ACTIVITY & PROXIMITY PATTERNS OF JUVENILE HOWLING MONKEYS

幼年的吼猴在大部分时间里都是单态的， 青少年时期没有性别差异是明显的，直到他们 性成熟。 我们希望确定是否有 行为上的差异让我们能够非侵入性地确定 性 5岁以下幼吼猴的行为和接近 对Hacienda La Pacifica上不同社会群体的年龄进行了比较， 和性别差异。 病灶动物观察（695.9小时）显示 不同年龄的人在活动模式上没有显著差异， 或性别，但在接近母亲方面存在差异。 接近成年女性是不同的年龄，最年轻的 在成年雌性附近呆的时间最少的动物。 那里 在接近成年男性的年龄没有差异，但少年 雄性花在成年雄性附近的时间明显多于雌性。 在与其他人的接近度方面，年龄或性别没有差异。 青少年，或在游戏中的任何差异。 吼猴幼猴 似乎在行为模式上几乎是单态的，

Juvenile howling monkeys are monomorphic during most of their juvenile period as no sexual differences are apparent until they become sexually mature. We hoped to determine if there were behavioral differences which would allow us to noninvasively determine sex. Behavior and proximity of juvenile howling monkeys from 5 different social groups on Hacienda La Pacifica were compared for age and sex differences. Focal animal observations (695.9 hours) revealed that there were no significant differences in activity pattern by age or by sex, but that there were differences in proximity to mother. Proximity to adult females were different by age, with youngest animals spending the least amount of time near adult females. There were no differences in proximity to adult males by age, but juvenile males spent significantly more time than females near adult males. There were no differences by age or sex in proximity to other juveniles, or any differences in play. Howling monkey juveniles appear to be almost as monomorphic in behavior patterns as they are
