I was success to see many sea birds in this cruising.
In intermediate coast area, c.a. 50 divers (mainly Pacific) which almost changed summer plumage were seen. They were so beautiful.
They seemed to have high wariness and not good at launch from water surface.
I recognized Red-necked Loon and Black-throated Diver.
And a summer plumage Long-billed Murrelet flew away from my boat.
And I headed further out of sea and saw other exiting birds. I'll mention about it later.
