RARITY
FOCUS
This month's feature rarity is a wonder-wader, a bird that's delighted
many viewers through the month of July.
A long-legged wading bird first seen in mid-June at Stephenville Crossing,
southeastern Newfoundland, was initially identified as a Little
Blue Heron. Eventually, however, Newfoundland birders took a closer
look and determined that the bird was actually a Western Reef-Heron,
a species that has only occurred once before in North America, on
Nantucket Island, Massachusetts, in 1983. That bird remained from
late April to mid- September, where it was studied and photographed
by hundreds of observers.
The normal range of the Western Reef-Heron's nominate race is western
Africa from Mauritania to Nigeria, casually north to the Azores,
Cape Verde Islands, and Spain. A second population occurs from the
Persian Gulf to western India. Interestingly enough, however, this
species is also appearing with increasing frequency in the Caribbean
and if not already breeding there, may soon do so. In many respects,
Western Reef-Heron appears to be shadowing the vagrancy pattern
exhibited by Little Egret, a species which some authorities consider
to be conspecific.
Not surprisingly, perhaps, the bird was associating with a Little Egret,
another Old World rarity. By late June, both birds were frequenting
a salt marsh and island in the vicinity of nesting terns and gulls
near the crossing, the same area where Black-headed Gulls first
nested in North America in 1977.
This Western Reef-Heron is approximately the same size as the Little
Egret. The overall color of the heron is slate-bluish-gray, except
for a white throat and chin. The bill is dark, and perhaps slightly
longer than that of a Little Egret. The feet are yellow, the legs
dark. (The species is not illustrated in any North American field
guide. For a picture of the Newfoundland Western Reef-Heron in the
company of the Little Egret, see
the image provided by our friends at NARBA, the North American
Rare Bird Alert.
Both the reef-heron and the Little Egret were still present at least
into the last days of July. They were reported most easily seen
at low tide in the morning when they come close to the road to feed.
If these two rarities weren't enough, another bonus bird appeared
in the area, creating a veritable birding rarity trifecta. This
was a Bar-tailed Godwit, another Eurasian species. It continued
in the area until at least 22 July.
[Late-breaking News: We just found out about a mega-rarity, a Hornby's
Storm-Petrel seen off Southern California on 2 August. This would
be a first North American record. More details next month, in our
news for August. In the meantime, you may want to refer to Debi
Shearwater's site.]

NEOTROP ACT MOVEMENT
There were hearings in late June on the reauthorization of the Neotropical
Migratory Bird Conservation Act, with movement in both the Senate
and the House.
Thanks in part to the active support of many bird organizations, the
slightly renamed Neotropical Migratory Bird Conservation Improvement
Act, S. 1410, was unanimously approved by the Senate Environment
and Public Works Committee at a committee session in mid-July. Introduced
by Senators Chafee (R-RI), Clinton (D-NY), Crapo (R- ID), Jeffords
(I-VT), Lautenberg (D-NJ), and Voinovich (R-OH), the bill is very
similar to its House counterpart, H.R. 518. (The Senate version
has some minor improvements, however.) The Senate bill now awaits
consideration by the full Senate.

HIGHEST NUMBER OF KIRTLAND'S WARBLERS
EVER RECORDED
In
last month's E-bulletin, we mentioned the partial returns for the
annual Kirtland's Warbler census, along with a couple birds with
surprising longevity records.
Now
the full census is complete. In mid-July, the Michigan Department
of Natural Resources announced the annual survey results indicating
that the state's population of the federally Endangered Kirtland's
Warbler is increasing.
Biologists,
researchers, and volunteers counted as many as 1,415 singing males
during the 2005 official census period. This count exceeds the 1,348
males observed in 2004, and it represents the largest number of
Kirtland's Warblers recorded since this monitoring program began.
The census was started in 1951 and has been conducted annually since
1971. The lowest numbers of warblers were recorded in 1974 and 1987,
when only 167 singing males were found.
In
addition, three singing males were discovered in Wisconsin this
year.
Cooperation
between the Michigan DNR, U.S. Forest Service, U. S. Fish and Wildlife
Service (USFWS), and the Michigan Department of Military Affairs
in attempting to restore the warblers' nesting habitat has been
heartening.

