This cow (Bos taurus) is modeling a custom-made GPS collar that will be used to collect data on grazing behavior. Collars have to be sturdy and robust, so that these mischievous girls will not shake them off or rub them off while they are grazing extensive rangelands. The GPS devices in these collars store the data collected and do not transmit data to an antennae, therefore if they are lost they are probably not going to be found again!
