Estela Romero and Ellen Sharp provide updates from monarch sanctuaries in Mexico. Farther north in the US, many monarchs remain on their journey. Out west, Gail Morris reports on the final leg of migration.

 

End is in Sight

This week monarch sightings were limited to coastal California and the southern deserts of Arizona after a recent cold spell that dropped temperatures below freezing in the higher elevations of the region. Despite the low temperatures, small pockets of rabbitbrush and other flowers were still available as limited nectar resources to monarchs on the final leg of their migration journey.
