俄羅斯一個研究團隊在一隻草原雕身上裝上GPS追蹤器,每天記錄牠的位置12次,若位置沒有網絡即會累積到下次有網絡時補發。結果草原雕在沒有網絡的哈薩克西部停留了整個夏季後到達伊朗,大量訊息要從伊朗送回,花費了比預算昂貴的漫遊費用。團隊決定以眾籌來支付這隻草原雕及另外12隻雀鳥的漫遊費用。
A group of scientists in Russia set a GPS tracker on a steppe eagle, and track its location 12 times a day, if it goes outside mobile coverage area, the data will be stored and send back to Russia when it gets coverage again. This eagle spent most of its summer out of coverage in western Kazakhstan then entered Iran; all the data had to send from Iran back to Russia with expensive roaming text messages. The roaming fee was a lot more than they expected, and they decided to crowdfund to support the roaming fee for this steppe eagle and 12 other birds they are tracking.
