Buttons, a young female passenger pigeon was shot in Pike County Ohio in March 1900. Unaware that she was the last an armature taxidermist preserved the specimen noticing the scarcity of appearance in later years. During the preservation the taxidermist came up short on glass eyes, Victorian shoe buttons where used instead. Hence the enduring name attached to the last representative of a lost North American species. This model is held by the Ohio History Center in Columbus Ohio, regrettably there is no link on the website however there is a blog post that notes Buttons presence in the collection.
Many thanks to Buttons curator Dave Dyer.
