Description
Vaginal-implant transmitters (VITs) are radio-transmitters that are inserted into, and designed to be expelled from, the birth canal of an ungulate during parturition. These devices have the potential to be excellent field tools for biologists to use in locating and capturing neonatal ungulates. Fawns of deer (Odocoileus) are difficult to locate due to their cryptic coloration and hiding behavior (White et al., 1972). With VITs, timing and location of births can be determined accurately (Carstensen et al., 2003; Bishop et al., 2007; Haskell et al., 2007). Previously, researchers opportunistically captured fawns of all ages (Downing and McGinnes, 1969; White et al., 1972; Hugel et al., 1985; Ballard et al., 1999). An advantage of VITs is that fawns can be captured from marked females, giving researchers the ability to link characteristics of females (e.g., mass, fat, age) to fate of fawns. Opportunistically capturing fawns rarely allows for this type of comparison. Overall, use of VITs does not influence survival of neonates and may reduce bias associated with opportunistically capturing fawns without locating birthing sites (Carstensen-Powell et al., 2005; Bishop et al., 2007; Haskell et al., 2007; Swanson et al., 2008). With VITs, biologists can randomly capture fawns spatially and temporally allowing data to be gathered from time of birth (Bishop et al., 2007). Our objective was to determine efficacy of VITs for capturing fawns of mule deer and to establish whether successful use of VITs differed among years, among implanting times, or between populations. We compared rates of successful use of VITs that had two different widths of wings.
