MIGRATION OF NORTH KINGS DEER METHODS AND MATERIALS 159 Trapping and Marking Forty-five deer were trapped or otherwise captured on summer and winter ranges. Trapping on the winter range was most successful during December and January using Clover traps (Clover 1956) baited with mistletoe (Phoradendron sp.). Summer range trapping was difficult until the Stewart Modified Corral Trap (Rempel and Bertram 1975) was developed which was efficient for capturing deer around salt licks in early to mid summer. Tranquilizing was attempted on free ranging deer but was largely unsuccessful. Young fawns were hand captured at opportunity on the summer range. Trapping efforts were directed to areas where specific migration information was lacking. Most adult does that were captured were fitted with a radio transmitter collar, a colored leather collar with a colored and numbered sheep bell and three 20-25 cm (8-10 inch) colored nylon streamers. A numbered metal ear tag with a 15 cm (6 inch) long colored streamer was attached to the ear (see Salwasser 1972). Bucks and 5 to 6-month old fawns were ear tagged with a streamer attached to the tag. Young fawns were fitted with radio transmitters on expanda- ble collars. (Figure 2)

Telemetry Equipment Twenty-five radio transmitter collars on frequencies between 31.18 MHz and and 31.54 MHz were placed on deer trapped between 1972 and 1974. Power sources were either mercury batteries, solar cells or a combination of solar cells and rechargeable Ni Cad batteries. Transmitter life varied with power source and manufacturer. Beginning in January, 1975, five lithium battery powered transmit- ters on frequencies between 159.315 and 159.405 MHz were placed on deer. Solar cells were no longer used due to transmission problems.
