I know I posted about Journey North just last week, but we’re having so much fun with it that it’s worth mentioning again. We signed up for email “migration updates,” and every day or so we get an exciting email about what’s been sighted where. This week, barn swallows arrived in Louisiana, while the monarch butterflies (who have not yet left their wintering grounds in Mexico) suffered an attack by gale-force winds that whipped them out of their sheltered resting-places in the trees.
“It was relatively easy for us pedestrians to pick our way amongst the fallen butterflies,” writes Dr. Bill Calvert from Mexico. “But the horse carrying passengers to and from the colony didn’t bother. Some butterflies were crushed. Those that weren’t were exposed to increased risk of predation at night by the black earned mouse, and increased possibility of freezing if cold weather impacted the area. But the majority of the colony had moved down into the shallow headwaters of the Zapatero Canyon where they were protected from the high velocity winds.”
