7th June 2015 @ Sagami Gulf (off the coast to Jyoga-shima) *possible juvenile It seems that moulting of adult Japanese Murrrelets begin from the end of July. So it is hardly posible that this individual is an adult winter plumage. As the colour of bill is not pale blue-grey but blackish, this individual is possible juvenile which was hatched in this early spring(April).
