Nelson’s Sparrow in Parsippany – Oct. 3, 2020

Nelson’s Sparrow, Parsippany, NJ, Oct. 3, 2020 (photo by Steve Kolb)

Late in the day on Saturday, October 3, 2020, Steve Kolb was across from the Hyatt Hotel near the intersection of Jefferson and Smith Roads in Parsippany. This is the area of the eBird hotspot, Jefferson Rd. Pond. A black morph of the Eastern Gray Squirrel caught Steve’s attention and he attempted to get a photograph of it.

The previous night’s heavy migration dumped an impressive bounty of birds in the Morris area. As Steve was trying for a squirrel photo, one particular bird piqued Steve’s curiosity and he fired off a number of photos of the Ammospiza species he was seeing.

By late Sunday morning, mocosocoBirds was made aware of the find. A few people looked but the Nelson’s Sparrow was not relocated.

This is the first documented Nelson’s Sparrow for Morris County that mocosocoBirds is aware of. It already appears on the county list but without annotation.

Steve’s photos are stunning. Take a look at his Flickr page, here.

Red Phalarope at Lake Parsippany; other records of interest – Sep. 26, 2020

Red Phalarope, Lake Parsippany, Morris Co., NJ, Sept. 26, 2020 (photo by Jonathan Klizas)

Lake Parsippany does not qualify as a pelagic destination but for reasons best reserved for the species themselves to divulge, a Red Phalarope, one of the most ocean-faring of shorebird species, spent the day at the southern end of the lake, viewed by many observers.

Separating the three phalarope species (Red, Red-necked, and Wilson’s) can be a daunting task in fall migration. Credit goes to Sean Ondich for finding and initially identifying the bird and to Rob Fanning for broadcasting the finding on the local rare bird text alerts.

Jeff Ellerbusch describes this particular individual as a “hatch-year Red Phalarope pretty far along into first pre-basic molt.” The phalarope’s identification was in question for a while this afternoon based on in-person observation and photo study as the bird showed conflicting characteristics of both Red and Red-necked Phalaropes.

In the end, Red Phalarope won out over Red-necked. Jeff heard a diagnostic high-pitched call which helped to clinch the identification. Also, Red Phalarope juveniles are further along in their molt cycle than Red-necked Phalaropes at this time of the year.

This is a historic sighting. As far as is known, this is the first record of a Red Phalarope in Morris County since September 1, 1990, when one was located at Boonton Reservoir by two giants in the history of New Jersey birding, Rich Kane and Tom Halliwell. That is thirty years and twenty-five days ago. Tom also has the only other known Red Phalarope record for Morris County from Lake Musconetcong on August 12, 1982.

American Golden-Plover in Morris County

Another sighting that has historic value for Morris County, is the American Golden-Plover found and photographed by Clint Robinson on September 21 at Freund Park, Roxbury Township. This is also known as Horseshoe Lake and is the trailhead for the West Morris Greenway. This is the first known record for this species in Morris County since David Harrison found one at the same location on September 28, 1989.

July Record of White-crowned Sparrow in New Jersey

Interesting rarities have appeared in New Jersey during the past few months dominating the state’s birding attention.

A local Somerset County sighting flew under the radar on July 24. Doryce Wheeler photographed a White-crowned Sparrow in her Bridgewater yard. The significance of this? There are no known records of White-crowned Sparrow in New Jersey for July…or August. Even June records are rare. Late September is the earliest this species arrives in the state. Quite a remarkable find in this unforgettable year of 2020.

Mourning Warbler Gallery – May 28, 2020

Mourning Warbler, Troy Meadows, NJ, May 26, 2020 (photo by Chuck Hantis)

(Click on the photo for a larger image.)

The secretive, skulking Mourning Warbler (Geothlypis philadelphia) is difficult to view during its spring migration from Central and South America on its journey to boreal breeding habitats and even more problematic in posing long enough to get a usable photograph.

Chuck Hantis captured this species in different poses on May 26, 2020, along Troy Meadows Road in the Troy Meadows Natural Area. Three of his photos are presented here. You can see more of Chuck’s extraordinary photographs at his Flickr site.

