Mexico | Migration of the Monarch Butterfly with Biologist Paulette Bierzychudek

Mexico | Migration of the Monarch Butterfly with Biologist Paulette Bierzychudek

About this trip

One of the most amazing phenomena in nature is the annual migration of Monarch butterflies (Danaus plexippus) southward from their breeding grounds in the United States and Canada to overwintering sites high in the mountains of southern Mexico. Hundreds of millions of Monarchs fly along the Gulf Coast, or across the Gulf of Mexico, to eventually reach the belt of high volcanic mountains which stretches across the southern end of the central Mexican plateau. At about a dozen isolated places within the high-altitude forests of this zone, Monarchs pass the winter in aggregations that can exceed 2 billion individual butterflies. Stand amid the fir-covered mountains and witness this awe-inspiring spectacle firsthand as the monarchs flutter, dip, and swoop overhead.
Explore with Lewis & Clark

Highlights

  • Hike or ride horseback to two different monarch reserves in Michoacán, where millions of individual monarch butterflies gather.
  • Photograph the dramatic colors of the butterflies as they hang in clusters from the trees, drink from streams, feed on wildflowers, and soar in the air above.
  • Visit the pyramids at Teotihuacán, one of the most architecturally significant Mesoamerican sites of pre-Columbian times. 
  • Spend time exploring colonial Angangueo, which was once a mining town but now derives most of its livelihood from butterfly ecotourism and agriculture. 
PLEASE NOTE: Participants are required to be fully vaccinated against COVID-19.

Meet your leaders

Paulette Bierzychudek, Expedition Leader and Sr. Professor of Natural Sciences

Paulette is a population biologist, working in areas of ecology, evolution, and conservation and restoration biology, particularly of terrestrial plants and insects. Nature is her inspiration, constantly asking “why” about the things that she sees in the natural world. Paulette’s research spans questions like how organismal traits evolve, what factors make populations change in size, and how humans can successfully coexist with wild species. She has worked in eastern U.S. deciduous forests, the alpine meadows of Colorado, the southern Californian desert, tropical habitats in Costa Rica, and of course in the Pacific Northwest.

Her scholarly interests include investigating the return of native plants after removal of English ivy; restoring habitat to promote the recovery of the threatened Oregon silverspot butterfly; understanding the evolution of a flower color polymorphism in a desert plant.

Dr. Bierzychudek advises students in both Biology and Environmental Studies. She has undergraduate degrees in botany and in zoology from the University of Washington in Seattle, and a PhD in ecology and evolutionary biology from Cornell University. Paulette has been teaching for 41 years. She is an avid bicyclist and backpacker, recently traversing the alpine regions of Europe with her partner Gary Reiness.

Gary Reiness, Traveling Partner and Professor Emeritus

Gary Reiness is a neurobiologist whose research focused on development of the vertebrate nervous system. He also has had a longstanding interest in ways to enhance the teaching of science. In retirement, Gary has been working with the Partnership for Undergraduate Life Sciences Education to help colleges and universities around the country to improve the teaching of science. Dr. Reiness came to Lewis & Clark College in 1994 as Professor and Chair of Biology and recently retired. He was educated at Johns Hopkins University (BA), Columbia University (PhD), and Harvard Medical School and the University of California at San Francisco, where he held postdoctoral fellowships. He is a Fellow of the American Association for the Advancement of Science.

Mexico City

Angangueo

Feb 22, 2023

This morning you will depart for the colonial town of Angangueo, located high in the mountains in the state of Michoacán, about 100 miles west of Mexico City. Upon arrival in Angangueo check-in at Hotel Don Bruno and have lunch there. This afternoon take a walking tour through town with resident and monarch guide, Estela Romero. Founded in 1792 the town served as a main mining center providing wealth for the area. Today the town derives its income from butterfly tourism and agriculture. As you explore the cobblestone streets Estela will share sites of interest and the importance of butterfly conservation to the town. After dinner at the hotel gather for a briefing to help prepare for the next day.

Angangueo

After breakfast, ascend into the mountains to approximately 10,000 feet elevation to visit Sierra Chincua, one of several nearby Monarch sites. The day will start with a hike up to the reserve entrance. Horses are available for rent as an option for this portion. Once at the entrance to the reserve, continue up the mountain on foot until you reach the site where the butterflies are roosting. The hike is uphill but you will be able to walk at your own pace and stop and rest as needed. The remainder of the afternoon entails walking around the butterfly site on your own and photographing and watching butterflies independently. A boxed lunch will be provided to eat at leisure. Bathroom access is at the base of the mountain and can be reached by walking or renting a horse. There are also vendors at the base selling food, beverages, and local crafts. The site is typically shaded so remember to dress in layers due to high elevations. Late in the afternoon, return to Hotel Don Bruno for dinner. Evening briefing.

Angangueo

Feb 24, 2023

Today visit El Rosario Reserve to see your second Monarch colony and the one most generally accessible to the public. The journey begins with a hike or you can rent a horse to journey up to the site. This large overwintering colony normally contains well over 100 million adult Monarchs and has an excellent trail system winding through the fir-covered slopes on which the colony is located. Additionally, there is a nearby stream where the butterflies may fly at midday to drink water. Have a simple picnic lunch while enjoying this spectacular phenomenon and watch the butterflies go through their daily cycle of activities. At this time of year, they may take flight for an hour or more to secure water, nectar, etc., before returning to their roost on the tree limbs or trunks. Please be prepared to be independent today during butterfly watching. In the late afternoon, return from the mountains to the picturesque colonial town of Angangueo. You will have free time to enjoy the hotel gardens, walk and photograph the interesting scenes and people in this beautiful town, or to just relax.

After breakfast, depart for the Mexico City area and the pyramids at San Juan Teotihuacán. After a delicious lunch near the pyramids, you’ll have the afternoon to explore this world-famous archaeological site, which covers 32 square miles and contains many structures including two large pyramids. The Pyramid of the Sun, at a height of more than 200 feet, is one of the largest structures created in the pre-Columbian New World. After time to explore the ruins on your own, return to your hotel located on the Zócalo and get ready for a farewell dinner at a local restaurant.

Depart

Feb 26, 2023

This morning you will be transferred to the airport for your flight home. Check out is at 12:00 pm. Breakfast will be included depending on your departure time. Please be aware that you need to be at the airport 3 hours ahead of your scheduled departure flight time. This goes for the flight to Mexico as well as on the way back. Please pay careful attention when you book your return flight as a 7:00am departure from Mexico City means that you will need to have to wake up at 3:30am to get to the airport by 4:00am. If you choose to make an early morning booking there is no problem in terms of getting you to the airport on time, but we want you to be aware of the 3 hour check in time.
