Grouse did not use the TRA in 1982. Sage grouse fed at the TRA primarily in the early morning and late afternoon and evening periods. Home range estimates averaged 109 ha for adults using the TRA in 1981 compared to 74 ha for juveniles.

The timing of brood breakup and individual dispersal movements was determined for members of 2 broods. Brood breakup and dispersal were two distinct occurrences. Radio-marked brood members did not exhibit synchronized dispersal and did not associate during dispersal. Movements from TRA averaged 10.7 km for juveniles and 9.4 km for adults.
