Standing Down in Green County, WI
Winds are 10-15 MPH out of the right direction and the temperature is a just-right
42 degrees F. So why is the migration standing down? If the winds are blowing 10-15
MPH on the ground, chances are they are much faster at higher altitudes. Heather
told Journey North: "We can fly if there are winds on the ground at 5 MPH coming
from the right direction. That would provide a nice, gentle tailwind. But at the
current wind speed, the tailwind would be more like a blast. It's just too risky.
AND we might just end up getting blown all the way to Mexico!"

But there's more to the story. Remember the first two drop-outs in Sunday's less-than-perfect
flight to Green County? They were flying at a low altitude while approaching the
tree-filled ridge. Because of this, the birds actually clipped some tree branches
and dropped out, landing in the forest below them. Dan Sprague of USGS
Patuxent Wildlife Research Center and Kelly Maguire of the International
Crane Foundation were able to track and capture these two after two hours of
effort. Crane #1 had a cut on the inside of her thigh, no doubt caused by a tree
branch. She was taken to project veterinarian Dr. Barry Hartup at ICF, who gave the
birds stitches to close her wound. Dr. Hartup ordered two days rest and antibiotics
for Crane #1. Then she was transported to join her cohort in Green County, where
Dan had already delivered the other reluctant youngsters. As Heather said, "If
the birds only knew what these costumed humans go through to make sure they all arrive
at the same location!" (You'll want to record these events on your chart.)

- Take a close look at the photos in today's Highlight. Which ones can you identify
by banding codes? Write a descriptive
paragraph about one of the photos. Write a clear topic sentence and then choose words
that help create a snapshot, as though you are describing the scene to someone who
cannot see but wants to know every detail.
- Read this excerpt from Heather's
report (see October 21 entry) about the troubled flight to Green County on Sunday.
Then write your thoughts about this question: What are some factors that help ensure
a good take-off?
To start with, the take-off was hindered by three birds who seemed reluctant to
exit the doors of the enclosure because there was a small stand of trees that they
would have to walk next to before they could join the waiting aircraft on the grass
strip. Once the entire group was out, some birds were already airborne and as the
three trikes lifted off, three other birds decided to turn back and join the two
costumed handlers who had not had time to hide inside the pen because they were trying
to ensure all of the cranes made it out of the pen.
