Nesting Activity Budgets And Antipredator Behaviors Of Mississippi Sandhill Cranes, Jerome J. Howard, Rose Butler Wall, Lauren Billodeaux Mowbray, Scott G. Hereford
Proceedings of the North American Crane Workshop
We studied activity budgets and antipredator behaviors of Mississippi sandhill cranes (Grus canadensis pulla) to determine if parental behavior influenced nest outcomes. We used infrared motion-activated cameras to capture behavioral sequences from 21 nests over a 2-year period. Overall activity budgets were similar among crane pairs regardless of nest outcome. Specific activity patterns did predict nest outcomes; pairs at unsuccessful nests spent more time away from the nest and more time manipulating nest contents than successful pairs, while pairs at nests that were lost to predation cooperated poorly and started the nest a month later on average than …
Protocol And Results From The First Season Of Captive-Rearing Whooping Cranes For A Non-Migratory Release In Louisiana, Glenn H. Olsen, Jane N. Chandler
Protocol And Results From The First Season Of Captive-Rearing Whooping Cranes For A Non-Migratory Release In Louisiana, Glenn H. Olsen, Jane N. Chandler
Proceedings of the North American Crane Workshop
The principal historic range of the whooping crane (Grus americana) consisted of the tall grass prairies and wetlands of southwest Louisiana, Texas, and parts of Mexico (Allen 1952). Whooping cranes migrated there from Illinois, Iowa, Minnesota, Dakotas, Manitoba, Saskatchewan, Alberta, and breeding grounds of the remnant flock in and near Wood Buffalo National Park, Canada.
