• Tim Knight, a biologist and web editor, prepared most of the animal facts pages using personal observations, field guides, books, journals and reliable online resources. Typically, three to ten sources were used to develop each fact sheet.
• The Spanish version of the animal facts were prepared by Waterville high-school students and reviewed by their teacher.
• Dave Lester created the distribution maps and related web pages.
• Karen Dvornich reviewed the animal facts and distribution maps for accuracy.

  Special thanks to Alan and Elaine Wilson of Port Coquitlam, British Columbia who generously provided many outstanding photos via Natures Pic's.

With a few exceptions, NatureMapping web pages and fact sheets are fully sourced, bylined, and dated to provide authoritative references for personal, journalistic, and scholastic use. Different stylebooks, mainly the Chicago Manual of Style, the MLA Style Manual, and the Associated Press Stylebook, have different citation styles. For most purposes, we recommend using the following format (shown with a sample essay) to cite NatureMapping:
