A global positioning system (GPS) collar recorded the locations of an adult female Japanese macaque over a 9-day period in a habitat with mixed suburban and rural land-uses in Chiba Prefecture, Japan. The GPS device acquired positions even in forested areas. The GPS data located the female mostly in forested areas, although the female had ranged through a habitat with inter-mingled fields, orchards, quarries, and residential areas. However, the GPS position acquisition rate was low compared to studies carried out on North American mammals. The GPS fixed a position in 20% of positioning attempts. When the collared female was tracked by radio-telemetry, almost all failures of the GPS to fix a position occurred in forest.
一个全球定位系统（GPS）项圈记录了一只成年雌性日本猕猴在日本千叶县一个郊区和农村土地利用混合的栖息地中9天内的位置。即使在森林地区，GPS设备也能获取位置。GPS数据显示，这只雌性猕猴大多位于森林地区，尽管它也曾在一个有农田、果园、采石场和居民区交错的栖息地活动。然而，与对北美哺乳动物进行的研究相比，GPS位置获取率较低。在20%的定位尝试中，GPS能够确定位置。当通过无线电遥测追踪佩戴项圈的雌性猕猴时，GPS定位失败的情况几乎都发生在森林中。
