Why
do Monarchs fly to Mexico from across the continent? |

"I have a series of pictures that tell a neat story of how the monarch's forests capture moisture," begins Dr. Brower. "The condensation that occurs in these high altitude Oyamel forests is crucial for the butterflies’ overwintering success in Mexico. Yet, while the moisture provides critical hydration for the butterflies, it can also kill them…Here is how all this happens." See Dr. Brower's Slideshow! >> |

Each week we'll challenge you with a Journal Question. Today:
- Describe one way monarchs find water at their winter home in Mexico. How can this also be dangerous for them?
Take a look at Dr. Brower's slide show and record your thoughts in your Journal, Surviving the Winter in Mexico. >>
Dr. Lincoln Brower has studied monarch butterflies for over 50 years. Yesterday he left for Mexico. He and his colleagues will fly over the entire Monarch Butterfly Biosphere Reserve to search for monarch colonies.
"The big question is, why are they so limited when there seem to be many mountain valleys in which they could overwinter? The implications are astoundingly important," he said.
