An Illinois man drowned in a pond after falling off his kayak when a swan attacked him, with his death ruled an accident Sunday.

Anthony Hensley, 37, was working Saturday -- as part of his job keeping geese away from a condominium complex near Des Plaines -- when it is thought he got too close to a swan and it attacked him, the Chicago Sun-Times reported.

The swan had been placed in the pond by the company Hensley was working for, in a bid to keep geese away.

Hensley was checking on the swan while in his kayak, but he capsized after the bird moved towards him.

Witnesses saw him come up to the surface a couple of times before he went under again and did not resurface.

He was taken in serious condition to Lutheran General Hospital where he died.

On Sunday, following an autopsy, Hensley's death was ruled to be from accidental drowning, the Sun-Times reported.
