THE BIRDING COMMUNITY E-BULLETIN
August 2006
This Birding Community E-bulletin is being distributed through the
generous support of Steiner Optics as a service to active and
concerned birders, those dedicated to the joys of birding and the
protection of birds and their habitats. You can access an archive of
our past E-bulletins on the website of the National Wildlife Refuge
Association (NWRA): http://www.refugenet.org/birding/birding5.html and
on the birding pages for Steiner Optics http://www.steiner-birding.com/bulletin.html
RARITY FOCUS
On 17 July, a Black-tailed Godwit was found at the Parker River
National Wildlife Refuge (Plum Island) in Massachusetts. The godwit
was in marsh habitat just south of parking lot 3, south of the
well-known birding spot known as the Salt Pannes. Hundreds of
observers had an opportunity to view the godwit until its departure on
29 July.
This large shorebird, a fairly common breeder from Iceland to Russia,
is a rare, but regular, spring migrant in western Alaska, but its
occurrence on the Atlantic coast of North America is far rarer. (See
your National Geographic guide on page 168-169 or "big"
Sibley on page 176.) There are only three previous records for
Massachusetts, the first going back to 1967. More than a score of East
Coast records show a cluster in the Northeastern U.S. and in Atlantic
Canada, but there are also confirmed records for North Carolina, South
Carolina, Florida, Louisiana, and elsewhere.
East Coast records are generally thought to pertain to the race
"islandica" that breeds in Iceland; however, the different
subspecies are sufficiently similar that they cannot always be
distinguished with certainty. At least one experienced European
observer actually expressed the opinion the Massachusetts godwit was
probably of the nominate race, "limosa." In either case,
photos and details from Phil Brown, who found the bird originally, can
be viewed at ( along with links to other photos from other
photographers): http://www.nebirdsplus.org/BlackTailedGodwit.htm
RARITY-TEASINGS IN THE LRGV
There were also interesting developments - and some disappointments -
in the Lower Rio Grande Valley (LRGV) of Texas last month. On 8 July a
Green-breasted Mango, a relatively large Mexican hummingbird, was
observed at the home of Terry Fuller in San Benito, Cameron County.
The next day the juvenile hummingbird was captured, banded, and
released. Although few observers had a chance to see the bird, its
occurrence was adequately documented.
This species normally ranges from eastern Mexico to northern South
America. There are approximately 15 documented records of
Green-breasted Mango for Texas, mostly in fall and winter. (Some
readers may remember that we profiled a Green-breasted Mango in the
LRGV as our Rarity of the Month in our October 2004 issue.)
This recent record is additionally interesting because it followed a
report in the Fuller's backyard of a probable Amethyst-throated
Hummingbird (Lampornis amethystinus), only a few days previously, on 4
July. That bird was photographed, and although the photographs are
somewhat fuzzy and distant, they may still be adequate to document
this potential first record north of Mexico.
Unfortunately, a continued vigil for additional views of both
hummingbirds has been unsuccessful
At the same time, also in the LRGV, there were two sightings, perhaps
three, of a possible Mottled Owl at the Frontera Audubon property in
Weslaco. The first sighting occurred on 5 July, the second on 11 July.
If accepted, this would be the first record of a live Mottled Owl in
North America. (The only other record was of a bird found dead in the
LRGV in 1983.)
We mention these birds, not because they were seen only by a few
observers - with accompanying disappointment - but because they
illustrate the unknown possibilities and surprises which still await
diligent field observers willing to look for birds in out of the way
places during the "off" season. Indeed, it was not very long
ago that visiting birders would avoid the LRGV in the summer. Everyone
"knew" that there were no special birds around at that
season, and, besides, it was far too hot to look for them!
LAPWING QUANDARY
Also in the realm of surprises and discovery, we present the following
report.
In late May, at St. Marks National Wildlife Refuge in Florida (Wakulla
County), Tom Curtis found a Southern Lapwing (Vanuellus chilensis) at
Mounds Pool 3. Although this species is not on the "official
list" of birds for North America, there are multiple records for
the species in Florida, dating back to the late 1950s, some of which
have been known escapees. The lapwing at St. Marks NWR was observed by
multiple birders for at least three weeks.
Since the Southern Lapwing is native to most of South America
regularly ranging northward to Colombia, Venezuela, and Trinidad, most
birders dismissed the Florida report, as yet another "escaped
bird." The only North American field guide that pictures the
species is the Eastern Peterson (2002) on page 328-9, on a plate with
other "Exotics: Introduced birds and escapes."
But could the species be a legitimate vagrant to the U.S.?
Consider the following:
* Southern Lapwings have recently undergone a notable range
expansion and are currently breeding in the southern Caribbean and
as far north as Costa Rica in Central America. Out-of-range
Southern Lapwings have positively been noted in Belize and Mexico.
* The St. Marks NWR bird seemed to be of the subspecies
"cayennensis" (with brownish face tones), the same form
that has expanded recently into Central America and the southern
Caribbean. To review a photo of the St. Marks NWR individual, see:
http://floridabirds-l.50megs.com/
* Conversion of South American forests to use for livestock grazing
may be promoting accompanying increases in Southern Lapwing
populations and range expansion. It has also been suggested that
competition with Cattle Egrets may be driving Southern Lapwings
into new areas.
* Almost all of the previous Florida sightings of Southern Lapwing
over the years have occurred during late spring or early summer.
* The only zoos reporting Southern Lapwings in their collections
within the last five years are in Cincinnati, Philadelphia, Salt
Lake City, and Winnipeg. (Of course, there could also be birds in
"private" collections!)
While very intriguing we may never really know the truth. End of
story.
Or is it?
On 17 Jun and 725 miles north of St. Marks NWR, while working on
Maryland's Breeding Bird Atlas project by boat, Mark L. Hoffman
found a Southern Lapwing in marshes in Worcester County, Maryland. The
bird was observed for 20 minutes and photographed.
The bird could not be found on following days. Details and images can
be found here: http://www.pbase.com/wcbirding/sola
Same bird? Different bird? Escaped bird? True vagrant?
These are all fascinating questions, to which we can only add the
advice: Stay alert out there, and always be attuned to the
possibilities!
BIRDING TRENDS: OUTDOOR INDUSTRY FOUNDATION
There was a fascinating report released in late June by the Outdoor
Industry Foundation which profiled the "2005 American bird
watcher" as having the following characteristics:
* Balanced by gender and marital status
* Just over a third will have children under the age of 18 living
in their household
* Over two-thirds will be over the age of 35 with half over the age
of 45 (mean age 45)
* Equally distributed across regions
* More than 8 out of 10 birders will be Caucasian (similar to
findings for hunting)
* Hiking will be the most popular additional outdoor activity
* Went on bird watching excursions 12 times on average during the
year
* Close to a one-third will limit their activity to only a single
outing during the year
* Only 5 percent will go on 31 or more field trips a year.
Demographically, according to the foundation, the bird watching
population has remained very stable over the years, but there has been
a recent drop in the number of Americans birding and the number of
field trips taken. (2001 had 18.3 million birders taking an average of
31 outings a year; 2005 had 15.6 million birders taking an average of
12 outings per year.)

