The White Red-tailed Hawk of Watnong Mtn.; Woody Guthrie and Greystone – Dec. 9, 2018

Watnong Mountain’s White (leucistic) Red-tailed Hawk is back for another winter, roosting along Old Dover Road in Parsippany-Troy Hills, just around the corner from Greystone Park Psychiatric Hospital. This Red-tailed Hawk is hard to miss after the leaves have dropped. Look for a white mass among the brown and gray tones in the woods edge while cruising along Old Dover Road.

2018-19 represents the fifth year, at least, that this hawk has used the base of Watnong Mountain as a roost. It was last seen in the spring on May 4, 2018, soaring with an apparent female before reappearing in November. Sightings of the hawk during the summer months are undocumented and simply unknown.

One can fantasize that this raptor embodies the spirit of Woody Guthrie, soaring over the area where he was hospitalized at Greystone Park from 1953-58 due to Huntington’s Disease. For those unfamiliar with Woody Guthrie: look him up, study his work, appreciate how we are all beneficiaries of his legacy, and be grateful he existed for the short time that he did.

Woody’s family, including his son Arlo, paid weekly visits to him at Greystone. A Minnesota folksinger named Bob Dylan visited Woody at Greystone as did Joan Baez, Phil Ochs, and many other troubadours of a new and engaged generation, receiving the torch of social consciousness through music passed to them from the master.

Woody resided in what he called Wardy Forty in the Kirkbride Building at Greystone. Unfortunately, this magnificent building, albeit in major disrepair, was demolished in October 2015 despite a passionate grassroots appeal for its survival. Those holding the pursestrings said it was not economically feasible to save it.

And so, along with much of the original Greystone Park grounds, another piece of history is laid to waste and replaced by a park with soccer and other playing fields and (gasp) two outdoor hockey rinks this observer has never seen used as well as field habitat desecrated by an unnecessary waste of asphalt named “Gov. Chris Christie Way”. Enough said.

Evening Grosbeaks, Vesper Sparrow, Boonton CBC – Dec. 1, 2018

Evening Grosbeak, Scherman Hoffman Sanctuary, Bernardsville, Somerset Co., NJ, Dec. 1, 2018 (Photo by Jonathan Klizas)

(Click on the photo for a larger image.)

Three female Evening Grosbeaks were the featured guests today at the feeding station of New Jersey Audubon’s Scherman Hoffman Sanctuary in Bernardsville. When the birds arrived, Susan Garretson-Friedman spread the word via various media outlets so that other people were able to watch the birds feed, preen, fly around, perch, call, etc.

Entering a query for Evening Grosbeaks in the eBird Species Map will display other reports from New Jersey in this season of winter finches.

The Evening Grosbeaks visiting New Jersey this season, are most likely of Type 3, the eastern population. Five different sub-species of Evening Grosbeaks are thought to exist. Here is a link describing the different sub-species’ vocalizations from the Earbirding website:
Evening Grosbeak Call Types.

Following is a map showing the range of the five sub-species of Evening Grosbeak, created by Kei Sochi. See Birding, November 2012, pp. 34–40, for full details.

Here is a size comparison between an Evening Grosbeak on the left and an American Goldfinch on the right. Both species are in the Fringillidae family. (Click on the photos for larger images.)

The Orange-crowned Warbler of Troy Meadows; Bob Perkins; other news – Nov. 3, 2018

Orange-crowned Warbler, Troy Meadows, Morris Co., NJ, Oct. 4, 2018 (photo by Warren Van Varick)

(Click on the photo for a larger image)

An Orange-crowned Warbler has been captured in beautiful photographs by Warren Van Varick on Oct. 4 and Dave Blinder on Oct. 23. Both sightings were found near the same area of Patriots Path at the southern end of Troy Meadows, accessed near the power and gas lines along South Beverwyck Rd. The Orange-crowned Warbler was usually seen along Patriots Path between the gravel parking lot and the gas line (see the South Beverwyck Road entry on the Troy Meadows map). Roger Johnson saw the bird in a similar area on October 10.

