Common Nighthawk, Olive-sided Flycatcher, Field Notes, Aug. 17, 2013

Common Nighthawk in Morristown

Common Nighthawks will begin migrating through our area during the next few weeks. A single Common Nighthawk flew over I-287 near South Street in Morristown at 7:00 p.m. this evening.

Olive-sided Flycatcher at Great Swamp NWR

The second Olive-sided Flycatcher (OSFL) of the day in Morris County was seen late today near the north gate of Pleasant Plains Rd., Great Swamp (Simon Lane). Another OSFL appeared in Rockaway in the morning and was one of the subjects of this post.

Other Field Notes

From Susan Treesh:
I had a Louisiana Waterthrush at Bamboo Brook County Park (actually, *in* Bamboo Brook!), and then a pair of Pileated Woodpeckers eating berries next door at Willowood Arboretum.

Editor’s Note: This is a geography note about Willowwood Arboretum. The Morris County Park Commission administers Willowwood which is in Chester Township. It is understood that the entrance, the fields, the dwelling and the gardens are in Morris County, in other words, the sections most people occupy when visiting. Only the back end of the property is in Somerset County. This is mentioned because eBird creates confusion when records are submitted from this place as it erroneously places the arboretum in Somerset Co. Using the following coordinates for eBird will place it correctly in Morris even if the location is not perfectly situated: 40.7372424, -74.7121811.

Upland Sandpiper, Olive-sided Flycatcher in Morris Co., Aug. 17, 2013

Upland Sandpiper at Great Swamp NWR

Simon Lane found an Upland Sandpiper on Pleasant Plains Rd., Great Swamp NWR this morning. This is his account: “Flushed from the field with the two small ponds on Pleasant Plains Road as I drove past. Flew off southwards over tree line. A first for me in Morris Co. in 14 years. I got a second glimpse of a largish shorebird flying high over pp road near the HQ entrance road and towards the HQ about an hour later – potentially same bird again.”

Interestingly, on August 13, 2012, an Upland Sandpiper was observed and photographed at the Bluebird Lot nearby on Pleasant Plains Road.

Last week at Sasso Tract (Sasso for short) there was a Golden-winged Warbler. This morning, there was an Olive-sided Flycatcher (OSFL) among the snags along Beaver Brook. The OSFL was recognized on hearing its signature song: “quick, THREE BEERS!” which it sang numerous times before being seen. Actually, John K. Terres’ mnemonic rendition of “look,THREE DEER!” is more appropriate for the mocosocoBirds area.

This interesting location will be visited and documented as the seasons progress. Other species today were Wood Ducks, Great Blue Heron, Downy, Hairy, Red-bellied and Pileated Woodpeckers, Northern Flicker, numerous Eastern Wood-Pewees, Great Crested Flycatcher, Red-eyed Vireo, Blue-gray Gnatcatcher, Cedar Waxwing, Blue-winged, and Yellow Warblers, Common Yellowthroat, American Redstart, Scarlet Tanager, Rose-breasted Grosbeak, Baltimore Oriole and other typical species of the area.

Birds of the Long Hill Wetlands, Aug. 15, 2013

Red-headed Woodpecker, Long Hill, NJ, Aug. 15, 2013 (digiscoped by Jonathan Klizas).

Most mocosocoBirds readers are familiar with Glenhurst Meadows in Warren Township. Glenhurst was formerly known by the unfortunate name of Warren Green Acres, which some people continue to use. It is unfortunate and confusing because there are other parcels of land in Warren Township other than Glenhurst that fall under the aegis of Warren Green Acres.

Glenhurst Meadows was the Cooper Farm before it became a golf course, a very wet golf course and eventually a Green Acres site. Adjacent to Glenhurst is the former Wagner Dairy Farm, now called Wagner Arboretum. Birders generally combine these areas into one entity. It is one of the most productive birding locations in northern Somerset County.

Less known is the area north of the Passaic River from Glenhurst. This is the southern section of Long Hill Township in Morris County. Placards posted on the trees identify it as administered by the Morris County Park Commission. There is no information about a name for this area although it could be called Passaic River County Park like many other sections in Morris Co. The Passaic River Coalition has some land parcels near this locale that are labeled Long Hill Wetlands I, II and III. This name is appropriate for the entire area between the Passaic River and Valley Road. It is in Long Hill and it is wet, very wet. That is justification enough for a name – Long Hill Wetlands it is.

