"A harmonious parade of monarchs were streaming across the sky. I have not seen such a massive arrival in years," wrote Estela Romero on October 30th.

Monarchs arrive at El Cerrito, Angangueo, Michoacan, Mexico on October 30, 2017 by Estela Romero

They’re Here!

The weekend was calm and quiet. On Monday, Estela took her daily drive around town…

“There it was. My first of the season. I could very well see it flying along in such a royal, sovereign way — as if totally ignoring me! A wonderfully strong, bright orange and black butterfly, just like its name: Monarch.”

She continued on to El Cerrito, a hillside above Angangueo where monarchs stop before reaching the nearby sanctuaries:

“I walked into the woods and was simply spellbound. The massive arrival was just taking place. Even at this time of the day (12:30-13:00 hrs), some small clusters were forming. I have not seen such a massive arrival in years.” More…

Fall Migration 2017 Continues!

All week, monarchs were streaming across the skies of northern Mexico, with peak reports from  Nuevo Leon, Tamaulipas, and Guanajuato. Migration was strong along the Gulf Coast in Texas, Louisiana, Mississippi and Florida. There were still large roosts on the Atlantic coast and as far north as Canada!
