Iberian lynx ( Lynx pardinus ) reintroductions are part of this species’ conservation program to ensure its re-establishment and survival in areas of historical presence. Release protocols include hard-release, directly in the field, and soft-release, allowing reintroduced animals to acclimatize to the new environment site, which may lead to higher survival and reproductive rates. During soft-release reintroductions in Extremadura (Spain), we recorded individual and social behaviors of four released Iberian lynxes in a 1.5-ha enclosure, divided into three longitudinal strips to simplify behavioral data collection: zone 1, or releasing area, containing an additional feeding point; zone 2, or central zone, with rocks and natural rabbit refuges; and zone 3, or the farthest zone from the releasing area, of abundant arboreal vegetation. Our results showed that “pacing”, “lying” and “patrolling” were the most common behaviors observed in the four lynxes. Social interactions such as “approach”, and “lordosis” were the most common and indicated significant differences between individuals. Concerning sexes, males exhibited the behavior “showing indifference,” unlike females that never presented it. Data collected revealed that the lynx had a preference for zone 3 of the enclosure. Pre-release behavior monitoring is critical I n Iberian lynx soft-release reintroductions in order to ensure their acclimatization to the new site, identify their survival skills and allow their establishment in the reintroduction areas.
