The collar on Mushara has managed to send in a little more data this week, and we have a grand total of three points, spread over three days (one each day). Early afternoon on Friday they were close to the Boscia waterhole. Just after Midnight on Saturday they were close to the holding pens, and on Sunday morning they were apparently heading back towards Boscia.
I have no way of telling what part of the collar is failing, i.e. if it is failing to download GPS points, or failing to upload them. Once we get the collar back however, it will be possible to access to complete set of GPS points downloaded for the entire time the collar has been operating.