Orange-crowned Warbler, Troy Meadows, Morris Co., NJ, Oct. 23, 2018 (photo by Dave Blinder)

This writer saw it on the afternoon of October 25 after Warren photographed an Orange-crowned Warbler (OCWA) along the power-line in the morning. An OCWA was seen in the same area on Oct. 28 and Nov. 1 by Alex Bernzweig and Rob Fanning respectively.

Orange-crowned Warbler sightings in the Morris area are annual in autumn but not common. Are these coincidental sightings of different Orange-crowned Warblers by numerous people in a similar location? Or the same individual liking a certain area and hanging around for a month? The latter idea is reasonable although long staying Orange-crowned Warblers are rare in the Morris area. Cape May and points south are more likely.


Commemorative Ceremony for Robert L. Perkins, founder of Wildlife Preserves, Inc.

Perkins plaque, Troy Meadows, Oct. 27, 2018

You may not be familiar with the name, but Bob Perkins (1927-2017) is the reason we have Troy Meadows in Morris Co. and Great Piece Meadows in Essex and Morris Counties. On October 27, 2018, Wildlife Preserves hosted a ceremony commemorating a memorial plaque in honor of Bob Perkins at Troy Meadows. Dave Blinder wrote a blog post about the event. You can read that here. To find out more about this forward-thinking conservationist, read the interview conducted by An American River author Mary Bruno, here.

Bird migration as September ends – Sep. 30, 2018

Southbound bird migration is transitioning into the season of sparrows, finches, and short distance migrants. The past two days saw favorable conditions for birds on the move. View overnight migration radar maps at Cornell’s BirdCast web site, here.

A Connecticut Warbler was seen at Troy Meadows this morning along Patriots Path near the parking area accessed from South Beverwyck Rd. Five Lincoln’s Sparrows were scattered in the southern part of the meadows.

The previous week saw activity at North Branch Park, Bridgewater. The highlight was a Glossy Ibis (F. Durso) which remained throughout Friday, Sep. 28. Also visiting the flooded fields of the park that day were a White-rumped Sandpiper (D. Bernstein), a Blue-winged Teal and the continuing Pectoral, Semipalmated, and Least Sandpipers, and Lesser Yellowlegs.

September Birds, Autumnal Equinox – Sep. 22, 2018

Red-headed Woodpecker, Troy Meadows, Morris Co., NJ, Sep. 22, 2018 (photo by Jonathan Klizas)

(Click on the photo for a larger image.)

At least six Red-headed Woodpeckers are in the snag forest of Troy Meadows. This is accessed via the relatively new green trail north of Troy Brook. A deer exclosure, still under construction, restricts access to the snags but the woodpeckers are viewable if one walks close to the fence.

As of today, Flickers, Red-bellied, Red-headed, Hairy, and Downy Woodpeckers were all utilizing the numerous dead trees. This is a traditional wintering location for numerous Red-headed Woodpeckers. 2018-19 may bring a healthy number of Red-headed Woodpeckers to Troy Meadows. We are due for one of the cyclical irruptions of Red-headed Woodpeckers in Morris County.

1,129 Broad-winged Hawks were tallied today at the Wildcat Ridge Hawkwatch in Rockaway Township. Read the report here. Early reports from around the north New Jersey area echo similar results.

Connecticut Warblers are reported from three locations in Morris and Somerset Counties so far this month.

Dark-eyed Junco, Chimney Rock, NJ, Sep. 16, 2018 (photo by Jeff Ellerbusch)

New Jersey’s first Dark-eyed Junco of the season was found on the early date of Sept. 16 at Chimney Rock (J. Ellerbusch). This was repeated at The Rock on Sept. 19. Along with a Garret Mountain report from that same date, these remain the only reports of Dark-eyed Junco in the entire state of New Jersey so far this fall migration season.


Red-breasted Nuthatches and Purple Finches are widely reported recently. The forecast is for a winter finch irruption this year. Read Ron Pittaway’s annual Winter Finch Forecast here.


