In the fishing ports local fishermen leave the nets out to dry. I guess the nets contain rotting seafood and in early May some kind of fly lay their eggs in the stinking netting and when the insects emerge they are food for any birds in the area.
Chestnut-cheeked Starlings are common summer visitors and flocks of them were feasting on the flies………..
Not a vintage Golden Week for birds. Despite fine weather and lots of time off and traveelling around SW Hokkaido I didn’t see anything particularly rare or unusual. Yakumo still had plenty of wildfowl on the 4th/6th including Garganey, Falcated Duck and White-fronted Geese and both species of Scoter were offshore at Oshamanbe. Other summer visitors to arrrive included Oriental Reed Warbler, Brown-headed Thrush and Oriental Cuckoo. On passage there were lots of Dusky Thrush and a nice male Rustic Bunting (at Yakumo) but not much else.
The above Intermediate Egret was at Yakumo. All 3 species of commoner egret weer evident across the region at the weekend: this is the scarcest of the 3.
There were lots of duck species around at Yakumo today. The avove Falcated Duck and a male Garganey were the most interesting and there were also Gadwall, Shoveler and another dozen or so species as well as Mandarin Duck and Smew at Onuma.
