Yes, this is especially true for mute swans which are large and easily noticed, but they don't migrate over long distances.

The key point however is the fact that H5N1 can easily move from species to species and need not use one bird or one species to move from point A to point B. Nature reserves are major mixing bowls, both of viral genes as well as species carriers. At Qinghai Lake in 2005, initially all infected birds were bar-headed geese, but by the time China filed their OIE report, 5 migrating species were named (and more species were subsequently reported).

Same thing happened in Germany, Initially, the largest outbreak was almost exclusively black necked grebes, but within a few weeks there were multiple species that were H5N1 positive. At Uvs Lake in 2006 H5N1 was isolated from ducks, grebes, whooper swans, and golden eyes,

H5N1 knows how to get around.

Caution is urged to avoid bird flu
By Jennifer H. Svan, Stars and Stripes
Pacific edition, Friday, May 2, 2008

MISAWA AIR BASE, Japan ? Following the discovery of the deadly bird flu virus in at least three swans at popular tourist site Lake Towada, Misawa Air Base?s public health flight commander is urging Americans to use caution around wild birds but says the risk to the base population is ?low to none.?

Maj. Mahendra Kabbur said people should avoid traveling to wild bird sanctuaries, such as Kabushima, also known as ?Seagull Island,? and refrain from feeding wild birds at local waters. Besides Towada, those include Magi pond at Shimoda Park and Lake Ogawara at the base beach.

?Although chances of catching bird flu [are] low to none, following precautionary measures should help to minimize any risk associated with contracting bird flu,? Kabbur wrote in an e-mail to Stars and Stripes.

One dying and three dead swans were discovered April 21 near Lake Towada. The Japanese government confirmed Tuesday the dead swans were infected with the virulent H5N1 strain of avian influenza, which has killed tens of millions of birds since the first cases were reported in Hong Kong in 1997.

Lake Towada, the largest caldera lake on Japan?s main island of Honshu, is about 35 miles southwest of the air base. It?s one of several winter destinations in the area for migratory swans from Siberia.

At Lake Towada and Shimoda, people can purchase bread crumbs or feed to toss to the swans. Shimoda?s swan festival in March is popular with Americans.

People should avoid contact with sick or dead birds, Kabbur said. He noted that the majority of bird flu cases in humans around the world involve people working directly with birds, such as at chicken farms.

?Also, still today, human to human spread is not well established,? he wrote Wednesday.

At least 240 people have died from the bird flu since 2003, according to the World Health Organization.

Most human cases so far have been linked to contact with H5N1-infected poultry or H5N1-contaminated surfaces, according to the U.S. Centers for Disease Control and Prevention.

Infected birds shed influenza virus in their saliva, nasal secretions and feces, according to CDC.

The dead swans are Japan?s first outbreak of H5N1 since March 2007, when researchers found the virus in an eagle on the southern island of Kyushu.

Whooper Swans have been known to inhabit the outer Aleutian Islands of Attu, Atka, Amchitka, Kanaga, & St. Paul in the late fall, winter, and early spring.

In late May and June, these islands act as magnets for Asian species that make their first North American appearance on the islands.

Dead swan in Hokkaido tests positive for bird flu


A dead swan found in the Notsuke Peninsula in eastern Hokkaido has tested positive for bird flu virus, the Environment Ministry said Thursday.


On the lookout: Local health officials testing for avian influenza look for bird droppings at Lake Towada in Akita Prefecture on Thursday. KYODO PHOTO

Hokkaido University will test it further to determine if the virus is highly pathogenic. The swan was found April 24.

Earlier Thursday, the ministry began testing wild swans, geese and ducks for bird flu in Hokkaido, Akita and Aomori prefectures. The action follows the discovery of the deadly H5N1 strain of avian influenza in three of four swans found dead or dying near Lake Towada in Akita Prefecture on April 21.

The ministry plans to collect droppings from 20 to 100 birds at test spots around lakes and rivers for several days to see if they contain avian influenza.

Bird Flu Confirmed in Swan in Hokkaido Japan

Recombinomics Commentary 23:50
May 1, 2008

A dead swan found in the Notsuke Peninsula in eastern Hokkaido has tested positive for bird flu virus, the Environment Ministry said Thursday.

The swan was found April 24

The ministry plans to collect droppings from 20 to 100 birds at test spots around lakes and rivers for several days to see if they contain avian influenza.

The above comments described another dead swan testing positive for bird flu. Since low path avian influenza rarely kills waterfowl, the bird flu will almost certainly be H5N1. The location of the latest reported positive is almost 300 miles northeast of the confirmed H5N1 infected swans in Akita, indicating the infections are widespread (see satellite map). The outbreaks in South Korea are approximately 500 miles southwest of Akita. Earlier reports indicated additional dead swans in Japan were being tested.

