branch WMA Yellow-breasted Chat is 165 feet from the Somerset border, you can easily hear it from the parking lot. The singing Blue Grosbeak was in Somerset County by 220 feet.”


2 Blue Grosbeaks continue near the community garden at Duke Farms in Hillsborough Twp. (eBirded by Vicki Schwartz).

Lost Lake, Flycatchers and a Cerulean Warbler, June 15, 2014

While peering into the backyard this afternoon: nesting status…confirmed!

Rockaway River WMA, Jefferson Township

Beaver lodge at Lost Lake, Jefferson Twp., NJ, June 15, 2014 (photo by Jonathan Klizas)

The Rockaway River Wildlife Management Area of the Farny Highlands encompasses 3,667 acres according to the state of New Jersey. It is adjacent to the eastern section of Mahlon Dickerson Reservation. The Beaver Brook Trail comes out of Mahlon Dickerson at Saffin Pond and travels the entire length of the WMA in a north-south direction. The trail is bisected by the Susquehanna-Roseland power line. The trail south of the power line was covered last weekend and is documented here.

The section of the Beaver Brook Trail north of the power line, including Lost Lake, was hiked today. One can bird the Rockaway River WMA, but one must hike it to do so. This is not convenience birding. The Rockaway River WMA is described in various online sources as rugged, mountain goat territory, grueling, etc.

Taking a slight shortcut, today’s trip started at Saffin Rock-Rill (see yesterday’s post). The two Least Flycatchers 0f Saffin Rock-Rill were singing this morning, by the way. The yellow trail, by way of the unblazed yellow-black trail, hooks up with a woods road which intersects with the white-blazed Beaver Brook Trail. The windy conditions this morning made it difficult to hear or it could be that this section doesn’t have the variety of bird life the southern section does.

The trail passes Lost Lake where two beaver lodges stand out in the middle of the water. One beaver was seen swimming into it’s home. The birding highlights were an Acadian Flycatcher, heard along the trail halfway between Lost Lake and the power line;  Least Flycatcher, heard in a lovely Mountain Laurel section of an unmarked woods road west of Lost Lake as a Broad-winged Hawk circled overhead; and further west on the same woods road on an up-slope was a singing Cerulean Warbler. Here is an audio recording. The Cerulean Warbler is faint but audible:

Gleanings from eBird

Two Blue Grosbeaks were “flying around the power lines” at Negri-Nepote Native Grassland Preserve (Chris Thomas).

An Eastern Meadowlark was: “In fields on NW side of Tilcon Lake, only present briefly – sang a few times, flew into tree, sang a few more times, flew off” (Tom Smith).

Birds of Mahlon Dickerson Reservation; other field notes, June 14, 2014

Mahlon Dickerson (1770-1853) Morris County native; New Jersey Governor and Senator.

Mahlon Dickerson (1770-1853) Morris County native; New Jersey Governor and Senator.

Morris County native, Mahlon Dickerson (1770–1853), was a New Jersey governor and senator, a Secretary of the Navy under Presidents Andrew Jackson and Martin van Buren, the elder brother of another New Jersey Governor, Philemon Dickerson, and is the namesake for the largest park in the Morris County Parks system.

Recording: Black-throated Blue Warbler, Mahlon Dickerson Reservation, June 14, 2014

3,200 acre Mahlon Dickerson Reservation lies in the northwest section of Jefferson Township and represents the North Country of Morris County.

Some of the most interesting and hard-to-find breeding species in the county are located in this park. The highlights of today’s birding hike in Mahlon Dickerson include Acadian Flycatcher, Least Flycatcher, Northern Waterthrush, and Black-throated Blue, Worm-eatingHooded, Cerulean and Canada Warblers. The complete eBird checklist is here.

Recording: Canada Warbler, Mahlon Dickerson Reservation, June 14, 2014

Two Acadian Flycatchers were found: one along the Ogden Mine Railroad Trail; the other along the Pine Swamp Trail (white blazes) accessed from Sparta Mountain Road. These are traditional locations. Other species in the Pine Swamp (actually a Rhododendron, Hemlock, Black Spruce swamp bordering on Sussex County) are Louisiana and Northern Waterthrush, and Black-throated Blue, Hooded and Canada Warblers. A Cerulean Warbler was singing along the Ogden Mine RR trail as well (a sound recording is here). Cerulean Warbler was reported from this same location on May 26.

Two Least Flycatchers were singing within 100 meters of each other on the yellow trail at Saffin Rock Rill at the southern end of Mahlon Dickerson Reservation.

Here is a recording of Least Flycatcher #1 (slower and more deliberate):

And here is Least Flycatcher #2 (faster and declamatory):

There are numerous trails and access points in Mahlon Dickerson Reservation, too many for one June morning.


Somerset County Summer Tanager in Nest

Jim Schlickenrieder found the female Summer Tanager sitting in a nest at Lord Stirling Park today. This represents the first known nesting attempt in Somerset County history. Obviously, birders are asked to enjoy the news and leave the birds alone.


Yellow-breasted Chat in Great Swamp NWR

The Yellow-breasted Chat at the northwest corner of the intersection of Pleasant Plains and White Bridge Roads continues today (m.obs.). The last known report of the Yellow-breasted Chat in Lord Stirling Park is June 8.


Northern Parula in Hillsborough Township

On Wednesday, June 11, a Northern Parula was heard near the Neshanic River (Frank Sencher, Jr.). A possible and a probable nesting record of Northern Parula is listed for Somerset County in the New Jersey Atlas of the 1990s. The Hillsborough record is the latest known date in Somerset County during the eBird era.

Birding week in review, June 13, 2014

A cold front is moving through Morris County as this is being written. Fog and rain have dominated the weather scene most of the week.

A Yellow-breasted Chat continues to vocalize at the corner of Pleasant Plains Road and White Bridge Road as of today (Chris Thomas). This bird has not been seen as far as is known but is singing its unmistakable repertoire.

A Prothontary Warbler and Acadian Flycatcher are both along the Lamington River on Black River Road south of Long Lane in Bedminster Township as of June 11 (Alan Boyd).

June 11 is also the most recent reported sighting of the Lord Stirling Park Summer Tanager at the north end of Lenape Meadow. The same date also saw Prothonotary Warblers and Black-billed Cuckoos (Jason Denesevich).

From Terry Carruthers, June 11:
“At least two male Bobolink are on territory at the Harding Fields [Frelinghuysen Fields – Ed.] on James St in Harding Twp. This is the third year that the birds have been seen here, with females present too in previous years.”

As most readers of this blog know by now, Len Soucy, the founder of The Raptor Trust in Millington, passed away on June 11. Chuck Hantis sent a link for a Martha Stewart video featuring Len and The Raptor Trust titled Raptor Trust Bird Sanctuary Visit. The link for that video is here. A warm tribute to Len is posted on the The Raptor Trust web site as well.
