Glaucous Gull continues at Budd Lake; Field notes, Mar. 8, 2013

From Alan Boyd:
Hi Jonathan – The Glaucous Gull was flying around the municipal beach at the south end of Budd Lake today about 1:30. It’s a striking bird in flight and I noticed it even before I turned off of Rt 46. There were only about 20 other gulls around, all Herring Gulls and Ring-billed Gulls. No sign of the Lesser Black-backed Gulls reported earlier in the week.

Most of the waterfowl on the water were at the back edge of the lake and it was too windy to scope them well – Alan Boyd

[Editor’s Note: This is the seventh day for the Glaucous Gull at Budd Lake]
—————
Lake Parsippany’s Common Merganser flock grew in numbers the last few days. 720 were counted on the lake this afternoon. And, yes, the same Aytha floating raft continues with 7 Redheads, approximately 60 Ring-necked Ducks and 15 Lesser Scaup. 17 Hooded Mergansers, 4 Ruddy Ducks and 4 American Coot continue as well.
—————
Other than 8 Bufflehead, a pair of Common Mergansers and a group of roosting gulls near the south end (not studied), Boonton Reservoir was practically birdless this afternoon.
—————
Check your feeders for Pine Siskins. Jennifer Books’ continues to get a pair at her feeder in Basking Ridge. Mike Hiotis commented on yesterday’s post that he had a pair in the birches in his yard on Thursday morning.

eBird.org published a must-read article today about the Rusty Blackbird, Unlocking the Rusty Blackbird Mystery. As the article states: “Rusty Blackbirds have experienced one of the steepest population declines of any once-common North American bird. Estimates from the last decade suggest that Rusty Blackbirds have experienced an 85-99% population drop over the past 40 years.”

Budd Lake was packed with 5,000 gulls and 8,000 Canada Geese as well as other waterfowl eight days ago on February 27. The gull numbers have dwindled day-by day but the quality of interesting species remains high. The Glaucous Gull is present for a sixth day. It was solitary on the ice while the wind-driven snow fell around it. The picture above was taken from Rt. 46 near the south end of the lake, not recommended during rush-hour, just to illustrate how the gull was a drive-by bird today. 2 adult Lesser Black-backed Gulls were present. 14 Redheads (4 drakes and 10 females) were a surprise close to shore at the north end. 60 Lesser Scaup drifted further out. At least 225 Common Mergansers were counted. A solo American Coot was also seen, possibly the same individual present all winter.

Lake Parsippany has the same waterfowl as reported yesterday including the seven Redheads in attendance for seven days.

From Jennifer Books:
I saw two Pine Siskins at my feeder in Basking Ridge late this morning..so they are obviously still around.

The immature dark morph Rough-legged Hawk at Rattlesnake Bridge Road in Bedminster Township was viewed by Jeff Ellerbusch this morning. It seems like two weeks passed since this individual was reported.
—————
Lake Parsippany held a fair number of ducks late today. A season’s high of at least 500 Common Mergansers were spread throughout the entire lake. The seven Redheads (4 drakes, 3 hens) remain in the Aythya raft which includes 85 Ring-necked Ducks and 15 Lesser Scaup. 3 Common Goldeneye drakes were almost missed among the many Common Mergansers in the fading light. 1 Northern Shoveler, 12 Bufflehead, 12 Hooded Mergansers 5 Ruddy Ducks, 4 American Coot as well as the usual 200 Canada Geese and 150 or so Ring-billed Gulls round out the totals on the lake. This is the best diversity on the lake in 2013.

Tree Swallow in Franklin Twp.; Field notes; NJAS Wildlife Art Gallery notice, Mar. 5, 2013

This afternoon, Jeff Ellerbusch found the first Tree Swallow of 2013 in the mocosocoBirds region. One was seen and heard along the D&R State Park towpath in Franklin Township. Unfortunately for the swallow, the weather forecast for the next few days does not bode well for insectivores. The Raritan River also held Lesser Scaup, Ring-necked Ducks, Common Goldeneye, Common Mergansers and Bufflehead.
—————
A tantalizing teal was viewed this afternoon at Finderne Wetlands in Bridgewater Township. A possible Eurasian Teal, or more likely an intergrade, was with the 30 Green-winged Teal in the west pond. The duck definitely lacked a vertical white stripe and appeared to have more prominent buffy facial stripes but a horizontal white stripe was not determined before the group of Teal flushed.
—————
No reports of the Glaucous Gull from Budd Lake today. It is not known if anyone looked.