The Autumnal Equinox occurs at 9:54 PM eastern time, September 22, 2018.

Cory’s Shearwater in Madison (Aug. 1, not since) – Aug. 4, 2018

You read the title of this post correctly.

Robert Blair of The Raptor Trust informed mocosocoBirds a short time ago that on August 1, 2018: “a bird was left in our admit office that was found on Lorraine Ave. at the Route 24 overpass in Madison (Morris County). The bird turned out to be a Cory’s Shearwater. The bird was found on the side of the road and survived the night. It was transferred to Toms River Avian Care for further rehab and hopefully release.”

Amazing! And one more reason (not that any more are needed) to help support The Raptor Trust.

Birds at Boonton Reservoir – July 15, 2018

This is a quick note to document the number of birds seen at Boonton Reservoir this afternoon.

24 Great Egrets were all around the island which is by far, the most recorded at this location. The previous high total was 10.

49 Great Blue Herons were on the island and on the east shore of the reservoir. Most appear to be juveniles. 51 were tallied here on July 8.

382 Double-crested Cormorants were counted and it is quite possible 50+ were inadvertently left out of the total.

2 juvenile Black-crowned Night-Herons were seen on the north shore of the island.

Ring-billed Gulls are returning with approximately 70 reported today, the highest total since the middle of March.

Up to four Cliff Swallows were seen at one time. These are the nesting birds under the Route 202 bridge.

Cliff Swallows; Elegy for a Mute Swan – July 14, 2018

Cliff Swallow, Hillsborough Twp., NJ, June 22, 2018 (photo by Jeff Ellerbusch)

(Click on the photo for a larger image.)

During the 1980s, the center of Cliff Swallow breeding in New Jersey was at colonies on the Delaware River at Bull’s Island and Lambertville in Hunterdon County as well as several locations in Sussex and Warren Counties. The New Jersey Breeding Bird Atlas of the 1990s added scattered locations in northern New Jersey.

Since that time, Cliff Swallows have colonized bridges spanning the Raritan River from Middlesex to Somerset Counties. A new location was found this year at the Rt. 206 bridge viewable from Peters Brook Greenway, accessed from S. Bridge Street, Somerville.

Another newly discovered Cliff Swallow nesting site is the east bridge at Opie Road where 4 adults were seen flying to and from the bridge on June 22 (Jeff Ellerbusch).

The I-287 bridges over the Raritan may still host Cliff Swallow colonies. The Queens Bridge in South Bound Brook appears not to have any this year.

Cliff Swallow, Peters Brook Greenway, Somerset Co., NJ, June 29, 2018 (photo by Jonathan Klizas)

In Morris County, the Boonton Reservoir colony remains small but stable.

Another nesting site in Morris County is at Two Bridges in Lincoln Park (and Wayne and Fairfield). Cliff Swallows were reported sporadically from here in recent years. The swallows are apparently nesting under the Morris/Essex bridge as are the many Barn Swallows.

For those so inclined, Cliff Swallow can be listed for three counties at Two Bridges as this point is the convergence of Morris, Passaic, and Essex Counties.

Two Bridges, Lincoln Park, NJ, July 14, 2018 (photo by Jonathan Klizas)

Two Bridges can be a productive waterfowl spot in winter. The Pompton River empties into the Passaic River at this location. The current keeps the water open when other bodies of water are frozen.

In memoriam: The Mute Swan of Kitchell Pond

Mute Swan at Loantaka Brook Reservation, Morris Co., NJ, Apr. 1, 2015 (photo by Chuck Hantis)

Years ago, two Mute Swans inhabited Kitchell Pond (or Lake, if you prefer) at Loantaka Brook Reservation. Approximately ten years ago, one of the swans was killed. The story this writer heard was that a family let their dog into the pond and it attacked one swan, mortally wounding it.

The lone remaining Mute Swan continued through this decade, a regular and familiar presence at the lake year-round (Kitchell Pond is one of the few bodies of water in the Morristown area that resists freezing as long as it can in the winter ).

