As wild animal tracking systems, positioning systems with GPS and PHS technologies have advantages against conventional technologies in terms of accuracy etc.' On the other side, these systems require more power consumption and this results in a device weight increase. When devices attached to animals, the weight of them should be limited. Therefore, in designing a tracking system, the number of position fixes per hour, power consumption, duration of use, battery selection, total weight should carefully be determined because these elements have trade off relationship. Taking this relationship into consideration, we developed tracking devices with the PHS technology and applied them to crows in urban areas, which showed effectiveness.
