Over 8000 Bird Flu Deaths in Gangcha County Qinghai China?

Recombinomics: Over 8000 Bird Flu Deaths in Gangcha County Qinghai China?

Dr. Niman is relying on a machine translation from a Chinese language website where anyone can post. As Crawford Kilian notes, this sounds like Nostradamus.

I think some perspective is necessary. Wild animals die all the time for a variety of reasons. Waterfowl are susceptible to several diseases that cause mass mortalities: thousands of birds die every year in North America from diseases such as avian cholera, duck plague, and avian botulism (a field manual of wild bird diseases is available here). Just skim through this report posted by the United States Geological Survey National Wildlife Health Center where die-offs of many thousands of waterfowl occur regularly.

Apparently more than 100,000 birds congregate on this lake every year. 8000 deaths is likely not only precedented, but possibly normal.

I repeat my earlier cautions. Assuming that these numbers are accurate, we don't know what killed these animals. Just because H5N1 was isolated there doesn't mean it killed every animal that dies.

Update: Dr. Niman is linking to photos apparently showing thousands of dead birds. To me, the nice, uniform spacing between birds, the resting and standing poses suggest that these are nesting birds (although there likely are dead birds in there - birds die all the time). This is what a waterfowl mortality event looks like to me.

The chinese government has acknowleged that the bird sickness in that area is being caused by H5N1, and was likely brought there by migrating bar-headed geese. The gov't is rushing H5N1 vaccine to the area as well. That indicates to me that this is very likely H5N1. Also, in such a large group of birds, there should be some activity. There are no nests. there are few birds standing or walking, there are none flying. There are simply tons, and tons of birds lying on the ground. granted, there are no close-up photos, but the one you posted for comparison is of birds that washed up on the tide, that are already quite rotten. The timescale for this outbreak has not progressed to that point yet. These pictures look like what they are passed off as, sick birds.
