“…Previous studies have suggested that territorial interactions with conspecifics or competition for limited and patchily distributed resources can influence post‐release movements of translocated animals (Allen, Franzreb & Escano, ; Armstrong, ; Clarke & Schedvin, ; Dunham, ; Coates et al ., ). Although prairie‐chickens are generally not territorial, males do defend small areas on leks (Robel & Ballard, ).…”

“…In contrast, during the early spring resident males remain close to favored leks and only make infrequent large‐scale movements (Hamerstrom Jr & Hamerstrom, ; Patten et al ., ). These same patterns have indeed been observed in translocated grouse as well; translocated females were found to have greater movements than males (Toepfer, ; Musil, Connelly & Reese, ; Coates et al ., ).…”

Translocation projects are often hindered by frequent or long-distance movements made by released animals. Studies identifying how and why animals move after release can inform future translocations and supplement the growing body of literature on translocation biology. We used radiotelemetry to compare movement behavior in 58 resident and 54 translocated endangered greater prairie-chickens (Tympanuchus cupido) that were collected approximately 500 km from the release area. Translocated birds tended to traverse larger areas than resident birds and their movements were elevated immediately following release. We found no evidence of directional orientation in the movements of translocated birds, and thus concluded that prairie-chickens were not homing toward their original capture locations. Rather, post-translocation movements of greater prairie-chickens were more likely associated with exploration. Our results also suggested that 54% of translocated females and 19% of translocated males may permanently emigrate from a release site. We recommend that greater prairie-chicken conservationists consider summer releases and larger release cohorts to account for the individuals that emigrate from the establishment site. Based on our findings, we further suggest that a greater number of future translocation projects consider the utility of evaluating post-release movements as a means of informing translocation decisions. bs_bs_banner Animal Conservation.

“…As predicted, T1s moved significantly more per day compared to all others. The pattern of newly translocated individuals moving large distances has been observed in a variety of taxa including Agassiz's desert tortoise ( Gopherus agassizii ; Nussear et al ), Columbian sharp‐tailed grouse ( Tympanuchus phasianellus columbianus ; Coates et al ), and swift foxes ( Vulpes velox ; Moehrenschlager and Macdonald ). For sage‐grouse in our study, these expansive movements drastically decreased after the first year, with T2s exhibiting smaller annual movement patterns than residents after their first year.…”

Effects of post‐release movements on survival of translocated sage‐grouse

et al. 2019

Translocation is a vital tool in conservation and recovery programs, and knowledge of factors that determine demographic rates of translocated organisms is important for assessing the efficacy of translocations. Greater sage‐grouse (Centrocercus urophasianus) have been the subject of recent translocation efforts because of their declining range and their usefulness as an umbrella species for conservation. Using a long‐term data set on sage‐grouse in central Washington, USA, we compared movement and demographic rates of translocated and resident birds. Because newly translocated birds experience physiological stress during translocation and are released in unfamiliar habitat, we hypothesized their demographic rates would differ from residents. We analyzed 18 years of radio‐tracking data acquired from resident, newly translocated (<1 yr post‐translocation; T1), and previously translocated (>1 yr post‐translocation; T2) sage‐grouse between 1989 and 2017 to estimate movement rates, survival, and productivity. Newly translocated sage‐grouse exhibited farther daily movements (0.58 km/day) and smaller 95% home ranges (89 km2) than residents and previously translocated birds. Daily movements and sex influenced survival, but survival did not differ according to residency status. Furthermore, birds that survived to a second year after translocation exhibited shorter daily movements compared to their first year (trueβˆ = −0.727 ± 0.157 [SE]), which corresponded with increased survival the second year (T1 = 0.526, T2 = 0.610). This decrease in movements and increase in survival the second year was not apparent in the control group of resident birds, indicating a possible behavioral link to survival of newly translocated sage‐grouse. Most productivity metrics were similar for translocated and resident birds, except for nest propensity (i.e., nest initiation rate), which was lower for newly translocated birds (35%) compared to residents and previously translocated birds. Our results reveal that translocated sage‐grouse exhibit temporary differences in some demographic parameters in their first year, which later align with those of resident birds in subsequent years. Similarities in adult and nest survival according to residency status further suggest that translocation may prove to be a viable tool for restoring and conserving this species. Continued declines in sage‐grouse populations in Washington, however, indicate that habitat conversion and fragmentation may be reducing demographic rates of residents and translocated birds, which warrants further study. © 2019 The Wildlife Society.

“…In prairie grouse, a species that has been difficult to restore, individuals move substantial distances away from the release site (Coates, Stiver & Delehanty, 2006). Translocated individuals have also been documented returning to the original site of capture (Carrie et al, 1996;Clarke & Schedvin, 1997;Fancy, 1997).…”

The ultimate goal of most translocation efforts is to create a self-sustaining wild population of a species deliberately moved from one part of their range to another. As follow-up of a translocation attempt is often difficult, causes for failure are relatively unknown. Dispersal away from the release site is one potential source of failure because it decreases the likelihood of the released population establishing itself post-translocation. In this study, we used chukar Alectoris chukar as a surrogate for translocated game birds in order to conduct a large-scale experimental study. We observed that these desert-adapted birds demonstrate a strong fidelity for specific water sources. We also report the propensity for the translocated individuals to either disperse and return to their original water source site or remain at the release site. During two field seasons, we observed opposing behaviors such that the proportion of individuals returning to the capture site, versus those remaining at the release site, shifted between years. We analyzed this change between the years as well as within the years to assess the potential underlying causes such as translocated distance, differences in rainfall between seasons and water source type. We concluded that homing behavior was strong in this non-migratory bird species and that strength of this homing behavior varied, potentially due to conditions surrounding the limiting resource, water availability. The large-scale, original data presented here may help to explain why some releases result in a successfully established population while other releases result in widely dispersed individuals.
