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 …
