Description:

In 1998 and 1999, we modified 400-kHz passive integrated transponder (PIT) tag equipment previously used in water to detect PIT-tag codes on land from fish captured by piscivorous birds in the Columbia River Basin. Three detection techniques were used: an automated flat-plate antenna dragged over the surface of bird colonies with a four-wheel-drive vehicle, a pole-mounted antenna passed over smaller nesting areas by hand, and manual or visual sifting.
