Aythya Hybrid

Possible Ring-necked/Tufted Duck Hybrid, Fen Drayton Lakes RSPB, 13th December 2011 © Richard Thomas
'An interesting drake Aythya hybrid this am in the southwest corner of Ferry
Lagoon. Although not as clear-cut as some Ring-necked x Tuftie examples on the web (bill
pattern not very striking, hardly any white along flanks edges), my money would
be on it being this hybrid combination given its head shape and grey flanks.' RT
