NASHVILLE, Tenn. – It's being called the "turkey of a lifetime" by the Tennessee Wildlife Resources Agency.

That's how officials described a rare leucistic gobbler killed by a hunter in Rutherford County last week.

Cameron Bond of Warren County shot the unusual bird on April 6.

Leucism in birds, according to the wildlife resources agency, is a loss of pigmentation. It is a genetic abnormality.

The beard on the turkey Bond killed was dark, and the back feathers still held some color.

Bond said the turkey weighed 20 pounds. It's beard measured 9½ inches and its spurs were three-quarters of an inch.

Spring turkey hunting season in Tennessee opened March 31 and continues through May 1.
