Field reports from California, Arizona

April 10, 2025 by Gail Morris, Southwest Monarch Study coordinator

Monarch sightings continue to increase along the California coastal regions from the southern border all the way to Oakland, as well as in the Sonoran Desert in Arizona up to the greater Phoenix area. Remigrants will continue to work their way north and east through the West the next few weeks until they reach the end of their lives. But the next generation will soon appear and continue streaming to the Canadian border by summer.