HOW IMPORTANT IS "SODSAVER"?
A new cycle of grassland conversion is making its way across the
Prairie Pothole heartland of the country, converting ancient
grasslands to commodity cropland. For example, of the 13.8 million
acres of ancient prairie that remains in the eastern Dakotas, the Farm
Service Agency reported that almost 300,000 acres, or 2.2%, were
converted to cropland during 2002-2005. At this rate it won't be
long before a near-endless mix of soybeans, wheat, and canola - with
accompanying patches of sorghum, corn, barley, rye, and even flaxseed
- spreads across the region.
This loss of ancient grassland, of course, is a result of
technological advances and federal farm support. The current commodity
title of the 2002 Farm Bill provides incentives that encourage farmers
to break native sod by substantially reducing the financial risks
associated with such activities. This trend puts into jeopardy many
ducks and shorebirds, as well as many grassland-dependent songbirds,
species that are witnessing a steeper population decline than any
other bird group in North America. Without a plan to halt the loss of
ancient grassland, we risk losing the native prairie, accompanying
wetlands, and their birds.
A proposed "Sodsaver" provision of the expected 2007 Farm
Bill, an action that might eliminate federal subsidy support of any
kind on new cropland put into production through the breaking of
grassland that had no previous cropping history, could be a way to
reverse this trend.
Of course, landowners could still choose to break native prairie if
they so desired, but they would not be able to do it under the
umbrella of a federal farm subsidy if "Sodsaver" is adopted.
(It is important to realize that a "Sodbuster" program has
existed since the 1985 Farm Bill, but this has only applied to land
that is highly eroded, and farmers could develop a plan to circumvent
its coverage. The proposed "Sodsaver" is a far more
inclusive policy.)
An amendment in the upcoming Farm Bill is being promoted in order to
maintain vital bird nesting habitat and would remove incentives for
breaking native sod. In addition to protecting native prairie, such a
provision would, by default, also protect a large percentage of what
prairie wetlands still remain. . Approximately 60% of these
unprotected wetlands are surrounded by native prairie.
Ducks Unlimited, along with a number of other national and regional
conservation organizations, is strongly promoting this new
"Sodsaver" proposal.
IBA NEWS: NORTH CAROLINA, THE HIGHLAND EMPHASIS
The North Carolina Important Bird Area project is moving along, with
participation from all the seven Audubon chapters in the state,
working on the "Adopt an IBA program." This covers 15 IBAs
and potential IBAs. Volunteers are conducting data collection, policy
and conservation work, and educational programs, especially in those
IBAs where a State Parks partnership provides opportunities for
expanded programs.
Of particular interest is the effort in the Highlands Plateau, in the
southern end of the Blue Ridge Mountains, in the westernmost corner of
the state. This area hosts habitat for some of North Carolina's
important "northern" species, such as Blackburnian Warbler,
Golden-crowned Kinglet, and Rose-breasted Grosbeak. The Highlands
effort is intended to focus on specific monitoring of the species in
the forests, mountains, and streamsides of the area with a special
emphasis on building information and accompanying long-range
stewardship.

