28 October 2020
Bird Notes: Daylight Savings Time ends this weekend, so set your clocks back on Saturday night into Sunday morning. OWL WALK - we are considering one to start at about 5:00pm on Wednesday or Thursday of next week, 4-5 November. We had originally planned for Monday evening but the forecast for Mon-Tue is for cold weather and strong winds from the north. The owl walks will be in the North End of Central Park on Thursday November 5th (meet 4:30pm) and Sunday evening 8 November (meet 4:30pm) - both walks meet at 106th street and 5th Avenue - see the SCHEDULE page of our web site fr details. We are after a pair of Barred Owls. We'll do our best to bring them to a perch in the open for great photo ops.
Black-capped Chickadee, Central Park (Turtle Pond), 25 October 2020 by Deborah Allen
Nearly half of all North American bird species breed in the boreal forest, so understanding why and when (the periodicity) of large southbound movements (irruptions) is a topic of some importance. Without a doubt these irruptions are related to climate, but how? In this Newsletter we present some local numerical counts of Pine Siskins during the 2008 irruption year, as well as the abstract/discussion of a 2015 scientific paper on how climate drives seed-eating boreal birds to our area from north to south, and also from west to east. The Pine Siskin is not "showy," but it is amazing to understand how climate (cool and wet, vs. warm and dry) affects food supplies of the boreal forest driving nomadic seed-eaters to our area. Birds such as Evening Grosbeaks, White-winged Crossbills and Pine Siskins migrate by day probably because they stop to feed along the way - but recently, Pine Siskins were found to also migrate at night, as goldfinches are known to: https://tinyurl.com/y59zqujt

In this week's Historical Notes we present 1989-2020 information/observations about the Pine Siskin in the NYC-LI-tristate area. Some of the information comes from published scientific articles, as well as anecdotal counts of numbers of migrants seen per hour (or day) at established migration watch site: (a) the % occurrence of the rare green morph (https://tinyurl.com/yxvrp4mr) Pine Siskin in flocks of "normal" plumaged birds; (b) a Pine Siskin banded in Pennsylvania in 2009 turning up four months (and 2,000 miles) later in Alberta, Canada; (c/d) October 12, 13 and 20 (2008) counts of migrating Pine Siskins in Westchester County, as well as Lighthouse Point (New Haven) Connecticut; (e) 9 November 2008 counts of migrant siskins in New Jersey; (f) 30 October 2018 counts of migrating siskins (and Purple Finches) on Long Island; (g) October 25-26 (2008) big days of Pine Siskins in Central Park; (h) 2 November 2008 migration counts of Pine Siskins on Staten Island and in New Jersey; (i) a 2015 article on the importance of climate (cool/rain) causing a failure of conifer seed crops that drive boreal seed-eating birds south (including Pine Siskins) - and an interesting investigation of what drives seed-eating birds south, and also west to east; finally (j), a 2017 paper on the ages, timing of migration and condition of migrating Pine Siskins banded at a landfill (the Meadowlands) in New Jersey.
Nelson's Sparrow, Central Park Pinetum on Tuesday 27 October (above), Deborah Allen.
Some Comments on Nelson's Sparrow: In fresh plumage (fall) has an orange throat, upper breast, and flanks and a weak malar. The malar is the short throat stripe closest to the throat bordering it on either side. The upper breast and flanks have dark streaks, these streaks being strong and distinct on the mid-western and northern Canadian subspecies of Nelson’s, blurry on the eastern subspecies of Nelson’s Sparrow (Ammospiza nelsoni subvirgatus). According to Beadle and Rising the mid-western (Ammospiza nelsoni nelsoni) and northern Canadian (Ammospiza nelsoni alterus) are “indistinguishable” in the field. Chris Elphick, posting on the Connecticut listserve ctbirds, has suggested that hybrids between Nelson’s and Saltmarsh may resemble the mid-western subspecies of Nelson’s Sparrow. The very similar Saltmarsh Sparrow has a whiter upper breast with more distinct streaking, a stronger malar, and is less orange on the throat. Deborah Allen

