A few days ago I blogged about the annual monarch migration. There's a fascinating story in today's New York Times explaining the migration process and what scientists are doing to understand it better. Here are a couple of amazing facts from the article:
"They [monarch butterflies] are one of the few creatures on earth that can orient themselves both in latitude and longitude — a feat that, Dr. Taylor notes, seafaring humans did not manage until the 1700’s, when the clock set to Greenwich time was added to the sextant and compass.
"All monarchs start migrating when the sun at their latitude drops to about 57 degrees above the southern horizon."
Every day, I watch monarch after monarch flying above me, heading south. I love finding out more about what's going on here!
If you're interested in finding out more about research, conservation efforts, and education for and about the monarchs, go to Monarch Watch.