Mike Wolfe did not find the Iceland Gull at Mt. Hope Pond or Mt. Hope Lake in Rockaway Township this afternoon.
—————
From Jennifer Books:
Late this morning my sister and I went birding at Lake Parsippany. I am happy to report that we saw 4 Redheads (life birds for us) mixed with about 100 Ring-necked Ducks and 1 female Ruddy Duck. In addition, there were probably hundreds of Common Megansers there as well as 4 Am. Coots, about 32 Canada Geese, a large number of Ring-billed Gulls, and 1 Mute Swan.

Isobel Wayrick Wildlife Art Gallery to Feature Work of Bernardsville Local, Joseph F. Pescatore

From March through May, the Isobel Wayrick Wildlife Art Gallery will feature the work of Joseph F. Pescatore, a local Bernardsville businessman (resident) and photographer. The Gallery is part of the New Jersey Audubon’s Scherman Hoffman Wildlife Sanctuary, also located in Bernardsville.

An avid birder and photographer, Pescatore brings to the gallery an innovative body of work created through a process known as digiscoping. This method of photography is ideal for capturing birds and other far away objects or animals because it involves attaching a spotting scope to a digital camera. Through digiscoping, Pescatore can photograph distant birds that he may not be able to get close to on foot, opening up a wide range of possibilities particularly of interest to wildlife photographers.

This exhibit will allow people to learn more about digiscoping and to see the types of images that can be captured through the method. The exhibit opens on March 1. The Scherman Hoffman Wildlife Sanctuary is located at 11 Hardscrabble Road in Bernardsville. For more information, call 908-766-5787, email shws@njaudubon.org, or check out the Scherman Hoffman section of the NJ Audubon website at www.njaudubon.org.

Glaucous Gull, Cackling Goose and Greater White-fronted Goose, Mar. 4, 2013

The continuing Glaucous Gull of Budd Lake was seen this afternoon by various birders. Mike Wolfe adds a pair of Cackling Geese seen close to shore.
—————
The Iceland Gull of Mt. Hope Pond was not seen this afternoon by those who looked. There are no reports, yay or nay, from this morning when the gull has been reliable the past few days.
—————
A Greater White-fronted Goose was with the hundreds of Canada Geese this afternoon on the main lawn of Duke Island Park in Bridgewater Township. Jeff Ellerbusch thinks this is the same individual originally found by Mike Newlon at the same location on November 27, 2011.

Photos of the Mt. Olive Redhead, Mar. 3, 2013

Mitch Van Beekum has graciously offered mocosocoBirds some photos he took this afternoon of the Redhead drake at Clark Drive in Mt. Olive Township. As stated in an earlier post, the drake is loyal to this corporate pond. The following images will display correctly on the web site but may only show a link in the email post (WordPress strips lots of HTML code from email transmissions). In the latter case: from the email, either select the subject heading at the top of the post to go directly to the web site, i.e. select Photos of the Mt. Olive Redhead or select the direct links to the photos at the bottom of the page. Thanks again to Mitch for sharing these wonderful images.

Glaucous Gull at Budd Lake report, Mar. 3, 2013

From Rosemarie Widmer:
I had the Glaucous Gull at 1:30 today 3/3/13 at the swim area right off of Rt. 46. I watched it eating the remains of a female Common Merganser for at least 1/2 hour.

[Editor’s note: The Glaucous Gull favors the municipal beach area at the south end of Budd Lake, at least in the afternoon. It certainly was not there early this morning, nor were the Lesser Black-backed Gulls. Mike Hiotis added a comment to the previous post about the Glaucous Gull, that he actually had it in the same beach area location at the south end and not the west shore he originally mentioned.]

Glaucous Gull continues at Budd Lake, Mar. 3, 2013

Mike Hiotis just called. He refound the Glaucous Gull at Budd Lake originally found yesterday. At least 3 of the Lesser Black-backed Gulls are in the same vicinity. The Glaucous Gull is currently along the west shore – not the easiest viewing location at the lake. Here is a map of the lake.