The Long Hill Wetlands are located in Stirling, Millington, and Gillette south of Valley Road to the Passaic River and extend from the eastern boundary of the township on Hillcrest Road to the western boundary along King George Rd.  At this point Long Hill Wetlands meets the King George Road Wetlands Preserve and Dead River Wetlands in Somerset Co. This is a big playground. It is predominantly a Pin Oak bottomland flood plain along the Passaic River. Very little of this territory has been explored.

Millington was my boyhood home in what was then called Passaic Township and decades later became Long Hill Twp. For those old enough to remember, Old Stirling Road (S. Main Ave. on some maps), the extension of Main Ave. in Stirling south of the blinker (for those who remember the blinker), was a complete road to Mountain Avenue in Warren Township consisting of dirt and gravel. It was barely maintained, if at all. Only locals knew about it, especially curious, teenage boys filled with exploratory urges. Sometime after the 1970s, the road was decommissioned. Besides repeated flooding by the Passaic River, the road had become a garbage dump for those less endowed of intelligence. The small bridge spanning the Passaic River deteriorated and was removed. Old Stirling Road became a dead end on the map. The road south of the river (Somerset Co.) is overgrown and impassable. The road north of the river (Morris Co.) is now part of the Morris County Park Commission. Once upon a time on the Internet it was read that Morris County was rated as the best run county in New Jersey. This writer tends to agree.

Recent explorations to assess the birdability of the Long Hill Wetlands reveal the following:
• There are no trails.
• It is wet.
• It is mucky.
• It is buggy.
• There are lots of trees and habitat.

The road to the river is a productive stretch to bird but limited in scope. A power line offers the only reasonable access into the area. After that, one is on their own. The path near the third power tower heading west from the road is perpetually flooded ending that route. One can make a detour around that but the footing is treacherous with water, chest-high vegetation, fallen trees, vegetation hiding fallen trees, vegetation hiding water, etc., etc.

What is the allure of Long Hill Wetlands? If Glenhurst Meadows is such a rich area, why can’t Long Hill Wetlands get some of the overflow. Morris and Somerset are two of the wealthiest counties in the United States of America based on per-capita income. These sister counties should share the riches, n’est–ce pas? Red-headed Woodpeckers are an example. Many Glenhurst reports from the past few years were of Red-headed Woodpeckers actually in Morris County as well as Somerset County. Mike Hiotis documented some Red-headed Woodpeckers at Glenhurst in a JerseyBirds post yesterday. Other reports in 2013 from Glenhurst fueled my interest in exploring Long Hill Wetlands this morning. The reward today was the Red-headed Woodpecker pictured above. All six regularly occurring woodpecker species in New Jersey (sans Yellow-bellied Sapsucker) were observed this morning. One cannot help but think that other interesting finds are here throughout the year. If you go, make sure you bring boots, waders or a boat depending on the water levels. Interestingly, mosquitos were not an issue this morning. Other visits have proven them brutally inhospitable. Remember, this is not an easy place to get around in. A link to today’s bird species list is here.

The road towards the river is as sane as it gets at the Long Hill Wetlands.

Bird migration forecasting links, Aug. 13, 2013

As the season gets deeper into migration, here are some blogs and tools available for monitoring bird migration forecasts.

  • BirdCast – The Cornell Laboratory of Ornithology’s forecast division with weekly forecasts and analysis for the United States.
  • Tom Auer’s Blog – New England focus and pertinent for New Jersey.
  • Woodcreeper – Dave La Puma’s venerable blog has a mid-western focus these days but continues to be useful for the Mid-Atlantic States.
  • Windmap – With a high rating on the cool factor, this stunning visualization was created by Fernanda Viégas and Martin Wattenberg, the co-leaders of Google’s “Big Picture” visualization research group in Cambridge, Mass. More information about the project is here.
  • U.S. national reflectivity composite loop map courtesy of the University of Wisconsin: tempest.aos.wisc.edu/radar/uscompjs.html.

Golden-winged Warbler at Sasso Tract, Rockaway Twp.

An adult male Golden-winged Warbler was seen this morning at the Sasso Tract, Rockaway Twp. The individual had all the proper plumage details and looked as pure as this species can these days. There were no obvious signs of hybridization with Blue-winged Warbler. The warbler was silent. Some of the species present were: Pileated Woodpecker, Eastern Wood-Pewee, Eastern Kingbird, Red-eyed Vireo, Blue-gray Gnatcatcher, Cedar Waxwing, Blue-winged Warbler, Golden-winged Warbler, American Redstart, Common Yellowthroat, Scarlet Tanager, Rose-breasted Grosbeaks in various plumages, Indigo Bunting and other species typical of the area. A more detailed description of the Oak Meadows/Sasso Tract area is forthcoming in the future. For now, the only sane way to get to Sasso is via the Oak Meadows ball field on Pillar Drive. Walk completely around Pillar Pond until you come to an overgrown opening in the woods and try to follow the path (sometimes it is there; sometimes it is not) for over one mile. Keeping Beaver Brook to your north is a good navigation aid.

From Harvey Tomlinson in Montgomery Twp.:
Selody Sod Farm had only Killdeer.
Nearby Skillman Park had 4 Am. Kesterl, 4-5 Grasshopper Sparrows, 11-12 Savannah Sparrows, 25+ Chipping Sparrows and 2 Blue Grosbeaks.

Harvey’s photos are on his Flickr photostream.

Other Field Notes

From Susan Treesh:
Had 3 Red-shouldered Hawks calling in Somerset this morning – tracked down one just to be sure. Also a very young Prairie Warbler, still showing some downy feathers, foraging in a family group.

Butterfly Note

On Saturday afternoon, Aug. 10, a White Admiral (Limenitis arthemis arthemis) on Buddleia surprised this writer while looking out the front door of our home. It stayed for ~15 minutes, moving from flower head to flower head, flying to and staying on the roof of the house for a short time before returning to the Buddleia. Eventually, it flew across the street, over our neighbor’s house and out of sight. I was informed by Jim Springer, Vice-president of NABA (North America Butterfly Association), that this is the only reported White Admiral in New Jersey for 2013.

The species account of Red-spotted Admiral for New Jersey (covering Red-spotted Purple and White Admiral) is at the North NJ NABA chapter’s excellent web site: www.naba.org/chapters/nabanj/butterflies/red_spotted_admiral.html.
The North Jersey Butterfly Club’s main page is here.

Mississippi Kites in Basking Ridge; Glossy Ibis in Morris Co., Aug. 9, 2013

Mississippi Kites

Two sub-adult Mississippi Kites, one with missing tail feathers, were viewed this afternoon at 2:30 over Finley Avenue in Basking Ridge near St. James Church and School (Harvey Tomlinson). They were last seen moving along the ridge in a southerly direction.

Glossy Ibis

One Glossy Ibis was found at Melanie Lane Wetlands early this morning. The Ibis landed briefly in the southern section of the area and then took off and flew towards Rt. 10. A Great Egret and two Belted Kingfishers joined the usual species of this wetland. This is the fourth sighting of Glossy Ibis at this location in 2012-13. Here are the other three:
1. June 21, 2012
2. August 5, 2012
3. April 27, 2013

Belated report of Swallow-tailed Kite in Morris Co. from Aug. 3, 2013

Scott Barnes reported the following to mocosocoBirds a short time ago: John Macaluso “gave a very credible description of a Swallow-tailed Kite he saw over his house in Chester on Saturday Aug 3. The bird was soaring near the intersection of Pleasant Hill Rd and Reger Rd.” As Scott says: “Who knows, with all the dragonflies that must be present around the Black River, maybe there’s an off-chance the bird is sticking around somewhere nearby”.

This represents only the second Swallow-tailed Kite in Morris Co. since 1887(!) according to NJBRC accepted records. One of the last reviewable Swallow-tailed Kites was seen and photographed in the Great Swamp, May, 2011. As of January 1, 2012 Swallow-tailed Kite is no longer a reviewable species in New Jersey.
