Monarch butterflies are rebounding after three years of significant drops.
Chip Taylor of Monarch Watch at the University of Kansas says the number of Monarchs wintering in Mexico could be two to four times more than last year. Monarch Watch organizes tagging to track the migration of the butterflies.
The Wichita Eagle reports that favorable weather seems to be the reason for the improved numbers.
The butterflies have been thick the past couple of weeks, but a weather front may have lifted them on their way by now. Wichita naturalist Jim Mason says Monarchs look for northerly winds to help them migrate more easily.