MULTI-STATE CATS-AND-BIRDS REPORT
The American Bird Conservancy has published a new report, the
first-ever multi-state review of feral and free-ranging cats. It's
a five state review, covering New York, New Jersey, Florida,
California, and Hawaii.
The report analyzes the impact that cats are having on some of
America's most at-risk bird species. The five-state review
clarifies the disturbing threats to species and sub-species already in
trouble, such as Piping Plover, "California" Clapper Rail,
and Hawaiian Petrel. Sites where cats have had particular avian impact
are profiled. The report reviews applicable wildlife protection laws.
Perhaps most disturbingly, the report also highlights the growing
trend of maintaining managed cat colonies.

NEW PLJV FILM
The Playa Lakes Joint Venture (PLJV) released a new film in late June.
The 28-minute film, titled "The Playas - Reflections of Life on
the Plains," illustrates the values of playas to wildlife, water,
and people; threats to the wetlands; and how people are working to
conserve them. The film features sweeping aerial footage of playas,
along with interviews with playa experts, biologists, landowners, and
community leaders throughout the six-state playa region. The playa
region covers parts of NW Texas, W. Oklahoma, E. New Mexico and
Colorado, C. and W. Kansas, and NW Nebraska.
Debbie Slobe, Communications Team Leader for the PLJV, said that the
message of the playa wetlands can be collectively linked to birding,
hunting, and wildlife and natural resource conservation.
The film is now available on DVD or VHS. There is no charge for the
film except for shipping. To obtain a copy or quantity of films,

IVORY-BILLED WOODPECKER REPRIEVE: U.S. DISTRICT COURT
DECISION
Late last month, U.S. District Judge, William R. Wilson, issued a
temporary injunction against a $319-million planned irrigation project
in Arkansas because it could destroy habitat for the Ivory-billed
Woodpecker, a species that may or may not be already extinct.
The U.S. Army Corps of Engineers began building the Grand Prairie
Irrigation Project last year - less than 20 miles from where recent
alleged woodpecker sightings had been reported - in an effort to draw
water from the White River. The project would take 158 billion gallons
from the river each year. The project was supposedly necessary because
the main aquifer beneath eastern Arkansas's soybean, cotton, and
rice fields is running out of water and could run dry by 2015, thus
causing serious economic hardship.
Conservationists, led by the National Wildlife Federation and the
Arkansas Wildlife Federation, sued the Corps, arguing that the project
to build a pumping station would destroy habitat, killing trees that
could support the woodpeckers, and that the noise from the station
would cause any existing woodpeckers unnecessary stress.
The judge said that for the purposes of the lawsuit, one has to
presume that the woodpecker exists. He further pointed out that
federal agencies might have broken the nation's Endangered Species
Act by not fully studying the risks of the project beforehand.
The Corps has been ordered to reinitiate consultation with the U.S.
Fish and Wildlife Service to determine if the project poses a threat
to the Ivory-billed Woodpecker or its habitat.
However, the ruling may not have any immediate impact on the Grand
Prairie irrigation project anyway, since construction was recently
halted due to lack of funding. Still, new surveys must include
"nest, roost, and active forage surveys within 2.5 miles of any
construction site 'footprint;' identification and inspection
for nesting, roosting, or active foraging in all trees 12 inches or
greater in areas that will be most affected by changes in water level;
and nest, roost, and foraging surveys in the forest areas adjacent to
canals and pipelines."

habitat, see the National Wildlife Refuge Association report on
"Beyond the Boundaries," page 14: http://www.refugenet.org/new-pdf-files/BeyondtheBoundaries.pdf
ALWAYS BE CAREFUL WHERE YOU PARK
You may have missed this important news in early July, so we present
it here for your enlightenment.
Last month's launch of NASA's orbiting space shuttle
"Discovery," was complicated by the discovery of some
whitish splotches on the shuttle's black-colored right wing after
the launch. NASA officials stated that these appeared to be "bird
droppings."
If correct, this means that these bird droppings withstood (1) intense
and regular Florida thunderstorms, (2) a powerful launch during which
300,000 gallons of water were sprayed at the shuttle's main
engines, and (3) a thrust upward through Earth's atmosphere.
(During the launch, Discovery went from 0 to 17,500 miles per hour in
under 9 minutes.)
This example offers new appreciation for the
"out-of-this-world" durability of bird droppings.
Apparently, despite a reentry temperature of as much as 3,000 degrees
Fahrenheit, the bird poop made it all the way back from orbit on 17
July, albeit a bit charred!
