128885 Ring-necked Duck Aythya collaris. Each autumn, a scattering of genuinely wild ducks from North America arrive here, blown in by Atlantic gales. Typically they associate with their most similar European counterparts. Ring-necked Duck Aythya collaris (L 38-45cm) is similar to a Tufted Duck but with a peaked crown and tri-coloured bill. Mainly black and white male has a vertical white line on flanks and brownish female has a white ‘spectacle’ around the eye.