AGAIN: WHERE ARE THE CHASE LAKE
PELICANS?
For
the second year in a row the USFWS is investigating the deaths of
thousands of young American White Pelicans at Chase Lake National
Wildlife Refuge in central North Dakota. You may remember that thousands
of adult pelicans abruptly left the same location in 2004.
The
pelican colony at the 4,385-acre Chase Lake National Wildlife Refuge
has been the largest in North America, peaking at 35,466 birds in
2000.
It
has been reported that at least 8,000 chicks may have died over
the past few months, said Ken Torkelson, a spokesperson for the
refuge. "The difference is, last year the adults left first," he
said. "This year, the young have died and the adults have no reason
to stick around."
Severe
storms or a disease outbreak may have caused the mass die-off, said
Marsha Sovada, a biologist at the U.S. Geological Survey's Northern
Prairie Wildlife Research Center in Jamestown.
The
USFWS said an inspection of the refuge in mid-July indicated that
only about 500 chicks were left from a nesting period that could
have produced as many as 9,000. All but about 2,000 adults abandoned
the colony, from a population estimated at 18,850 at the end of
May.
Wildlife
officials had hoped the refuge would return to normal after nearly
30,000 adult American White Pelicans took off last year, leaving
their young and eggs behind. Normally, the pelicans will stay at
the Chase Lake NWR through September.
Officials
still can't determine what caused last year's mass departure. Some
remains from this year's disaster have been sent to the USGS lab
at Madison, Wisconsin; results are pending.
Refuge
officials said large die-offs of pelican chicks have also been reported
in July at Medicine Lake National Wildlife Refuge in northeast Montana
and near Waubay National Wildlife Refuge in northeast South Dakota.
It
is thought that West Nile virus may be to blame for the chick deaths
in Montana and perhaps in South Dakota, but that may have no relation
to what has happened at Chase Lake.
In
late July, Congress included language in the passage of Interior
Appropriations raising concerns about the pelicans at Chase Lake.
This requires the USFWS to report back to the House and Senate Committees
on Appropriations by 1 October 2005, on the causes of nest abandonment
and deaths.