Mourning Warbler, Troy Meadows, NJ, May 26, 2020 (photo by Chuck Hantis)

In recent years, Troy Meadows Road has become as much of a reliable Mourning Warbler stopover as any. The time frame of its appearance since 2014 falls within May 19-31, occasionally with multiple individuals observed. A streak of ten consecutive days of sightings of this species occurred between May 22-31 in 2019.

Two Mourning Warblers were seen as recent as May 26, 2020. Ironically, a Vermilion Flycatcher was visiting another part of Troy Meadows on that same day viewed and photographed by a fortunate kayaker and not seen since (see that post here).

Vermilion Flycatcher at Troy Meadows, May 26, 2020

Vermilion Flycatcher, Troy Meadows, Morris Co., NJ, May 26, 2020 (photo by Ted O’Reilly)

(Click on the photo for a larger image at Cornell’s Macaulay Library)

The vestiges of prehistoric Lake Passaic are having a western flycatcher fest this season. First, a Say’s Phoebe spent a morning at the Great Swamp NWR on April 23. See that post here.

Yesterday, May 26, a Vermilion Flycatcher was seen and photographed by a kayaker at Troy Meadows. If accepted by the New Jersey Bird Records Committee, this represents the fifth state record for New Jersey and the first inland. The previous four records are Stone Harbor in May of 2002, Cape May October 2014, and two in 2019, September 25 in Cape May, and October 5 at Sandy Hook.

Ted O’Reilly was kayaking from the Passaic River to the Rockaway River and then the Whippany River crossing under I-280. He then made the right turn onto Troy Brook where the Vermilion Flycatcher was found. Fortunately, he was able to capture the moment with a camera.

Say’s Phoebe at Great Swamp NWR – April 23, 2020

Say’s Phoebe, Great Swamp NWR, Morris Co., NJ, Apr. 23, 2020 (photo by Chuck Hantis)

Thanks to Chuck Hantis for the above photo.

This morning, Marc Chelemer located, photographed, and spread the word that a Say’s Phoebe was in a field at the Great Swamp NWR. The Say’s Phoebe was in the field along Wood Duck Way near the refuge entrance on Lees Hill Road in Harding Township.

This represents the second Morris County record for this species. In fact, Morris and Somerset Counties have three of the past eight Say’s Phoebe’s records in New Jersey since 2011. The other five records are split between Cape May and Monmouth counties. That is nice geographical company to be associated with. This assumes the New Jersey Bird Records Committee accepts today’s record. Based on the many photos of today’s Say’s Phoebe, it looks like an easy decision for the committee to make.

Two previous spring records of Say’s Phoebe exist in the annals of accepted records of the New Jersey Bird Records Committee. The first was at Garret Mountain, April 16, 2003, and the last was in Cape May, April 30-May 1, 2009. Today, April 23, adds a third spring record splitting it right down the middle between the previous two April dates. Other than the spring records and a wintering Say’s Phoebe in 1956, all of the other New Jersey records are from September through November. Today’s record will make a total of 24 for the state.

Many observers were able to practice social distancing (enough of Covid-19 is written elsewhere) to see this western vagrant flycatching and perching on low vegetation. This, of course, adds a new species to the refuge list.

Say’s Phoebe, Great Swamp NWR, Morris Co., NJ, Apr. 23, 2020 (photo by Jonathan Klizas)

How many Say’s Phoebes have ventured to the northeast in 2020? There are two winter records from Vermont, of all places. An April 12 record from an airfield near Cleveland, Ohio, and two records from earlier in April near the west shore of Lake Michigan round out the other listings. Today’s Great Swamp record is it for the region as of today. Here is a Say’s Phoebe map for 2020 generated from eBird data today. The blue markers represent beyond thirty days from today and the red markers within thirty days.

Below is the typical range of this species courtesy of Cornel Laboratory of Ornithology’s Birds of the World.

Redheads, and the 2019 NJ Bald Eagle Report – Jan. 16, 2020

Redhead, Lake Parsippany, Morris Co., NJ, Jan. 16, 2020 (photo by Chuck Hantis)

(Click on the photo for a larger image.)

After a sparse waterfowl season, wintering ducks are starting to inhabit the lakes of the region. Chuck Hantis had at least eight Redheads and a pair of Canvasbacks at Lake Parsippany today. Two Redheads were there earlier in the week along with eight Northern Shovelers. Chuck’s beautiful Redhead photos appear on this page. His Flickr page is here and is worth a look.

