FINAL Migration Update: November 11, 2010 | ||||||||||
We ushered the monarchs across the continent, and together we told their story. They flew overhead, rested overnight, and feasted on flowers as they traveled. The monarchs are arriving in Mexico now, and we end the migration season with a key question: How many monarchs made it to Mexico, and how is the population faring? This Week's Update Includes:

The Data Everybody's Waiting For... This chart shows the data scientists have collected over the past 16 years. Notice last year's measurement. The population was the smallest ever recorded in 16 years of keeping records! What will the scientists find this year? Scientists are waiting with great interest to see what this year's results will show. The measurements made in Mexico are the most reliable estimate we have of the size of North America's monarch population. Like a health check-up or a report card, the results tell us how the monarchs are doing. Mexican biologist Eduardo Rendon of the World Wildlife Fund is the scientist who will lead the team. He will share his data with us when Journey North begins in February. (Watch for our first update on February 4, 2011.) Any Predictions? Here's what we noticed about this fall's migration: People across the north said they saw lots of monarchs this summer. The breeding season seemed productive. When the migration season began unusually high numbers of monarchs were reported, especially at roosts in the Great Lakes region. However, by the time the migration reached Texas and northern Mexico, the observations people reported were not unusually high. In fact, they were somewhat lackluster. So where did all of the monarchs go?
Nobody knows answers to these questions, but the observations citizen scientists contribute each fall broaden understanding. Thank you for sharing your own observations! Still Seeing Monarchs? Please Let Us Know! How long will monarchs continue to vacate the north? Tell us what you see! These observations are valuable, so please help us document when and where monarchs are present. |