Red-tailed Hawk (adult); Central Park (Belvedere Castle) on 25 October by Deborah Allen
The fine print: Our walks on weekends meet at 7:30/9:30am at the Boathouse Restaurant (approx. 74th street and the East Drive). Please note: the Boathouse is not one of the buildings that surround the nearby Model Boat Pond - people make this mistake all the time! Fridays we meet at Conservatory Garden; Mondays at Strawberry Fields - check the "Meeting Points" page of this web site for exact meeting location.
Our home phone is 718-828-8262...and Deborah's cell is: 347-703-5554. Email is (email@example.com). If you are lost and trying to get to the bird walk, call Deborah's cell phone...but remember on weekends there will be 2-3 other people calling who are also lost - please be patient. If in doubt about whether a walk will take place or not the morning of the walk: check the main landing page of this web site as well as the "Schedule" page - if the walk is cancelled, information will be posted there by 6am the day of the walk, and usually by 11pm the night before. If still confused and as a last resort, call us at home - if no one answers it means we left for the bird walk. We end all our Central Park walks (except Fridays) near the Boathouse at about noon; you can get a cup of coffee and a muffin there (around $6 total) - though the Boathouse is closed right now and will re-open in April 2021 according to the owners. Walks last about 3 hrs (less if hot or rainy), and you can leave at anytime - we won't be offended. If you need directions/help to your next destination, just ask someone on the walk - we aim to please.

Here is what we saw last week (brief highlights)
Friday, 23 October 2020 (Conservatory Garden at 8:30am): was a total wash-out. It rained (well misted) most of Friday morning...
Deborah's List of Birds for Friday, 23 October: No Bird Walk - RAIN today!
Sat-Sunday, 24-25 October 2020 (Boathouse Restaurant at 7:30am and again at 9:30am): Please note: the bathrooms at the Boathouse are NOT open. However, we do pass two other sets of bathrooms on the walk. Saturday, 24 October: 6 warbler species seen today including a Black-throated Blue, but our best species was only briefly seen by all: a Yellow-billed Cuckoo flew into the tree adjacent to Belvedere Castle while I was playing the alarm calls of a vireo. It then sat motionless - and everyone got a good look at it, as it flew away about two minutes later. Also this morning, wonderful Pine Siskins coming in from the blue to land near us (and on us) at Shakespeare Garden and the Pinetum; and a flock of Purple Finches also at Belvedere. On 25 October (Sunday) a flyover male Northern Harrier and a few minutes later, a second year Bald Eagle. The overnight winds had brought in more Red-breasted Nuthatches, Pine Siskins - and lots of Black-capped Chickadees. The best bird of the day was a Great Crested Flycatcher that was perched atop the White Pine tree in Shakespeare Garden.

PINE SISKIN - RECENT INFORMATION
The Occurrence of Green-morph Pine Siskins in the Siskin Irruption of 1989-1990
An intense, nearly continent-wide irruption of Pine Siskins (Carduelis pinus) began in August 1989 and continued through the 1989-1990 winter (see numerous field reports in American Birds, Vol. 44(1) through Vol. 44(5)). Siskins penetrated as far south as the Gulf States and Florida in the East, and at record early dates in Texas. In many areas they lingered into April and May, later than usual. In some Midwestern states, they lingered into the following summer. Only in the Southwest and the Pacific Coast states was there little evidence of their appearance. At three feeder/banding stations in the Schenectady, New York area, I banded 4,045 Pine Siskins between January and June 1990 and assessed the occurrence of the rare green morph of this species
Birds fitting the following descriptions from McLaren et al. (1989) of the green morph were noted. They described this morph as follows: (1) "Dark grayish-green on the back, with strong yellow wing and tail patches, a greenish- yellow rump, and tinged with yellow on the head and underparts." (2) "These greenish Pine Siskins look like ordinary ones that have lost their heavy brown streak, revealing an underlying pattern of gray and yellow that blend into green hues overlaid by a fainter remnant of the original streaking." (3) "Green morphs always lack the heavy, dark streaks usual in brownish Pine Siskins, and some have almost no streaking below. When present, the streaks appear broad and diffuse..."
Overall, the total occurrence of green-morph siskins was 1.26 percent. This compares reasonably with McLaren et al.'s (1989) finding of about one percent. They examined 1,525 specimens from six museum collections, finding 15 green morphs (0.98 percent). It was at this time of return migration [April-May] that occurrence of these green morphs was at its peak
It would be helpful for banders and field observers to record more data on green-morph siskins in subsequent invasions to assess whether their occurrence varies geographically as well as temporally; and at the same time, to take heed of McLaren et al.'s (1989) excellent advice on separating Eurasian Siskins (Carduelis spinus) which might occur in these invading flocks of Pine Siskins.

