More than 1,000 mallard ducks die along Idaho creek, cause unknownWednesday December 13, 2006
By JESSE HARLAN ALDERMAN
Associated Press Writer
BOISE, Idaho (AP) More than 1,000 mallard ducks have died along a single creek in southern Idaho, and officials on Wednesday tested tissue samples to find out why. The symptoms lesions in the lungs and hemorrhaging in the heart wall likely point to a bacterial infection, not avian flu, said Dave Parrish, regional supervisor for the Idaho Department of Fish and Game. State wildlife biologists and U.S. Department of Homeland Security investigators were not ruling out any cause of death. Migrating mallards from Canada and their local cousins were still perishing at Land Springs Creek near Oakley, about 180 miles southeast of Boise. Birds stagger and struggle to breathe before collapsing, said Parrish. ``There were dead mallards everywhere in the water and on the banks. It was odd, they were in a very small area,'' Parrish said. The outbreak puzzles scientists because only mallard ducks are dying. Golden eagles, geese, magpies, crows and other birds in the area all remain healthy, Parrish said. Tissue samples from the ducks and water samples from the creek were sent to the U.S. Fish and Wildlife Service national laboratory in Wisconsin, the University of Idaho and Washington State University. Results were expected Thursday. The remote waterway is surrounded by farm land. A cattle feedlot is close by and several corn and alfalfa feeds ring the nearby town of Oakley. Parrish said the ducks may have eaten grain treated with pesticides, or farming chemicals might have spilled into the creek. (Copyright 2006 by The Associated Press. All Rights Reserved.)

Nothing to see here. Just move along.
Chemicals in the creek would mean dead fish and other wild life. Does one of us need to fly out there to explain minor details?

Oh wait a minute, Didn’t I read on “my space” About a girl who knew a guy A sick guy who just returned from Thailand Carrying his pet mallard But the ICU hospital wouldn’t let him keep his duck And he ran from California to Idaho in a marathon With a Morphine IV drip? There just might be something here! |

I have wondered how long does it takes? Duck 1 (sick duck) meets duck 2 (not sick duck) now duck 2 is sick. So how long does it take for duck 2 to get sick and die? Could a bird get sick over in Asia and fly over here to the |

Rockhound,
I believe a bird could fly over in a relatively short period of time. They can fly a long way each day. If they get the virus but take 4 to 5 days to show symptoms I don't see why they couldn't make it over to North America.

Good grief… this is from the article. “The symptoms lesions in the lungs and hemorrhaging in the heart wall likely point to a bacterial infection, not avian flu, said Dave Parrish, regional supervisor for the Idaho Department of Fish and Game”. On the contrary, lesions are a primary symptom identifying HPAI H5N1. There is a lot of information about this, but here is the first thing that I found. LESIONS
With LPAI outbreaks in poultry there is mild to moderate inflammation of the trachea, sinuses, air sacs and conjunctiva. In laying birds there often is ovarian atresia and involution of the oviduct. Various degrees of congestive, hemorrhagic, transudative, and necrotic lesions have been described. In HPAI infection, gross lesions in poultry species are the most extensive and severe. Fibrinous exudates may be found on the air sacs, oviduct, pericardial sac, or on the peritoneum. Small foci of necrosis may be apparent in the skin, comb, and wattles or in the liver, kidney, spleen, or lungs. Indications of vascular damage often include congestion, edema, and hemorrhages at many sites. |

I wonder about the grain nearby, they said it had pesiticides on it, but I also wonder about a deliberate killing or posioning. ITs out there, people know ducks carry this, and it could be that this spot was one that lots of ducks were always at, and someone afraid of the flu put out posion in land and water, that they injested. It sure sounds suspect to me, if that is not it, I dont see how it could be anything but bf for that large a kill off.

The description of how Birds stagger and struggle to breathe before collapsing seems consistent with previous symptoms of AVI infected birds.

I didn't mean to alarm anyone by placing this on a sticky topic. We will remove it shortly, but we need to be sure to follow this one through until we receive the results.

Albert, good pickup on the possibility of these symptoms in birds, but my initial skimming of ducks in North America makes it not highly likely.
There is an article
Susceptibility of N. American Ducks, Gulls to H5N1 Avian Influenza Viruses at http://www.cdc.gov/NCIDOD/eid/vol12no11/pdfs/06-0652.pdf that suggests that ducks such as mallards do not show gross (visibile) lesions that might be seen in some poultry. Mallards are not among the most susceptible to H5N1. Lesions pertain to any abnormal marking on the surface or an organ, whether raised or depressed, a rash, a break, etc. This article dealt with some microscopic lesions. Most diseases in time will make some kind of lesion, so they are not characteristic of a disease until you specify what kind of lesion, where, on what organ, gross or invisible etc. |

