I went birdwatching on the side while on a work trip to cover the Yonaguni Town Council election. ^^
I confirmed multiple migrating Chinese Sparrowhawk, and Common Kestrel had also arrived to overwinter. Migrating Oriental Dollarbird and Grey-streaked Flycatcher were also present, along with good numbers of overwintering Brown Shrike, Arctic Warbler, and Eastern Yellow Wagtail.
In recent years the rice paddies on Yonaguni Island have decreased, so waders and plovers are sparse — just small numbers of Black-winged Stilt, Sharp-tailed Sandpiper, Common Snipe, Wood Sandpiper, Long-toed Stint, Common Sandpiper, and Red-necked Stint.
Common Emerald Dove, having finished breeding, formed small flocks and I watched them feeding on several occasions.
Chinese Sparrowhawk, juvenile. I also picked out several adults soaring.
