The wild turkey is the largest game bird in North America and a major conservation comeback. Continental population dropped to an estimated 30,000 birds by the 1930s, recovered to roughly 6-7 million today, and that recovery — trap-and-transfer programs run by state agencies in partnership with the National Wild Turkey Federation — is why the species is now huntable in 49 of 50 states.
Five subspecies are recognized in the U.S. and each has its own geography. The Eastern (M. g. silvestris) covers the largest range — essentially everything east of the Great Plains plus introduced Pacific Northwest populations. The Osceola or Florida (M. g. osceola) is endemic to peninsular Florida and exists nowhere else; it is the smallest and darkest. The Rio Grande (M. g. intermedia) holds the southern Plains from Texas north into Kansas and west into New Mexico, with introductions in California, Oregon, Washington, and Hawaii. Merriam's (M. g. merriami) is the mountain subspecies of the West, in Colorado, Wyoming, Montana, the Dakotas, and the interior Northwest. Gould's (M. g. mexicana) is the rarest in the U.S. — extreme southeastern Arizona and southwestern New Mexico only, with the bulk of its range in Mexico's Sierra Madre.
Pursuing one of each subspecies — the "Grand Slam" — is the recognized achievement. None of those slams come fast.