The Emerald Ash Borer and Morris County Parks – Jan. 11, 2020

Fallen Ash Trees, Central Park of Morris Co., NJ, Jan. 11, 2020 (iPhone photo by Jonathan Klizas)

On December 22, a team of Boonton Christmas Bird Count (CBC) participants visited Central Park of Morris County, the former Greystone Park property. See a prior post about the park here. Nothing seemed out of the ordinary that day. The park looked like it had during the autumn.

Today, January 11, 2020, was this writer’s first visit to the park since the CBC. The first difference noticed was that most of the fields were mowed. The same cut took place the previous winter. The fields grow back. In fact, the stand of Common Milkweed was outstanding this past summer.

Walking along the path on the West Hanover Ave. side of the park revealed an entirely different scene. Dozens upon dozens of cut ash trees were piled up horizontally on the ground. The photo at the top of this page represents a small section of the ash tree removal procedure. It is the result of the Morris County Park Commissions’s Emerald Ash Borer Response Plan, the content of which can be read here.

Fallen Ash Trees, Central Park of Morris County, Parsippany-Troy Hills, NJ, Jan. 11, 2020 (photo by Jonathan Klizas)

According to the county park website, Morris County has the highest density of ash trees in the state of New Jersey. 12,000 trees are already tagged to date. Trees in high use areas will be removed. In select locations, the Morris County Park Commission is utilizing trunk injections of insecticides to protect select ash trees.

The county park web site gives a sense of the Emerald Ash Borer’s destruction: it has killed hundreds of millions of ash trees in North America and is considered to be the most destructive and expensive insect ever to invade the United States.

It seems appropriate to show some woodpecker photos from today. The Yellow-bellied Sapsucker and Downy Woodpecker are from Central Park of Morris County. The Hairy Woodpecker is from a different Central Park in Whippany. Click on the photos for a larger image.

The 84th Boonton Christmas Bird Count Report – 2019

The White Red-tailed Hawk of Watnong Mountain (photo by Chuck Hantis)

This is an updated version of the report. The compiler missed a checklist. The total species count is adjusted to 96, not 94 as originally stated.

The 84th annual Boonton Christmas Bird Count (CBC) occurred on Sunday, December 22, 2019, the first full day of winter. Temperatures at dawn were in the 18°F range but warmed up to 46° in the afternoon. 45 dedicated participants enjoyed a beautiful day outside.

The week leading up to the count was frigid. Most shallow lakes and ponds were frozen. Enough water remained open to get some waterfowl numbers at least. 

Recent rains caused local flooding but generally, conditions were as good as can be this time of year.

96 species were tallied along with two count week additions. This is better than the recent average and a testament to the wide coverage of the count circle.

2 count-week species, Common Loon, and Northern Goshawk are part of the record although not included in the actual totals for the count day (count-week is defined as three days prior to and three days after the actual count date).

The White Red-tailed Hawk of Watnong Mountain was tallied as he returns for a sixth year, at least, at his usual location along Old Dover Road near Greystone Psychiatric Hospital.

15,581 individual birds were tallied. This is an improvement over the past two years but still below the 21st century average of 25,566 and the eighty-four year average of 16,487.

Highlights for this year’s CBC are below.

