Kaniukas paprastasis (Elanus caeruleus) iki \u0161iol Lenkijoje buvo laikomas itin retu u\u017eklystan\u010diu pl\u0117\u0161riuoju pauk\u0161\u010diu, ta\u010diau pastaraisiais metais situacija pastebimai kei\u010diasi. Ornitologai fiksuoja vis daugiau patikim\u0173 prane\u0161im\u0173 i\u0161 skirting\u0173 \u0161alies region\u0173, o tai rodo galim\u0105 r\u016b\u0161ies arealo pl\u0117tim\u0105si \u012f \u0161iaur\u0119.<\/p>\n
\u0160is pauk\u0161tis i\u0161siskiria \u0161viesiu, beveik baltu plunksn\u0173 apdaru, kontrastingais tamsiais sparn\u0173 plotais ir ry\u0161kiomis rausvomis akimis. Skryd\u017eio manieros taip pat b\u016bdingos: kaniukas neretai \u201ekabo\u201c ore beveik nejud\u0117damas, primindamas pauk\u0161tvanagini\u0173 \u0161eimos pl\u0117\u0161r\u016bnus, prisitaikiusius med\u017eioti i\u0161 tykojimo.<\/p>\n
Suaug\u0119 individai paprastai u\u017eauga iki ma\u017edaug 30\u201337 centimetr\u0173 ilgio, o sparn\u0173 mostas gali vir\u0161yti 90 centimetr\u0173. Minta daugiausia vabzd\u017eiais, ypa\u010d stambesniais, tokiais kaip \u017eiogai ar vabalai, ta\u010diau gali sumed\u017eioti ir smulkius grau\u017eikus, drie\u017eus ar varliagyvius, jei aplinkoje j\u0173 netr\u016bksta.<\/p>\n
Lenkijoje pirmieji oficialiai patvirtinti steb\u0117jimai prad\u0117jo ry\u0161k\u0117ti tik per pastar\u0105j\u012f de\u0161imtmet\u012f, o nuo to laiko registracij\u0173 skai\u010dius nuosekliai auga. Prane\u0161imai da\u017eniau pasirodo i\u0161 paj\u016brio ir \u0161iaurini\u0173 teritorij\u0173, ta\u010diau pauk\u0161tis fiksuojamas ir kitose vietov\u0117se, tod\u0117l vien atsitiktiniu u\u017eklydimu \u0161\u012f rei\u0161kin\u012f ai\u0161kinti darosi vis sunkiau.<\/p>\n
Specialistai vienu i\u0161 galim\u0173 paai\u0161kinim\u0173 \u012fvardija klimato kait\u0105 ir \u0161veln\u0117jan\u010dias \u017eiemas, kurios sudaro palankesnes s\u0105lygas r\u016b\u0161ims plisti \u012f anks\u010diau per v\u0117sias buveines. Kaniukas paprastasis nat\u016braliai paplit\u0119s Afrikoje, Pir\u0117n\u0173 pusiasalyje ir dalyje Azijos, tod\u0117l \u0161iltesn\u0117s s\u0105lygos Europoje gali palengvinti jo jud\u0117jim\u0105 \u012f \u0161iauresnes platumas.<\/p>\n
Jei fiksuojamas trendas i\u0161liks, neatmetama ir dar svarbesn\u0117 raidos kryptis: laikui b\u0117gant kaniukas gal\u0117t\u0173 ne tik da\u017eniau u\u017eklysti, bet ir prad\u0117ti per\u0117ti regione. Pana\u0161i\u0173 poky\u010di\u0173 Europoje stebima ir kitoms pauk\u0161\u010di\u0173 r\u016b\u0161ims, kai d\u0117l ilgalaiki\u0173 temperat\u016bros bei buveini\u0173 poky\u010di\u0173 kinta migracijos \u012fpro\u010diai ir ple\u010diasi \u012fprastos paplitimo ribos.<\/p>\n","protected":false},"excerpt":{"rendered":"
