Monarch Tagging

  • Hillside Prairie Sanctuary 1813 Hillside Road Cambridge, WI, 53523 United States (map)

Registration is now open to SoWBA members!

Southern Wisconsin Bird Alliance's sanctuaries are teeming with wildlife, and in the early fall, that includes migrating monarch butterflies. These beautiful insects are making their way from Wisconsin (or even further north) all the way down to Mexico where they overwinter and rest before starting their journey back north in the spring. This migration is an incredible feat, and one that scientists have been studying for decades.

Monarch tagging is the act of safely catching monarchs, placing tiny stickers with a unique number code in a specific part of their wing, and releasing them to continue on their journey south. In the winter, our counterparts in Mexico look for monarchs with these stickers and record the numbers. The project was begun by Monarch Watch out of the University of Kansas, and is now done throughout the country. SoWBA has been tagging monarchs for many years!

We will teach you how to safely catch, handle, tag, and release a monarch, all in the name of science and love of nature.
