Migration: Maps and Questions
Off! Flying, Resting, and Refueling
Welcome to Journey South's fall migration season! The monarchs are on
their way to Mexico and excitement is in the air. We hope you'll report
your sightings. Watch for monarchs that are flying in
"directional flight," resting at overnight
roosts, or refueling at flowers in fields, gardens, or

It's only August, but people are reporting clear signs of fall monarch
migration. After watching carefully, they have noticed changes in the
numbers of monarchs they see and changes in the monarchs'
behavior. Here are some signs of migration people have
first overnight roosts of the season were reported during the
past 10 days in Minnesota, Wisconsin, Michigan and Iowa. Overnight temperatures
dropped into the 40's last week in the Upper Midwest, and that was when
the reports of roosting monarchs occurred. (Monarchs only migrate during
the day. They cluster together in trees for the night.)

of directional flight have been reported for over two
weeks now. Most unusual was a report from Oklahoma of southbound migration
at an amazing rate of 46 monarchs per hour--in August! This is about
a month before we expect to see such a strong pulse of migration there.
You can read
more first-hand observations at the link below. Think about these questions:
- What evidence
do the observers provide that the monarchs they see are migrating?
- How do
the observers try to measure the changes they see in monarch numbers

What kind of observations does Journey North collect and how are
they important? Students explore these questions as they read and
analyze authentic migration sightings. They discover that detailed
reports are essential in a scientific study of monarch migration.
Students apply their learning by writing their own "Practice
Reports." Finally, they learn how to report monarch sightings
to Journey North by submitting their practice reports to the live
"Practice Report" map.
