Alachua, Fla. — A large, flightless bird called the world's "most dangerous" attacked and killed its owner when the man fell on his farm in Florida, authorities said Saturday. The Alachua County Sheriff's office told CBS affiliate WGFL-TV that a cassowary killed the man Friday on the property near Gainesville, likely using its long claws.

The victim was apparently breeding the birds, which are native to Australia and New Guinea, state wildlife officials said.

"My understanding is that the gentleman was in the vicinity of the bird and at some point fell. When he fell, he was attacked," Deputy Chief Jeff Taylor told the Gainesville Sun. He said first responders got a call at 10 a.m. Friday and rushed the man to a hospital for trauma care but he died.

The county sheriff's office identified the victim as Marvin Hajos, 75, and said a death investigation has been opened.

"Initial information indicates that this was a tragic accident for Mr. Hajos," said Lt. Brett Rhodenizer, a sheriff's office spokesman, in an email to the paper. "The cassowary involved remains secured on private property at this time."

Cassowaries are similar to emus and stand up to 6 feet tall and weigh up to 130 pounds, with black body feathers and distinctive, bright blue heads and necks.

The San Diego Zoo's website calls the cassowary the "world's most dangerous bird" with a four-inch, "dagger-like" claw on each foot. The zoo says it is second heaviest bird in the world, after its cousin the ostrich.

"The cassowary can slice open any predator or potential threat with a single swift kick. Powerful legs help the cassowary run up to 31 miles per hour through the dense forest underbrush," the website says.

The bird can also jump nearly 7 feet up into the air, the zoo says.

Cassowaries are eaten in parts of New Guinea. The birds are not raised for food in the U.S., but are sought after by collectors of exotic birds, according to authorities.

To obtain a mandatory permit, the Florida Fish and Wildlife Conservation Commission requires cassowary owners to have "substantial experience" and meet specific cage requirements, spokeswoman Karen Parker told the newspaper. She said the commission lists the cassowary as a type of wildlife that can "pose a danger to people."

Wildlife officials did not answer phone calls late Saturday from The Associated Press and it wasn't immediately known what would happen with the bird.