These data support spread of H5N1 by migratory birds over a wide area in Japan and South Korea. The outbreak in South Korea has led to the culling of more than 6 million birds and the closure of wet markets. The detection of bird flu in dead swans at two very distinct locations in Japan suggests that more positive birds will be found if surveillance in enhanced, although testing of 20 ? 100 bird droppings is unlikely to produce many positives because the H5N1 is almost certainly clade 2.2, and viral levels in fecal samples is low.

These latest finding in Japan and South Korea, as well as Primorie in southeastern Russia, suggest H5N1 is widespread in these three countries, and will affect additional areas as these migratory birds fly north to multiple locations including areas in North America.

Dead swan found in Hokkaido tests positive for influenza virus

Friday 02nd May, 03:17 AM JST
TOKYO ?
A dead swan found in the Notsuke Peninsula in eastern Hokkaido tested positive for avian influenza virus in a simple examination, the Environment Ministry said Thursday. Hokkaido University will conduct a probe to determine if the virus is high-pathogenic, according to the ministry.
The swan was found on April 24. The deadly H5N1 strain of avian influenza virus was detected in three out of four swans found dead or dying near Lake Towada in Akita Prefecture on April 21.

Re: Japan detects bird flu in wild swans

The video shows lots of Northern Pintails swimming along with the Whooper Swans...

Assessment of virus movement across continents: using Northern Pintails (Anas acuta) as a test

A collaborative study between U.S. and Japanese researchers


Band recoveries indicate that most Northern Pintails which winter in Japan originate from nesting areas on the Chukotka and Kamchatka peninsulas in eastern Russia (Yamashina Institute for Ornithology 1985, Bianki and Dobrynina 1997). Twenty-two Northern Pintails that have been marked on breeding or molting areas in North America have also been recovered during winter in Japan (Yamashina Institute for Ornithology 2004, Nicolai et al. 2005). Conversely, there are at least 37 winter recoveries in North America of Northern Pintails that were banded at wintering sites in Japan (Yamashina Institute for Ornithology 2004). Furthermore, some Northern Pintails migrate from wintering areas in North America to nesting and molting areas in eastern Russia (Rienecker 1987, Miller et al. 2005), where they could come into contact with birds that migrate from Asian wintering sites. Thus transcontinental exchange of avian-borne pathogens could occur through (1) mixing of North American and Asian migrants on shared summer habitats in eastern Russia, (2) Northern Pintails that migrate between North American nesting areas and Asian wintering areas, or (3) birds that shift wintering sites from Asia to North America.


Northern Pintails sampled in North America and Japan have been found to carry a wide variety of influenza viruses (Ito et al. 1995, Shengoing et al. 2002). During a three-year study in Canada, influenza viruses were isolated from 256 of 745 (34%) Northern Pintails sampled (Hinshaw et al. 1980). Ito et al. (1995) found 8 different subtypes of avian influenza viruses

Akita chicken farms inspected for deadly flu
AKITA (Kyodo) Akita Prefecture on Wednesday began two days of on-site inspections of chicken farms near Lake Towada after the deadly H5N1 strain of avian influenza was detected in dead swans found in a lakeside town.
Municipal officials, together with officials from a livestock hygiene service center, will instruct the farmers about thorough sterilization as well as the use of bird nets and other measures to prevent wild birds from entering their farms.

<!-- MooterMedia Javascript Ad Snippet end here -->The deadly virus was detected in three of four swans found dead or dying April 21 near the lake in the town of Kosaka, a study by the National Institute of Animal Health showed Tuesday.
The inspections cover about 42,000 birds at 15 farms within a radius of 30 km of where the swans were found.
Akita Prefecture inspected chicken farms in Kosaka and Kazuno, a nearby city, on Wednesday. Thursday's inspections will cover farms in Odate.
The prefectural government set up a crisis management liaison office Wednesday and held a meeting to discuss measures to cope with the detection of the deadly virus.
Chickens infected with the H5N1 virus have so far not been confirmed in the prefecture. The inspections are based on a request by the Agriculture, Forestry and Fisheries Ministry.
Neighboring Aomori and Iwate prefectures are conducting similar inspections.
According to Aomori Prefecture, an emaciated swan was captured at a hotel in the city of Towada on April 18.
The swan died two days later and the cause of death is unknown, the prefecture said.
At a news conference in Tokyo, Environment Minister Ichiro Kamoshita said his ministry has dispatched officials to Hokkaido and Akita and Aomori prefectures to collect bird droppings and test them for the H5NI virus.
"Since there seems to have been no influence (of the virus) on domestic poultry, we'd like to grasp the influence on wild birds accurately," Kamoshita said. The virus "happened to be found in Lake Towada, but it could happen elsewhere in Japan."
The outbreak of the H5N1 virus is the first in Japan since March 2007, when the virus was found in an eagle in Sagara, Kumamoto Prefecture.
The deadly H5N1 strain has been spreading in fowl in southwestern districts of South Korea since April and concern was growing that migratory birds might bring the virus to Japan.