  • For the first time since 2003, Eastern Screech-Owl, Great Horned Owl, Barred Owl, Long-eared Owl, and Northern Saw-whet Owl were tallied in the same year.
  • Red-bellied Woodpeckers rebounded from a recent dropoff and tallied 243 individuals, the second-highest total in the history of the Boonton CBC. This species was first reported as a count-week record in 1955. It did not get counted again until 1966 when it became an official number in the database and wasn’t reported again until 1972 when one was tallied. Numbers grew unabated since then, reaching a peak of 281 in 2001 before dropping off until this year.
  • Yellow-bellied Sapsuckers reached double-digits, 11, for the first time in count history. It was first reported in 1970. This shows the expanded range of this species. 2019 is the first year of confirmed nesting in Morris County, two actually, with possible 2018 nestings as well.
  • Woodpecker numbers, in general, are up from recent years.
  • Another new double-digit achiever and a relatively recent addition to the local avifauna, Common Raven reached their all-time high count of 12. Common Raven first appeared on the count in 2002.
  • 19 Winter Wrens is the second-highest count in Boonton CBC history with 23 in 1998 as the highest.
  • 1 House Wren represents the tenth occurrence of this species in the history of the Boonton CBC and the first since 2014.
  • 108 Carolina Wrens is the second time this number is reached and the second highest in count history with 120 in 2006 as the highest total.
  • All three mimic thrushes are represented with 3 Gray Catbirds, 2 Brown Thrashers, and 50 Northern Mockingbirds. 
  • A Palm Warbler was photographed at Hatfield Swamp and is only the third report of this species in the 21st century for the Boonton CBC.
  • Likewise, the third Common Yellowthroat record in the 21st century was had at Troy Meadows.
  • Sparrow numbers were impressive including, of all things, a record total of White-throated Sparrows, 1,591. The highest count prior to this was in 2001 with 1,554. Numbers fluctuate greatly in the interim period.
  • Swamp Sparrows are well-represented. A total of 183 is only the third time in eighty-four years that triple digits of this species were counted. The last two are 102 in 1975 and 207 in 1976.
  • 573 Song Sparrows is the highest total since 1,293 in 2001.
  • Field Sparrows had 55 which is the most since 63 in 2006 and a pleasant rise from the low numbers experienced in recent years.
  • Eastern Towhees had their second-highest total with 35. The 21st-century average is 7.0. The highest was 37 in, you may have guessed it, 2001. 2001 continues to popup with high counts because it is the all-time Boonton CBC maximum total individuals year with 62,336. It is not just because of ~20,000 Common Grackles and 17,000 European Starlings counted that year either. Eleven other species also broke the 1,000 count mark.

40 species were above their 21st Century average. Only 13 were above average in 2018. While this is a pleasant change from the downward trend in recent years, there remain troubling signs with many species and the overall total number of individuals.

Below is a graph of the total number of individuals on the Boonton CBC from 1936 through 2019. Keep in mind that total numbers did not consistently exceed 10,000 until the 1970s as the number of observers increased. A steady rise in totals is seen from the 1970s to 2001. After that, there is a decline in totals, except for the anomaly of 2013 which featured huge totals of Common Grackles and American Robins. 

In the following chart, the X-axis is the year and Y-axis the total amount.

Below is a list of species experiencing the sharpest declines based on 21st-century averages. Because of the icing of many bodies of water in 2019, waterfowl and waterbirds are kept out of this survey. Most of the species also appeared on the 2018 list of declining numbers:

    • Red-tailed Hawk – 25% off the average. The 21st-century pattern of overall decline continues.
    • Ring-billed and Herring Gulls were 62% and 77% off of their 21st-century averages, respectively.
    • Rock Pigeon – 192 in 2019 is the lowest total since counting for this species began in 1973, a continuing trend in recent years.
    • Mourning Dove – 33% off ave. 334 is the third-lowest total since 1988 with 254 in 2009 the lowest.
    • Am. Crows are down by 81%, a continuing trend,  while Fish Crows rose by 28%.
    • Black-capped Chickadee and Tufted Titmouse totals are not what they used to be. Both species continue their downward trend being 60% and 50% below average respectively. 155 Tufted Titmouse is the third-lowest total since 1969. For perspective, the average total of Tufted Titmouse from 1991-2001 was 518.
    • Am. Robins were down 91%, but totals of this species vary greatly from year to year.
    • No. Mockingbird rebounded this year slightly but are still down 41%.
    • Where have all the Starlings gone? 985 is 70% off average and the lowest total since 944 in 1970.
    • Dark-eyed Juncos are down by 43%. The third year in a row of totals under 1,000.
    • House Sparrow – down 54% continuing a recent decline. 2017 through 2019 represents the three lowest totals since 1971.
    • Many sparrow species had a positive rise in numbers this year, but American Tree Sparrows continue a downward trend. 2019’s 168 is much better than 2018’s 32 but a far cry from the glory days of the 1970s when 1,000 plus was common. 

The following species were seen by one party only. The species column is followed by the amount reported. The third column represents the percentage of occurrences in the 84-year history of the count:
