Abstract:
Abstract 10.1002/(SICI)1098-2361(1999)18:3<189::AID-ZOO3>3.3.CO;2-V Three male maned wolves were successfully introduced to their mates and 7- to 12-week-old pups at the Houston Zoological Gardens and Fossil Rim Wildlife Center in 1994 and 1995. The introductions took 3–7 weeks and had three stages: 1) allowing the male to see the female and pups through a chain-link panel or a full chain-link fence, 2) introducing the male and female without the pups present, and 3) introducing the male to the pups. For 7 days before Stage 2 and 7 days during Stage 3, the adults were observed for 150 hr. The amount of time they spent active and the amount of time they spent near the pups were recorded, as well as all behaviors they directed to the pups. After the males were introduced, the females’ activity decreased, and the males’ activity increased. The females spent less time near the pups after the introduction. The introduction did not affect the females’ rates of affiliative or aggressive behaviors to the pups, and there was no difference between males’ and females’ rates of affiliative or aggressive behaviors. This introduction procedure offers an alternative to leaving the male with the pups from the time they are born. The adults’ behavioral changes after the introduction show the benefits that occur when captive male maned wolves are allowed to help rear their pups.
