Birds along the Yamaguchi Coast

This past Spring while walking the Chugoku 33 Kannon Pilgrimage I took a walk along the Japan Sea coast of Yamaguchi,  It's a particularly fine stretch of coast with azure seas, outcroppings and cliffs, small islands and a lot of small fishing villages. Here are some of the birds I saw. The first is a heron. Sagi in Japanese, maybe its a Grey heron, maybe a Great Blue......

Lots of cormorants. I am guessing that they are Temmink's Cormorants, the most common kind, known as Umi-u in Japanese, though there are some other species which visit during migration. The difference among the onbes in the photo may be due to age and gender.

Lots of Kites, Black-eared Kite being the common species here. Known as Tombi in Japanese.

More cormorants.

This is, I believe, a Blue Rock Thrush, but I have no idea what it is called in Japanese.
