  • Harlem Deer Caught in City-State Tussle Has Died, New York Times, Dec 16, 2016A white-tailed deer that went from being a minor celebrity in Harlem to a cause célèbre after its capture, died in captivity on Friday, moments before it was to be driven upstate and released. The preliminary causes of death, according to a New York City parks spokesman, were stress and the day and a half that the deer spent at a city animal shelter in East Harlem.
  • Left truncation criteria for survival analysis of white-tailed deer, Wildlife (WilsonOnline), Aug 2016Survival estimates are commonly obtained by physically capturing wildlife and marking or affixing a transmitter to a representative sample of the population. Bias induced by capture stress can occur for white-tailed deer (Odocoileus virginianus) if capture influences the probability of mortality. To mitigate this bias, researchers often left truncate data for a threshold number of days (14–28 days for deer) after capture. Potential costs of left truncation include reduced sample size and reduced inference. Costs associated with capture and monitoring of deer are substantial, and defining a truncation period is usually arbitrary or ad hoc. Hence, researchers need to evaluate objectively the effects of left truncation. We analyzed time-to-event data from 1,001 radio-collared white-tailed deer from northern forests and eastern farmlands of Wisconsin, USA in 2011–2014 to evaluate justification for using a 2-week truncation period by comparing the probability of mortality for deer <2 weeks post-capture and deer ≥2 weeks post-capture. We found little support for a difference in mortality between the groups. Results accounting for time of year, study area, and age suggested a 0.69 probability that deer ≥2 weeks post- capture had a lower mortality rate than deer <2 weeks post-capture. Using a reference group of 6–10 -month-old deer in the eastern farmlands in 2011, cumulative capture season mortality was 0.102 (50% CI = 0.075–0.125; SE = 0.037) for deer <2 weeks post-capture and 0.114 (50% CI = 0.087–0.138; SE = 0.037) for deer ≥2 weeks post-capture.

  • High Mortality —
    Studies have shown that approximately 4% of the deer die in transport, as many as 25% of translocated deer die within the first two months of trapping and translocation, and more than 85% of deer may not survive longer than one year.

  • Influence of social organization on dispersal and survival of translocated female white-tailed deer, Wildlife Society Bulletin, 1997Postparturient females released without their fawns dispersed farther than females released while pregnant or barren (P ≤ 0.04). Survival did not differ between translocated groups (P = 0.47), but translocated deer had lower survival than resident deer at the release site (P = 0.06). Home-range size of 5 translocated deer after 1 year postrelease did not differ from 8 resident deer (P= 0.88).
