Specifications include, but are not limited to: bjective 1: Sage-Grouse Capture and Radio-GPS Telemetry•Capture and mark sage-grouse using spotlighting techniques (Wakkinen et al. 1992,Giesen et al. 1982) during the fall and spring of each year.•Captured birds will be aged, weighed, sexed, banded, measured including total tarsus,culmen, wing chord and primary 1,9,10, and fitted with either a necklace-mounted very high frequency (VHF) radio transmitter with an activity sensor (Sveum et al. 1998), or arump-mounted GPS transmitter (the decision to fit either a GPS or VHF transmitter will bemade randomly for each bird).•Data from the GPS transmitters will be downloaded from the ARGOS website and post-processed using various computer software and quality control measures. However, GPStechnology is costly, and use of additional VHF transmitters will allow us to increase oursample size for demographic analyses.
