Subspecies: mollissima
Likely 2cy male in eclipse plumage. This by the overall dark plumage and the well-developed sail-shaped scapulars. However, males in eclipse plumage are in general very variable, and probably not always possible to age based on photos like these. Only saw the bird sitting on the water.

The subspecies is the one expected in Denmark, but is also supported by the delicate detail of the bill-feathering overlapping the nostril markedly.

The bird was alone.

Guessing adult female with well-developed white wing bands and light bill with pale tip. Was with birds in 3186.

Subspecies: mollissima
Assuming 2cy male to the left with the black belly but too much on the head on the wing to just be an adult still molting out of eclipse plumage. The bird on the right looks like a 1cy male. Age indicated by the white appearing on the scapulars. Were with female in 3185.

2019-11-04   Dragør, Amager, Denmark

Subspecies: mollissima
Adult male in transition to breeding plumage, still lacking the green nape and the pure salmon colored chest. Resting inside the harbor next to the Mallards (that are being fed) is a bit unusual, and the way the breast seems to protrude extraordinarily, could indicate that something is wrong. A too full stomach might be a reason as well, guessing it preferred this sheltered spot on a day with a good wind swiping the sea outside.

Adult. Male. By the all-black bodysides I'm assuming an adult male slowly transforming from eclipse to plumage of splendor. Normally not that approachable but on this quiet gray day, the friendly company of me and a Mallard apparently was acceptable.
