hatching at ICF, this chick was nicknamed "Caliper" by
caretakers, but her real and only official name is DAR 43-07.
She came from the egg that the Team tried to put into a pair's
to be raised by adult whoopers.
The pair would not "adopt" the egg, so 43-07 was
instead hatched in captivity. She had a difficult time breaking
out of the egg, but she grew to be a good-sized female in the
of the pack.
was released with DAR #39-07 October 30, 2007
on Necedah NWR by adult Whooping Crane #102. They later joined
four other DAR chicks that were still on the refuge. These six
stayed together the rest of the week. They roosted each night
at Site 3 with adult female #102. This DAR group moved around
to other ponds on or near the refuge during the day. They associated
with adult pairs #211/217 and #309*/403 sometimes. Other times
they were with Sandhills, or alone.
chicks 43-07, #39-07,
and 44-07 roosted
with adult #102 on the night of Nov. 5. That's a good sign
that maybe they'll follow her south!

ICF Tracking Team
Migration South: Nov.
6, 2007: The group of 6 DAR chicks joined
#309 and 403 and sandhill cranes at another spot on Necedah
NWR. Several other adult Whooping Cranes and
about 200 sandhill cranes were also nearby. And then the 6 young DAR birds did
a surprising thing: they began migration, all by themselves and with no adult
whooper or sandhill crane to lead the way! The chicks took off in 20 mph NNW
winds under partly cloudy skies. They flew south 214 miles and landed to roost
in a small pond in a harvested cornfield in Peoria County, Illinois. They
resumed migration Dec. 5 after their roost pond became frozen. With tailwinds,
they flew 167 miles and landed to roost in Clinton County, Illinois. (See
December 11, 2007, the six off-course cranes were captured
and moved to Tennessee by the ICF tracking team so they could
easily find cranes to follow south.
But on December
17, DAR females 39-07 and 43-07 flew to Alabama. They stayed until December 23,
when they returned and wandered around the Hiwassee area. Tey
remain in Tennessee.
2008 and First Unassisted Migration North: Began migration
March 16 from her wintering grounds in Meigs
Tennessee along with DAR 37-07, 39-07, 42-07, 44-07, and 46-07.
They roosted for one night in Adair County,
Kentucky and then migrated the next day to Clark County,
March 21st, they continued migration to Fayette County, Indiana.
On March 22, #43-07 died at
that location when she apparently struck powerlines, the greatest
danger to migrating cranes.
