THE BIRDING COMMUNITY E-BULLETIN
May 2011
This Birding Community E-bulletin is being distributed to active and
concerned birders, those dedicated to the joys of birding and the
protection of birds and their habitats.
This issue is sponsored by NATIONAL GEOGRAPHIC and the wonderful bird
and birding books they make available: www.shopng.com/birdbooks

RARITY FOCUS
A fascinating gull was discovered on 9 April at Kalmus Beach in
Hyannis, on Cape Cod, Massachusetts by Keelin Miller. Though it was
first thought to be a Lesser Black-backed Gull, things didn't seem
"quite right" for that identification. The gull, which was
an adult in breeding plumage, seemed larger, chubbier, and
paler-mantled than a typical Lesser Black-backed Gull. The
identification problem was compounded by the absence of any obvious
Lesser Black-backed Gulls for comparison. Following critical photo
examination and considerable discussion among birders, opinion leaned
toward the conclusion that the gull was actually a Yellow-legged Gull,
a casual visitor from Europe. Although the possibility of the gull
being a hybrid Lesser Black-backed X Herring was not completely
discounted, opinion of most experts seemed to favor Yellow-legged Gull
as the most probable identity.
The Yellow-legged Gull is a vagrant from Europe, once considered a
European form of the Herring Gull. The species breeds on islands in
the eastern Atlantic Ocean, in western Europe, and in the
Mediterranean to central Asia. It winters south to the Persian Gulf
and Indian subcontinent. If you are unfamiliar with the species,
consult a European field guide, the National Geographic Guide (fifth
edition) on pp. 206-207, the "big" Sibley on page 207, or
the new Stokes guide on pp. 320-321.
Yellow-legged Gulls are rare but annual winter visitors to parts of
Atlantic Canada (e.g., St. John's, Newfoundland), but they are
even rarer anywhere in the U.S. There are now convincing reports for a
number of locations, including Maryland, Massachusetts, North
Carolina, Texas, Virginia, and Washington, DC.
The gull was very cooperative in the area of Kalmus Beach until the
morning of 18 April, when it was last reported. To see photos of the
bird taken by Peter Trimble, see:

MORE FINDINGS ON LEAD AND CONDORS
There are approximately 200 California Condors in the wild today
(California 97, Arizona 73 and Baja California 20), and some of these
belong to "experimental populations." Despite serious
management efforts to reduce California Condors to the risk of lead
exposure, they continue to be accidentally poisoned on a regular
basis.
In March, findings presented at the annual meeting of the Society of
Toxicology held in Washington DC, confirmed the fact that lead
continues to be a primary factor limiting the survival of California
Condors in the wild. In a cooperative study conducted by scientists
from the University of California at Santa Cruz (UCSC), the University
of Wyoming, the U.S. Fish and Wildlife Service, and the National Park
Service, it was concluded that ammunition was the most plausible
source of this lead exposure.
This study examined 70 blood samples collected from 49 free-flying
condors in California. The blood analysis was compared to an
examination of 71 lead-based ammunition samples. Employing a technique
called lead isotopic composition analysis, the researchers identified
the chemical fingerprint of the lead found in condor blood and
concluded that about 90 percent of free-flying condors have been
exposed to lead-based ammunition.
"For over 100 years we have known that condors can be poisoned
when they eat carcasses shot with lead bullets, although facets of the
hunting lobby remain unconvinced," said Myra Finkelstein of USCS.
"Our findings help refute some of their claims."
Not only did the lead in condor blood match ammunition samples, the
study also revealed that toxic lead has a larger impact than
previously thought. For example, even at low levels, lead inhibits an
important enzyme responsible for making red blood cells in condors.
Even in California Condors with low lead levels in their blood, the
enzyme's activity was inhibited by 60 percent.
Large-game carcasses, such as mortally wounded deer and elk which
evade hunters to die in the wild, and gut-piles left when an animal is
cleaned in the field (often with splayed tiny lead particles deposited
when a bullet hits the animal) can leave lead behind. These bullets or
tiny lead fragments may then be consumed by the condors.
Other findings also point to a persistent lead problem for condors.
For example, in 2009 almost half of the condors monitored at one
California release site (i.e., Pinnacles National Monument) received
clinical treatment for lead poisoning.
Hopefully, these findings may encourage broader concern and stronger
compliance with a fairly recent lead-bullet ban in a broad zone across
California within areas covering the condor's historic range. Gov.
Arnold Schwarzenegger signed the Ridley-Tree Condor Preservation Act
(AB 821) into law in October, 2007. The bill went into effect on 1
July 2008, banning the use of lead bullets within condor territory,
however it seems to be poorly enforced, reportedly due to a lack of
funding. See the November 2007 E-bulletin for more details on AB 821:

