Teaching cranes to migrate
Article Abstract:
Modified migration and release techniques of captive-reared whooping cranes can improve their survival. The crane chicks are trained to follow the caretaker while walking, driving or flying an ultralight aircraft, and to forage independently. They are then taught to migrate along a pre-specified route and led to a specific wintering area, where they can interact with other wild cranes and learn appropriate survival behavior. The proposed route begins in southeastern Idaho and goes through Utah, Colorado and New Mexico, to Bosque del Apache National Wildlife Refuge.

Satellite telemetry solves eider mystery
Article Abstract:
Satellite telemetry studies reveal that the spectacled eiders congregate in dense flocks in areas far away from the land, and spend their winters in the pack ice in northeastern region of St. Matthew Island, Alaska. The location of molting and wintering areas of these endangered arctic ducks are difficult to study without using satellite telemetry, as these areas can be spotted only if the survey plane is very close to the flock. The satellite transmitters used for studying these birds are placed in the peritoneal cavity.

Spectacled eider mystery is solved
Article Abstract:
The spectacled eider, an endangered bird species, spends the winter season in the Bering Sea south of Saint Lawrence Island, where they jam themselves in tiny holes in the pack ice to keep warm despite the minus 20 degree Fahrenheit temperature. The birds then return to tundra areas in the summer to breed. Biologists of the Fish and Wildlife Service and the National Biological Service obtained these information by using satellite-track technology.
