Projekta galvenais instruments ir GPS raid\u012bt\u0101ji, kas, atg\u0101dinot nelielu, l\u012bdz 50 gramus smagu “mugursomu”, ir piestiprin\u0101ti septi\u0146iem jaunajiem \u016bpju putniem. \u0160\u012bs ier\u012bces ir apr\u012bkotas ar vis\u0101m nepiecie\u0161amaj\u0101m tehnolo\u0123ij\u0101m \u2013 GPS uztv\u0113r\u0113ju, SIM karti, saules paneli un litija bateriju \u2013 lai prec\u012bzi sekotu putnu gait\u0101m.

Svar\u012bgi atz\u012bm\u0113t, ka pieaugu\u0161ie putni netiek apr\u012bkoti ar raid\u012bt\u0101jiem, lai netrauc\u0113tu vi\u0146u dabisko audzin\u0101\u0161anas procesu.
