Jeden incident v roce 2017 se t\u00fdkal nalezen\u00e9 kobry omotan\u00e9 kolem okna vlaku, kter\u00e1 sy\u010dela na cestuj\u00edc\u00ed.

V\u011bdci z Leibniz Institute for Biodiversity Change Analysis a Victor Valley College studovali 47 z\u00e1chrann\u00fdch m\u00edst kobry kr\u00e1lovsk\u00e9 v Goa v letech 2002 a\u017e 2024. Zjistili, \u017ee p\u011bt had\u016f bylo nalezeno v oblastech zcela nevhodn\u00fdch pro jejich p\u0159e\u017eit\u00ed, v\u0161ichni v t\u011bsn\u00e9 bl\u00edzkosti vlakov\u00fdch trat\u00ed nebo stanic. <\/p>\n
Kobra kr\u00e1lovsk\u00e1 z\u00e1padn\u00ed Ghats, druh ofici\u00e1ln\u011b uznan\u00fd a\u017e v roce 2024, preferuje chladn\u00e9, vlhk\u00e9 horsk\u00e9 lesy. Zachr\u00e1n\u011bn\u00ed hadi v\u0161ak byli nalezeni v such\u00fdch, n\u00edzko polo\u017een\u00fdch oblastech, daleko od ide\u00e1ln\u00edch podm\u00ednek pro chov.

Motivace t\u011bchto cest z\u016fst\u00e1v\u00e1 nejasn\u00e1. V\u011bdci spekuluj\u00ed, \u017ee hadi mohou lovit ko\u0159ist (jako jsou hlodavci nebo jin\u00ed hadi) nebo hledat \u00fakryt, ne\u017e se usad\u00ed, aby str\u00e1vili potravu.

Navzdory jejich siln\u00e9mu jedu a rychlosti je nepravd\u011bpodobn\u00e9, \u017ee by kobry kr\u00e1lovsk\u00e9 napadly lidi, pokud by nebyly zahn\u00e1ny do kouta nebo vyprovokov\u00e1ny. Jak vysv\u011btluje herpetolog Hinrich Kaiser: \u201eNejste pro n\u011b potravou, tak\u017ee v\u00e1m rad\u011bji uhnou z cesty.\u201c P\u0159\u00edtomnost t\u011bchto had\u016f v obydlen\u00fdch oblastech v\u0161ak p\u0159edstavuje potenci\u00e1ln\u00ed riziko, zvl\u00e1\u0161t\u011b pokud se c\u00edt\u00ed ohro\u017eeni. <\/p>\n