Pine Siskin banded in Northampton County, Pennsylvania, found in Alberta, Canada From: Paul H Karner 9 August 2009
I received from the BBL data on a Pine Siskin that I banded in my yard here in Bangor, Pa. on 15 March 2009. It was found on 27 July 2009 just south of Edmonton, Alberta, Canada. This is just under 2000 miles in a straight line! So just how many miles did this Pine Siskin (PISI) fly? I'm delighted with this recovery. This is my first return on one of the 453 PISI I banded in 2009. Will any of these banded PISI's return to my yard this coming season?

Major Pine Siskin movement - Westchester County (October 2008)
From: Cameron Rutt
Date: Monday 13 October 2008
Apparently, the past few days have brought a surge of Pine Siskins throughout the region, from the New England states to at least Pennsylvania and New Jersey, with seemingly fewer birds reported south of there. Chestnut Ridge Hawk Watch, near Bedford, Westchester County, had its first Pine Siskins of the season on Saturday (10/11) with 20 birds in 3 flocks. The siskin count increased yesterday (10/12), when 175 birds were conservatively recorded in 7 passing flocks.
However, both of those days fell short of the massive movement that took place all day today at Chestnut Ridge. Shortly after I arrived at the hawk watch this morning, a calling flock of approximately 60 birds flew directly overhead, the first sign of what would be an impressive passage of birds. Tait Johansson joined me up at the watch and together we counted/estimated the knots of flyby siskins, reaching a final tally of 2,524 birds! Altogether, 73 flocks were noted with flock sizes ranging from 2 to 133 individuals. Among the more noteworthy flocks were groups of 90 (twice), 85, 80 (twice), and 75 birds. The average flock, though, was about 35 birds strong. Siskins continued flying until shortly after 5:00 PM (DST) with a flock of 90 at 5:05 and 3 more at 5:20. With the addition of Lighthouse Point's and Quaker Ridge's siskins today, 6,204 were amassed between these three hawk watches.
Hour-by-hour count (starting with the 9:00-9:59 AM hour DST): 223, 502, 84, 249, 205, 319, 268, 581, and 93.
Other regional high counts from the past two days:
12 Oct 2008:
265 - Pack Monadnock, NH
500+ - Blueberry Hill, MA
78 - Lighthouse Point, CT
140 - Montclair, NJ
79 - Hawk Mountain Sanctuary, PA

