THE BIRDING COMMUNITY E-BULLETIN
JANUARY 2006
The Birding Community E-bulletin is distributed as a service for 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 past E-bulletins on the website of the National Wildlife Refuge Association (NWRA):

RARITY FOCUS
This month, we had our choice of two rarities, both fascinating
waterfowl: Falcated Duck in Oregon and Baikal Teal in California.
We'll go with Falcated Duck for now, if only because it was found
first.
A male Falcated Duck appeared on 18 November at the Premier RV Resort
north of Eugene, Oregon. This is almost certainly the same bird that
was seen at this same location last winter. That bird was seen from 16
January into April 2005 - (though not every day) and was recently
accepted by the Oregon Rare Birds Records Committee as a bona fide
vagrant.
Falcated Ducks (formerly know as Falcated Teal) normally breed in
eastern Siberia southward to Mongolia and Japan. They normally winter
from Japan south to Korea, less frequently westward to Iran and
southward to Thailand. In North America, the species is casual in
Alaska (e.g., Pribilof and Aleutian Islands), with reliable reports
also in British Columbia south to central California.
The drake in Oregon frequents the wastewater ponds on the south side
of the RV resort.
Visitors must check in at the RV resort office before looking for the
bird. The RV managers are friendly, and they welcome responsible
birders. They usually direct birders to proceed past the
laundry/restroom area and continue beyond a few campsites to a parking
spot next to the northern-most wastewater treatment pond.

CHRISTMAS BIRD COUNTS
'Tis the season!
It started in 1900 when Frank Chapman introduced the concept of a
Christmas Bird Count as an alternative to a Christmas Bird Shoot (also
called a Side Hunt). Why not count and appreciate birds instead of
hunting them indiscriminately? The effort caught on, and in a few
years the pioneers of the Audubon movement institutionalized the
practice as their own.
Now let us fast forward to the next century. The 106th consecutive
CBC, a massive effort in citizen science effort is currently upon us.
Last year there were more than 2,000 CBC circles and more than 56,000
participants, who counted and reported birds from throughout the U.S.,
Canada, the Caribbean, Latin America, Guam, and the Northern Marianas.
We encourage you to find a Christmas Bird Count near where you live
and participate. This year's CBC period extends from 14 December
2005 to 5 January 2006.
LONG-RANGE SAW-WHET
The fall of 2005 witnessed a robust flight of Northern Saw-whet Owls
in eastern Massachusetts. Norman Smith, veteran owl bander and
director of Mass Audubon's Blue Hills Trailside Museum, banded
over 300 saw-whets during October and November at just two Bay State
sites. Most notably he captured a saw-whet owl bearing a band that was
applied by G. Frye at a site near Choteau, Montana, of 27 September
2003! This banding recovery is thought to represent the longest
confirmed west to east distance ever recorded for a migrant Northern
Saw-whet Owl.
AVITOURISM AND BIRDING SUMMARY
For a summary of works on avitourism and related subjects - mostly
recent Canadian and US articles, including some important pieces
dating back to the late 1970s -
see the article posted by Agnes Nowaczek, PhD Candidate from the
Department of Recreation and Leisure Studies, University of Waterloo,
Ontario. Almost 100 works are summarized, covering a variety of
National Parks, Provincial Parks, and National Wildlife Refuges, along
motivational and economic background information.
APPEAL FOR COLUMBIAN SHARP-TAILED
GROUSE
A coalition of environmental groups indicated in late November that
they will sue the U.S. Fish and Wildlife Service (USFWS) over the
agency's failure to respond to a year-old petition seeking federal
protection for the "Columbian" race of the Sharp-tailed
Grouse under the Endangered Species Act.
Previously the Forest Guardians, Sagebrush Sea Campaign and Oregon
Natural Desert Association have argued that this bird is sliding
toward extinction. The groups first sought federal protection for the
grouse in 1995, but the USFWS declined to add the species to the
Endangered Species List on the grounds that while the grouse had
disappeared from much of its range, it still persisted in two large
"metapopulations" in Idaho and Colorado. A 2004 petition
marked the groups' second attempt to win protection for the bird.
But the new petition has also languished, while the grouse continue to
decline.
The "Columbian" Sharp-tailed Grouse was once so common
throughout the Interior West - from eastern Oregon and Washington to
Wyoming and Colorado - that early pioneers supposedly wrote of
"skies darkened by flocks of thousands of birds." Today,
less than 60,000 grouse are said to remain, and the bird has all but
disappeared from about 90 percent of its historic range, today
persisting primarily in small, isolated populations in Colorado,
Idaho, Nevada, Utah, Washington, and Wyoming.
The bird has benefited from the Farm Bill's Conservation Reserve
Program (CRP), which protects wildlife habitat by paying farmers and
ranchers to set aside environmentally sensitive lands. But the grouse
has continued to decline, reportedly partly due to changes in the CRP
program that allow emergency livestock grazing during drought.
