Beskrivelse: This bird was discovered the previous day in the evening hours and was the next day present until around 11 AM and then flew away in a SW direction.
Beskrivelse: Again, a drake... Unringed and able to fly, he was seen at far range (380m). Shy, moving, eating and flying a lot... Is it normal for "plastic"?
Beskrivelse: This first winter male have an strange color by his rufous wings and undertail coverts.
The main problem on this bird is the following:
When can we be sure that this kind of plumage is a less knowed variation or a far fact of Black-throated x Naumann hybrid?
