Alcedo atthis (oddiy qirg‘iyqush) suv havzalari bilan chambarchas bog‘liq bo‘lgan, o‘ljasini asosan vizual yo‘l bilan aniqlovchi ixtisoslashgan qushlardan biridir. Ushbu maqolada A. atthis ning suv ostida ko‘rish, o‘lja lokalizatsiyasi va yo‘nalishni aniqlash jarayonlarining morfo-fiziologik asoslari tahlil qilinadi. Tadqiqotning asosiy e’tibori ko‘zning optik moslashuvi, to‘r parda ixtisoslashuvi, binokulyar koordinatsiya, bosh-harakat barqarorligi, vestibulyar va vizual oqim mexanizmlariga qaratildi. Tahlillar shuni ko‘rsatadiki, A. atthis ning suv ostida samarali ovlanishi ko‘zning tez akkomodatsiyasi, yuqori fazoviy aniqlikni ta’minlovchi retinal tuzilmalar, niktitatsion parda orqali ko‘zni himoyalash, boshning stabilizatsiyasi va sensor-motor integratsiya bilan bog‘liq murakkab moslanishlar natijasidir. Ushbu moslanishlar suv–havo chegarasida yuzaga keladigan refraksion buzilishlarni qisman kompensatsiya qilib, suv ostida aniq vizual yo‘nalish va zarba aniqligini ta’minlaydi.