[Editor’s Note: correction to the location given above. Mike Hiotis comments that the location he saw the Glaucous Gull was actually the municipal beach area we call the south end, and not the west shore he described it as.]

Iceland Gull and Redheads, Mar. 3, 2013

Iceland Gull, Rockaway Twp., NJ, Mar. 3, 2013. The 3rd day it is known to be here (digiscoped by Jonathan Klizas).

The Iceland Gull of Mt. Hope continues as of this morning, Sunday, March 3, 2013. The Iceland Gull has appeared at Mt. Hope Pond shortly after 7:00 the past two mornings. The gulls (Iceland, 25-30 Ring-billed and a Herring or two) apparently roost at the back end, or hidden, part of Mt. Hope Lake. Today at 6:50, the gulls started flying around the back area of the lake for approximately ten minutes, the Iceland occasionally chasing some Ring-billeds. The Iceland Gull is unmistakable in flight. Besides it’s larger-than-Ring-billed-Gull size and pale coloration, it’s upper primaries are subtly, but noticeably, paler than its secondaries. After exercising at the the lake, the gulls start lazily flying over to Mt. Hope Pond one-by-one, less than a mile to the west. Yesterday at the pond, the gulls were alternately loafing, flying or foraging for a few minutes at a time. Today was all about loafing. The Iceland Gull never moved for the twenty minutes it was observed. The distant, digiscoped photo at the top of the page is the only pose the gull gave. The gull’s pattern the rest of the day is unknown. It was not at Mt. Hope Pond late in the afternoon on March 2. The possible alternate roosting site at Mt. Hope Lake is not viewable. If visiting Mt. Hope Lake, please respect the No Trespassing signs. Birders are tolerated at the end of Everment Road at the one car parking area and the tiny dock. The entire perimeter of the lake is administered by the Rockaway Township Sportsmen Club and owned by the Tilcon Corporation and is off limits. There is zero tolerance for trespassing (and they DO keep an eye on it).
—————
The Glaucous Gull of Budd Lake was not found this morning. It has probably left the area. In fact, the number of gulls has decreased day-by-day since Wednesday. Even Lesser Black-backed Gulls were absent today, or hidden. 550 Herring Gulls, 155 Ring-billed Gulls and 5 Great Black-backed Gulls were the tally for this morning. However, this is not to say that there will not be an afternoon build up of gulls – who knows? 4,000 Canada Geese remain as well as 40+ Lesser Scaup, 100+ Common Mergansers and 5 Hooded Mergansers. Budd Lake had 500 Ring-necked Ducks on February 28. There were none seen today.
—————
The loyal Redhead drake has returned to the corporate pond at Clark Drive in Mt. Olive Township. Any time this pond has had a thaw this winter, the Redhead is there. There was a high count of 18 Redheads on this same pond on Feb. 28, 2012.
—————
The Redheads of Lake Parsippany continue. What were 3 drakes and 3 hens last weekend has grown to 4 drakes for a total of 7 Redheads. They continue to hang out with the two other Aythya species in the lake: 76 Ring-necked Ducks and 21 Lesser Scaup. 2 American Coot are still present. Common Merganser numbers have grown to 238.

Ducks at Duke Farms; other field notes, Mar. 2, 2013

Duck numbers are growing at the ponds of Duke Farms in Hillsborough Township especially Ring-necked Ducks. Jeff Ellerbusch tallied the following today:
Canada Goose – 150
American Wigeon – 29
Am. Black Duck – 14
Mallard – 105
Northern Pintail – 4
Ring-necked Duck – 510
Common Merganser – 10
also 14 Killdeer.
—————
From Jennifer Books:
I stopped by the Verizon Headquarters in Basking Ridge this afternoon to check out the body of water behind it. It yielded 8 ring-neck ducks (mostly males), 15 hooded mergansers (11 female/4 male), and 1 female common merganser.

I also made a quick stop at Loantaka Brook Reservation but found the pond there surprisingly empty, even of geese. All I saw there were 2 Canada Geese. Even the Mute Swan disappeared.

Late this morning I had one Fox Sparrow visiting my bird feeders. I saw about 5 of these birds visiting months ago, and that was the first time I had seen any in years! Today I also saw what I believe was probably the same flock of goldfinches where the Pine Siskins had been mingling with, but no sign of the Siskins.