SEABIRD QUANDARY OFF OUR SHORES
Last
year, there was a major collapse among nesting seabirds in the North
Sea, with many colonies in Scotland, for instance, failing to breed.
This breeding failure was attributed to an insufficient supply of
food in the form of small bait fish. This year, a North Sea fishing
ban on Sand Launce (Sand Eel, Ammodytes sp.), a small and slender
bait fish, was initiated. A benefit of this ban would be to hopefully
offset a repeat of 2004's worst breeding season on record for such
species as Northern Fulmar, Atlantic Puffin, and Arctic Tern. (The
ban is also intended to promote the recovery of precious Cod and
Haddock stocks, fish species that feed heavily on Sand Eels.) The
North Sea ban this year may be too late to help the seabirds, however.
(Some North Sea Atlantic Puffin colonies, for example, have experienced
similar collapse this year.) Climate change has caused North Sea
temperatures to rise by two degrees Celsius since the 1970s. This
is thought to have reduced survival rates for newly hatched Sand
Eels by reducing the plankton upon which they feed. This in turn,
has had an impact on nesting seabirds.
A parallel
phenomenon may now be occurring off our shores. This year, in the
Pacific, from California to Alaska there have been some ominous
signs. Record numbers of dead seabirds have been washing up on beaches,
at least from Central California to British Columbia, and marine
biologists are concerned over the possibility that rising ocean
temperatures may be responsible for dwindling plankton populations.
The
coastal ocean temperatures are 2 to 5 degrees above normal, which
could be related to reduced upwelling, the seasonal movement of
cold, nutrient-rich offshore water into areas closer to the surface
and closer to shore.
This
cold water sustains huge quantities of phytoplankton and zooplankton,
the base of the marine food web. During periods of active upwelling
and resulting plankton "blooms," everything from Pacific salmon
to Blue Whales can fatten up and thrive on the continental shelf
off the West Coast. The larger fish and baleen whales eat mostly
krill, for example. Krill are free-floating, shrimp-like crustaceans
ranging from one to two inches in length that represent the upper
size limit among the zooplankton. When the water is cold, krill
swarm off the Northern California coast by the tens of thousands
of tons. Now, however, they are largely absent, and fisheries and
other marine wildlife species are feeling the effects, seabirds
among them.
On
Washington beaches, bird surveyors in May typically find an average
of one dead Brandt's Cormorant for every 34 miles of beach surveyed.
This year, the deaths averaged one every eight-tenths of a mile,
according to data gathered by volunteers with the Coastal Observation
and Seabird Survey Team. This is somewhere between five and 10 times
the highest number of bird deaths the survey has ever previously
witnessed.
Off
the coast of Oregon, abnormally warm marine water continued unabated
in July, affecting both local birds and salmon. A major die-off
of Double-crested Cormorants recently occurred in Oregon, and juvenile
salmon numbers have dropped precipitously. These events are also
thought to be due to warmer than normal water temperatures. The
water temperature off Oregon in late June would normally have been
10 degrees Celsius (about 50 Fahrenheit), and this year it was 16
degrees (about 61 Fahrenheit). The upper layer of warm water is
normally 15 meters thick, yet this year it was 30 meters thick.
Krill numbers are significantly lower than usual, and the plankton
species present this year are unusual, including many warm-water
species more normally found off San Diego or Monterey.
Concurrently,
ornithologists have reported more or less total breeding failure
of seabirds nesting on Triangle Island off the north Coast of Vancouver
Island, British Columbia, and elsewhere in the province.
Perhaps
the most dire development is that seabird nesting has dropped significantly
on the Farallon Islands off San Francisco, the largest Pacific Coast
seabird rookery south of Alaska. Bill Sydeman, the director of marine
ecology for the Point Reyes Bird Observatory, said that the crash
of the Farallon nesting season is unprecedented in the three decades
that the observatory has monitored the islands. Cassin's Auklets
have been particularly hard hit, Sydeman said. Normally Cassin's
Auklets will breed in March, but they got started late this year.
By May they had virtually disappeared. Sydeman explains that zero
nesting success - or close to it - is expected this year for the
auklets. He adds that other seabirds are also showing t he effects
of the reduced marine productivity. "We have little or no nesting
of Pelagic Cormorants (at the Farallones), and Brandt's Cormorants
are nesting at reduced numbers," he said. "Double- crested Cormorant
nesting is down by 50 percent (in the Bay Area)."
Sydeman
is not definite over the exact cause. (Upwelling cessation is typically
caused by El Niño events, warm water intrusions from the equatorial
Pacific. But apparently what is happening off the coast right now
is not a true El Niño.) Typical El Niños can be tracked as they
progress from the equator to temperate waters, something that hasn't
occurred in the current case. "Some are calling it an El Niño Norte;
others think it's some sort of anomalous intrusion of warm offshore
blue water onto the continental shelf," Sydeman said.
Of
greatest concern is the fact that the phenomenon may be long term,
and could be linked to a global warming trend. In mid-July, Fisheries
and Oceans Canada - the federal agency dealing with Canada's marine
and inland waters - released a report saying that the 2004 spring
and summer ocean surface temperatures in the Gulf of Alaska and
off British Columbia were the warmest in 50 years. The study concluded
that the record high temperatures were caused by abnormally warm
weather in Alaska and western Canada, as well as "general warming
of global lands and oceans."
Meanwhile,
near San Francisco, salmon have switched from eating krill to bait
fish, and they appear to be holding their own, with salmon filling
up on anchovies and sardines instead of krill. However, the bait
fish are generally too big for auklets to eat, and even for other
species like Common Murres, observes Roger Thomas, the president
of the Golden Gate Fishermen's Association.
Researchers
claim that krill are the keystone forage species for almost everything
that swims off that part of the coast. "It's the krill that drive
the food web dynamics off this coast," said Ellie Cohen, the Executive
Director of the Point Reyes Bird Observatory. "Their absence has
tremendous implications for everything out there, right up to the
Humpback and Blue Whales. We don't know if this is a result of global
warming or some natural cycling, but without the krill, you could
be looking at a food web collapse."
Simultaneously,
on our Atlantic shores, wildlife officials have been investigating
the mysterious deaths of hundreds of seabirds washed up on beaches
along the Atlantic coast since mid-June. Most of the birds have
been Greater Shearwaters, a species rarely seen by beachgoers because
the birds typically stay miles offshore where they feed on small
fish and squid. (In one case, at the Back Bay National Wildlife
Refuge in Virginia Beach, about 25 to 30 dead and dying Greater
Shearwaters have been found along the shore. Most were juveniles,
and most were emaciated.) In fact, more than 600 dead seabirds have
been reported from Maryland to Florida since mid-June.
Wildlife
pathologists are examining the carcasses for exposure to toxins,
pollutants such as heavy metals, and infections that might indicate
a broader environmental concern. Tests on a couple of the birds
ruled out toxins found in red tide, a type of dinoflagellate bloom
that biologists initially suspected as the culprit. A number of
Greater Shearwaters have also had their stomachs examined; the birds'
stomachs were empty, but they had varying levels of fat reserves,
suggesting that they did not die of starvation. They were below
normal weight, "but that's normal when they're in migration," observed
Will Post, ornithologist and curator at The Charleston Museum in
South Carolina.
Whatever
the problems at sea - Pacific or Atlantic - they are becoming increasingly
obvious.

