Dnipro mieste pasteb\u0117tas ne\u012fprastu elgesiu i\u0161siskiriantis pauk\u0161tis, vadinamas upiniu tilvikiniu. \u0160is pauk\u0161tis da\u017eniausiai laikosi prie g\u0117lo vandens telkini\u0173 ir neretai grob\u012f prie\u0161 su\u0117damas trumpai pamirko vandenyje.<\/p>\n
Ornitologai ai\u0161kina, kad toks elgesys gali tur\u0117ti kelias prie\u017eastis: vanduo padeda nuplauti sm\u0117l\u012f ar dumbl\u0105, o kartais palengvina kietesnio grobio prarijim\u0105. Nors tai atrodo tarsi \u201eplovimas\u201c, da\u017eniausiai tai prakti\u0161kas b\u016bdas grei\u010diau ir saugiau su\u0117sti rast\u0105 maist\u0105.<\/p>\n
Upinis tilvikas da\u017enai i\u0161duoda save judesiais: jis retai stovi ramiai, link\u010dioja galva ir ritmi\u0161kai judina uodeg\u0105. Skrisdamas laikosi \u017eemai vir\u0161 vandens, o ant sparn\u0173 gali matytis \u0161viesesn\u0117 i\u0161ilgin\u0117 juosta.<\/p>\n
\u0160ie pauk\u0161\u010diai renkasi sm\u0117l\u0117tus ar akmenuotus upi\u0173, e\u017eer\u0173, tvenkini\u0173 pakra\u0161\u010dius bei ramesnes \u012flankas. Minta vabzd\u017eiais, vorais, moliuskais ir kirm\u0117l\u0117mis, tod\u0117l da\u017eniausiai j\u0173 galima i\u0161vysti ten, kur seklu ir gausu smulkaus gyv\u016bninio maisto.<\/p>\n
Art\u0117jant prie lizdo, upinis tilvikas gali imituoti su\u017eeidim\u0105: velka \u201enul\u016b\u017eus\u012f\u201c sparn\u0105 ir taip vilioja pl\u0117\u0161r\u016bn\u0105 ar \u017emog\u0173 tolyn nuo jaunikli\u0173. Tai pla\u010diai paplitusi pakran\u010di\u0173 pauk\u0161\u010di\u0173 gynybin\u0117 taktika, padedanti apsaugoti per\u0117jimo viet\u0105.<\/p>\n
Dnipro regione, kaip ir daugelyje Ryt\u0173 Europos vietovi\u0173, \u0161\u012f pauk\u0161t\u012f da\u017eniausiai galima steb\u0117ti nuo pavasario iki rudens. V\u0117liau jis migruoja \u017eiemoti \u012f pietesnius regionus, \u012fskaitant Piet\u0173 Europ\u0105 ir Afrik\u0105.<\/p>\n","protected":false},"excerpt":{"rendered":"
