Hybrid Aythya ferina x Aythya nyroca?
« Gepost op: januari 05, 2020, 15:44:04 pm »

Hello all,

I would welcome some assistance with the identification of a dark female-type Aythya duck that I saw this morning in Ijburg, Amsterdam this morning. The record, including photos, can be found here:

Dank je wel,

I wonder of it is not a pure Ferruginous female Avery because head (triangular) and bill (long & sloping) fit this species perfectly. But you will need some better pictures for establishing i.e. the bill pattern.

Frank
