When a beach flight stands out as memorable to Ken, it means something; he's 
seen a lot of big flights out there. In trying to take stock of the day, I find 
myself not only agreeing with Ken, but becoming convinced more and more that 
this flight was unusually intriguing in many ways.

I was part of a group that conducted a stationary morning flight count, and my 
companions will attest that our total of 5 Hairy Woodpeckers had me freaking 
out a little bit. A quick comparison to my past records explains why--and also 
affirms Ken's perception of this species' usual scarcity on the barrier beach: 
since 1996 I've tallied just 8 Hairy Woodpeckers, vs. 28 Red-headed Woodpeckers 
at RMSP and the adjacent Lighthouse Tract. Among other relatively (or 
allegedly) sedentary species moving this morning were 12 Downies, 20 
Red-bellies (possibly a local daily max), and a White-breasted Nut, and our 
total of 28 Northern Cardinals in obvious morning flight was a true spectacle 
of nature!

Of course, these 66 novelties were gleaned from a deluge of literally tens of 
thousands of birds flying past, and I'm also reminded of another point that Ken 
made, that there is no completely adequate way to count birds during these 
events. Each type of effort has advantages and demerits, and each will be 
overwhelmed on a day like this. The most difficult species to count on days 
like this is, in my opinion, Myrtle Warbler, owing to its diverse modes of 
passage through the airspace and puckerbrush, and this is the species for which 
our stationary estimate differs most from Ken's. Although I haven't had a 
chance yet to completely decipher my notes, I'm convinced that we saw on the 
order of 20,000, passing throughout the morning on a broad front from 
oceanfront to bay, and at a wide range of heights. Although I didn't recognize 
at the time that this flight was larger than last Sunday's, my sample counts 
and rate estimates clearly indicate that it was immense. Our Pine Siskin tally 
was about 3,600; the difference from the Feustels' estimate in this case owing 
to the habit of this species' flocks' of calling least when largest; large 
flocks of ca. 100 routinely passed almost silently along the dune line.

But the most intriguing thing about this morning involved the species that 
sometimes, but not always, commit to obvious morning flight. As might be 
expected at this date, Hermit Thrushes were heavily represented in the 
overnight flight, but these birds would not ordinarily be expected to move east 
to west after sunrise. Today, as on 3 Nov 2006 (see note, copied below), they 
were very frisky and pushed bush to bush quite a bit and even persisted in 
giving nocturnal fight calls from the brush, throughout this bright, glary day 
(one called as late as 3:00 pm, under full sun and a raging westerly breeze 
that streaked the Atlantic Ocean with white, as Eileen Wheeler and I discussed 
whether we were lucky or unlucky to have been weathered out of today's 
scheduled pelagic--lucky, I say!). For purposes of comparison, my drive-around 
tally of road-side Hermits Thrushes this afternoon was 65 today, vs. 422 on 3 
Nov 2006. Among other species that sometimes do and sometimes don't engage in 
morning flight at Fire Island, Juncos and White-throated Sparrows were all in 
today--these two species were streaming east to west along the inlet shore at a 
prodigious rate for the first 40 minutes after sunrise. Again, I need to work 
carefully  through my notes, but the back of the envelope estimates are 6,000 
Juncos and 2,000 White-throats--both exceptional totals for a stationary count 
in fall. Even more amazing to me is my total for Ruby-crowned Kinglet, which 
overwhelmingly dominated Golden-crowned in the morning flight, with ca. 800 
passing, mostly bush to bush between 7:20 and 11:50.

And other mysteries remain. Song Sparrows were strikingly under-represented 
today, especially given the huge pushes of Juncos and White-throats, and it 
wasn't until my afternoon mop-up that I saw my first Swamp Sparrow. Taking 
everything into account, I think that Song Sparrows were genuinely scarce in 
last night's flight (and further under-detected in our stationary counts, 
because they don't engage in morning flight). But the paucity of Swamp Sparrows 
today was inexplicable--how could it be that I saw fewer Swampies than Hairy 
Woodpeckers!

I returned to Robert Moses SP on Friday afternoon and assessed the aftermath of
the first phase of this weekend’s flight. The diurnal migrants (Robins, 
waxwings,
blackbirds, etc.) were long gone by the afternoon, but various nocturnal 
migrants
had reoriented and assembled in enormous numbers.

Most shocking to me were the numbers of Hermit Thrushes and Chipping
Sparrows.

Hermit Thrush is a species we generally record in single digits and for which I 
can
find no previous triple-digit count in my records. Double-digit counts of 
Chipping
Sparrows are pretty routine, but triple digits are very unusual on the barrier 
beach.
In the morning, Pat and I had been amazed to count 80 Hermits (many which were
giving flight calls from the ground!) and 200 Chippies. On my return, I realized
immediately that many more of both had hopped in from the east and/or emerged
from the puckerbrush. By driving the loop road and circling the two main parking
lots at 25 mph, I counted 422 Hermit Thrushes easily visible along the grassy
margins.  This number does not include any I missed among the thousands of
White-throated Sparrows, nor the multitudes that later investigation proved were
still lurking within the vegetation throughout the park. Actual counts were 
simply
not possible for many other species, but I put some care into estimates of 
10,000
White-throated Sparrows (many more than in the morning) and 500 Chipping
Sparrows (like HETH, beyond any prior experience).

Saturday brought a very nice morning flight that seemed downright dull compared
to Friday’s. For most species, the numbers on the ground were much reduced from
Friday but still very impressive.  Chipping Sparrow was again an exception, 
with at
least 750 at RMSP alone. Chippies were unique among the abundant landbirds in
appearing in larger numbers on Saturday than on Friday. I’m used to seeing 
flocks
of Myrtle Warblers loping in from the east throughout the day during big 
flights,
but I cannot recall ever before seeing flocks of Chipping Sparrows materializing
above the Fire Island Lighthouse, flying in from the east, and settling down to 
feed
among the earlier-arriving hordes at RMSP.

Sunday was warm and relatively windless, with a further reduction in overall
numbers (though still very impressive by any normal standards). We scoured RMSP
again and finally ventured west to Jones Beach. We conducted another roadside
Hermit Thrush count and tallied 313 between Captree and West End, plus at least
50 more at West End itself.

Some new statewide maxima were set this weekend, and we are continuing to
collect records from the many observers afield on LI this weekend.

Best,
Shai Mitra