POSSIBLE BIRD SEED CONTAMINATION: NOT TO WORRY
Last month, the American Bird Conservancy (ABC) announced the results
of a study to test the safety of popular wild bird seed. The
laboratory analysis showed that all the tested seed was either free
from pesticides or fell below levels that would threaten bird health.
The study involved samples taken from four different supply sources
across the country: Home Depot, Lowe's, Target, and Walmart. The
bird seed was randomly purchased from those stores and then tested at
the California Food Safety Laboratory at the University of California,
Davis. The laboratory conducted detailed analyses over many months.
The investigation was specifically checking for harmful pesticides,
such as organophosphate and carbamate insecticides.
"We wanted to make sure that the isolated problem cases in the
past were indeed behind us, and as far as we can tell, that is the
case. The bird seed producers seem to be doing a good job of producing
a safe product," said Dr. Moira McKernan, Director of ABC's
Pesticides and Birds Program.

THAT ALBATROSS NESTING ON MIDWAY
We reported last month that 110,000 Laysan and Black-footed Albatross
chicks at Midway NWR perished as a result of the tsunami in early
March which were combined with two severe winter storms in January and
February. At least 2,000 adults were also killed.
During this time, the status of Midway's one pair of rare
Short-tailed Albatrosses raising a chick was unknown. It turns out
that as a result of the tsunami, the chick had been washed
approximately 100 feet from its nest, but was later successfully
returned by refuge staff. However, the chick's parents were not to
be seen in the aftermath of the tsunami. It was hoped that the adults
were simply spending an extended period at sea before returning to
Midway to feed their youngster. Finally, and with considerable relief
on the part of officials, the male Short-tailed Albatross was seen
feeding its chick on 23 April.
Here are our reports from January:

FEDERAL CONSERVATION & BIRD SPENDING RESULTS FOR
FY11
The federal budget battle and bird conservation were discussed in the
E-bulletion in March and April: www.refugenet.org/birding/marsbc11.html#TOC05
www.refugenet.org/birding/aprsbc11.html#TOC06
The final FY2011 spending bill, enacted on 15 April, was devastating
to bird-related conservation issues, but fortunately less drastic than
in earlier proposed versions (e.g., H.R. 1).
Essential programs, such as the funding for the North American Wetland
Conservation Act (NAWCA), the State Wildlife Grants, and the Land and
Water Conservation Fund (LWCF) were initially recommended for
elimination, or drastic reductions, in the original House-passed
H.R.1. Instead, they were "only" drastically slashed, with
some of these and similar programs receiving cuts of one-third the
2010 levels.
Consider these numbers:
The North American Wetlands Conservation Fund ended up at $37.5
million, down 21 percent from FY10 ($47.65 million), but up from $0,
proposed in the original H.R. 1.
The State and Tribal Wildlife Grants program is to be funded at $62
million - a reduction of 31 percent from 2010 (i.e., $90 million) and
the lowest level for the program in its 10-year history. This is up
from $0 proposed in H.R. 1.
Funding for LWCF was put at $301 million - a 33-percent reduction
from last year, but up from $244 million proposed in H.R. 1.
The Neotropical Migratory Bird Conservation Act was reduced to $4
million, a reduction of 20 percent from $5 million last year.
The Wetlands Reserve Program, a crucial Farm Bill element, is reduced
$119 million from FY10.
EQIP, the Environmental Quality Incentives Program, is reduced $80
million from last year.
The Conservation Stewardship Program, another USDA effort, is reduced
$39 million.
At the agency level, the Natural Resources Conservation Service
(NRCS) will have to function with a $118-million drop in its overall
operations budget.
Most of the anti-conservation riders originally attached to H.R. 1
were removed from the final bill. This includes one that would have
undercut the Environmental Protection Agency's efforts to restore
protections for certain wetlands and streams. Still, the final budget
bill includes language that would undermine EPA's efforts to
reduce pollution from mountaintop coal mining and mercury emissions
from power plants; stop the BLM's new Wild Lands Policy (issued in
late December and clarifying how BLM lands with wilderness
characteristics are to be inventoried, described, and managed); and
remove gray wolves from Endangered Species protection in a number of
states.
With the battle over FY2011 ended, deep concern mounts over how
drastic the budget cuts might be for FY 2012.

