For most Americans, life revolves around turkey for just one day each year: From the making of the stuffing to the basting and the baking, it all leads up to that delectable moment when the golden brown bird graces the Thanksgiving table.

For Tim Oldham Jr., turkey is much more than a daylong affair — it’s a full-blown, year-round obsession.

“I’ve got turkey mounts, turkey beards, trophies — everything turkey,” said Mr. Oldham, a turkey hunter and artist from Newburgh, Ind., describing the lifelike stuffed turkeys and feather bristles that adorn his “turkey man cave.”

“I have to really hold myself back,” said Mr. Oldham, 46, who has won national awards for his decorative calls, the devices hunters use to attract male birds, known as gobblers. “I can overwhelm people because I’m really into it.”
