Past, Present, And Hypothetical Methods For Crane Reintroduction And Migration, David H. Ellis
Past, Present, And Hypothetical Methods For Crane Reintroduction And Migration, David H. Ellis
Proceedings of the North American Crane Workshop
In the early 1980’s the technique of releasing yearling parent-reared cranes was perfected with the Mississippi sandhill crane (Grus canadensis pulla). In the late 1980’s, we discovered that hand-reared yearlings could also be released with good expectation of survival in both migratory and nonmigratory situations. In the mid-1990’s, efforts expanded in many directions including (1) the use of various types of motorized vehicles to lead migrations, (2) the release of juveniles one by one into wild flocks in autumn or winter, and (3) the release of adult pairs. Here I outline new and proven techniques and those likely …

Initial Training Of Cranes For An Airship Migration, David H. Ellis, Glenn H. Olsen, Jared Kwitowski
Proceedings of the North American Crane Workshop
We describe the first year of our efforts to train cranes to accept the unnatural stimuli associated with being transported south in cages suspended beneath an airship. All 4 experimental cranes readily acclimated to entering a suspended cage and were trained to accept being jostled while in the cage, even when the cage was transported in the back of a pickup truck. With minor changes, the training protocol is ready for use in an actual airship migration.
