Proceedings of the North American Crane Workshop
We review the history of tracking cranes with satellite telemetry and identify some of the difficulties in designing satellite transmitters and harnesses for cranes. Miniaturization of these transmitters and a plethora of harnessing experiments since 1989 allow us to recommend limited application of this technology to all species of cranes. We are still uncertain, however, if cranes harnessed with satellite telemetry devices are able to reproduce after migration. Because of this uncertainty, we urge caution in the use of this technology, especially with breeding adults in severely endangered popUlations. This manuscript also describes continuing research needs.

Proceedings of the North American Crane Workshop
Satellite telemetry is a developing technology for the study of crane migration. A greater sandhill crane (Grus canadensis tabida) was tracked by satellite from Florida to Michigan in March 1989 (Nagendran 1992). This note reports the second attempt to use satellite telemetry to follow crane migration. In 1989 -90, tests of various harness and backpack designs for satellite telemetry transmitters (PTT's) with free-flying and confined sandhill cranes led to a 4-strap design (see Olsen et al. 1992) that was accepted for field testing. Through a cooperative effort between the Patuxent Wildlife Research Center (USFWS) , International Crane Foundation, …