IBA NEWS: SKAGGS ISLAND SECURED FOR BAY-AREA
CONSERVATION
For over 50 years, Skaggs Island was a secret and secure naval base,
involved in communications and intelligence functions for the U.S.
Navy and other federal intelligence organizations. Skaggs Island is
located 40 miles northeast of San Francisco, California, near the
shore of San Pablo Bay in Sonoma County.
The 3,310-acre site was purchased by the Navy in 1941 and closed in
1993, although high-frequency antennas continued to be used for some
time after the official closing.
The island is also one of the largest diked wetlands in the North Bay.
The combination of an abandoned federal facility and a complex of
wetlands and associated other habitats made Skaggs Island an ideal
candidate for conservation. In 2008, Congresswoman Lynn Woolsey (D-CA)
intervened with legislation when the Navy and the USFWS failed to
agree on transfer conditions and when it appeared that the property
might end up going to bid for alternate uses. As a result, the
property was able to be transferred from the Navy to the USFWS to
enlarge the nearby San Pablo Bay National Wildlife Refuge, part of a
larger, already existing IBA site.
In 2010, the U.S. Navy demolished more than 100 structures and
completed an extensive environmental cleanup of the site, and in late
March of this year the final documents were signed to transfer Skaggs
Island to the Service. The site will increase the size of the
13,000-acre San Pablo Bay National Wildlife Refuge by a quarter, and
will add a much-needed haven in the North Bay for birds and other
wildlife. Skaggs Island is essential to San Pablo Bay wetlands
restoration because it is the center of the hydrology through which
other restoration projects, totaling over 30,000 acres, can be
connected. It will link San Pablo Bay National Wildlife Refuge with
the Napa Sonoma Marshes State Wildlife Area and numerous other natural
marshes and wetland restoration sites currently managed by the
California Department of Fish and Game and the Sonoma Land Trust.
"Skaggs Island is a missing piece of the puzzle for restoration
in the North Bay, and we're excited to see it become part the
refuge," said Don Brubaker, manager of the San Pablo Bay National
Wildlife Refuge.
The San Pablo Bay National Wildlife Refuge itself was created in 1974
to protect migratory birds, wetland habitat, and certain birds, such
as the "California" Clapper Rail and what may be the largest
population of wintering Canvasbacks on the West Coast. You can find
details on the San Pablo Bay wetlands IBA here: http://iba.audubon.org/iba/viewSiteProfile.do?siteId=155&navSite=stat

HELPING PARROTS IN THE RIO GRANDE VALLEY
The Lower Rio Grande Valley of Texas has the only accepted established
and countable wild populations of Red-crowned Parrots and Green
Parakeets in the U.S. (with some outlier released populations in
Florida and California). With winter freezes, increasing development,
and new landscape practices in South Texas, the parrots and parakeets
are losing some of their roosting, feeding, and, nesting sites which
tend to be in cavities in dead palm trees.
A plan, starting in Harlingen and led by the RGV Birding Festival and
the Arroyo Colorado Audubon Society, is aimed at increasing nesting
sites, promoting a local ordinance protecting the birds, and
conducting surveys to better understand distribution, population size,
and behavior. The local ordinance is currently being drafted, the
survey implemented, and novel nesting cavities created.