This year, the story mocosocoBirds heard is that the swan became entangled in fishing line for a lengthy time, became weak and was in rough shape by the time The Raptor Trust was notified and took it in for rehabilitation. The Trust did the best they could, but the swan took a turn for the worse and was humanely euthanized to end its suffering.

The White Red-tailed Hawk of Watnong Mountain – May. 4, 2018

Leucistic Red-tailed Hawk, Morris Co., NJ, Apri. 8, 2018 (photo by Jonathan Klizas)

(Click on the photo for a larger image.)

The first time this writer saw the above white raptor was approximately January 2014 on Old Dover Road, Parsippany-Troy Hills, maybe sooner. Yes, I did a double-take, stopped the car and watched as the hawk flew to another tree, ascertaining the bird was not a hallucination. More reports began trickling in regarding the same hawk.

Years have passed and allegedly the same leucistic Red-tailed Hawk still inhabits the same woods edge at the base of Watnong Mountain, right around the corner from Greystone Psychiatric Hospital.

What has noticeably changed is that the hawk now appears to be completely white, whereas this observer remembers some gray blotches on the wings and body and red and gray streaks in the tail.

Leucistic Red-tailed Hawk, Morris Co., NJ, Apri. 8, 2018 (photo by Jonathan Klizas)

Based on it’s smaller size, the hawk is probably a male. It creates quite a stirring sight especially once the leaves are off the trees. It can be seen all seasons along Old Dover Road.

Mating is a possibility as the Great White Hawk was seen soaring with an alleged female late this afternoon.

Red-tailed Hawks, Watnong Mtn., Morris Co., NJ, May 4, 2018 (photo by Jonathan Klizas)

Watnong Mountain rises to approximately 965 feet. The eastern side of the mountain is developed with apartments and housing developments. The western and southern side is mostly untouched except for a power line, water tower, water tank, and a few other odds and ends. Mountain Way crosses the mountain.

A popular disk golf course accessed from Old Dover Road is near a pond, called a reservoir on maps, but this activity is relatively benign and birds are in the area, nonetheless. A trailhead is at a parking lot/playground on Mountain Way with various trails covering the mountain.

Watnong Mountain is not a birding destination to go out of your way to visit. It is one of the many locations this website is fond of promoting as a local area worthy of protecting and preserving.

Here is a photo display of some recent birds at Watnong Mountain.

Yellow-throated Warbler Hybrid – Apr. 22, 2018

Yellow-throated Warbler is an uncommon migrant in Morris and Somerset Counties. The past two days saw an unusual number of reports in the area. In these two counties, Yellow-throated Warbler reports totaling greater than zero is unusual.

Yesterday at Lord Stirling Park, Bernards Township, a Yellow-throated Warbler was observed closely and well-described by Ben Barkley. That is interesting enough in itself.

Today, April 22, a different Yellow-throated Warbler was viewed in the afternoon and photographed by Simon Lane and earlier by Tom Smith which show a possible hybrid between a Yellow-throated Warbler and a Yellow-rumped Warbler.

As always, click on the photos for a larger image.

Below is a photo of a classic Yellow-throated Warbler at Colonial Park, Franklin Twp. in 2014. Many of you may remember this individual. Note the solid yellow neck and upper breast and the white abdomen.

Below is the Lord Stirling bird today with a necklace where some yellow should be.

Yellow-throated Warbler Hybrid, Lord Stirling Park, Apr. 22, 2018 (photo by Tom Smith)

Thickening the plot, note the faint yellow rump patch. Yellow-throated Warblers do not have yellow rump patches.

Yellow-throated Warbler Hybrid, Lord Stirling Park, Apr. 22, 2018 (photo by Tom Smith)

Putting these characteristics together equals a possible, if not probable, Yellow-throated Warbler and Yellow-rumped Warbler hybrid.

mocosocoBirds will attempt to get more information about this hybrid combination.