Death count seems to be growing!Thousands of ducks mysteriously dying in IdahoWed Dec 13, 2006 10:36 PM GMT
< id=CurrentSize = value=13 name=CurrentSize>
By Laura Zuckerman SALMON, Idaho (Reuters) - Officials scrambled on Wednesday to determine what has caused the deaths of thousands of mallard ducks in south-central Idaho near the Utah border. Although wildlife experts are downplaying any links to bird flu, they have sent samples to government labs to test for the deadly H5N1 flu strain, among other pathogens. Officials with the federal Bureau of Homeland Security have been also called in to help with the probe. "We think the possibility of avian flu is very remote but we're not ruling anything out at this point in time," said Dave Parish, regional supervisor for the Idaho Department of Fish and Game. "We want to make sure all the bases are covered."
Wildlife officials are calling the massive die-off alarming, with the number of dead mallards rising from 1,000 on Tuesday to more than 2,000 by Wednesday afternoon. "We've never seen anything like this -- ever," Parrish said. A hunter alerted state conservation officials after finding a handful of dead ducks along Land Creek Springs, about 150 miles southeast of Boise, on Friday. Officials have posted signs warning hunters and others not to touch or eat the birds until a cause of death has been identified. Preliminary findings by state veterinarians suggest the mallards succumbed to a bacterial infection, officials said. They said it was unclear why a similar outbreak had never before occurred in Idaho. On Wednesday, officials outfitted with protective gear were gathering hundreds of mallard carcasses. Wildlife managers said the birds will be incinerated. The only mallard die-off roughly equivalent in recent years happened in Waterloo, Iowa in 2005, when 500 ducks died from a fungus, according to a report by the U.S. Geological Survey's National Wildlife Health Center. © Reuters 2006.

One thousand ducks is a lot of ducks to die all at one time. I hope that someone follows this so that we can get a real answer as to why these ducks die. Johnray1

Yes, other HPAI has hit in the US in Turkeys.
.........................................................................................
"...An outbreak of avian influenza in broilers in Pennsylvania and Virginia, USA, in 1983-1984 led to the slaughter of approximately 11 million birds at a cost of approximately $61 million...."
"...In Pennsylvania, mallards tested by Pennsylvania Game Commission personnel under a cooperative agreement with the USDA were found to be positive for the LPAI H5N1. In both cases, no signs of disease or death were noticed in the birds...."
"...The disease outbreaks in turkeys in the United States have been caused by AI viruses with many of the HA designations. It was in the fall of 1983 that a highly virulent H5 virus produced severe clinical disease and high mortality in chickens, turkeys, and guinea fowl in Pennsylvania. This severe disease, clinically indistinguishable from classical fowl plague, occurred after a serologically identical but apparently mild virus had been circulating in poultry in the area for 6 months...."

Albert, Thanks. I noticed that the symptoms they are describing in the field match the definition of HPAI symptoms in birds. Patiently waiting to hear what they have to say.

If HPAI come to this country via birds, it could rachet up the media coverage and more people might pay attention to the risk. Better something like this than to be blindsided by a human pandemic. Something interesting from the Nov. 2 (06) report from CIDRAP:Mallard ducks are now seen as the leading vectors in the geographic spread of H5N1; mute swans are highly susceptible to the disease but probably don't spread it.
I'm not trying to add hype here, just saying this is one more reason they'd better give us detailed test results ASAP.

You will never get true information anyway from the government. Look for othr die offs within kilometers of the area for confirmation. If they all died in one area they can easily make any excuse they want but if they begin to die off 100 or so kilometers away from the effected sight you know it is some virus. Prediction from the feds is poisoning from some pesticide.

Actually this is what the article said: "Parrish said the ducks may have eaten grain treated with pesticides, or farming chemicals might have spilled into the creek." That doesn't mean there was grain with pesticides nearby, just stating what may have happened, it could also read " monkeys may have flown out of their butts", that doesn't mean there were monkeys seen. Point is it is a speculative statement to take the focus in the media away from H5N1. It is deception. What Albert said is accurate, |

[This site has always made me feel safe and the reason I say that is that we always seem to see it on our site before it is in the news. If you are going to find out anything regarding bird flu, it will be on this site before it is seen on national news.

This is exactly the type of presentation of AVI in the states we have been expecting, and if it turns out to be H5N1, there will be many more people besides us looking here for the latest information and guideance. It could get very busy very quickly!

If this is H5N1 then this may indicate a major change in the virus. mallard ducks are usually carriers not displaying symptoms. he is a quote from the NEJM.
"Ducks may be the stealth carriers (the Trojan horses of H5N1 influenza), for wild mallard ducks do not always show signs of disease when infected with any of a range of highly pathogenic H5N1 viruses.2 Our knowledge about the efficacy of H5N1 influenza vaccines in domestic waterfowl is limited, and highly pathogenic H5N1 viruses continue to be isolated from waterfowl in the epicenter of the epidemic." http://content.nejm.org/cgi/content/full/355/21/2174 |

here is a very good article from CDC about testing on North American birds with H5N1. It talks about Mallards not developing symptoms and the birds that did die having lesions on internal organs and hemorrhaging in the heart, the same symptoms being described in this mallard die off. Interestingly this is a new report from Nov 2006.

Anybody can suspect anything they want. No proof or reason is needed to "suspect". This is one of the many words used in deceptive press releases to imply things that are not true. I suspect I might have a cup of coffee later. It means absolutely nothing, but most people will assume there is a reason to suspect something. Legally, there does not need to be a reason. The word gives false implication that there is a reason not mentioned for the suspicion. that is why it is used. I swear I am not making this stuff up. There is an entire course of study on how to do this stuff. |

I was thinking the same thing but that would make the United States no better than China and I really don't think the U.S. wants to go down in history as denying the first confirmed case of H5N1 in our Country.
2,000 Mallard ducks just can't be swept under the rug. We should hear something soon.
Susceptibility of N. American Ducks, Gulls to H5N1 Avian Influenza Viruses at http://www.cdc.gov/NCIDOD/eid/vol12no11/pdfs/06-0652.pdf that suggests that ducks such as mallards do not show gross (visible) lesions that might be seen in some poultry. Mallards are not among the most susceptible to H5N1. Dloguse: I have also record this information however please keep in mind that this virus is always adapting.
I just curious why would there be pestisides in feed? If it's in water wouldn't there be fish dieing as well?
We should be hearing smaller cases from birds that didn't stay with the flock.
