Here's some analysis now that 6 Dorchester County, MD, fall bird counts
have been completed on the 3rd Saturday of September, 1996-2001.  These are
essentially Big Days with pretty careful recording of numbers also.  I have
never done Big Days in the fall until these so it is still a relatively new
and evolving dimension, or, "the dew was still on her", as F. Scott
Fitzgerald described a young woman in "This Side of Paradise".  So, with
apologies to FSF, the dew is still on the September Dorchester bird count.
Total species seen so far: 177.

The route is:  Hooper's Island in the morning, Blackwater in the late A.M.
to early P.M., Hurlock W.W.T.P. area in mid-afternoon, and Elliott Island
the rest of the day.  Usually goes from c. 5:45 A.M. until 8 P.M.  Species
totals vary from 106 (1996) to 133 (2000).  Unless there is a good
passerine flight (i.e., cold front) there is no shot at getting over 125.
On a warm day with no landbird flight warblers can be practically
non-existent.

This is a most enjoyable day since, unlike the spring counts, it is not an
all-nighter, is about 50 miles shorter (i.e., 130 mi.), and lacks the
pull-out-all-the stops, take-no-prisoners, grinding intensity of the May
counts.  However, with each passing year it gets more frantic, especially
since fall species totals occasionally surpass some of those on the lower
end of the spring counts in May.  As with the spring counts these are one
party affairs.

Sample species annotation:  Pied-billed Grebe (1,2,4,1,3,0; those are
totals for years 1996 through 2001 respectively).  Surprising since this
species is scarce here.  To get them thus 5 straight years is interesting.


Brown Pelican:  0,0,0,8,0,4.  In as much as counts of hundreds are a
regular occurrence almost within sight of the fall route this is
surprising.

HERONS, what with the year's young combined with post-breeding dispersal,
are in better supply than in the spring with highs such as:  Great Egret
130, Snowy Egret 155 (twice), Tricolored Heron 31 & Cattle Egret 93.

WATERFOWL:  An excellent time of year for dabblers with highs of Wood Duck
61, Green-winged Teal 675, Mallard 595, pintail 50, Blue-winged Teal 175,
shoveler 129 & wigeon 110.  Snow Geese seen 4 of 6 years.  Mute Swan high
285.  Canada Goose high 1,750, essentially before any migrants.

RAPTORS: with the fall flight (spring flights are close to non-existent
here) raptors are commoner than in spring.  Sharp-shinned Hawk:
9,8,17,4,36,17.  American Kestrel:  5,12,14,7,22,9.  Northern Harrier:
20,6,12,11,11,5.  Osprey is surprisingly scarce here in the fall:
11,7,1,7,7,4.  Bald Eagle:  31,22,21,35,30,30;  rock solid just like the
rest of the year.  Broad-winged Hawk:  One splendid flight of 543 in 1996,
excellent for the Eastern Shore.
Merlin:  2,2,1,1,1,0.

Common Moorhen:  0,5,18,0,5,14.  Has increased in Dorchester in recent
years.

RAILS:  I get so tired of tapeing for Virginias in May that I do little
tapeing in fall.  As usual there is the dynamic duo - Virginia Rail:
13,12,10,6,3,6 and Clapper Rail:  8,8,5,4,4,5.  We had 2 Kings in 1997 and
single Soras in 1996 & 1997.

SHOREBIRDS are mostly scarcer than in the spring, except for Western
(2,1,2,0,4,0) and Pectoral (11,12,6,1,5,31) Sandpipers.  Common Snipe:
3,1,3,1,1,5; I usually think of snipe as mostly a bird of gloomy, raw days
in November and March or early April and was surprised to see them recorded
every year so far this early in the season.  15 species was the best total,
in 2000.  Notable were 75 Sanderlings at Hooper's Island in 2001.

Caspian Tern:  45,115,20,35,18,24.  Much more common than in spring.

OWLS:  Old reliables - Eastern Screech-Owl:  6,7,3,7,3,2.  Great Horned
Owl:  4,5,1,13,2,6.  Single Barred Owls 3 years.

