The collection was formed in 1859, beginning with the work of naturalist Louis Agassiz (1807-1873). It is one of the oldest and most extensive natural history collection on display in the western hemisphere.
It’s an animal sketcher’s paradise because there’s a huge collection of skeletons and taxidermy animals on display in glass cases with simple backgrounds.

There’s everything ranging from a whale skeleton to a case of hummingbirds. Because the mounts are old, some of them are a little weird looking or cracking, which adds an odd vibe to the experience.
There’s an exhibit right now on color in the animal kingdom, and another on animal headgear--meaning mostly antlers and horns of wild deer and sheep. Part of the $9.00 museum admission is the Peabody anthropology museum and the world renowned Blaschka Glass Flowers collection.
My sketch of bison is done in watercolor and water-soluble colored pencils in a Moleskine watercolor sketchbook.
