hatching at ICF, this chick was nicknamed "Plumb-bob" by
caretakers, but her real and only official name is DAR 41-07. She
seemed short and sqat, almost bowlegged, as she started growing.
She was low girl on the totem pole. She used to be aggressive
but she got VERY scared one night. Marianne thinks that a bear
might have come around and terrified her.
41-07 was released on October 30 on Necedah NWR along with DAR
37-07, 40-07, and 44-07. She flew with #37-07 to roost on the
Sandhill roost on her first night of freedom.
chicks #42-07, 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 teamso they could
more easily find adult cranes to follow south. DAR 42, 37,
remains in the area around Meigs County,
2008 and First Unassisted Migration North: Began
migration March 16 from her wintering grounds in Meigs Co,
Tennessee along with DAR 37-07, 39-07, 43-07, 44-07,
and 46-07. They made good progress, roosting for one night
Adair County, Kentucky and then resuming migration the next
day to Clark County, Indiana. On March 21st, they continued
migration to Fayette County, Indiana. PTT
data (satellite data) for DAR 39-07, 44-07, and 46-07 indicated
they finally moved again on April 16. The group proceeded
to Tuscola County, Michigan for several weeks. They were
still there as of mid May, although some members of the group
returned. On June 2 trackers traveled
to the cranes' location to try to capture them all and bring
them back to Wisconsin. Only one crane, #37-07, was successfully
captured and returned. The tracking team returned June 10
and caught 42-07 and 2 others and brought them back to Wisconsin!
She wandered all summer, and spent time in southeastern Minnesota.
PTT readings in September showed
she was still there, along with males #703 and
707, and female 39-07 (DAR).
2008: DAR #42-07's group headed south Nov. 15 from
Minnesota. A high-precision PTT reading for DAR female #39-07
( in the Minnesota
group with #707, 703 and DAR 42-07) indicated a migration stop
near St. Clair County, Illinois, on the night of November 16. This
group wintered in Lowndes County, Georgia.
Spring 2009: PTT
data from DAR 39-07 (and presumably her group with #703, 707, and
DAR 42-07) put her (and probably the others) in Madison County, Alabama
on the night of March 19 and in Marshall County, Kentucky on the
night of March 22 as they migrated north. She was
confirmed back in Wisconsin by March 26-27. In May,
the "mystery bird" often seen flying with DAR #42-07
was finally identified. When the two birds
moved onto a private cranberry
farm, Eva and Sara got permission to come onto the farm. The two
birds were standing in one of the cranberry beds. Observing from
a distance, Eva could read the color bands on the mystery bird
and identify him as
#316. It is exciting that these birds have become a pair.
DAR 42-07 remained
in the core area with #316 until late September when their pair
bond ended. Then she began associating
with DAR 27-06 in early October. The newly formed pair remained
at Quincy Bluff in Adams County, Wisconsin, thoughout October.
She was reported in Dane County,
Wisconsin, from November 15-25 with 27-06 (DAR) and #524.
They were no longer at this location on November 26 and
completed their migration in Morgan County, Alabama.
2010: Crane 42-07 (DAR) began migration from
male 27-06 (DAR) and #524 after March
#524 were found back in Adams County during an aerial survey
on April 5.
2010: 42-07 (DAR) and #524 were confirmed at their wintering
area on Wheeler NWR, Morgan County, Alabama, on November 29.
2011: 42-07 (DAR) and #524 were
3 and did
winter location. They were back in
Adams County, Wisconsin by March 21. The pair
nested for the first time and began incubating
on April 24. The nest failed on April 29 but
two fertile, viable eggs were collected.
news came on June 13 when the
carcasses of this breeding pair were found on their Adams County
territoryby ICF Field Ecology Intern Mike Wheeler. Both carcasses
were sent to the USGS National Wildlife Heath Center in Madison,
Wisc. for necropsy. The suspected cause of death for the female
was septicemia, and analysis of lab cultures and tissues is pending.
(The carcass of male #514 was too decomposed to determine the
cause of death and tissues were unsuitable for
