10 blocks in Austin closed after birds found dead

AUSTIN, Texas — Police shut down 10 blocks of businesses in
the heart of downtown early Monday after dozens of birds were found
dead in the streets, but officials said preliminary tests showed no
dangerous chemicals in the air.

As many as 60 dead pigeons, sparrows and grackles were found
overnight along Congress Avenue, a main route through downtown. No
human injuries or illnesses were reported.

``We do not feel there is a threat to the public health,'' said
Adolfo Valadez, the medical director for Austin and Travis County
Health and Human Services.

He said preliminary air-quality tests
showed no dangerous chemicals and the area should reopen around
noon.

U.S. Department of Homeland Security spokesman Russ Knocke said
officials had no credible information to suggest any imminent
threat to the city.

On Congress Avenue, just outside the state Capitol, emergency
workers donned yellow hazardous-material suits Monday morning, and
dozens of fire trucks and ambulances were parked nearby.

Workers were testing for any sort of environmental contaminant
or gas or chlorine leaks that might have cause the bird deaths,
said police spokeswoman Toni Chovanetz.

At least one bird carcass
was being tested locally for other possible causes, and other
carcasses were shipped to the Centers for Disease Control and
Prevention and Texas A&M University.

Valadez said the tests on the dead birds would likely take
several days and look for signs of poisoning or viral infections,
though he said officials do not think bird flu is involved.

A 10-block stretch of Congress Avenue, several side streets and
all buildings in the area were shut down and declared off-limits as
a precaution, Chovanetz said.

The street closure stretched from just outside the Capitol to a
section of the Colorado River known as Town Lake.

The Capitol
opened on schedule Monday, the day before the legislative session
was to begin.

On the East Coast, New York City also had a scare Monday morning
when a mysterious gas odor moved across Manhattan.

It wasn't
immediately clear what had caused the odor, and it dissipated
fairly quickly. No injuries or damage to wildlife was immediately
reported.