In its 2000 decision against listing the "Columbian"
Sharp-tailed Grouse, the USFWS acknowledged that most of the small,
isolated populations "will likely be extirpated within a decade
or two," but said "the available information indicates that
the subspecies' metapopulations are relatively secure."
GUNNISON SAGE-GROUSE TO BE
CONSIDERED FOR LISTING
While there are continuing efforts to push USFWS to list the
"Columbian" Sharp-tailed Grouse, similar efforts have
succeeded in convincing the Service to review the status of the
Gunnison Sage-Grouse. Under a settlement with environmental groups
announced in late November, the USFWS has agreed to consider the
Gunnison Sage-Grouse, which is only found in Colorado and Utah, for
protection under the Endangered Species Act. The Service will make a
decision on whether to list the species, which has been a candidate
for listing since 2000, by 31 March 2006.
BROWN PELICAN: SAFE YET?
Also in the area of birds covered or not covered under the Endangered
Species Act (ESA), in mid-December the Endangered Species Recovery
Council (ESRC), submitted a formal petition to remove (delist) the
California Brown Pelican (Pelecanus occidentalis californicus) from
coverage under the federal ESA and from the list of species covered by
the state's California Endangered Species Act. The case was made
that this subspecies represents an ESA success story and that it
should be removed entirely (delisted) from both federal and state
lists (not be merely down-listed from Endangered to Threatened).
The Council indicated that "on the basis of evidence amassed
during recent years, no reasonable assessment of the status of this
subspecies would lead to a conclusion that it is currently in danger
of extinction, or that it is likely to be in danger of extinction
within the foreseeable future." California Brown Pelicans have an
estimated population of 200,000 birds.
The Brown Pelican - eastern and western subspecies - had suffered
devastating declines throughout its range during the 1950s and 1960s.
The species was listed as endangered in October, 1970. With the
banning of DDT in 1972, the tide stared to turn, if only slowly.
(Other species such as Bald Eagle, Osprey, and Peregrine experienced
similar downturns and similar reversals, although certainly not at the
same rates.) In the 1980s, other populations of Brown Pelican were
delisted. Only the California subspecies and populations breeding in
Louisiana and Texas are currently covered under the ESA.
NEW JOINT VENTURE WEBSITE
Yet another bird habitat Joint Venture has launched a website. The
Atlantic Coast Joint Venture has a site which offers partners and the
conservation community a comprehensive overview of ACJV activity.
There are also links to conservation plans and initiatives, a summary
of partner projects and accomplishments, information on resources, and
links to the ACJV Electronic newsletter and upcoming events.
STOPOVER AWARENESS
In the most recent issue of THE AUK (October 05), David Mehlman and
seven co-authors cover the issue of "Conserving Stopover Sites
for Forest-dwelling Migratory Landbirds" in a thought-provoking
way and in a fashion that is also fully understandable to the general
birding public.
The article categorizes three types of migratory landbird stopover
sites - "fire escapes," "convenience stores," and
"full-service hotels." The article goes on to outline how an
appreciation of these site distinctions, along with their identity and
management, can actually advance modern bird-conservation planning.
The article is not currently available for free, but there is an
earlier version (from 2002) of the concept available
here.
The published version in THE AUK is probably a bit stronger, thanks to
the work of the lead authors and additional work done since 2002.
BIRD FLU: VECTORS OR VICTIMS?
As 2005 comes to a close and we start a new year, millions of wild
birds have arrived at their wintering destinations across Asia,
Africa, Europe, and the Americas. Fortunately they have accomplished
this without the widely predicted outbreaks of H5N1 bird flu that some
experts feared might be associated with their migration.
"The most obvious explanation is that migrating wild birds are
not spreading the disease," said Michael Rands, Director and
Chief Executive of BirdLife International.
While migratory wild birds have been blamed for spreading bird flu
westward from Asia, there has been no spread back eastward, nor to
South Asia and Africa this autumn. Although outbreaks might have been
expected to occur along regular migratory flyways for Asian birds,
such as in the Philippines, Taiwan, and Australia, flu outbreaks have
not been recorded. The limited outbreaks in Eastern Europe are on
southerly migration routes but are just as likely to be caused by
other vectors, such as the import of poultry or poultry products.
"The hypothesis that wild birds are to blame is simply far from
proven," said Dr Rands. "Wild birds occasionally come into
contact with infected poultry and die: they are the victims not
vectors of H5N1 bird flu."
Better biosecurity is key to halting the spread of bird flu. In
particular, BirdLife has been urging governments and other relevant
agencies to concentrate their control and detection efforts on the
poultry and cage-bird trades, banning the movement of poultry and
poultry products from infected areas, and restricting the
international movement of captive birds.
