Before sunrise today, the calm air changed
as a cold front moved through and sent winds out of the WNW. Blowing
at 6 mph
on
the surface and 25 mph aloft, they set the leaves to rustling. Yesterday's
jumping-for-joy excitment over a great flight with (NO crates needed!)
will not happen today. But the cranes are happy pecking and poking
at
pumpkin parts. How are winds and weather central to the migration?
Will the weather where you live today affect your choice of activities?
Did
you see the flight on the TrikeCam mounted
on Chris's wing? If not, review
archived footage here. And see the
CraneCam views of the birds in their pen at Stopover
#3.

Today's
Journal Question: (a) How
many miles have the young birds covered so far?
Of all the days of migration, which do you think
has been the best day and why? (b-for-bonus) Yesterday
they took off at 7:26 and landed at 8:21. How
long did they fly? What
facts above will help
you figure out the speed (miles per hour) of
yesterday's flight? Approximately how fast did
they fly to cover the distance?
