The overwintering season started a bit earlier this year! Since the last days of October, hundreds of butterflies could be seen from the roads around the MBBR flying towards the forests. This spectacular arrival continued for two more weeks and ended the weekend of November 13-14 when the colonies were already established. The colonies will be officially open to tourism until November 27 in Sierra Chincua, El Rosario, and La Mesa and Cerro Pelón will remain closed. In the photo below, taken in the Monarch Reserve’s buffer zone by Isabel Ramírez, we see some monarchs on Buddleia flowers making a last stop before heading to the overwintering sites.
