Fall Migration Update: November 9, 2007
we end our fall migration season, monarchs are still traveling
to Mexico. Many millions will survive the trip as wind, weather
and good luck allow. How
will this year's population compare to those in past years?

Flash: First Monarchs Have Reached the Finish Line!
October 31, 2007: We just received word that
the first monarch butterflies have completed their long migration!
Here's the news from Estela Romero, who is writing from Angangueo,
Michoacan, Mexico. Angangueo is a small mountain town that's
located in the heart of the monarch overwintering region.

What a week! Monarchs are crossing the skies
of northern Mexico and a cloud of monarchs is moving down
the Texas Gulf Coast. Monarchs were even spotted over
the Gulf of Mexico as they flew over an offshore oil
platform. The first butterflies are expected to arrive at
the overwintering sites any minute, according to our observers
there. Will they arrive by their traditional Nov. 1st date
in time for the Day of the Dead?
The migration's leading edge is approaching
the U.S.-Mexican border at the week's end. Por fin! (At last!)
The butterflies are at least a week late this year in northern
Mexico, says Rocio Trevino. A Texas man made an exciting discovery...a
monarch wearing a tag! Exactly where--and when-- do you think
the butterfly was tagged? Send us your guess!
Texas is the only state all monarchs must cross, and the first
big masses of Mexico-bound monarchs have now arrived. There
are two traditional migration flyways across Texas. Are this
year's monarchs going the right way?
A massive migration across Oklahoma, Arkansas, and Kansas
this week resulted in the most spectacular sightings of the
season. Most miraculous was the mile of clustering monarchs
discovered on Sunday in a sunflower field in Kansas. Just
think...It's the first week of October and migrating monarchs
are still being spotted across the north. Warm weather dominated
much of September, and only scattered frost has occurred.
What might this mean for monarchs?

Monarchs cruised into Oklahoma and the Texas "panhandle"
on the very same day this week. It was a long wait. South
winds blew for almost 10 days in Texas, Oklahoma and much
of the surrounding region where the continent's monarchs are
headed, and progress into the region seemed stalled. This

don't know about the height of monarch flight.

The Atlantic Coast and the Appalachian Mountains are striking
geographic features in the East, and the monarchs encountered
them in full force this week: "People were just standing
and staring," wrote a woman who saw thousands of monarchs
migrating along a NY beach. Also this week, explore an unusual
observation. Why were the monarchs standing in the road?

Monarchs soared into Nebraska over the weekend.
They landed the very same night in the first roosts reported
for the state. This week, take a close look at monarchs
who have stopped in a garden to eat. Where do they find
the food they need, and why must they hurry? Explore the
challenges monarchs face when fall is coming and the flowers

The north wind blows after a cold front passes, and the
strong August 29th system set monarchs sailing in the Great
Lakes region. Did they fly across open water? Also this
week: Why do monarchs form roosts during fall migration?
They migrate alone so why come together at night and how
do they find one another?

migration to Mexico is underway! It seemed
early when the first reports appeared on the map, but the
telltale signs of migration were clear. Monarchs were forming
huge clusters across the north, and flying southward in
"directional flight" an obvious change from the
flitting flight of summer. Find out how, when, and where
to watch fall migration--and please tell us what you see!
Beginning September 1st, weekly
FALL MIGRATION UPDATES will be posted here
every Friday, from September to November. (See schedule