Yellow-billed Cuckoo:  1 in 1999 the only cuckoo so far.

Whip-poor-will:  2 calling at dusk n. of Savannah Lake along the Elliott
Island Rd. in 1999, just like it was spring, were surprising.

Belted Kingfisher:  5,4,6,5,3,1.  Much better than spring totals.

Hairy Woodpecker:  1 in 1997 the only one.  This somewhat scarce species
can be rather cryptic and is missed sometimes in the spring, too.  Of
course they're there; one just has to luck onto them.  Other woodpeckers
about the same as in May except there are more flickers.

Horned Lark:  0,0,0,0,1,6.  The field vegetation has grown up so they're
hard to come by.

VIREOS:  Just White-eyed and Red-eyed so far.  Will have to do better.

Fish Crow:  9,2,4,12,2,0.  Hard to understand.  Some other times of the
year one can see hundreds or even a thousand or two in a day.

Marsh Wren:  0,1,2,1,1,2.  Seaside Sparrow:  3,7,2,2,1,1.  Almost as if it
were winter, these abundant breeders here are mostly gone "underground" at
this time of year, detectable by their call notes at dawn or dusk or
responsive to screech owl calling, otherwise mostly out of sight.

American Robin:  6,10,6,6,40,45.  Often scarce in September.

WARBLERS:  Best so far was year 1999 but with only 14 species, on a good
flight day.  13 species is 2nd best in 2000 that also saw the highs for
Swainson's Thrush, Great-crested Flycatcher, Ruby-crowned Kinglet,
Rose-breasted Grosbeak, and Blue-gray Gnatcatcher.  So-called
spruce-montane-northern warblers are easier to find in the fall than in May
(i.e., Cape May, Tennessee, Bay-breasted, Blackburnian et al.).  But a bad
warbler day in September is much worse than a bad warbler day in May.

Eastern Towhee:  0,4,0,1,0,0.  Too early for migrants, resident birds are
undercover.

SPARROWS are scarce here in early fall, except for Savannah Sparrow:
34,24,3,3,10,8.  Different story for Song Sparrow: 0,1,1,2,1,1.  Chipping
Sparrow:  3,10,2,1,4,0.  Field Sparrow:  0,0,0,2,0,0.

Bobolink:  4,3,35,12,30,7.  The 3rd Saturday is past their migration peak
as it is for Baltimore Oriole (1,0,1,1,0,0), Orchard Oriole (never),
Worm-eating Warbler (never), Purple Martin (3,105,0,0,0,0), Yellow-throated
Warbler (never), Veery (0,0,0,1,0,1), Eastern Kingbird (0,0,1,1,0,0) and
Barn Swallow (14,3,3,11,6,21).

GRACKLES can be unaccountably scarce.  Common:  0,275,90,2,9,500.
Boat-tailed:  0,0,2,18,14,0.

House Finch:  0,3,0,0,6,1.  Still scarce in the south part of this county.


Species yet to be seen:  Common Loon, Least Bittern, American
Oystercatcher, American Woodcock, Ruddy Turnstone, Bonaparte's Gull, Black
Tern, Barn Owl, Common Nighthawk, Chuck-will's-widow, White-breasted
Nuthatch, Brown Creeper, Sedge Wren, Archaeopteryx, Wood Thrush (!), Canada
Warbler, Yellow-breasted Chat, Grasshopper Sparrow, Saltmarsh Sharp-tailed
Sparrow, White-throated Sparrow.

Fall species (all only seen 1X) never seen on the 70 Dorchester May counts:
 Eared Grebe, American Golden-Plover, Yellow-bellied Sapsucker, Least
Flycatcher, Winter Wren, Yellow-headed Blackbird and Lincoln's Sparrow.

Every day is different.  So is every season, every year.  That's one reason
we keep coming back, isn't it?

My thanks to those who have assisted me on these counts:  George Armistead,
Jon Beadell, Carol Erwin, Carl Perry, Les Roslund, Paul Spitzer, and Levin
Willey.  My thanks to Chuck Stirrat for providing a copy of the 2001 count
that I had misfiled.