BIRD-TRANSPORTED POLLUTION
And
speaking of seabirds, a recent study from Arctic Canada illustrates
the degree to which even remote, sea-foraging birds can accumulate
mercury and pesticide residue that eventually shows up near nesting
colonies.
On
Devon Island, 640 kilometers north of the Arctic Circle, Northern
Fulmars nesting on rocky cliffs bring in most of their food from
the seas between Ellesmere Island and Greenland, 400 kilometers
away. Below the high nesting-cliffs of Devon Island, the Northern
Fulmars deposit quantities of guano. With 10,000 pairs of nesting
Northern Fulmars, the accumulated guano can be considerable, with
the downpour of nitrogen- rich guano seasonally nourishing the algae
in nearby ponds and the mosses on rocks below the nest ledges Ponds
on the island closest to the colony, where more of the fulmars'
guano and debris fall, have much higher concentrations of pollutants
than do ponds situated farther from the colony. So says Jules Blais
of the University of Ottawa in Ontario. Blais and his colleagues
report that three of these ponds contain so much mercury that they
neared or surpassed Canada's limit for wildlife safety.
In
their study, the researchers tested sediments in 11 ponds on the
island at various distances from the colony. Contamination in the
sediment increased 10-fold for the pesticide hexachlorobenzene and
25-fold for mercury. Although DDT is banned in much of the world,
concentrations of that pesticide increased 60-fold across the ponds.
Apparently, there was a similar pattern for PCBs.
The
fulmars are "acting as a funnel," unintentionally collecting contaminants
by eating fish in the broad area where they forage and concentrating
them at their breeding colony, says Blais.
"This
is important from a subsistence standpoint," adds Deborah Rocque
of the USFWS in Anchorage. People living, hunting, and fishing near
bird colonies might also benefit from this disturbing finding about
bird-transported pollution.

LWCF AFTERMATH
Last month we outlined the difficulties this year confronting the Land
and Water Conservation Fund, with the House slashing the fund to
a little over $40 million and the Senate providing some small respite
with a number of $192 million for federal and stateside funding
combined. (That Senate number was still $66 million less than last
year's total LWCF, a 26 percent cut.)
We speculated that if both houses "split the difference" the number would
be $117.6 million, or a 54 percent cut from FY 05 and still $12
million less than President Bush recommended for FY06.
Well, the conference number in late July moved up to almost $143 million,
about $10 million more than the President requested, but still about
$115 million less than last year. Unfortunately, the stateside portion
plummeted: it was $92.5 million in FY05; it's only $28.4 for FY06.
One item of good news on the federal side: the $809,000 worth of possible
Ivory-billed Woodpecker habitat at the Cache River National Wildlife
Refuge in Arkansas was included in the final bill.

REFUGE PHOTO CONTEST UNDERWAY
The
National Wildlife Refuge Association (NWRA) and Swarovski Optik
of North America (SONA) launched the 2005 Refuge Photo Contest last
month. This digital photo contest is designed to showcase America's
National Wildlife Refuge System.
Submitted
images can be of birds, mammals, insects, fish, other animals, plants,
people, or simply refuge scenery, in short, almost any sight at
a National Wildlife Refuge can be offered in this contest. The contest
ends in December.
There
are Swarovski products and other prizes as awards. See the Contest
web page for more information on all the prizes, as well as
on procedures, rules, and other details.

