Western Monarch Thanksgiving Count

Help researchers take census of winter Monarch butterflies.
Count monarchs at overwintering sites around Thanksgiving.

The Western Monarch Thanksgiving Count (WMTC) is a citizen-science project designed to census the size of overwintering monarch colonies. As the name implies, it is conducted over a three-week period around the (American) Thanksgiving holiday in November and December by a large number of volunteers. The project is currently coordinated by Mia Monroe, Candace Fallon, and Emma Pelton with the Xerces Society for Invertebrate Conservation.
