I was lucky to have been introduced to a lady, Mrs M, who has been observing and counting sea ducks along the Pacific coast in Chiba and one day she took me to show me round her area.
One of the main targets (for me) was the Black Scoter (Kurobamoクロガモ), which are very closely related to the Common Scoter seen in the sea around the UK.
The Black Scoter were floating in pairs or groups of 5-10. Some males tried hard to impress the ladies and the others were just chilling out.
Another sea duck I'd wanted to see was the Harlequin Duck (Shinorigamoシノリガモ）and I was told that they are considered as a hardy duck as they are easily found where waves break like this -
Quite a few Red-throated Divers (Abiアビ) were seen as well.
Mrs M was very knowledgeable and I learnt a lot about sea ducks and other wintering sea birds. I would like to be like her eventually!
