Highlights
Monarchs
Enter Two New States
The leading edge of the migration moved into two news states during
the last week. It's time to add Louisiana and Arkansas to your
list. Play the animated
map back and forth between this week and last. What changes
do you notice? Which direction(s) has the migration moved so far
— north east west?
GONE
from the Colonies!
Dr.
Lincoln Brower sent the word on Saturday, March 18: "My colleagues
in Mexico called from Angangueo tonight and told me that the monarchs
have all left the Sierra Chincua colony (except for those
clustering on two trees), and have all left the Cerro
Pelon colony (but those clustering on 10 trees)." So, while
our map shows the leading edge of the migration, it's peak
migration now across northern Mexico.
Scientists
Following Monarchs Across Mexico
Little is known about the route monarchs travel so this
year two Mexican scientists are following the monarchs north.
Dr. Brower explains the importance of the study:
"We
hope to find the migratory path and see what species of flowers
the butterflies are nectaring on along their route to Texas. We
also want to know whether they are seeking water holes along the
way," he said.

The
very same week that monarch butterflies arrive in Texas each spring, one
of North America's favorite birds also appears on the scene. The first
Ruby-throated hummingbirds arrive during the first week of March, just
as the monarchs do. Although one is a bird and the other a butterfly,
they are heading north for the same reasons. What can we learn by comparing
their migrations? Let's see what one migration makes you wonder about
the other!
