Texas
Central Flyway:
The week began with many sightings but little progress southward.
Then, the wind finally shifted to the north and the migration's
leading edge advanced to within 75 miles of the U.S./Mexican
border. Por fin! (At last!) because the migration is at
least one week late in northern Mexico.
News
From Northern Mexico:
"Estoy otra vez desconcertada con el paso de las monarcas,
igual que el año pasado, son muy pocas las mariposas
que se observan," reported Rocio Treviño on
Wednesday, October 17th.
Rocio
lives about 200 miles south of the monarch's border crossing.
Traditionally, the migration reaches her home in Saltillo,
Coahuila by October 12th. Why does she say that date is
so easy to remember? Try reading her message in Spanish

Monarch Discovered!
In his back yard in Grape Creek, Texas, Mr. Alley discovered
a tagged monarch butterfly. He took its picture so carefully
that you can even read the number on the tag!
Atlantic
Coast:
On the same day that south winds stalled the migration in
Texas, north winds provided perfect migration conditions
on the Atlantic Coast. On the beaches and dunes from New
York to Virginia, people witnessed the season's most spectacular
pulse. Watch the animated map and see how monarchs appear
to have blown to the coast over the past few weeks. (Or,
does the map show more monarchs because there are so many
people on the coast? This is a variable we must always remember
to consider!)

From the Finish Line in Mexico:
