La seva detectabilitat fora del per\u00edode de cria \u00e9s molt baixa, i la seva activitat de cants es concentra principalment a la primera hora abans de l&#8217;albada.<\/p>\n\n\n\n<p>En aquest sentit, el seguiment remot mitjan\u00e7ant radiotelemetria es mostra com una eina efectiva.<\/p>\n\n\n\n<p>El m\u00e8tode que emprem per al seguiment dels individus translocats i de control (els que romanen a la poblaci\u00f3 &#8216;font&#8217;) consisteix en el marcatge dels ocells amb radioemissors VHF codificats Coded (NTQB2-4-2 Coded nanotag de 0.9 g; Lotek Wireless Inc., Canad\u00e0), i en la instalaci\u00f3 d&#8217;estacions fixes autom\u00e0tiques de recepci\u00f3 del senyal.<\/p>\n\n\n\n<p>Aquests dispositius, a difer\u00e8ncia dels cl\u00e0ssics VHF o Beeper, emeten tots a la mateixa freq\u00fc\u00e8ncia, per\u00f2 amb diferent pols, i tenen una durabilitat molt major que els emissors cl\u00e0ssics, la qual cosa els fa especialment adequats per als objectius que es marquen en el present projecte.<\/p>\n\n\n\n<p>A cada \u00e0rea de translocaci\u00f3 i en les zones d&#8217;origen, s&#8217;ha instal\u00b7lat una estaci\u00f3 fixa de radioseguiment autom\u00e0tic. Aquesta estaci\u00f3 s&#8217;instal\u00b7la en un punt central i elevat de l&#8217;\u00e0rea per facilitar la recepci\u00f3 del senyal dels animals marcats <em>Coded<\/em>.<\/p>\n\n\n\n<p>Cada estaci\u00f3 est\u00e0 composta d&#8217;un receptor, quatre antenes <em>Yaggi <\/em>de 3 elements (programades amb una freq\u00fc\u00e8ncia central de 150.100 MHz), quatre cables coaxials i una font d&#8217;alimentaci\u00f3.<\/p>\n\n\n\n<p>Els receptors \u00f2ptims per a aquest tipus de seguiment s\u00f3n els SRX1200-D de Lotek (Lotek Wireless Inc., Canad\u00e0), que descodifiquen directament els ID dels emissors codificats, generant una base de dades de les deteccions.
