Capture and Banding Mist net on singing grounds April and May 2008 Applied transmitters and leg bands Obtained locations and monitored survival
7
Monitoring Monitor woodcock 2-3 times/week to obtain location Conducted singing ground counts Conducted avian point counts Document use by other High Priority Avian Species in BCR
