Denning and maternal behavior of caracals (Caracal caracal)

Abstract

Knowledge of behaviors surrounding reproduction in wild species is essential to the development of effective management and conservation strategies. Many carnivores use dens to increase the safety and survival of their neonatal young while females shift to central-place foraging to meet the energetic demands of raising young. Caracals (Caracal caracal), a medium-size wild cat, have a widespread geographic distribution but limited information from minimal observations exists on the behaviors associated with denning and caring for young. We report observations of dens used by four caracals in the surrounds of Cape Town, South Africa, including the duration of den use, maternal home ranges, and movements away from dens. Three of four females established denning in September and one in December, suggesting a birth pulse during the Southern Hemisphere spring and summer. Of seven den sites we documented, six were in dense shrubland fynbos vegetation and one among boulders; all of which had thick overhead cover. Females and neonatal young used 1–3 primary dens for approximately six weeks, followed by the use of short-term auxiliary dens. Female maternal home ranges were approximately 31% the size of their home ranges estimated using all their data. Trips away from the dens averaged 12 h while the average maximum distances across all trips away from dens for each female was 1135 m (range = 801–1327 m). Our observations inform our understanding of the timing and physical characteristics of caracal dens and help fill research gaps on the natural history of caracal denning behavior.
