IN PURSUIT OF WILD JOURNEYS: TRACKING LONG DISTANCE BIRD MIGRANTS 조류의 장거리 이동 추적: 야생의 여정을 따라 (original) (raw)

Abstract

A number of possibilities exist for tracking the sometimes even global journeys undertaken by migrating birds. Birds fitted with radio transmitters can either be located from the ground or from aircraft (conventional satellite tracking), or from space. Alternatively, positional information obtained by onboard equipment (e.g. GPS units) can be transmitted to receivers in space. Using these tracking methods has provided biologists with a wealth of insight into the migration routes, stopovers and other behaviours in long-distance migrants that are otherwise very difficult to follow. This knowledge has important implicat ions for e.g. conservation and understanding disease transmission and effects of climate chang e. The weight of satellite radio transmitters complicates study of the majority of bird species, but the weight is likely to be greatly reduced in the near future.
