Abstract
Abstract Marking-induced abandonment has been suggested as the most common cause of marking-induced mortality of free-ranging, newborn ungulates in North America. However, there has been no direct study of marking-induced abandonment in free-ranging ungulates, and its relevance to neonate survival is inconclusive. We describe our capture, marking, and monitoring of white-tailed deer (Odocoileus virginianus) neonates born to radiocollared dams in north-central Minnesota over 5 springs (1997, 1999–2002), as it relates to marking-induced or natural abandonment. We assumed that all neonates dying within 4 days post-marking were possible occurrences of abandonment. We captured 89 neonates; 6 (7%) died within 4 days (4 to predation, 2 to unknown causes). We found no conclusive evidence of marking-induced abandonment. Handling had no impact on neonate survival, even though nearly 40% of neonates were handled >15 minutes. Time of marking (post-parturition) was similar among survivors and nonsurvivors; 48% of surv...
