Above the galleries are millions of scientific specimens.

Our scientific collections contain some of the largest shell and bird collections in the country.

The specimens come from all over the world — and from the local region. As a whole, the scientific collection serves as a record of biodiversity on Earth. Our staff builds, protects, and preserve our collections with the help of volunteers. Our scientists conduct a variety of research projects, and scientists from around the world also use our collections for their research.
