"Deadly bird flu not forgotten by U.S health officials"
Quote:Now, with the disease still centered in Asia and the failure of
migratory birds to spread the illness to Europe and North America,
the H5N1 virus has dropped out of the media spotlight. The dearth of
coverage has prompted some to think that the threat of a pandemic has
passed.
Health officials were surprised when flocks of migratory birds that
had flown south to Africa and then back to Europe last spring didn't
carry the H5N1 virus as expected. Neither did birds that wintered in
Asia and flew to Alaska last summer to breed. International bird
monitors also found no widespread deaths from the virus among
migratory birds.
Many experts now think that wild migratory birds are only bit players
in the spread of the disease. More likely culprits are humans who
clean, feed and house infected domestic birds and those who prepare
infected birds and transport them to commercial markets, said Rick
Kearney, wildlife program coordinator with the U.S. Geological
Survey.
"Migratory birds may contract the disease and continue in their
migration, but they clearly don't play a major or single role in
spreading the disease," Kearney said. |

Sadly, the health officials should not have been surprised. But, way too much stupidity re bird flu; poultry industry - helped by FAO (readily blaming wild birds prior to above statement, and never mind the facts) - has managed some effective obfuscation of truth.
Here in Hong Kong, can hope that situation will remain calm, and that won't again have daft measures like Mai Po closure without H5N1 present there. (With Wetland Park, may be tougher to shut Mai Po now - the park being supposedly a big attraction, hard to close this; if shut Mai Po, could hardly justify the W Park staying open.) |

ID thanks to 䰇ohnallcock
The posting on the 1st Sept (photo taken 25 Aug)appears to show a juvenile Lesser Coucal rather than Greater.
Note the pale face, chestnut on the crown, streaked (rather than barred) appearance to the upperparts, dark back, relatively short bill and dark (grey) eye.
Juvenile Greater Coucal is generally rather similar to adults but with white barring the the black feathers (and of course dark barring on the wings)
Note that adult Lesser Coucals moult into a brown, streaked plumage (similar to the juveniles) during the winter but would not show barring on the wings.
