Crane 714 was killed March 30, 2008, the victim of a predator while on a spring migration stopover. Crane 735 was alive and well in July 2008, but unable to fly from an injury received during final health checks in Florida after her first migration. She was transported back to Wisconsin in spring, but, unable to fly, removed from the population to a captive breeding center to become a parent bird. |

Year 2006 |
One chick from the flock's first wild-hatched pair died at 4 months of age, before its first migration. Seventeen of the 18 juveniles at the Chassahowitzka NWR pen site died in the early morning of February 2, 2007 as a severe thunderstorm with high winds, resulting high tides and heavy rain, passed through the area: #601, 602, 604, 605, 606, 607, 608, 610, 611, 612, 613, 614, 618, 619, 620, 622, and 623. DAR #32-06 was killed by a predator (probably bobcat) the end of January, 2007. Her remains were discovered Feb. 6, 2007. DAR #26-06 was killed (likely by a predator) on April 13, 2007 at a migration stopover in Indiana. Crane #615 was found dead the end of April on his territory at Halpata Preserve in Florida before he could leave on migration. No signs of predation and no clues as to cause of death. A necropsy is being performed to determine how he died. |

Year 2005 |
Crane #515 died September 13, 2005 from colliding with the plane wire during training (before the chicks and ultralights left Wisconsin on migration). Crane #526 died on Day 27 (Nov. 9, 2005) of the southward migration, found dead in the travel pen after a fight with another crane in the pen. Crane #522 died sometime between July and September, 2006. His remains were discovered Oct 28, 2006 when his signal was detected during aerial tracking. Crane #521 died in her wintering area in Citrus County, Florida, between February 9 and 12, 2007. Her remains were discovered Feb. 20, 2007. Bobcat predation is suspected. Crane #523 died in Florida in April, 2007, likely from alligator predation. Crane #510 died in Wisconsin in July, 2007, killed by a predator when she was molting and flightless in a drought-stricken wetland. Crane #32-05 died in Wisconsin sometime during the first two weeks of July, 2007, killed by a predator at the edge of a dried-up pond. Crane #502's completely intact body was found August 20, 2007 in a few inches of water. Experts believe she died on August 16 or 17, before the rains came and the marsh was likely dried up. Her carcass will be given to the USGS National Wildlife Health Center for necropsy to determine cause of death. Crane #503 was missing since May 2007 and not found until April 2008 when faint radio signals were detected from the territory of her and mate 507. The remains of both birds were found there on April 20, 2008. Death had likely occurred shortly after they were last observed in May 2007. Crane #507 was missing since May 2007 and not found until April 2008 when faint radio signals were detected from the territory of him and mate 503. The remains of both birds were found there on April 20, 2008. Death had likely occurred shortly after they were last observed in May 2007.

died Dec. 11, 2004 of Eastern Equine Encephalitis, one day before
arrival at the Florida pen site with her group's ultralight
migration. Crane #417 died in June 2006, the victim of a Wisconsin predator. Crane #407's decomposed but otherwise intact carcass was found on September 13, 2007, in dry sedge marsh at his Wisconsin territory on northeastern Meadow Valley Flowage.

Year 2003 |
Crane #314 was fatally injured during summer aircraft training before the first migration. Crane #319 was found dead in Michigan in August 2004, likely killed by a coyote. Crane #305 was killed in South Carolina during 2004 fall migration, likely by a bobcat. Crane #304 was found dead Oct. 27, 2005 at Necedah. No signs of trauma. Crane #302 was found dead July 17, 2006 in Monroe County, WI, likely the victim of a predator. It was the first death of a member of a breeding pair of whooping cranes in the new Eastern flock Crane #306 was found dead on his Wisconsin territory on July 12, 2007. He was flightless due to molt (loss and regrowth of feathers), which was about 80% complete. He was killed by a predator, apparently a large mammal, in a dried marsh in this drought-stricken area. Tracking data indicated that he died on or about July 6. Crane
#301 was found dead September 28, 2007 at Necedah.
Tracking data indicated that death probably occurred on the
night of 25 September, and her carcass was intact. Cause of
death is unknown and a necropsy will be performed. |
