Hunter bags ‘turkey of a lifetime,’ all-white feathered, 20-pound bird

Cameron Bond, of Warren County, shot the 20-pound leucistic turkey, according to the Tennessee Wildlife Resource Agency.

Leucism is a loss of pigmentation, according to wildlife officials. It is different than albinism, which is caused by a lack of melanin.

"Leucism is fairly common in birds, whereas albinism is much less common," according to Tennessee wildlife officials. "Abnormal plumages is one of the most perplexing issues that bird watchers encounter. Many people see white birds that are not normally white and call them albinos. In only a few cases is this technically true."