Re: Japan detects bird flu in wild swans

In Hokkaido the bird in full article is printed from the swan of the death The cadaver of the swan which is found in the Towada lakeside of Akita prefecture Kosaka Cho (it did and to be) from with the problem where the bird influenza virus of H5N1 type is detected, as for the environmental ministry announced that on the 1st, it was discovered on April 24th with the Hokkaido eastern field attaching peninsula from the swan which dies, you could obtain the positive reaction of the bird influenza virus in simplicity inspection. It is strong, whether or not H5N1 type of poison type and so on, being Hokkaido large, it carries out detailed inspection. In addition it is found when in Aomori prefecture six place villages you weaken on April 23rd, is young the bird of the swan which dies 4 days later Kitasato large (the same prefectural Towada city) due to the result of the virus inspection, being negative was ascertained. The environmental ministry from 1 day, being joint with Hokkaido, Aomori and Akita both prefectures, around Towadako and at wild bird coming flying area such as Hokkaido Wakkanai city, starting the investigation in order to grasp the infection circumstance of the other wild bird. It extracts the droppings of the bird from the lake, and the shore of the rivers and the like the national environmental laboratory (Ibaraki prefecture Tsukuba city) sends and inspects the presence of the virus. Several days it continues investigation in the future in such as Hokkaido. Around Towadako on the 1st, the economical staffs 1 lap did the lakeside, but the wild bird which has the possibility of dying being lesion, weakening says that it was not found. Using the spoon, approximately 30 it extracted also the droppings. Even in Hokkaido approximately 300 it picked in Onuma of Wakkanai city and the クッチャロ lake of Hamatonbetsu Cho. Akita prefecture enters on the 1st, the poultry farming farmer 8 door which is within radius 30 kilometers from the place where the cadaver of the swan is found in Kosaka Cho, investigation. Aomori prefecture the farmer of 78 door inside the prefectures was investigated to the same day, but in each case there was no abnormality. [ 2008 May 1st 22:14

Re: Japan detects bird flu in wild swans

On the 1st, the cadaver of オオハクチョウ which is collected in Hokkaido Bekkai Cho (to do the environmental economical Kushiro natural environment office and be) when you inspect simply, it announced that the bird influenza virus (A type) the positive reaction was produced. Because also the possibility of the same strongly poisonous H5N1 type as the swan which is found in the Towada lakeside of Akita prefecture it is, in the future, you inspect in detail at the Hokkaido large scholar animal common infection symptom research center. According to the same ministry, when the Kushiro natural environment office, the veterinarian of Nakashibetsu Cho has kept the cadaver of オオハクチョウ which in Bekkai Cho is found on April 24th, information offer was received. Because of this the cadaver was collected on the 1st, when the mucous membrane and the droppings etc. are inspected simply, the positive reaction of the bird influenza virus was produced. To understand whether or not the virus is strong poisonous H5N1 type, 2, you say that 3 weeks it is required. < Related news >

Re: Japan detects bird flu in wild swans

Abnormality there are no 30 kilometer inside Ministry of Agriculture Forestry and Fisheries, in bird in full investigation:39 of 2008 May 2nd 21 With the problem where in Akita prefecture the bird influenza virus of H5N1 type is detected from the cadaver of the swan, as for Ministry of Agriculture Forestry and Fisheries on the 2nd, at the poultry farming place of the total 56 place of Akita, Aomori and Iwate 3 prefecture which are from the heuristic place to radius 30 kilometer inside as for abnormality it was not discovered, that it announced. Even in Hokkaido, from the cadaver of the swan the positive reaction of the virus was produced in simplicity inspection, but there was no abnormality in the poultry farming place of 5 places which is on 30 kilometer inside. You inspected, informed about the result Ministry of Agriculture Forestry and Fisheries whether or not 3 prefectures and Hokkaido enter in the poultry farming place which from the place where the cadaver is found is on 30 kilometer inside and execute investigation, there is no mass death and a case of weakening. You heard even in the poultry farming place outside 30 kilometer spheres and took and executed investigation and hygienic management guidance, but "abnormality is not reported", (Ministry of Agriculture Forestry and Fisheries) with you say.
