As the butterflies prepare to depart for migration, tags and wings are being recovered for clues about where the monarchs originated last fall.

Get Ready for Migration!
On March 1st, Estela sent this exciting news:
“I need to tell you while driving from Querétaro to Angangueo we saw perhaps a couple dozen monarchs flying north! They were already 80 km (50 miles) from the sanctuary!”