Domestic bird waste is widely used as food and fertilizer in fish
farming and in agriculture, and infected poultry are known to excrete
virus particles in their feces. The use of untreated chicken feces in
fish farming was recently described by the United Nation's Food
and Agriculture Organization as a "high risk production
practice." Russian fish farms have begun using chicken feces as
fish farm fertilizer, and this practice is also employed in Eastern
Europe on agricultural land. The Government of Vietnam has warned its
population against the risk of dumping tons of chicken feces into
rivers and lakes as fish food. One boy in Vietnam has already died of
bird flu after swimming in a river where infected chicken carcasses
were discarded, and in October Mute Swans similarly died at fish farms
in Croatia and Romania.
At the same time, Vietnam has reportedly begun to cull wild birds in
Ho Chi Minh City. Juan Lubroth, an FAO officer in charge of infectious
animal diseases, said that culling wild birds is likely to be
ineffective.
In contrast, implementing measures to regulate the movement of poultry
and poultry feces are proven to work. "For example," said
Dr. Rands, "Malaysia and South Korea both experienced bird flu
outbreaks through importing infected poultry products, but stamped the
disease out and have remained disease free through improved
biosecurity. In the meantime, hundreds of thousands of waterbirds have
arrived to winter inSouth Korea, and many migrant waders have
successfully passed through Malaysia."
Because the virus has the capacity to mutate, it is still essential to
monitor wild bird populations to look for any evidence of new flu
strains arising.
CHAN ROBBINS RETIRES
In 1945, the USFWS hired a Chandler S. Robbins as a junior biologist.
The young Robbins had started birding in 1930 at the age of 12 while
living in Massachusetts, and working for the Service seemed like a
natural for the enthusiastic Robbins.
During his early days of research and exploration in the Service and
at the Patuxent Wildlife Research Center in Maryland, he coauthored
(with Robert Stewart) a fine state bird book, THE BIRDS OF MAYLAND AND
THE DISTRICT OF COMUMBIA (1958), setting a high standard for similar
volumes elsewhere. At the same time, he was instrumental in helping to
establish the Maryland Ornithological Society, then in its early years
of existence.
His work at the USFWS included a 14-year stint (1961-1974) as Chief of
the Migratory Nongame Bird Studies Section. From the Patuxent banding
office, he conducted population studies of doves, snipe, hawks, and
songbirds, particularly focusing on the impact of pesticides,
especially DDT. In response to the DDT concern, he launched the
Breeding Bird Survey (BBS), surely one of his finest accomplishments.
Since initiating the BBS, a roadside bird survey first tested in
Maryland and Delaware in 1965, this program has become one of North
America's most valuable and longstanding avian monitoring schemes.
In 1968 approximately 500 BBS routes were run in the eastern U.S. the
first year; today, over 3,000 routes are conducted.
Robbins' pioneer GUIDE TO FIELD IDENTIFICATION: BIRDS OF NORTH
AMERICA (1966), coauthored with Bertel Bruun and Herbert Zim, has been
described as a "triumph of form and substance."
Chan served as a technical editor of AUDUBON FIELD NOTES (now NORTH
AMERICAN BIRDS) from 1952 to 1989, and he remains, since 1948, editor
of the quarterly journal, MARYLAND BIRDLIFE.
From albatrosses on Midway Island to wintering songbirds in Puerto
Rico, Chan has made major contributions to the appreciation and
understanding of birdlife. A USGS website dedicated to Chan's
contribution summarizes his work: "During these 60 years, Chan,
through his books and articles, his innovative methods for measuring
bird population changes, his leadership in bringing together scientist
and amateur, and his own meticulous field work, has embodied all the
best elements of a public servant."

conservation, click here.
A NEW YEAR'S RESOLUTION?
Very soon, we'll be thinking of those usual resolutions for the
New Year. We suggest a simple look back to the harsh reality of 2005
for the source of such a resolution. The source is a seven-letter
word: K-A-T-R-I-N-A.
The aftermath of Katrina resulted in more than 1,000 people killed,
hundreds of thousands left without homes or much of a safety-net, and
the continued loss of potentially protective wetlands, wetlands which
might have made a difference to thousands of people if they had been
healthy and in place. With the national effort to constrain the
Mississippi, beginning in earnest in the late 1920s, some 1,900 square
miles of marshland - an area the size of Delaware - have been lost.
Louisiana marshland the size of a football field washes away every 45
minutes.
We are describing the nursery-ground for many fishes, oysters, crabs,
and shrimp, the wintering area for as many as 3 million waterfowl, the
nesting area for countless egrets and herons, and a defensive zone for
as many as 3 million people still remaining in jeopardy. On the human
and "practical"side of the equation, the Louisiana
Department of Natural Resources claims that every two miles of marsh
can equal almost a foot of flood protection for New Orleans.
Perhaps Katrina and the loss of wetlands can serve as an example for
your New Year's resolution. Consider doing something to assist the
restoration of wetlands and wildlife, as well as helping the human
inhabitants of the Gulf Coast.
