Only 39 calling males were counted in comparison with 60 in 1998, although their distribution remains roughly the same, with the highestdensiry in areas along the Ljubljanica river. The species is completelyabsent from dense woodland, highly populated areas with well-developed infrastructure, intensive agricultural areas and areas closely surrounded by hills5. maja 1999 smo opravili popis velikega skovika na Ljubljanskem barju (163 km2). S predvajanjem samčevega petja smo zabeležili 40 velikih skovikov. Največ jih je pelo v Črni vasi, Lipah, Blatni Brezovici, Bevkah in na Robidnicah, kar daje podobno sliko razširjenosti kot rezultati popisa iz leta 1998 (Senegačnik 1998). Na nekaterih predelih velikih skovikov nismo registrirali (Brezovica, Vrhnika, Škofljica, Želimlje, Iška vas, Podpeč, Jezero), kar pripisujemo neugodnim življenjskim razmeram: ceste, gosta poseljenost, hrup, pomanjkanje gnezdišč, zaprtost terena. Zabeležili smo tudi oglašanje lesne sove, dveh malih uharic in čukaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo za opazovanje in proučevanje ptic Slovenije