Pine Siskin flight continues - Westchester County (October 2008)
From: "Cameron Rutt"
Date: Monday 20 October 2008
Echoing what both Ken Feustel and Matt Young pointed out in recent days about good numbers of Pine Siskins, Chestnut Ridge (near Bedford, Westchester County) has continued to have some impressive siskin flights. Today's flight of over 1261 birds (in 62 flocks) was this site's second major push for siskins this fall. Today's noteworthy passage came exactly one week to the day after the more sizable siskin push on 10/13 (2524).
Today's hour-by-hour count (starting with the 9:00-9:59 AM hour DST):
111+, 132, 269, 22, 123, 70+, 182, 352
Two flocks were heard only, thus the "+" in the hourly breakdown. I found it interesting that in our four best siskin days, the mid- to late afternoons have been especially productive. In fact, on our two best days (10/13, 10/20), the 4-5 PM hour has had the most siskins of any hour in that day. Finch flights are typically something that I associate with early mornings.
Additionally, today's average flock only contained about 21 birds each, this compared to 35 bird flocks a week ago. Ken Mirman, Tait Johansson, and I have continued to keep track of the Pine Siskins at Chestnut Ridge over the past week. With today's addition, this makes 5211+ Pine Siskins (201 flocks) in the last week and a half (10/11-10/20)!
10/11 - 20 (3 flocks)
10/12 - 175 (7 flocks)
10/13 - 2524 (73 flocks)
10/14 - 92 (4 flocks)
10/15 - 31+ (3 flocks)
10/16 - 7 (2 flocks)
10/17 - 152+ (10 flocks)
10/18 - 446 (15 flocks)
10/19 - 503 (22 flocks)
10/20 - 1261+ (62 flocks)
Finally, Lighthouse Point, CT, has continued its Pine Siskin onslaught with back-to-back days of 1340 (10/19) and 1300 (10/20) birds.

Date: Sunday 19 October 2008
259 diurnal raptors with strong NNE winds and plenty of cloud cover. The weather folks predicted 0% clouds which would have been a disaster for counting.
The Pine Siskin movement was spectacular. The totals below were mostly comprised of early morning fly-overs, and as siskins went through in flocks of 10-100, other birds were swirling everywhere. Many went uncounted as I tried to focus on the hawks.
4 RT Loon, 25 Com Loon (including a single flock of 23!), 2 Great Egret, 63 Canada Goose, 7 Brant, 5 scaup sp., 1 Chimney Swift, 88 Blue Jay, 621 Tree Swallow, 12 American Pipit, 4 Palm Warbler, 11Yellow-rumped Warbler, 609 Red-winged Blackbird, 79 Common Grackle, 131 Brown-headed Cowbird, 160 unid. Blackbird, 13 Purple finch, 4 House Finch, 1340 Pine Siskin, 355 unid. finch (distant flocks resembling those of Pine Siskins, and almost certainly Pine Siskins).

Subject: Impressive siskin flight at Jones Beach (November 2008) From: Seth Ausubel Sunday 9 November 2008 I estimated 4,200 pine siskins in this morning's flight at Jones Beach West End, from 7:30-9:45. There were flocks of several hundred birds at time alighting in the pines at the turnaround. Other birds in the flight were approximately 1700 American goldfinches, 900 American robins, 650 red-winged blackbirds, 500 cedar waxwings, and 50 purple finches. No crossbills. A dickcissel was around the exit ramp of the West End 2 parking lot north of the pavilion, and 2 vesper sparrows were in the median near the cottonwood tree. There are at least 2 tufted titmice around, probably more. Seth Ausubel Forest Hills, NY
Subject: Cave Swallows and Pine Siskins - Montclair NJ Hawk Lookout (Essex Co.) From: Justin Bosler Sunday 9 November 2008 Hello JerseyBirds, I haven't done too much perusing of the listservs yet, but there must've been a considerable flight of Cave Swallows across the region today, 9 November. It was certainly the type of November weather that results in a flight of Cave Swallows along the Atlantic seaboard as they are pushed eastward by post-front westerly winds. At 2:35 PM, I spotted 2 swallows zipping around to the ENE fairly low over the eastern slope of the ridge. After several seconds of frantic scanning, I was treated to nice scope views of 2 CAVE SWALLOWS. I lost track of the swallows shortly thereafter as I went for my camera, however, both swallows presumably continued downridge as I last saw them flying in that general direction (more or less toward the hawkwatch platform). The PINE SISKIN irruption continues with a new single-day high of 890+ passing the Lookout today. Although to a lesser extent, PURPLE FINCHES are also staging a southward irruption. Today's 100 was relatively unimpressive after a few late October single-day counts exceeding 150 birds. Singles to small flocks are the norm with the largest flock numbering 38 birds. Today's highlights of 77 individual raptors include singles of NORTHERN GOSHAWK, AMERICAN KESTREL, and MERLIN.
