Comments : |
Adult Whooper Swan with an atypical bill pattern (so-called 'Dark neb'), almost Bewick's-like in appearance when viewed from above, but then normal when viewed side on. Part of a flock of 45 (including 14 1st-winters) in the fields at Newcastle.
NOTE: "The bill patterns of Bewick's & Whooper swans are split into three categories: (1) 'Yellow neb' - all yellow at the top of the bill, (2) 'Dark neb' - totally black strip from top to bottom & (3) 'Penny face' - a black strip with a small yellow circular patch in the middle of the bill. 'Penny faces' & 'Yellow nebs' are common in Whooper Swan but 'Dark nebs' are very rare, <1% (!) of birds in flocks are 'Dark neb'." Many thanks to Kane Brides (Wildfowl & Wetlands Trust) for this information.
