キンクロハジロ A Ringed Tufted Duck

It was the first time for me to find a ringed Tufted Duck at Syakuii Park in Tokyo. 

金属リングを装着したキンクロハジロを初めて見つけましたが、番号を読める機会は訪れず、証拠写真も撮影できませんでした。残念！

I tried to take photos to read the number even just a part, but I couldn't. It is not easier to check the ring number of diving ducks than dabbling ducks, because diving ducks generally rest on the water and there are few opportunities to check and photograph their legs closely.

I will get another chance someday!
