Q. A big exhibition on Theodore Roosevelt is opening this month at the American Museum of Natural History. Does the museum display any animals that T. R. personally shot?

A. It does. Over his life, from his teens until after his presidency, Roosevelt donated many specimens to the museum, which his father had helped found in 1869. Most of them — from bird skins to elephant tusks — are stored away in research files, but at least five animals he killed will appear in the renovated two-story Theodore Roosevelt Memorial when it reopens on Oct. 27, the 154th anniversary of Roosevelt’s birth.

Perhaps the most striking is a snowy owl. Roosevelt, a young naturalist, was studying taxidermy with an associate of John James Audubon by age 12. According to museum records, Roosevelt shot the owl in 1876, at age 17 or 18, near his family’s summer home in Oyster Bay, N.Y., and mounted it himself. He gave it to the museum in 1911.
