(CNN) – some of the best experts of the nation Tuesday were seeking clues about the sudden death, the mass of the bird in two States new year's weekend.

"It is unusual because of the period on which all birds dead," says LeAnn White, national wildlife health center field investigator in Madison (Wisconsin). Centre, part of the U.S. Geological Survey, receives samples of Arkansas, where up to 5,000 Blackbirds and starlings fell from the sky miles square in less than an hour on the eve of new year's Eve, according to the Commission of game and fish Arkansas area.

The centre will focus on samples of Louisiana, where the Red-Winged Blackbird 500 starlings and bronzés were found dead in LaBarre.

A preliminary report carried out by the Commission of poultry and livestock Arkansas Monday found that birds in Beebe, Arkansas, probably as a result of massive trauma.

There were reports of intense in Beebe sounds until birds falling reports are starting to come. It is possible the sounds that birds disoriented, and they went into sudden and chaotic, flight crashed in the other and objects, said White. "You're disturbed, you're confused, you try to know where you are." "We have seen things like this before when it is dense fog and they run in towers and electric lines," she says.

Other bird experts agree it's a plausible explanation. But the sudden death are quite unusual. "It's a freak, event type," said Greg Butcher, Director of the conservation of birds of the National Audubon Society. "You just see this kind of massive death very often at all."

In this time of year, Blackbirds are in huge deposits, particularly in South-East of the United States, he said. They are generally not fly at night.

"In the course of a year, half the birds are around die - even under the best circumstances." The bird life is short and sharp. "But it happens just generally out of sight of people," said Boucher.

It is possible that the loud noise that triggered the incident was fireworks on the eve of the day of the year, although officials said the investigation is underway.

"If it was all the other days of the week," said Butcher, it could suspected of people behind death. "" "" There are many voluntary murders. ... People really don't like these large deposits. But I see someone who is on the eve of the day of the year.

Doug Inkley, senior researcher with the National Wildlife Federation said his "first suspicion is that they were frightened and went into a mass panic."

"I would call this unusual event," he said, "but without previous step.

Keith Stephens, a spokesman for the Arkansas Game and fish Commission said bird shown signs of trauma in breast tissue, with the formation of blood clots in the cavity and a lot of internal bleeding. All major organs were normal.

Karen Rowe, an ornithologist from the commission, said that these incidents can be caused by a lightning and hail high-altitude. A strong storm system crossed State earlier in the day Friday.

CNN experts speak with saw nothing surprising in that there is a similar report from the bird died in Louisiana. "This is one of these coincidences," says White, adding, I'm really interested see if there is anything that can potentially be linked. I asked it y weather conditions. It is sometimes hail high-altitude. But, she says, until now officials were unaware of "any strange weather" in the region.

Butcher with the National Audubon Society, said that there may be reports more dead birds found throughout the country. "As soon as one of these things hitting the waves, people are just more sensitive to see around dead birds."

In the meantime, Arkansas officials are investigating the estimated 100,000 fish death in the Northwest of the State, but suspect disease was to blame, a State spokesman said Sunday.
