Austin Community News >> Theories Behind Dead Birds in Downtown Austin

1/13/2007 AUSTIN – Whatever caused dozens of birds to drop dead in downtown Austin probably was not a public health threat, officials said Tuesday.

But Austinites are posing their own theories to the city's health department – like maybe the birds were flying drunk.

Authorities discovered 63 dead birds overnight Monday on Congress Avenue leading to the state Capitol. Officials are awaiting lab results to determine the cause that could take a week or longer.

The carcasses of the grackles, sparrows and pigeons were found between Sixth and Eighth streets. There were no reports of humans harmed, though crews in hazardous material suits shut down 10 blocks near the Capitol on the eve of the 80th legislative session while they tested for environmental contaminants and leaks.

Avian flu is not suspected, said Carole Barasch, spokeswoman for Austin-Travis County Health and Human Services. Officials have said other health threats are also unlikely, though the public is sharing plenty of conclusions.

Among the theories Barasch's office has received: the birds drank fermented berries and were intoxicated, or the birds were disoriented from new high-rise structures downtown and crashed into the reflective glass. Accidental mistletoe berry poisoning has also been suggested.

Ornithology experts believe the birds were poisoned deliberately, though Barasch said her department won't speculate until lab results are returned.

No other large bird kills have been reported since the downtown closure, Barasch said.
