Highlights: ¡Bienvenidos a México Mariposas Monarcas!

News from Northern Mexico

Monarcas en el noreste de mexico
The migration surged southward during the past week. Monarchs are now crossing the skies of the Mexican states of Coahuila, Nuevo Leon and Tamaulipas, according to reports collected by Senora Rocio Trevino. Monarchs blew across the border in huge numbers last Friday, October 18th and had traveled as far south as Galeana, Nuevo Leon where these snapshots were taken. That southernmost report is only 400 miles from the overwintering sites. Watch the animated map of monarch roosts to see how far the migration advanced in a single week. Do you think they'll reach the overwintering sites by their traditional date of Nov. 1st, in time for the Day of the Dead?

News from the Overwintering Sites

Expecting the First Monarchs Any Minute!
"We think we should see the first Monarchs arriving any minute now," wrote Estela Romero on Thursday, October 25th. "The weather is now deep, blue sky— icy in the mornings and evenings — but very, very sunny during the day. I just met Germán Median here at the internet café and he will go today once more to Ël Cerrito and one or two more points in Angangueo where the monarchs usually arrive first."

Also this week, students describe why Mondays are so special in their small mountain town.

News from Texas

A Cloud Moving Down the Coastal Flyway--and Offshore!
A massive migration is now moving along the Texas Gulf Coast. A cloud of monarchs stretches at least 150 miles from Galveston to Corpus Christi, Texas. People saw monarchs "dropping out of the sky" and a migration that "continued all day long." Migrating monarchs were also seen over the Gulf of Mexico according to a witness on an offshore oil platform 120 miles from the coast.

"The coastal flyway had its first players show up today," wrote Harlen Aschen from the mid-coast on Tuesday, Oct. 23. By Thursday night, reports were popping up on the map with comments like this from Galveston: "I witnessed the most incredible sight this morning and it has continued all day long."

Texas Central Flyway (Near Mexican Border): An Unusual Year?
The first surge across the southwestern section of the Central Flyway was finally noted on October 18th.
Carol Cullar, Director of Rio Bravo Nature Center, has been chasing monarchs in the region, hoping to catch the first wave as the migration leaves Texas. See what you can learn from her observations this year— and what she learned herself:

Monarchs don't stop at the Mexican border the way U.S. weather maps do. Which way do you think the wind was blowing in northern Mexico when this roost was found in Galeana, Nuevo Leon?