project, check: www.rgvbf.org/2011/04/the-great-palm-raising-saga/
TIP OF THE MONTH: DON'T BE AFRAID OF A RAINY DAY!
At this time of year, when spring migration is foremost in the mind of
many birders, don't be disappointed if there's the prospect of
rain in the forecast. While it's true that rainy weather can put a
damper on certain outdoor activities, it's also a fact that a
light drizzle or misty conditions, especially when combined with warm
temperatures, can produce some outstanding birding opportunities.
Since most songbirds tend to migrate at night, foggy, misty, or light
rain tends to force migrants down from their overhead nocturnal
journeys, occasionally in spectacular numbers. So rather than postpone
a day's birding because of less than propitious conditions, go
birding anyway. You may be delightfully surprised by what you see and
how much you find, even if you get wet while searching.
WHSRN: A QUARTER CENTURY OF IDENTIFYING VITAL SITES
During the mid-1980s, observers across the Americas were beginning to
record serious population declines in many shorebird populations. As a
result, a conservation initiative called the Western Hemisphere
Shorebird Reserve Network (WHSRN) was launched in 1986. The first
officially designated WHRSN site in the U.S. was Delaware Bay. Since
then, WHSRN has proceeded with the simple strategy of trying to
identify and protect key shorebird habitats throughout the Americas.
The WHSRN program has currently identified 84 critically important
sites in 13 countries, extending from Alaska in the north to Tierra
del Fuego in southern South America. For a complete history and
background of WHSRN, see here: www.whsrn.org/about-whsrn/history-background
On 9 May, WHSRN will celebrate the 25th anniversary of its first site
of Hemispheric Importance, the Delaware Bay.
With this event in mind, Charles Duncan, Director of WHSRN's
Executive Office, recently remarked, "The Network has increased
awareness about shorebirds and their habitats and cooperation among
agencies and member sites. But on its 25th anniversary we must also
recognize that the habitats and coastlines that shorebirds depend on
are increasingly threatened. Populations of many species are now only
a small fraction of what they were when WHSRN was founded. This
celebration must also mark a recommitment to conserving these
magnificent birds, for their benefit and for ours."
A number of organizations are celebrating the anniversary on the
Delaware Bay, and distinguished guests expected to attend include the
former U.S. House member for Delaware, Michael Castle. Castle was
Delaware's governor at the time Delaware Bay was designated as the
network's first site. Henry M. Paulson, Jr., ardent
conservationist and the 74th Secretary of the U.S. Treasury, will
deliver the keynote address at the event.
WHIMBREL TRAVELS: "HOPE"
Also on the subject of shorebirds and their migrations, it may be
particularly instructive to follow the travels of just a single
Whimbrel, a bird nicknamed "Hope."
Hope is a female Whimbrel that was captured in Virginia on the
southern Delmarva Peninsula on 19 May 2009. There, she was banded and
fitted with a satellite transmitter. Since then, Hope has logged more
than 21,000 miles (33,000 kilometers), flying between a remote
Canadian breeding territory on the MacKenzie River (an IBA site, by
the way) near Alaska and a comfortable winter territory on St. Croix
in the U.S. Virgin Islands!
Last month, on 8 April, Hope returned to Virginia following a 75-hour,
1,850-mile (2,900 kilometer) flight over the Atlantic Ocean. For more
details and to see a fascinating route map showing Hope's
journeys, see here: www.fws.gov/northeast/news/2011/041411.html
BOOK NOTES: BIRDING UPSIDE-DOWN
All the ads say that THE CROSSLEY ID GUIDE will turn birding
upside-down. It may do that for you, or perhaps it won't.
Regardless, this new book will get you to take a thoughtful look at a
unique way to present bird identification to the public. This guide,
currently only to Eastern birds, consists of 640 photographic scenes,
each created with superimposed individual bird photos, with a
different scene for each species. The bird images were lifted and
enhanced from about 10,000 photographs (all taken by author, Richard
Crossley), and creatively presented in their most likely to be
encountered habitats. For example, most gulls are shown on shorelines,
storm-petrels at sea, swifts in the air, meadowlarks in short grasses,
and Cattle Egrets in fields following cattle. The presentation is both
novel and very helpful, verifying the old saying that a good picture
is worth a thousand words. Most plumage variations – sex, age,
and season – are shown, and shown well. And to keep the reader
sharp and guessing, some are unlabeled on purpose.
Some readers may liken the page layouts to musuem-oriented dioramas;
others may feel the need to slip on a set of 3-D glasses; and still
others will find each page simply a delight to behold. You'll have
to see this book to be the judge.
The text and maps are good, but most readers will probably buy this
book for the images, not for its other features.
The mere size and weight of the book – even bigger and heftier
than the popular "Big Sibley," and weighing in at 3 pounds,
9 ounces – will make carrying it in the field bit of a chore.In
fairness, however, a book with such a unique approach couldn't be
any smaller or much lighter in weight. Our guess, however, is that
Richard Crossley's new guide will certainly travel into the field,
at least finding a place on the car seat or in the glove box on many a
trip.
FEDERAL JUNIOR DUCK STAMP CONTEST
Abraham Hunter, a 17-year-old student from Vienna, Illinois, won the
Federal Junior Duck Stamp Contest held on 15 April. Hunter's
winning picture was a striking image of a pair of Ring-necked Ducks.
The contest was held at the John Heinz National Wildlife Refuge at
Tinicum, within a mile of the Philadelphia International Airport.
Several hundred school students and local Philadelphia residents were
in attendance for the contest.