WILDERNESS DESIGNATION PASSES SENATE
In
late July, four wilderness conservation measures were passed by
the U.S. Senate; the legislation would protect wild lands in California,
New Mexico, Washington, and Puerto Rico. The Puerto Rican inclusion
covers part of the Caribbean National Forest, which would protect
tropical rainforest habitat for the endangered Puerto Rican Parrot,
the endemic Elfin Woods Warbler, and other birds and wildlife located
in Puerto Rico's "El Yunque" forest. The Caribbean National Forest
Act (S.272 and H.R.539) would designate 10,000 acres of forest in
Puerto Rico as the "El Toro Wilderness," the first tropical forest
wilderness covered by the Wilderness Act. (We introduced this subject
in our June 2005 E-bulletin.) The legislation for the Puerto Rican
wilderness has yet to pass the House of Representatives in this
Congress. Click here for

USDA ANNOUNCES $5 MILLION FOR SAGE-GROUSE
As we reported in this E-bulletin, at the beginning of this year, the
USFWS completed a status review of the Greater Sage-Grouse and determined
that the species did not warrant protection under the Endangered
Species Act (ESA). At the same time, federal and state authorities
have recognized that a failure to protect and enhance the species'
habitat could modify the bird's status and bring about ESA reconsideration,
listing, and associated land-use restrictions.
Once fairly common in the pioneer West, the Greater Sage-Grouse has experienced
a dramatic population decline during the past several decades. It
is the loss of sagebrush habitat that is perceived as the major
culprit. Moreover, it is private lands that currently comprise almost
30 percent (about 40 million acres) of the remaining Greater Sage-Grouse
habitat.
On 13 July, the U.S. Department of Agriculture (USDA) designated $5 million
for special projects to protect and enhance habitat for the Greater
Sage-Grouse on private lands in 11 western states (California, Colorado,
Idaho, Montana, Nevada, North Dakota, Oregon, South Dakota, Utah,
Washington and Wyoming).
The USDA funds will be made available through three voluntary conservation
programs: $2.7 million from the Grassland Reserve Program (GRP);
$1 million from the Wildlife Habitat Incentives Program (WHIP);
and $1.3 million from the Environmental Quality Incentives Program
(EQIP).
This approach in funding is in line with the Bush Administration's executive
order and pledge of "Cooperative Conservation" for special projects
on private lands.

SIX STEPS FOR BACKYARD FEEDING
The
Wild Bird Feeding Industry (WBFI) and its member companies have
sponsored the development of a new website, with information on
the "six steps" designed to assist bird-feeding enthusiasts in their
efforts to attract a variety of birds to their property, as well
as a guide to providing a healthy environment.
These
steps, promoted by the industry, were produced in cooperation with
a number of organizations, including the American Bird Conservancy,
Massachusetts Audubon, The Wildlife Society, and others. For more

READY
FOR A SWIFT NIGHT OUT?
You
can join in a continent-wide effort to raise awareness about and
encourage interest in Chimney Swifts and Vaux's Swifts. It's called
"A Swift Night Out."
Post-nesting
communal roosts of swifts form as summer draws to a close. Some
of these roosts may consist of an extended family group of a half
a dozen birds, but larger sites can actually host hundreds or even
thousands of birds.
If
you locate roots at dusk right now, you'll be in a position to join
in the counts. (Look for a tall shaft, chimney, or similar structure
to locate where Chimney Swifts - central-states to east coast- or
Vaux's Swift - Pacific coast- go to roost in your area.)
On
one night over the weekend of 12, 13, 14 August, and/or 9, 10, 11
September, you can observe the roost starting about 30 minutes before
dusk and estimate the number of swifts that enter. When you have
finished your count, you can submit your results on- line.

JIM CLEMENTS (1927-2005)
Dr.
James Franklin Clements, author of BIRDS OF THE WORLD, A CHECK LIST,
passed away in June from complications associated with acute myloid
leukemia.
Jim
received his Ph.D. from California Western University in 1975 when
he was almost 50 years of age. His thesis became the first edition
of his checklist, which has since been published in five editions,
designed to classify each of the 9,800+ birds of the world.
After
retiring in 1988, Jim Clements founded Ibis Publishing Company,
and he subsequently produced a number of books.
Jim's
checklist was an ambitious effort, and for many people it became
the standard for listing the world's birds. It started humbly and
amid criticism, but with every edition the list became more authoritative,
especially since it was updated regularly in order to reflect our
understanding of the world's birds. Jim's book reached its fifth
edition in 2000, and he published regular supplements on his webpage.
Recently
he received the honor of having a species named after him, the Iquitos
Gnatcatcher (Polioptila clementsi).
His
contributions and enthusiasm will long be remembered.

STAMP REMINDER
Last
month, we mentioned the July release of the new 2005-2006 Migratory
Bird Hunting and Conservation [Duck] Stamp. It may not always be
easy to find - check your refuge offices and larger post offices,
for starters - but it's worth the investment in migratory bird and
refuge support. And most importantly, remember, it's not "just for
ducks."
