The timing and synchrony of births of roe deerCapreolus capreolus Linnaeus, 1758 population were examined for 7 consecutive years in northern Italy. From 1997 to 2003, 136 fawns, 65 females and 71 males, from 117 litters were captured. The average date of fawning (30th of May) was constant among years and between sexes. The onset of parturition was 19th of May while the total length of the parturition season was 25 days (from 19th of May to 13th of June). Births were highly synchronous, with 80% of births occurring in 17 days. Synchrony of birth did not exhibit any significant interannual or intersexual variation. The stability of the birth pattern was confirmed by the parturition date of 13 radiocollared females who all gave birth within 4 days in consecutive fawning seasons. In agreement with previous findings, our data support the hypothesis that the roe deer is constrained at both ends of the fawning season by the short time between the fawning season and rut and by the need to match optimal climate conditions and forage quality to face late gestation and lactation. All these factors result in a relatively stable and synchronous birth season.
