Hello thank you for your comment, i researched it if i maked mistake but ringed-necked Pheasant have on ebird and our czechia scientific portal biolib.cz which is edited by scientist and reasearchers from czechia, and it says Phasianus colchicus, maybe you meant Phasianus colchicus torquatus which is a Ring-necked Pheasant but side specie in our language Bažant obecný jihočínský. i used the Linnaeus one you said is Gmelin. But is technically both correct but you maked it next level and added a side specie. Thank you i will edit it.
@nature_of_czech_republic1213, actually, a recent study shows that Phasianus colchicus is paraphyletic as black-breasted, black-necked, and ring-necked pheasants are all now three separate species rather than the same species, the Black-Breasted Pheasant (Phasianus elegans) has six recognized subspecies within two subspecies groups: the Phasianus elegans elegans group that contains the Rothschild's Black-Breasted Pheasant (Phasianus elegans rothschildi), the Stone's Black-Breasted Pheasant (Phasianus elegans elegans), and the Qinghai Black-Breasted Pheasant (Phasianus elegans vlangallii) and the Phasianus elegans principalis group that contains the White-Winged Black-Breasted Pheasant (Phasianus elegans chrysomelas), the Bianchi's Black-Breasted Pheasant (Phasianus elegans bianchii), and the Prince of Wales's Black-Breasted Pheasant (Phasianus elegans principalis), the Black-Necked Pheasant (Phasianus colchicus) has twelve recognized subspecies within three subspecies groups: the Phasianus colchicus decollatus group that contains the Kweichow Black-Necked Pheasant (Phasianus colchicus decollatus) and the Sungpan Black-Necked Pheasant (Phasianus colchicus suehschanensis), the Phasianus colchicus tarimensis group that contains the Satchu Black-Necked Pheasant (Phasianus colchicus satscheuensis), the Gangdisi Shan Black-Necked Pheasant (Phasianus colchicus gangdisishanensis), the Tarim Black-Necked Pheasant (Phasianus colchicus tarimensis), and the Yarkland Black-Necked Pheasant (Phasianus colchicus shawii), and the Phasianus colchicus colchicus group that contains the Amu-Darya Black-Necked Pheasant (Phasianus colchicus zarudnyi), the Persian Black-Necked Pheasant (Phasianus colchicus persicus), the Talisch Black-Necked Pheasant (Phasianus colchicus talischensis), the Caucasian Black-Necked Pheasant (Phasianus colchicus colchicus), the Turkish Black-Necked Pheasant (Phasianus colchicus turcicus), and the Caspian Black-Necked Pheasant (Phasianus colchicus septentrionalis), and the Ring-Necked Pheasant (Phasianus torquatus) has eighteen recognized subspecies within five subspecies groups: the Phasianus torquatus sohokhotensis group that contains the Strauch's Ring-Necked Pheasant (Phasianus torquatus strauchi), the Sohokhoto Ring-Necked Pheasant (Phasianus torquatus sohokhotensis), and the Alashan Ring-Necked Pheasant (Phasianus torquatus alaschanicus), the Phasianus torquatus torquatus group that contains the Tonkinese Ring-Necked Pheasant (Phasianus torquatus takatsukasae), the Shandong Ring-Necked Pheasant (Phasianus torquatus shandongensis), the Sichuan Ring-Necked Pheasant (Phasianus torquatus torquatus), the Hainan Ring-Necked Pheasant (Phasianus torquatus hainanus), and the Formosan Ring-Necked Pheasant (Phasianus torquatus formosanus), the Phasianus torquatus karpowi group that contains the Shansi Ring-Necked Pheasant (Phasianus torquatus kiangsuensis), the Mandarin Ring-Necked Pheasant (Phasianus torquatus liaoningensis), the Manchurian Ring-Necked Pheasant (Phasianus torquatus pallasi), and the Korean Ring-Necked Pheasant (Phasianus torquatus karpowi), the Phasianus torquatus hagenbecki group that contains the Kobdo Ring-Necked Pheasant (Phasianus torquatus hagenbecki) and the Ruo Shui Ring-Necked Pheasant (Phasianus torquatus edzinensis), and the Phasianus torquatus mongolicus group that contains the Mongolian Ring-Necked Pheasant (Phasianus torquatus mongolicus), the Zerafshan Ring-Necked Pheasant (Phasianus torquatus zerafschanicus), the Syr-Darya Ring-Necked Pheasant (Phasianus torquatus turcestanicus), and the Aral Ring-Necked Pheasant (Phasianus torquatus bergii), it is now known that the ring-necked pheasant is more closely related to the Green Pheasant (Phasianus versicolor) than it is to the other two extant species, which explains the paraphyly of Phasianus colchicus.
You got the scientific name of the ring-necked pheasant completely wrong, its correct scientific name is actually Phasianus torquatus.

I never study it that closely thank you for new informations and have a nice Day. (i will repair it)
