The overwintering small birds are increasing on Ishigaki Island.
Among them, I found a strange Daurian Redstart. At first I thought it might be a male juvenile transitioning into its first-winter plumage, but that doesn't seem to be the case — it's been suggested the bird may be a female-type individual with unusual plumage. Either way, it was an interesting Daurian Redstart.
Dusky Warblers appear to be arriving in decent numbers in the riverside thickets. Getting a good photo of them is not easy.
A fair number of Black-faced Buntings were lurking in the sugarcane fields. Some individuals that looked more like Masked Buntings were mixed in as well.
I thought the area around the throat might be partway through changing to adult male plumage, but it looks as though feathers have been lost, exposing the black area beneath. Even so, the whitish feathering from above the eye toward the cheek area looks like a male's.
That said, when Daurian Redstarts transition from juvenile to first-winter plumage, male individuals apparently develop vivid orange feathers. This individual shows some orange in places, but is otherwise brown.
